Renewable energy

Definition

Renewable energy refers to energy derived from natural sources that are replenished at a faster rate than they are consumed, such as solar, wind, hydro, and geothermal power. This type of energy plays a critical role in promoting sustainability by reducing reliance on fossil fuels, thereby contributing positively to economic growth, social equity, and environmental preservation.
