35 Leading Thought Leaders on Renewable Energy

Introduction

The technology problem in renewable energy is largely solved. Solar panels are now the cheapest source of electricity in history. Wind turbines are being installed at a pace that would have seemed fantastical a decade ago. Global clean energy investment reached an estimated $2.2 trillion in 2025, with renewables alone accounting for roughly $780 billion of that figure. For every dollar spent on fossil fuels, the world is now spending $1.70 on clean energy. The ratio was 1:1 just five years ago.

What remains unsolved is not the technology. It is the leadership. The real challenges blocking the energy transition in 2026 are political courage, permitting reform, grid integration, workforce transition, and the mobilisation of capital into the Global South. These are human challenges, not engineering ones. The thought leaders who understand this, the people who sit at the intersection of energy systems and human systems, are the ones whose thinking genuinely matters right now.

This list was compiled to answer a question that most renewable energy reading lists ignore: not just who understands clean energy, but who understands the leadership of clean energy. That distinction matters more than it might seem. Understanding solar irradiance data does not prepare you for the political battle to reform permitting laws. Understanding wind turbine efficiency does not prepare you for the leadership conversation required to retrain a coal workforce. The 35 people on this list represent the full spectrum of what genuine leadership in renewable energy looks like in 2026, from policy architects and finance innovators to community advocates and frontline entrepreneurs who are getting things built in the hardest markets on earth.

According to the International Renewable Energy Agency, achieving the global goal of tripling renewable capacity by 2030 requires deploying roughly 1,000 gigawatts of new capacity every year between now and then. To put that in context, the world added around 300 gigawatts in 2023. The gap between ambition and delivery is not a technology gap. It is a leadership gap. These 35 people are working to close it, and following their thinking is one of the highest-leverage actions a leader in any sector can take right now.

Whether you lead an energy company, an investment fund, a government ministry, or simply an organisation that consumes power and cares about where it comes from, the voices on this list will help you think more clearly, decide more confidently, and lead your organisation through the most consequential transition of our era. Jonno White, experienced keynote speaker and leadership facilitator working with organisations around the world, helps leadership teams in the energy sector and beyond build the communication, accountability, and decision-making frameworks that the transition demands.

Why Leadership in Renewable Energy Matters

Every major shift in human history has required not just inventors but leaders. The Industrial Revolution required factory owners willing to retrain workforces. The digital revolution required executives willing to cannibalise their own business models. The clean energy transition requires something even harder: leaders willing to navigate political opposition, institutional inertia, financial uncertainty, and social resistance simultaneously, often without clear precedents to guide them.

The cost of ignoring renewable energy leadership thinking is not just environmental. According to the World Economic Forum's 2025 Energy Transition Index, countries with the strongest policy frameworks and leadership commitment are deploying renewable energy at three to four times the pace of countries with weak governance, regardless of solar and wind resource quality. Leadership quality is now a bigger determinant of clean energy deployment speed than geography. When organisations fail to engage with the best thinking in this space, they make decisions based on frameworks that were built for a different energy system and that are increasingly disconnected from where markets, regulation, and technology are heading.

How This List Was Compiled

The 35 people on this list were selected based on four criteria: demonstrated expertise in renewable energy or the clean energy transition, geographic and disciplinary diversity, active contribution to public discourse through published work, keynotes, or advocacy, and genuine impact on how the field is actually evolving. The list spans policy experts from Europe and the Global South, technology pioneers from Australia and Scandinavia, finance innovators from the United Kingdom and the Americas, and advocacy leaders from Africa and Asia. It includes researchers, chief executives, advocates, and practitioners. Together, they represent the breadth of thinking that anyone serious about renewable energy leadership needs to be engaging with in 2026.

Policy Architects and Institutional Leaders

These are the people whose decisions and analyses shape the frameworks within which renewable energy investment happens. From international agencies to national governments to the most widely-read research platforms in the field, they set the terms of the global conversation.

1. Fatih Birol

International Energy Agency

When governments and investors need to understand where global energy is heading, Fatih Birol is the person they consult first. As Executive Director of the International Energy Agency since 2015, he has overseen the transformation of an institution that once focused primarily on oil security into the world's most authoritative source of analysis on the clean energy transition. His World Energy Outlook is read by every serious energy policymaker on earth, and his calls to stop new fossil fuel investments, made in the IEA's landmark 2021 Net Zero by 2050 report, sent shockwaves through financial markets.

Under his leadership, the IEA expanded its membership to represent over 80% of global energy demand, fundamentally reshaping how its guidance is applied across both developed and emerging economies. Birol has been named to the TIME 100 list of the world's most influential people and recognised by the Financial Times as Energy Personality of the Year. His ability to translate complex energy economics into policy-relevant language for a global audience remains unmatched in the field.

2. Francesco La Camera

International Renewable Energy Agency (IRENA)

Few institutions have done more to make the case for renewable energy at the intergovernmental level than IRENA, and few leaders have shaped that case more consistently than Francesco La Camera. As Director-General of IRENA since 2019, he has directed the agency's focus toward what he describes as the "new energy system," one built on renewables rather than treating them as a supplement to fossil fuels. With over thirty years of experience in climate, sustainability, and international cooperation, he brings the institutional patience required to work across 171 member countries with wildly different energy starting points.

IRENA under La Camera's leadership produced the landmark Geopolitics of the Energy Transition report, which argued that the shift to renewables will fundamentally redraw global power relationships, reducing the leverage of fossil fuel exporting nations and creating new strategic advantages for countries with strong renewable resources and manufacturing capacity. That report has become required reading for foreign policy and energy strategy teams across the world.

