Varun Srinivasan Sivaram (born 1989) is an American physicist, clean energy executive, and former U.S. diplomat. He is Group Senior Vice President, member of the Group Executive Team, and Head of Strategy, Innovation, Portfolio, and Partnerships and M&A at Ørsted, a clean energy company with the world's largest offshore wind energy portfolio.^[3][4] He has previously served in the U.S. State Department as managing director for clean energy and senior advisor to U.S. Special Presidential Envoy for Climate John Kerry, as the chief technology officer (CTO) of ReNew Power, India's largest renewable energy company, on the faculty of Columbia University, as the director of the energy and climate program at the Council on Foreign Relations (CFR), and as a senior energy advisor to the mayor of Los Angeles and governor of New York.^{[4][5][6][7][8][9][10]}

Dr. Sivaram holds a B.S. in engineering physics and a B.A. in international relations from Stanford University, where he was awarded a Truman Scholarship. He also holds a PhD in condensed matter physics from the University of Oxford, St. John's College,^[1] where he was a Rhodes Scholar. While at Oxford, his research investigated the use of perovskite solar cells and was supervised by Henry Snaith.^[1][11]

Sivaram's professional experience spans the public, academic, and private sectors. He is currently Group Senior Vice President and a member of the Group Executive Team at Ørsted, where he oversees Group corporate strategy, the development and deployment of transformative technologies and digital innovations, portfolio strategy and capital allocation, and partnerships and M&A.^[3][4] He previously served in the administration of President Joe Biden as managing director for clean energy and senior advisor to the U.S. Special Presidential Envoy for Climate John Kerry, where he created the First Movers Coalition.^{[5][12][6][7]} His policy experience also includes serving as senior energy advisor to Los Angeles Mayor Antonio R. Villaraigosa and New York Governor Andrew Cuomo.^[13] In his academic career, he has served on the faculty of the Georgetown University School of Foreign Service and the Columbia University Center on Global Energy Policy. In the private sector, he served as the Chief Technology Officer of ReNew Power, a multibillion-dollar company that is India's largest producer of renewable energy, and was earlier a consultant for McKinsey & Co.^[14] Sivaram serves on the boards of the Atlantic Council and the Breakthrough Institute and is a World Economic Forum Young Global Leader and member of the Council on Foreign Relations.^[15][16][17] He has also served on the boards of the Stanford University Woods Institute for the Environment and Precourt Institute for Energy; as one of the 25 advisors to the UN COP26 climate conference in 2021, on the World Economic Forum's Global Future Council for the Energy Transition; as senior fellow at the Aspen Institute, ITIF, and Energy for Growth; and on the board of directors of Peridot Acquisition Corp. (NYSE:PDAC).^[14]

Sivaram is the author of Taming the Sun: Innovations to Harness Solar Energy and Power the Planet.^[18] Taming the Sun explores the potential of solar energy, the world's cheapest and fastest-growing power source, to one day supply most of the world's energy needs. Sivaram argues, however, that solar's current surge is on track to stall, dimming prospects for averting catastrophic climate change. Brightening those prospects, he concludes, will require innovation—creative financing, revolutionary technologies, and flexible energy systems.

Sivaram is also lead author of Energizing America: A Roadmap to Launch a National Energy Innovation Mission.^[19] Along with co-authors Colin Cunliff, David Hart, Julio Friedmann, and David Sandalow, Sivaram calls for the United States to triple federal funding for clean energy innovation to $25 billion by 2025 to speed global clean energy transitions and cultivate advanced U.S. energy industries that can compete in growing markets around the world. According to Bloomberg, "The book details down to the budget line item exactly how much money America should spend and how it should spend it."^[20]

Sivaram is the editor of Digital Decarbonization: Promoting Digital Innovations to Advance Clean Energy Systems.^[21] The volume brings together fourteen expert authors who lay out a wide range of areas in which digital technologies are promoting clean energy systems; caution about serious risks of digitalization to cybersecurity and privacy; and articulate actionable recommendations for policymakers in the United States and abroad to ensure that digital innovations help advance the fight against climate change.

Bill Gates has called Sivaram's 2016 essay on clean energy innovation in Foreign Affairs magazine "One of the best arguments I've read for why the U.S. should invest in an energy revolution."^[22] The Financial Times called his book Taming the Sun "the best available overview of where the industry finds itself today, and a road map for how it can reach that brighter future," and The Economist called it "prescient...and readable."^[23] His TED talk on India's clean energy transition has been viewed more than one million times.^[24] TIME Magazine named him to its inaugural TIME 100 Next list of the next hundred most influential people in the world; MIT Technology Review named him one of its top 35 innovators under 35; Forbes named him to its 30 under 30 in Law and Policy; Grist named him one of its top 50 leaders in sustainability; and PV Magazine called him "The Hamilton of the Solar Industry."^{[25][6][11][26]}
