: Taps into thermal energy stored under the Earth's crust for both heating and electricity generation.
: Photovoltaic cells capture sunlight and convert it directly into electricity, or thermal systems use the sun’s heat for water and space heating. GREEN ENERGY
: Turbines use the kinetic energy of air movement to generate electricity. This is often considered the "cleanest" source as it requires minimal external inputs like water. : Taps into thermal energy stored under the
Green energy is any form of energy generated from natural resources—such as sunlight, wind, or water—that provides the highest environmental benefit by producing little to no greenhouse gas emissions. Unlike fossil fuels, which are finite and take millions of years to form, green energy sources are naturally and perpetually replenished. This is often considered the "cleanest" source as
: Captures energy from flowing water in rivers, waterfalls, or dams. While renewable, only small-scale or low-impact plants are strictly considered "green" due to the potential environmental disruption caused by large dams.
The primary sources of green energy are distinguished by how they harness natural phenomena:
