A clean energy revolution is taking place across America, underscored by the steady expansion of the U.S. renewable energy sector.
The clean energy industry generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for the countries that invent, manufacture and export clean energy technologies.
Responsible development of all of America’s rich energy resources -- including solar, wind, water, geothermal, bioenergy & nuclear -- will help ensure America’s continued leadership in clean energy. Moving forward, the Energy Department will continue to drive strategic investments in the transition to a cleaner, domestic and more secure energy future.
Geothermal energy is heat energy from the earth. Learn about the Energy Department's investments in harnessing this important domestic heat source.
Fuel cells offer a highly efficient and fuelflexible technology that cleanly produces power and heat with low or zero emissions.
