READ MORERenewable resources include biomass energy (such as ethanol ), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants). Biomass can be used as a source of energy because this
READ MOREWind energy was the source of about 10.2% of total U.S. utility-scale electricity generation and accounted for 47.6% of electricity generation from renewable sources in 2022. Wind turbines convert wind energy into electricity. Hydropower plants produced about 6.2% of total U.S. utility-scale electricity generation and accounted for
READ MOREThe term "renewable" encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully "renewable" resources are not depleted by human use, whereas "semi-renewable" resources must be properly managed to ensure long-term
