renewable energy sources
Renewable Energy Renewable energy sources are derived from natural processes that are replenished constantly. Their main functions include generating electricity, providing heat, and fueling transportation, all while reducing greenhouse gas emissions. Technology at workVarying from type to type, the features of renewable energy vary greatly. For example, solar energy takes sunshinetriggers photovoltaic cells to change into electricity. Then wind-driven generators harness that force of nature and make it usable in an electrically driven machine. In the case of hydroelectric power, water flowing through turbines spins generators which makes electricity. Geothermal energy is produced by tapping the Earth's internal heat and it is both clean and sustainable. Bioenergy comes from converting organic matter into energy. Renewable sources are, in general, applied in residential, commercial, and industrial settings for a green approach to meet our energy needs.
