Renewable energy

Definition

Renewable energy is energy generated from natural resources that are replenished constantly, such as sunlight, wind, rain, tides, waves, and geothermal heat. This type of energy is vital for reducing greenhouse gas emissions and combating climate change, as it offers sustainable alternatives to fossil fuels. By harnessing these resources, renewable energy helps to mitigate the adverse effects of global climate change and contributes to a cleaner, healthier environment.
