What is renewable energy?
Renewable energy is energy produced from sources that do not run out or can be replenished within a human's lifetime. Renewable energy sources include the sun and wind; both do not run out, so we don’t have to worry about using them up. Traditional energy sources come from fossil fuels that are extracted from the Earth, such as natural gas or coal. When we burn these materials to generate energy at power plants, they release toxic air pollution and greenhouse gases. By switching to renewable energy, we can lower the amount of pollution in our environment and decrease the use of fossil fuels.
