Renewable energy refers to energy sources that are replenished naturally and can be used repeatedly. Unlike non-renewable sources, such as coal and oil, renewable energy sources are not depleted by use. The most common types of renewable energy include solar, wind, hydro, geothermal, and bioenergy. Solar energy is produced by converting the sun's energy into electricity using solar panels. Wind energy is generated by the movement of wind turbines. Hydro energy is produced by the movement of water, such as in a hydroelectric dam. Geothermal energy is produced by harnessing the heat generated by the Earth's core. Bioenergy is produced by converting organic matter, such as plants, into energy. Renewable energy is seen as a crucial component in the fight against climate change, as it produces significantly fewer greenhouse gas emissions than non-renewable sources. Additionally, renewable energy is becoming increasingly competitive in terms of cost, making it a more attractive o...