3. Jan Rosenow

Regulatory Assistance Project / University of Oxford Environmental Change Institute

The most read energy thought leader on the global illuminem platform in 2024 was not a corporate executive or a government minister. It was a researcher who splits his time between the Regulatory Assistance Project and Oxford University's Environmental Change Institute, where he leads the Energy Programme. Jan Rosenow's value lies in an ability to do something rare in energy debates: change minds with evidence. His widely shared 2024 piece arguing that heating with hydrogen is still a fairy tale is emblematic of his approach, taking a received wisdom that had attracted billions in policy support and dismantling it, methodically, with data.

As a LinkedIn Top Voice, co-founder of the "Watt Matters" podcast, and advisor to the House of Commons on decarbonising heating, Rosenow operates across academic, policy, and public spheres with unusual fluency. He is among the top 25 energy influencers globally according to Onalytica, and has advised the IEA, the European Commission, the European Parliament, and the US Agency for International Development. For energy leaders who want rigorous thinking on European energy policy and electrification, following his output is essential.

4. Damilola Ogunbiyi

Sustainable Energy for All (SEforALL)

Named to the 2026 TIME Earth Awards alongside the world's most consequential climate leaders, Damilola Ogunbiyi is the most important voice in global energy access and the most powerful advocate for ensuring that the clean energy transition does not repeat the inequities of the fossil fuel economy. As CEO and UN Secretary-General's Special Representative for Sustainable Energy for All and Co-Chair of UN-Energy, she leads the most important coalition for SDG7 on the planet. Under her leadership, SEforALL has partnered with over 200 organisations, supported over 100 countries, and secured commitments of more than $1.6 trillion in energy finance.

Before her current role, Ogunbiyi was the first female Managing Director of Nigeria's Rural Electrification Agency, where she initiated the $550 million Nigerian Electrification Project, which has provided energy access to over 8 million people. Her argument, made consistently and compellingly, is that the global south has both the right and the capacity to leapfrog fossil fuels entirely if the world's financial institutions provide financing at fair cost of capital. She is one of the co-chairs of Mission 300, the joint World Bank and African Development Bank initiative to connect 300 million Africans to electricity by 2030.

5. Michael Liebreich

Liebreich Associates / EcoPragma Capital

The founder of Bloomberg New Energy Finance, Michael Liebreich has spent two decades as one of the sharpest, most provocative, and most analytically rigorous minds in the global clean energy conversation. He now chairs Liebreich Associates, co-manages EcoPragma Capital, and hosts the weekly "Cleaning Up" podcast, where he interviews clean energy, mobility, and climate finance leaders including Tony Blair and Ban Ki-moon. His twice-yearly presentations at Bloomberg's New Energy Finance Summit have become agenda-setting moments for the investment community.

In early 2026, Liebreich published "The Pragmatic Climate Reset," a two-part analysis in Bloomberg New Energy Finance arguing that despite political headwinds in the United States, the underlying economics and technology of clean energy make the transition mathematically inevitable. His willingness to challenge both fossil fuel incumbents and clean energy advocates who overstate their case, including on hydrogen for heating, has made him a trusted voice for readers who want analysis over advocacy. International travel is often far more affordable than expected, so organisations regularly bring global thinkers to their events. Email jonno@consultclarity.org to discuss how Jonno White works with energy sector leadership teams.

Energy Finance and Investment Leaders

Capital is the primary accelerant of the clean energy transition. These thought leaders understand how money moves toward or away from clean energy, and their thinking shapes where hundreds of billions of dollars flow.

6. Kingsmill Bond

Rocky Mountain Institute (RMI)

At the Rocky Mountain Institute, Kingsmill Bond has spent the last decade building one of the most compelling analytical frameworks for understanding why the clean energy transition is not just happening but is inevitable. His 2022 work "Rapid Solar and Wind Growth Calls Time on the Fossil Fuel Era," co-authored with Sam Butler-Sloss and others at RMI, demonstrated that fossil fuel demand in the electricity sector had already peaked in 95% of OECD countries, a finding that fundamentally reshaped how institutional investors model energy exposure.

Before joining RMI, Bond spent 25 years as a sell-side equity analyst and strategist at Deutsche Bank, Citibank, and Sberbank, giving him a financial markets fluency that most energy researchers lack. His Substack newsletter "Renewable Revolution" translates RMI's research into formats that investment professionals can apply directly. For anyone who needs to understand the investment logic of the energy transition, not just the idealism, Bond is an essential follow.

7. Gabriela Herculano

iClima Earth

The Colombian-born, London-based founder of iClima Earth occupies a distinctive niche at the intersection of climate finance and renewable energy investment. Through iClima Earth, she has built one of the world's first ETF products specifically designed to track companies that enable CO2e avoidance, not just those with low emissions, but those actively displacing fossil fuels. Her writing on the illuminem platform on energy transition, distributed renewable energy, and decarbonisation strategies has made her one of the most widely read voices in clean energy finance.

Herculano is also Managing Director at Invest and Grow Projects Ltd, and has written extensively on how financial products can be structured to provide investors with measurable, auditable environmental impact rather than greenwashing-prone ESG proxies. Her perspective is particularly valuable for finance professionals, institutional investors, and corporate treasury teams navigating the growing universe of climate-related investment products. She brings a Global South perspective to climate finance that is frequently missing from North Atlantic-dominated conversations about clean energy capital allocation.

