Bill Gates Calls for Shift in Renewable Energy Subsidies, But Reality May Be MoreComplex
Bill Gates, the co-chair of the Global Commission on Adaptation andfounder of Breakthrough Energy Ventures, has advocated for a shift in government subsidies from solar and wind energy to more nascent clean energy technologies. In an interview with MIT TechnologyReview, Gates argued that solar and wind energy have matured to the point where they can compete without subsidies, while technologies like energy storage and offshore wind still require governmentsupport to reach scale.
“These tax breaks should be shifted to more restrictive energy technologies, such as energy storage technology, offshore wind, and other areas where prices are still very high,” Gates said. “The sun can’t shine24 hours a day, and if you’re far from the equator, it’s hard to use solar energy in the winter. These methods only supply 25% of electricity. So we need to do a lot more.”
Gates’ call for a shift in subsidies reflects a growing recognition that while solar and wind energy have made significant strides in recent years, they face limitations in their ability to provide consistent, reliable energy. The intermittency of these sources, meaning they only generate power when the sun is shining or the wind is blowing, poses a significant challenge for integrating them into the grid.
Breakthrough Energy Ventures, a fund founded by Gates in 2016, has invested millions of dollars in startups developing solutions to these challenges. These companies include Quidnet, which uses abandoned oil and gas fields to store high-pressure water forlater use in generating electricity; Form Energy, which is developing a long-duration battery that can store energy from renewable sources; and Boston Metal, which is developing a carbon-free steelmaking process.
While Gates’ argument for shifting subsidies to more nascent technologies is compelling, the reality on the ground is more complex.Governments face limited resources for supporting clean energy development, and the need for continued investment in solar and wind energy remains critical.
The International Energy Agency (IEA) reported that global renewable energy capacity growth stalled in 2018 after two decades of strong expansion. The growth of solar, wind, hydro, bioenergy, and other renewables only increased by 180 gigawatts last year. According to the IEA’s Sustainable Development Scenario (SDS), renewable energy capacity additions need to average over 300 gigawatts per year between 2018 and 2030 to meet the goals of theParis Agreement.
The IEA’s Executive Director, Fatih Birol, expressed concern over the slowdown in renewable energy growth, noting that energy-related carbon dioxide emissions rose again in 2018, reaching a record high of 33 billion tonnes.
“These 2018 figures area cause for serious concern, but smart and decisive policies can put renewable energy back on a path of strong growth,” Birol said.
The IEA’s findings highlight the need for continued investment in solar and wind energy, even as new technologies are developed. While it is important to support innovation in areas like energy storageand offshore wind, prematurely shifting subsidies away from mature technologies could hinder the transition to a clean energy future.
Ultimately, the optimal approach to clean energy development will likely involve a balanced strategy that supports both mature and emerging technologies. Governments need to carefully consider the trade-offs involved in allocating limited resources and ensure that investments aremade in a way that maximizes the impact on reducing greenhouse gas emissions.
