Renewable energy

Definition

Renewable energy refers to energy that is generated from natural processes that are continuously replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat. This type of energy is crucial for sustainable design and green engineering because it reduces reliance on fossil fuels and minimizes environmental impact. The shift towards renewable energy is essential for mitigating climate change effects and promoting energy security while offering engineers innovative pathways to tackle environmental challenges.