8. Rachel Kyte

Tufts Fletcher School

A former Special Envoy for Climate Change at the World Bank and former CEO of Sustainable Energy for All, Rachel Kyte is one of the world's most experienced practitioners at the intersection of clean energy and development finance. She is now a Professor at the Tufts Fletcher School and one of the most authoritative voices on climate finance reform, particularly the need to restructure multilateral development bank financing to make clean energy affordable for developing countries.

Kyte's 2025 writing and speaking on the cost of capital gap for clean energy in Africa and South Asia has been cited by heads of government and finance ministers as among the most practically useful frameworks available for understanding why clean energy investment is not flowing to the places that need it most. Her grounding in both the practitioner world and academia gives her analysis an unusual combination of institutional credibility and operational realism.

9. Connor Teskey

Brookfield Renewable Partners

As CEO of Brookfield Renewable, one of the world's largest pure-play renewable energy companies with approximately 135 gigawatts of capacity in development and operation across six continents, Connor Teskey has an operational perspective on clean energy deployment that most thought leaders lack. His arguments are consistently grounded in economics: "Renewables remain the lowest-cost source of new electricity and the fastest to deploy and scale," he stated in multiple investor communications in 2025 and 2026, positioning renewable energy not as a climate concession but as the rational financial choice.

Teskey's thought leadership is particularly valuable because he operates at the scale where the real challenges of the transition, including grid connection, permitting, supply chain constraints, and long-term power purchase agreement structures, become visible. His writings and investor communications on the conditions required to deploy capital at scale are required reading for anyone in energy infrastructure investment.

10. Jigar Shah

Multiplier / Energy Empire Podcast

Few individuals have done more to translate clean energy technology into financed, deployed reality than Jigar Shah. As the founder of SunEdison, he pioneered the solar financing model that made rooftop solar accessible to ordinary homeowners and businesses. As co-founder of Generate Capital and the Carbon War Room, he helped build the infrastructure for clean energy project financing across dozens of markets. He is the author of "Creating Climate Wealth: Unlocking the Impact Economy," one of the most practically useful books on clean energy entrepreneurship and investment.

Shah's tenure overseeing the US Department of Energy's Loan Programs Office under the Biden administration, which ended in January 2025, saw the office supervise approximately $100 billion in finalised and conditional commitments for renewable energy, batteries, advanced nuclear, and clean technology manufacturing. He has since co-founded Multiplier in 2025 and co-hosts the "Energy Empire" and "Open Circuit" podcasts. His foundational argument, that clean energy is primarily a financing problem rather than a technology problem, continues to influence how practitioners around the world structure deals.

Scientists and Technology Pioneers

The researchers who have built the scientific and technical foundations of modern renewable energy, and who continue to push its frontiers.

11. Martin Green

University of New South Wales (UNSW)

Widely known as the "father of photovoltaics," Martin Green is the Scientia Professor at UNSW whose research has done more than any other to drive down the cost of solar panels. The silicon solar cell technologies his team developed, including the Passivated Emitter and Rear Contact (PERC) cell, now account for the vast majority of solar panels produced globally. He was awarded the Global Energy Prize in 2018 for his transformative contributions to solar energy technology, followed by the 2022 Millennium Technology Prize and, shared with three former students, the 2023 Queen Elizabeth Prize for Engineering.

Green's work is a rare example of academic research that has directly altered the economics of a global industry. Solar electricity is now cheaper than coal or gas in almost every market on earth, and a meaningful portion of that achievement traces back directly to his laboratory in Sydney. His ongoing research into next-generation perovskite solar cells, evidenced by multiple papers published in Nature Energy and Progress in Photovoltaics in 2025 and 2026, suggests the cost reductions may not be finished yet.

12. Henrik Stiesdal

StiesdaL A/S

The Danish engineer who helped develop the first commercial offshore wind farm, Vindeby, in 1991, remains one of the most creative and practically grounded minds in renewable energy technology. As former Chief Technology Officer at Siemens Wind Power, Stiesdal was responsible for technical development of wind turbines that are now installed in their millions across the world. He has since founded StiesdaL A/S, through which he is developing next-generation offshore wind, carbon capture, and green hydrogen technologies.

Stiesdal's "SubStation" floating offshore wind concept and his work on "GridScale," a thermal energy storage system that stores wind and solar power as heat, represent his ongoing commitment to solving the hardest remaining problems in the energy transition rather than resting on past achievements. He is one of the most cogent voices on the practical engineering limits of renewable energy scale-up, and his willingness to say what is genuinely hard distinguishes him from more optimistic advocates.

13. Mark Z. Jacobson

Stanford University

A Professor of Civil and Environmental Engineering at Stanford, Mark Z. Jacobson is the academic most closely associated with the argument that a 100% renewable energy system is not just possible but feasible and affordable. His landmark "Roadmap" papers, published with his team at Stanford's Atmosphere/Energy Program, provide jurisdiction-by-jurisdiction analysis of how each US state and each country can achieve 100% clean energy using only solar, wind, and water-based technologies.

Jacobson's work has been controversial in energy circles, with some researchers challenging his exclusion of nuclear energy and carbon capture from the solution set. His willingness to engage those challenges publicly, including in a high-profile dispute that resulted in a published rebuttal in the Proceedings of the National Academy of Sciences, has actually strengthened his credibility as a scientist who does not shy away from adversarial peer review. His Stanford research group continues to publish some of the most widely cited clean energy scenario modelling in the field.

