Renewable energy refers to energy derived from natural sources that are replenished at a faster rate than they are consumed. This includes sources like solar, wind, and hydropower, which are essential for reducing our reliance on fossil fuels and combating climate change. The use of renewable energy is growing rapidly as technology advances and awareness of environmental issues increases. By harnessing these sustainable resources, we can create a cleaner, more sustainable future for generations to come, while also promoting energy independence and economic growth.
