The U.S. Department of Energy (DOE), through the Office of the Under Secretary for Infrastructure, is focused on working across the public and private sectors to help the U.S. transition to the clean energy economy.

With more than $97 billion in investments through the Bipartisan Infrastructure Law and the Inflation Reduction Act, DOE is embarking on a new era focused on the rapid commercialization, demonstration, and deployment of clean energy technologies. DOE is playing a critical role in efforts to rapidly lower energy costs, slash carbon emissions, and create new industries with the high-quality union jobs that are guaranteed to boost domestic manufacturing capabilities while strengthening U.S. global competitiveness.

Through the implementation of these historic federal investments in clean energy infrastructure, DOE is turbocharging U.S. climate action, moving the nation toward industrial decarbonization and driving down costs for the rapid deployment of cheap, clean, energy technologies available right now, and made right here, in America.


Americans spend over $400 billion each year to power our homes and commercial buildings, which consume 40% of the nation's total energy. Investments in efficient buildings will help us do more with less energy, alleviate pressure on our electric grid, allow for greater use of renewable and sustainable energy supplies, and ensure that we have available reliable energy supplies well into the future.

Carbon Management

Central to achieving net-zero emissions by 2050 is the economy-wide deployment of carbon management technology and infrastructure—across the entire value chain of carbon capture, removal, conversion, transport, and storage. DOE is delivering real-world carbon management solutions to meet U.S. climate goals, ensure energy security and reliability, and create good-paying jobs. Through these solutions, we also have the opportunity to ensure climate justice and environmental protection for communities that have been disproportionately impacted by fossil fuels.

Hydrogen is a versatile clean energy fuel that ensures we get the most out of dynamic and domestic energy resources, including wind, solar, and nuclear energy. By investing in the development of a hydrogen industry in the United States, we are slashing emissions from carbon-intensive sectors and opening a world of economic opportunity to clean energy businesses and workers across the country.

Electric Grid

Many pathways exist for the U.S. to meet our clean energy goals, but they all require upgrading and expanding our aging transmission infrastructure. Our strategic investments will accelerate the deployment of new transmission lines to connect Americans to cleaner, cheaper electricity; improve the resilience and reliability of the grid; and protect against disruptions due physical and cyberattacks or climate-induced extreme weather – all while helping achieve the President’s goal of 100% carbon pollution-free electricity by 2035.

Energy Storage

Energy storage solutions are transforming the electric power industry and helping to accelerate the full decarbonization of the electric grid. Energy storage projects will improve the reliability of transmission and distribution systems, especially in traditionally high-energy cost rural areas; more efficiently supply energy at peak periods of demand on the grid; and increase use of existing equipment, postponing or eliminating the need for costly upgrades.

Energy Supply

Diversifying our nation’s energy by investing in clean sources like hydroelectric and nuclear power helps us avoid energy disruptions, strengthen our energy security, and provide reliable clean energy power to millions of households. Investments in our clean energy future hold enormous potential to lower emissions, create new jobs, and build an even stronger economy.

Manufacturing and Energy Supply Chains

In February 2022, DOE published “America’s Strategy to Secure the Supply Chain for a Robust Clean Energy Transition.”  This is part of a whole-of-government approach for revitalizing the U.S. economy and domestic manufacturing. It includes more than 60 actions both the federal government and Congress can take to help the US capture the economic opportunity inherent in the energy sector transition. DOE is working with other federal agencies and Congress to advance this strategy.

Research & Development

DOE is delivering the next generation of innovative and carbon-reducing clean energy technologies and strengthening U.S. global competitiveness by putting our nation's scientists and researchers at the forefront of world class research and development. Advancing technologies from the lab to the marketplace, will boost the nation’s clean energy infrastructure and turbocharge U.S. climate action with the highest-impact solutions, so that we can move toward industrial decarbonization, promote environmental justice, and drive down the costs for the rapid deployment of cheap, clean energy across America.

Public Partners

In partnership with state, Tribal, and local governments and other community-based organizations, we are bolstering clean energy deployment. Highly effective and strategic opportunities will fund energy infrastructure improvements, energy planning, workforce training and development, and low-income weatherization, among other critical efforts. This comprehensive work will increase access to energy efficiency to help American families, businesses, and communities save money; achieve our clean energy goals; and accelerate job growth nationwide.
