Renewable Energy

Definition

Renewable energy refers to energy derived from natural resources that are replenished at a faster rate than they are consumed, such as sunlight, wind, rain, tides, waves, and geothermal heat. This type of energy is essential in addressing global challenges, as it reduces dependence on fossil fuels, minimizes environmental impact, and contributes to sustainable development by providing cleaner alternatives to meet energy demands.
