The United States is a major global leader. On a gross domestic product basis, it is the world’s largest economy. And on a primary energy consumption basis, it is the world’s second largest energy system. The United States aims to achieve a carbon free power sector by 2035. This is both an inspiring and challenging objective. In 2023, 41% of the country’s electricity consumption came from decarbonized technologies: 23% from renewable energy and 18% from nuclear power. This report analyzes the energy transition in the American power sector. It finds that solar photovoltaic, wind, and battery storage economic and technological progress makes this ambition within reach. Key topics such as the Inflation Reduction Act, new industrial opportunities, electricity system reform, grid reinforcement and expansion, as well as the upcoming presidential elections are also included. Renewable Energy Institute hopes that this report will enrich the energy debate in Japan at a time when the country’s next Strategic Energy Plan is actively discussed.