14. Volker Quaschning

HTW Berlin

A Professor of Regenerative Energy Systems at the University of Applied Sciences in Berlin, Volker Quaschning has built one of the largest public science communication platforms in the German-speaking world on renewable energy and climate protection. His books on renewable energy systems have sold hundreds of thousands of copies and have been translated into multiple languages, making him one of the most successful translators of clean energy science for a general audience.

Quaschning's YouTube channel, social media presence, and public advocacy extend his influence well beyond academia. He is a founder of the "Scientists for Future" initiative in Germany, which mobilised thousands of German researchers in support of the climate movement. For anyone following German and European energy policy, where the political battles over coal phase-out, hydrogen strategy, and grid expansion are among the most consequential in the world, Quaschning provides essential context and analysis.

15. Jesse Jenkins

Princeton University

The lead researcher behind Princeton University's "Net Zero America" project, Jesse Jenkins is one of the most rigorous and practically grounded energy systems modellers working today. Now an associate professor at Princeton, his work produces granular, buildable pathways for net-zero energy systems in the United States and globally, with an attention to grid operations, infrastructure siting, and workforce transition that most energy scenario work lacks. He leads the REPEAT Project, which provides real-time, independent evaluation of US energy and climate policies as they are proposed and enacted.

Jenkins' work was recognised with inclusion on the 2024 TIME100 Next list of the next hundred leaders shaping the future, and the TIME100 Climate list of the most influential climate leaders. He co-founded Firma Power and co-hosted the "Shift Key" podcast on the transition away from fossil fuels from 2024 to 2026. His willingness to share models, data, and methodology openly and engage with critics across the political spectrum makes him one of the most intellectually generous academics in the field.

Climate Communication and Policy Advocates

Renewable energy leadership is not only built in laboratories and boardrooms. It is built in legislatures, newsrooms, and public squares. These thinkers have made the case for clean energy to audiences who need to be moved, not just informed.

16. Katherine Hayhoe

Texas Tech University / The Nature Conservancy

The Chief Scientist of The Nature Conservancy and a Professor at Texas Tech University, Katherine Hayhoe is widely regarded as the world's most effective communicator on the relationship between climate change and clean energy. Her approach, built on finding common ground across political and cultural divides rather than sharpening them, is grounded in both the science and the social psychology of how people change their minds. Her book "Saving Us: A Climate Scientist's Case for Hope and Healing" is one of the most widely read works on climate communication published in the last decade.

Hayhoe's inclusion on this list reflects a conviction that the communication of renewable energy leadership matters as much as the analysis of it. The gap between what science knows and what communities believe about clean energy is not primarily a technology problem. It is a communication and relationship problem. Few people alive understand that problem better or have done more to close it. For leaders in the energy sector who need to communicate the transition to sceptical stakeholders, following her work is not optional.

17. Leah Stokes

University of California Santa Barbara

A political scientist rather than an engineer, Leah Stokes brings something to the renewable energy conversation that most energy thought leaders do not: a rigorous understanding of why clean energy policy succeeds or fails at the legislative level. Her book "Short Circuiting Policy: Interest Groups and the Battle Over Clean Energy and Climate Policy in the American States" is one of the most forensic analyses of how fossil fuel lobbying defeats renewable energy legislation, and her work directly influenced the design of the Inflation Reduction Act.

Stokes is one of the most consistently accurate predictors of US energy policy developments and one of the most effective advocates for durable clean energy policy design. Her combination of political science rigour and genuine commitment to outcomes makes her unusually valuable for anyone trying to understand why the energy transition moves at different speeds in different political environments. She regularly shares analysis of legislative developments in the United States and is consistently one of the most engaged voices on clean energy policy on social media.

18. Tzeporah Berman

Stand.earth

The Co-Director of the Fossil Fuel Non-Proliferation Treaty initiative and a Senior Advisor at Stand.earth, Tzeporah Berman is the most persistent and influential campaigner for a binding international agreement to phase out fossil fuel production. Her argument, that individual country commitments to net zero emissions are meaningless without a framework that addresses supply as well as demand, has shifted from the fringes to the mainstream of climate policy debate over the last five years.

Berman's work has been credited with influencing the landmark language on "transitioning away from fossil fuels" adopted at COP28 in Dubai. Her ability to move between advocacy, policy negotiation, and public communication, combined with deep networks in both the climate movement and the energy finance world, makes her one of the most effective bridge-builders between civil society and institutional power. She is among the most active voices in the renewable energy thought leadership space on social media and regularly engages with followers across political and ideological divides.

19. Lauri Myllyvirta

Centre for Research on Energy and Clean Air (CREA)

The Lead Analyst at the Centre for Research on Energy and Clean Air, Lauri Myllyvirta has built a global reputation for providing the most rigorous, rapid, and reliable data on coal consumption and air quality impacts. His near-real-time tracking of coal burning in China, Europe, and globally has become a primary source for journalists, policymakers, and investors trying to understand whether the energy transition is actually happening or whether official statistics are masking slower progress.

Myllyvirta's 2024 analysis showing that China's carbon dioxide emissions peaked in 2023, years earlier than most official projections, was one of the most consequential pieces of energy analysis published in the last decade, immediately reshaping how the investment community and policy world think about Chinese energy transitions. He is among the most cited clean energy analysts on social media and produces some of the most rigorously sourced and clearly presented energy data available anywhere.

