In three to five sentences, list examples of renewable and nonrenewable energy sources. Then compare and contrast the energy sources in terms of environmental impact.

Renewable energy sources include solar, wind, hydro, geothermal, and biomass. Nonrenewable energy sources include coal, oil, and natural gas. Renewable energy sources have little to no environmental impact, as they produce no pollutants or emissions. In contrast, nonrenewable energy sources have a significant environmental impact, leading to air and water pollution, as well as contributing to climate change.
