Additionally, renewable energy sources are usually much more environmentally friendly than fossil fuels. Overall, they release very few chemicals, like carbon dioxide, that can harm the environment. Most of this energy comes from fossil fuels, such as coal, oil, and natural gas.

Fossil fuels also contribute greatly to global climate change by releasing carbon dioxide into the air when they are burned.
