Renewable energy refers to energy derived from natural sources that can be replenished and are not depleted over time.
Role in Energy Diversification
Renewable energy sources such as solar, wind, hydroelectric, and geothermal have gained increased attention as we work to diversify our energy mix. The U.S. has experienced significant growth in renewable energy capacity, driven by technological advancements and supportive policies.
The share of renewable energy sources is expected to increase significantly. Technological advancements and falling costs have made renewables increasingly competitive. This shift will contribute to reduced greenhouse gas emissions, improved air quality, and enhanced energy security.=
According to the International Energy Agency, global energy demand for renewables will continue to rise in the coming decades. Oil and natural gas will continue to be needed to help meet that demand while renewables and other energy technologies mature and penetrate markets. In addition, products derived from oil and natural gas are critical components of renewable energy infrastructure like solar panels and windmills.
Common forms of renewable energy include:
-
Solar power harnesses the energy from sunlight using photovoltaic panels or concentrated solar power systems to convert sunlight into electricity or heat. Solar power is renewable and solar systems do not create any greenhouse gas emissions.
-
Wind turbines capture the kinetic energy of the wind and convert it into electricity. Wind farms are commonly installed in windy regions to generate energy. Wind power is renewable and creates no greenhouse gas emissions.
-
Biomass uses organic matter such as plants, agricultural waste, wood or algae to produce heat or generate electricity through combustion or biological processes. U.S. scientists are continuously researching and exploring the opportunity to convert biomass into biofuels that can take the place of conventional fuels like gasoline, diesel, and jet fuel. Biomass energy production is widely available and reliable but does create greenhouse gas emissions.
