The transition to a clean energy economy will enhance the lives of all Americans.
Clean energy is important because it has the power to enhance economic growth, support energy independence, and improve the health and well-being of the American people. The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) is committed to leading the nation’s transition to a clean energy economy for these reasons.
What Is Clean Energy?
Renewable energy resources provide an affordable, reliable, and sustainable U.S. power supply—while also reducing the country’s greenhouse gas emissions. We can harness abundant domestic resources including wind energy, solar energy, bioenergy, geothermal energy, hydropower, and marine energy to reduce our reliance on fossil fuels. About 20% of all U.S. electricity now comes from renewable energy sources with 60% from fossil fuels like coal, petroleum, and natural gas, and the remainder from nuclear energy.
Why Do We Need Clean Energy?
Renewable power is not only cost-competitive; it’s also the most cost-effective source of energy in many situations, depending on the location and season. Still, we have more work to do both on the technologies themselves and on our nation’s electric system as a whole to achieve the U.S. climate goal of 100% carbon-pollution-free electricity by 2035.
EERE’s job is to give Americans access to the energy resources they want at a price they can afford with the infrastructure they can count on.