20. Dave Jones

Ember

As Global Insights Director at Ember, the UK-based energy data and analysis organisation, Dave Jones oversees the publication of some of the most widely downloaded clean energy data products in the world, including Ember's annual Global Electricity Review. His team's methodology for tracking the real-time share of renewables in global electricity generation has become a standard reference point for journalists, investors, and policymakers who need reliable, current data rather than projected estimates.

Jones is also one of the most effective communicators of energy data trends, translating complex generation statistics into narratives that non-specialists can understand and act on. His work consistently challenges the tendency to focus on installed capacity targets rather than actual generation progress, and his willingness to name the gap between political commitment and deployed reality is a valuable corrective in a space prone to greenwashing and optimism bias.

Energy Access and Equity Leaders

The clean energy transition will not be complete, and may not be stable, unless it is equitable. These thought leaders are building the intellectual and practical case for an energy transition that leaves no community behind.

21. Wanjira Mathai

World Resources Institute

The daughter of Nobel Peace Prize laureate Wangari Maathai and a Managing Director at the World Resources Institute, Wanjira Mathai brings to renewable energy leadership a perspective shaped by decades of working on the intersection of environmental justice, community empowerment, and clean energy access in sub-Saharan Africa. Her advocacy connects the green economy to the everyday lives of people who depend most directly on land, water, and energy for their survival.

Mathai co-authored the "Africa Greentech" report with the World Resources Institute, one of the most comprehensive assessments of the clean energy opportunity for African economic development. Her work emphasises that Africa's renewable energy transition must be led by African institutions and communities rather than designed in Washington or London and exported. Her voice is essential for organisations working on clean energy investment, development finance, or sustainability strategy in sub-Saharan Africa.

22. Arunabha Ghosh

Council on Energy, Environment and Water (CEEW)

The Founder and CEO of the Council on Energy, Environment and Water, India's leading clean energy think tank, Arunabha Ghosh is one of the most important voices on how the world's most populous country is navigating the energy transition. Under his leadership, CEEW has produced landmark research on India's renewable energy potential, the economic case for a clean energy transition in South Asia, and the financing gaps that prevent developing countries from deploying clean energy at the scale their climate commitments require.

Ghosh has advised the G7, the G20, and the United Nations on energy and climate policy, and his co-authorship of "Energizing India" with Rahul Tongia is one of the most credible analyses available of what it would actually take for India to achieve its ambitious clean energy targets. His perspective is particularly valuable at a moment when India has surpassed 40% of its installed electricity capacity from renewable sources, years ahead of its 2030 target, but still faces enormous challenges in grid integration, financing, and just transition for coal-dependent communities.

23. Sunita Narain

Centre for Science and Environment (India)

The Director-General of the Centre for Science and Environment in New Delhi, Sunita Narain has spent three decades as the most influential voice in India on the intersection of environmental justice, climate change, and energy access. Her argument, made consistently and with considerable courage given the political pressures in India's energy sector, is that the clean energy transition must address energy poverty that affects hundreds of millions of people simultaneously with addressing carbon emissions, and that one cannot be sacrificed for the other.

Narain co-authored the "First, Second, Third World" framework for understanding differentiated responsibilities in global climate action, an approach that has shaped India's diplomatic position in multilateral climate negotiations. Her annual "State of India's Environment" reports are among the most widely read environmental analysis documents in South Asia. For anyone working on energy transition in developing economies, her work is essential reading.

24. Michelle Arellano-Meza

World Energy Council

The Manager of the Future Energy Leaders programme at the World Energy Council, Michelle Arellano-Meza is one of the most articulate voices on what it means to lead the energy transition from the Global South, and specifically from Latin America. Born in Ecuador, she has built a career at the intersection of energy sustainability, climate change, and international affairs that gives her an unusually multidisciplinary perspective in a field prone to technical siloes.

Her most read piece on illuminem in 2024, "The future is now: A youth-led energy transition," argued that the energy transition cannot be led by the same institutional actors that built the fossil fuel economy, and that genuinely new leadership, younger, more diverse, and more attuned to the communities bearing the heaviest costs of climate change, is the necessary ingredient for real change. She is one of the most consistent voices for intergenerational equity in energy leadership.

25. Leila Benali

African Energy Commission

Serving as Morocco's Minister of Energy Transition and Sustainable Development from 2021 to 2024, Leila Benali brought extraordinary technical depth and political savvy to one of the world's most ambitious clean energy transitions. Morocco set a target of 52% renewable electricity by 2030 and made faster progress toward that target than almost any other developing country, in no small part due to the policy frameworks and investment conditions built under her ministerial leadership. She has since taken up leadership of the African Energy Commission.

Benali's work on the geopolitics of the energy transition in the Arab world and Africa, including her analysis of how North Africa can become a major green hydrogen exporter to Europe, has influenced billions in investment decisions and EU energy strategy. Her voice is essential for anyone working on energy transition in the Middle East, North Africa, or the intersection of European and African energy markets. She is actively engaged in public discourse and speaks at major international energy conferences.

26. Anika Molesworth

Farmers for Climate Action (Australia)

An Australian farmer, veterinarian, and founder of Farmers for Climate Action, Anika Molesworth occupies a space in the clean energy conversation that almost no one else does: the perspective of rural and agricultural communities who are simultaneously most vulnerable to climate change, most dependent on reliable and affordable energy, and most likely to be overlooked in energy transition planning dominated by urban and industrial perspectives.

