Eric Toone, a technical lead at Breakthrough Energy Ventures, discusses the critical role of energy in economic growth, especially in developing nations. He emphasizes the urgent need for innovative and affordable clean energy solutions to meet soaring demand. The conversation highlights the potential of nuclear power, geothermal energy, and the promising future of green hydrogen. Additionally, Toone explores the complexities of transitioning to sustainable energy while balancing economic development and environmental impact, urging a robust investment strategy.
Energy is crucial for economic growth, particularly in developing countries where access directly impacts quality of life and prosperity.
Electrifying sectors dependent on fossil fuels is essential but presents challenges in ensuring reliability and avoiding increased emissions due to intermittent renewable sources.
Nuclear and geothermal energy, alongside innovative hydrogen solutions, are pivotal for a clean energy future but require significant investment and public acceptance to overcome historical challenges.
Deep dives
The Role of Energy in Prosperity
Energy is fundamentally tied to economic growth, as it influences manufacturing, transportation, and overall human development. Historical data reveals a strong correlation between energy consumption per capita and per capita GDP across nations and over time. This has significant implications, particularly for developing countries where energy access directly impacts quality of life. As fossil fuels have powered much of the prosperity seen in developed nations, there is now a pressing need to find sustainable energy solutions that can support global development without exacerbating climate change.
The Challenge of Energy Transition
The impending challenge lies in electrifying various sectors currently relying on fossil fuels, such as transportation and manufacturing, while ensuring energy reliability. Solar and wind energy present intermittent sources, leading to potential energy shortfalls that can compel reliance on fossil fuels for backup, as observed in countries like Brazil and Germany during droughts and low wind conditions. This creates a paradox where the pursuit of renewable energy transition could inadvertently increase emissions if not managed effectively. The emphasis must be on developing reliable grid systems capable of integrating renewable sources without compromising energy availability.
Financial Barriers to Clean Energy Adoption
The disparity in energy costs presents a critical barrier for developing nations striving for prosperity through clean energy sources. Clean electricity alternatives may present higher costs compared to conventional fossil fuels, discouraging their adoption, especially when immediate economic needs are at stake. The concept of a 'green premium' highlights the additional costs associated with clean technologies, emphasizing the importance of reducing these costs to make clean energy a viable option for poorer regions. A successful transition will require addressing these economic challenges to prevent reliance on cheaper, carbon-heavy energy sources.
The Importance of Nuclear and Geothermal Energy
Nuclear energy has historically provided about 10% of the world's electricity, yet its expansion has faced challenges concerning safety, costs, and public perception. With new reactor designs and an increasing understanding of advanced nuclear technology, nuclear power could play a significant role in providing baseload, carbon-free energy. Additionally, geothermal energy is emerging as an underutilized resource, capable of regional expansion through improved drilling technologies and reservoir management. Both nuclear and geothermal sectors require concerted innovation and investment to establish them as key components of a clean energy future.
The Future of Hydrogen and Transportation Decarbonization
Hydrogen stands out as a versatile energy carrier, with its potential hinging on cost-effective production methods. The emergence of natural hydrogen, discovered through drilling in regions like Mali, opens possibilities for accessible hydrogen resources that could fuel various applications at competitive prices. However, decarbonizing the transportation sector presents challenges, particularly with passenger vehicles and heavy-duty transport continuing to rely heavily on liquid fuels. The integration of electric and other clean technologies in this sphere will be complex and requires strategic planning to meet growing global energy demands sustainably.
Energy is fundamental to economic development. It propels manufacturing, transportation, and construction, and throughout history, it’s been the driver of human prosperity. But as global population continues to increase, and countries develop, energy use could double by the end of this century—with much of that increase concentrated in the developing world.
Meeting that demand while ensuring we stay on track to reach a net- zero future is a massive challenge. It means leveraging both new innovations and scaling up the technologies that are already available. It also means increasing investment, as emerging markets and developing economies outside China account for only around 15% of clean energy spending.
Why is energy a critical enabler of development? What would it mean to electrify everything, and is that even possible? And what role will existing technologies like nuclear power play in a net-zero world?
This week, a re-run of host Jason Bordoff’s conversation with Eric Toone from July of this year where they discussed the challenges of increasing energy access in the developing world while rapidly cutting emissions.
Eric is the technical lead on the Investment Committee at Breakthrough Energy Ventures. Before joining Breakthrough in 2017, he was the vice provost and director of the Duke University Innovation and Entrepreneurship Initiative, and a professor of chemistry and biochemistry. From 2009 to 2012 he was detailed to the U.S. Department of Energy’s Advanced Research Projects Agency, where he served as program director and deputy director for Technology.
