Renewable Energy’s Future: Challenges and Opportunities
The 2025 MIT Energy Conference brought together experts to discuss the future of renewable energy. Despite unprecedented investment in recent years, the industry faces uncertainty due to potential cuts in government subsidies. To compete with fossil fuels, renewable energy technologies must become more cost-effective and scalable.
The Current State of Renewable Energy
Brian Deese, an MIT Institute Innovation Fellow, emphasized the need for a level playing field for renewable energy technologies. He noted that clean energy investment in the United States reached an all-time high of $272 billion in 2024, but announcements of future investments have slowed down. Deese also highlighted the challenges of building out clean energy infrastructure due to high uncertainty, interest rates, and tariff rates.
The Role of Technology in Renewable Energy
Artificial intelligence (AI) can catalyze green energy breakthroughs, but it also puts a strain on existing infrastructure. Lucia Tian, head of clean energy and decarbonization technologies at Google, stated that her company is committed to building digital infrastructure responsibly and catalyzing the development of clean energy infrastructure. The cost-per-unit and scalability of clean energy technologies will ultimately determine their fate.
Public Policy and Government Investment
Vanessa Chan, a former U.S. Department of Energy (DoE) official, warned about the impact of public policy on the renewable energy industry. She noted that cutting funding for indirect research costs can have "knock-on" effects on academic institutions. Maria Robinson, former director of the DoE’s Grid Deployment Office, emphasized the need for government investment in grid modernization to meet growing power demand.
Emerging Clean Energy Technologies
The conference featured panels on emerging clean energy technologies, including hydrogen power, geothermal energy, and nuclear fusion. Alex Creely, a chief engineer at Commonwealth Fusion Systems, explained that fusion is safer and potentially more economical than traditional nuclear power. Quinn Woodard Jr., senior director of power generation and surface facilities at Fervo Energy, discussed how his company is making geothermal energy more economical through standardization and innovation.
Collaboration and Scaling
Several speakers stressed the need for academia, industry, and government to collaborate in pursuit of climate and energy goals. Amy Luers, senior global director of sustainability for Microsoft, compared the challenge to the Apollo spaceflight program and emphasized the need for academic institutions to focus on scaling and spurring investments in green energy.
The Road Ahead
The renewable energy industry faces challenges, but experts are optimistic about the potential for growth and innovation. Hannan Happi, CEO of Exowatt, noted that electricity is a commodity, and customers care about availability and affordability. Melissa Zhang, principal at Azimuth Capital Management, warned that green energy technologies may not receive significant support at the federal level in the near future.
Conclusion
The 2025 MIT Energy Conference highlighted the challenges and opportunities facing the renewable energy industry. While there are concerns about government subsidies and public policy, experts are optimistic about the potential for technological innovation and collaboration to drive growth and scalability.