Her book "Our Sunburnt Country" is one of the most personal and compelling accounts of what climate change is already doing to Australia's agricultural communities, and her advocacy work has helped bring the farming sector into the renewable energy conversation as a stakeholder rather than merely a bystander. For energy leaders designing rural electrification, agrivoltaics projects, or clean energy programs for regional communities, her perspective is invaluable and her voice is unique.

Energy Transition Strategists

These thought leaders specialise in making the overall strategic logic of the energy transition legible, connecting technology, finance, policy, and social systems into coherent frameworks for action.

27. Frank Wouters

MENA Hydrogen Alliance

The Chairman of the MENA Hydrogen Alliance and former Deputy Director-General of IRENA, Frank Wouters is one of the most experienced practitioners in the global renewable energy space, with three decades of work across government institutions, multilateral agencies, and private sector projects. His focus on green hydrogen as a complement to electricity-based decarbonisation, particularly in the Middle East and North Africa, gives him a perspective on the energy transition that few others combine with his level of direct implementation experience.

Wouters is one of the most widely read energy thought leaders on the illuminem platform, where his analysis of hydrogen strategy, energy storage, and the role of the Middle East in the global energy transition is regularly among the most shared content on the site. He is also a key lecturer for renewable gas and hydrogen at the New Energy Business School, making him a bridge between academic, policy, and practitioner communities.

28. Tony Seba

RethinkX

The co-founder of RethinkX and the author of "Clean Disruption of Energy and Transportation," Tony Seba is the most consistently and ambitiously bullish analyst on the speed of the clean energy transition. His technology disruption framework, which applies S-curve adoption models from previous technology transitions to solar, wind, batteries, and electric vehicles, produces forecasts that look radical compared to official IEA scenarios but have repeatedly proven more accurate.

His work on "Disruption of Energy," published with RethinkX in 2017, forecast that solar and wind would become the dominant sources of global electricity before 2030, a prediction that has come remarkably close to accurate ahead of schedule. For strategic planners and investors who want to understand the maximum rate at which the energy transition can unfold, Seba's scenarios are the most useful reference point, even for those who disagree with his assumptions.

29. Ramez Naam

Writer and Investor

A former computer scientist and Microsoft executive turned clean energy analyst and investor, Ramez Naam has built one of the most rigorous and widely-cited bodies of work on the exponential cost declines in solar, wind, and battery storage. His work on "learning curves" and "Wright's Law" applied to clean energy technologies established an analytical framework that is now standard in the energy modelling community, demonstrating that clean energy costs follow predictable and rapid decline trajectories regardless of policy support.

Naam's book "The Infinite Resource: The Power of Ideas on a Finite Planet" and his widely shared series of posts on solar prices, energy storage, and the pace of the energy transition have reached millions of readers and directly shaped how investors and analysts model clean energy economics. He is one of the most effective bridge-builders between the technology community and the energy investment world.

30. Kristina Skierka

Power for All

The CEO and founder of the Power for All campaign, Kristina Skierka is the most persistent and effective advocate for the argument that distributed renewable energy, mini-grids, solar home systems, and mobile solar farms, is not a marginal solution for remote communities but a viable path to universal energy access that could end energy poverty faster and more cost-effectively than centralised grid extension. Her campaign coordinates international and country-level efforts in East and West Africa and India.

Skierka has co-authored "Utilities 2.0: Reimagining Utilities as a Way to End Energy Poverty," one of the most analytically rigorous proposals for how traditional utility business models must change to serve energy-poor communities. She is a long-serving member of the United Nations Technical Advisory Group for SDG7 and a recipient of the 2022 Real Leaders Eco Innovation Award. Her thinking is essential for anyone working on rural electrification, development finance, or the last mile of the energy transition.

Wind, Regional, and Emerging Voices

These thought leaders are building renewable energy leadership capacity and deployment in sectors and regions that are often underrepresented in the global conversation, but whose decisions will determine whether the transition is truly global.

31. Philipp Schröder

1KOMMA5°

The CEO and founder of 1KOMMA5°, Philipp Schröder is building one of the world's fastest-growing distributed energy companies, integrating solar panels, battery storage, and heat pumps for residential and small commercial customers across Germany and Europe. As a former Country Director for Tesla in Germany and Austria and former Managing Director of sonnen, he brings a unique combination of large-company execution experience and entrepreneurial urgency to the challenge of deploying clean energy at household scale.

Schröder's argument, consistently made through public commentary and company growth, is that the clean energy transition happens house by house, building by building, and that the companies which make that process easy and integrated will capture enormous value while accelerating decarbonisation at scale. His perspective on the consumer-facing dimensions of the energy transition, including financing, installation quality, and customer experience, is largely absent from most thought leadership that focuses on utility-scale projects and policy.

32. Robin Mills

Qamar Energy

The CEO of Qamar Energy, one of the Middle East's most respected energy consultancies, Robin Mills is a non-resident fellow at Columbia University's Center on Global Energy Policy and the author of "The Myth of the Oil Crisis." His expertise spans the full spectrum from oil and gas economics through to the renewable energy transition, giving him a perspective that is rare and valuable: the ability to understand the energy transition as the incumbent fossil fuel world actually experiences it, not just as transition advocates present it.

Mills has been one of the most read energy thought leaders on the illuminem platform and is a regular commentator on energy policy and geopolitics across the Middle East, where the intersection of massive fossil fuel revenues and rapidly falling renewable energy costs is creating some of the most complex strategic decisions in the global energy system. His willingness to challenge both fossil fuel incumbent denial and clean energy advocate oversimplification makes him a uniquely balanced voice.

