Renewable energy refers to energy derived from natural sources that are replenished on a human timescale, such as sunlight, wind, rain, tides, geothermal heat, and biomass. Unlike fossil fuels, which are finite and contribute to environmental degradation, renewable energy sources are sustainable and have minimal impact on the environment.

Key technologies in renewable energy include solar panels, wind turbines, hydroelectric dams, geothermal plants, and bioenergy systems. These technologies play a critical role in reducing greenhouse gas emissions, mitigating climate change, and promoting energy security.

Renewable energy is widely regarded as a cornerstone of the global transition to a cleaner, greener, and more sustainable future. It offers opportunities for innovation, economic growth, and job creation while addressing critical environmental challenges.
