Renewable power sources

Definition

Renewable power sources refer to energy sources that are replenished naturally over short periods of time, such as sunlight, wind, rain, tides, waves, and geothermal heat. These sources contrast with fossil fuels, which are finite and contribute to environmental degradation. The importance of renewable power lies in its potential to provide sustainable energy solutions that reduce greenhouse gas emissions and promote environmental stewardship.