33. Nigel Topping

FSD Africa / High Level Climate Champions

As High Level Climate Champion for COP26 and subsequently a Senior Advisor to FSD Africa, Nigel Topping is the person most responsible for building the voluntary corporate commitment framework through which thousands of companies globally have made net zero pledges, including the Race to Zero campaign. His work connecting corporate climate pledges to the Glasgow Financial Alliance for Net Zero helped mobilise over $130 trillion in private capital behind the net zero commitment.

Topping is also an honorary professor of economics at Exeter University, a non-executive director at the UK Infrastructure Bank, and a board member of the ICE Benchmark Administration. His ability to operate simultaneously in advocacy, finance, and policy makes him one of the most connected thought leaders in the clean energy space. For organisations navigating corporate sustainability commitments and the relationship between net zero pledges and renewable energy procurement, his thinking is directly applicable.

34. Joanna Lewis

Georgetown University

A Professor of Energy and the Environment at Georgetown University, Joanna Lewis is the leading academic voice on Chinese clean energy policy and technology, and one of the most important analysts of the intersection between US-China relations and the global energy transition. Her book "Green Innovation in China" is the definitive academic treatment of how China moved from a follower to a leader in solar and wind energy technology, a shift that now shapes the entire global economics of clean energy.

China now manufactures approximately 80% of the world's solar panels and is the largest market for electric vehicles, wind turbines, and grid-scale batteries. Understanding how Chinese industrial policy, trade strategy, and domestic clean energy investment work is essential for any serious energy transition strategist. Lewis provides that understanding with an academic rigour that policy-facing analysts and journalists typically cannot match.

Notable Voices We Almost Included

Several candidates were considered seriously for this list but did not make the final 35. Alok Sharma, who led COP26 as UK Secretary of State for Business, Energy and Industrial Strategy, has exceptional credibility from his role in the Glasgow climate negotiations but has reduced his public output since leaving government in 2023. Assaad Razzouk, the Lebanese-Singaporean CEO of Gurín Energy and author of "Saving the Climate Without the Bulls**t," has built a highly engaged following on LinkedIn but his recent public output has focused more on advocacy than analysis. Mark Carney, whose climate finance work has been globally influential, operates primarily at the policy and financial system level rather than specifically in renewable energy leadership.

Mariana Mazzucato, whose mission economy framework has directly influenced clean energy industrial policy in Europe and the United States, is one of the most important intellectual influences on the field but is more influential in economics than in energy specifically. Naomi Oreskes, the Harvard science historian whose work on the manufactured doubt around climate science is essential background reading, has slowed her public profile recently. These five people are worth following, and their work is worth knowing, but each was ultimately outscored for this list by the people above.

Common Mistakes When Engaging with Renewable Energy Thought Leadership

The most common mistake leaders make when engaging with renewable energy thought leadership is confusing the technology story with the leadership story. Reading about declining solar costs or record wind installations is valuable, but it creates a passive optimism that is not the same as being equipped to lead. The question for any organisation is not whether renewable energy is winning globally. The question is what that transition means for your specific decisions, in your specific market, at your specific moment. That requires much more targeted engagement with thought leaders who are working on your particular challenges.

The second mistake is following thought leaders whose credibility comes from past achievement rather than current engagement. The energy transition is moving fast enough that analysis from even three years ago may be dangerously outdated. Several major forecasting organisations, including some that appear credible, are still using models built on assumptions about solar and wind cost trajectories that have been overtaken by reality. When assessing whether a thought leader is worth following, ask whether their most recent published work is from 2024 or 2025. If the most prominent content on their website or LinkedIn is from 2021 or earlier, find someone who is working in the present tense.

The third mistake is following thought leaders without building a curated, diverse portfolio. The energy transition looks completely different from the perspective of a Nairobi-based energy access entrepreneur, a London-based clean energy investor, a Berlin-based energy policy researcher, and a Queensland-based farmer installing solar. A reading diet that is dominated by any one of these perspectives will produce systematic blind spots. Deliberately seek out perspectives from geographies, disciplines, and communities different from your own professional world.

The fourth mistake is treating thought leadership as a substitute for action. The people on this list are worth following because they generate insights that change how organisations make decisions. But the value is in the decisions, not the following. Build a personal system for translating the insights you gather from these thinkers into questions you ask in your next strategy meeting, analyses you commission, investments you propose, or conversations you initiate.

The fifth mistake is following only the loudest voices. Several of the most important thought leaders on this list, including Jan Rosenow, Lauri Myllyvirta, and Kingsmill Bond, have reached their influence primarily through rigorous, evidence-based work rather than charismatic personal branding. Their output is often denser and less immediately accessible than the more public figures on the list, but it is also more analytically reliable. Balance accessibility with rigour when building your thought leadership portfolio.

Implementation Guide: Building Your Renewable Energy Knowledge System

Following thought leaders is only valuable if it produces usable knowledge. Here is a practical approach to building a renewable energy thought leadership knowledge system that actually supports better decisions.

The first step is to identify your specific knowledge gaps. Before adding anyone to your reading list, get clear on the questions that matter most for your organisation. Are you primarily trying to understand policy risk in your operating markets? Then prioritise voices like Jan Rosenow for European markets, Leah Stokes for US policy dynamics, and Arunabha Ghosh for South Asian perspectives. Are you focused on clean energy investment strategy? Then Kingsmill Bond, Gabriela Herculano, and Connor Teskey belong at the top of your list.

