Renewable energy

Definition

Renewable energy refers to energy derived from natural processes that are continually replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat. This type of energy is crucial for reducing human impact on the environment, as it offers a sustainable alternative to fossil fuels, which contribute to climate change and global warming. Transitioning to renewable energy sources is vital for achieving energy security and promoting sustainable development across regions.