The second step is to build your listening infrastructure. Most of the thought leaders on this list are most active on LinkedIn, but several produce their best work through other channels. Michael Liebreich's "Cleaning Up" podcast is one of the most substantive long-form discussions of clean energy leadership available anywhere. Jesse Jenkins co-hosted the "Shift Key" podcast on the energy transition. Jan Rosenow and colleagues co-host "Watt Matters." Kingsmill Bond's Substack "Renewable Revolution" publishes his full analytical reports in accessible form.

The third step is to create a weekly review practice. Block 30 minutes each week specifically to review the most recent outputs from your priority list of five to ten thought leaders. Do not try to consume everything. The goal is a regular, curated engagement with the best current thinking rather than a firehose of information. Use a simple bookmark system to capture insights that connect directly to current organisational decisions.

The fourth step is to build in diversity deliberately. If your reading list of ten thought leaders is more than 60% from one region, one discipline, or one type of organisation, you have a blind spot that is likely to produce overconfident conclusions. Set a rule: at least 30% of your thought leadership portfolio must come from geographies or communities different from your primary operating context. The energy transition is genuinely global, and organisations that treat it as a North Atlantic phenomenon will be surprised by what happens in China, India, Africa, and Latin America over the next decade.

The fifth step is to engage, not just consume. Every person on this list is a human being who reads their LinkedIn mentions and values genuine engagement. If a piece of analysis by Dave Jones or Michelle Arellano-Meza directly influences a decision you make, tell them. The thought leadership community around the energy transition is remarkably accessible compared to most fields, and the relationships built through genuine engagement often yield more insight than the published output alone.

Frequently Asked Questions

What makes someone a thought leader in renewable energy?

A genuine thought leader in renewable energy is someone who is actively generating new analysis, frameworks, or approaches that change how other practitioners, policymakers, or investors think and decide. This is different from someone who is simply well-known for past achievements, or someone who primarily curates and shares others' ideas. The 35 people on this list are thought leaders in this active sense. They are currently producing work that is influencing the field's direction, not just providing commentary on developments that others are driving.

How do I follow renewable energy thought leaders effectively?

The most effective approach is to build a focused portfolio of five to ten thought leaders whose work is directly relevant to your most important questions, and to follow them across multiple channels rather than relying on any single platform. LinkedIn is the most commonly active platform for the people on this list, but many also publish through Substack, produce podcasts, or publish regularly in Bloomberg, Financial Times, or specialist platforms like illuminem and Carbon Brief. Combining multiple channels gives you a more complete picture of their thinking.

How was this list compiled?

This list was compiled by assessing genuine contribution to the field of leadership in renewable energy against four criteria: demonstrated expertise, active public output, geographic and disciplinary diversity, and direct impact on how the field is evolving. The final 35 represents a deliberately diverse sample spanning six continents, seven disciplinary traditions including policy, finance, engineering, communication, advocacy, academia, and entrepreneurship, and organisations ranging from international agencies to solo practitioners.

What is the single most important insight from this list about renewable energy leadership?

The single most important insight is that the technology problem in renewable energy is largely solved, and the leadership problem is not. The pace at which clean energy is deployed depends far more on political leadership, financing structures, permitting frameworks, and community engagement than it does on further improvements in panel efficiency or turbine output. The thought leaders on this list who are working on those human and institutional dimensions of the transition, particularly Damilola Ogunbiyi, Jan Rosenow, Leah Stokes, and Rachel Kyte, are addressing the transition's hardest remaining challenges.

Can I hire someone to facilitate renewable energy leadership workshops or sessions for my team?

Jonno White, Certified Working Genius Facilitator and bestselling author of Step Up or Step Out with 10,000+ copies sold globally, works with leadership teams in the energy sector and beyond to build the communication, decision-making, and alignment frameworks that enable them to lead complex transitions effectively. Whether your team is navigating a corporate sustainability strategy, organisational change driven by the energy transition, or a leadership offsite focused on long-term strategy, Jonno's keynotes and facilitation sessions provide the practical frameworks to translate insight into action.

Email jonno@consultclarity.org. Many organisations find that international travel costs are far lower than expected.

How often should I update my thought leadership portfolio?

The energy transition is moving fast enough that a significant review every six months is appropriate. New voices are emerging, established voices are shifting their focus, and the most important questions are changing rapidly. The list above was compiled in 2026, and several entries, particularly those in government or multilateral roles, may have changed by the time you read this. Treat any list as a starting point for your own ongoing research rather than a static reference.

Are there thought leaders specifically focused on Australia and the Asia-Pacific region?

The list includes Martin Green from UNSW, one of the world's most important solar technology researchers based in Sydney, and Anika Molesworth, who focuses on rural and agricultural community perspectives on the clean energy transition in Australia. The broader Asia-Pacific renewable energy transition is covered through Arunabha Ghosh on India, Joanna Lewis on China, and Robin Mills on the Middle East.

Final Thoughts

The clean energy transition is the defining leadership challenge of our era. It requires the kind of leadership that most management development programmes have never been designed to produce: leadership that is comfortable with deep uncertainty, capable of spanning enormous institutional diversity, committed to equity as well as efficiency, and willing to challenge incumbents with enormous political and financial power. The 35 people on this list have chosen, in their different ways, to try to provide that kind of leadership.

Following their thinking is a starting point. But the real work is in your own organisation, in the decisions you make and the conversations you lead and the culture you build. The ideas on this list are only as valuable as the action they produce.
