Different energy sources provide us with the energy we require to live and work. These include wind, solar, geothermal, and biomass sources. These sources aren’t just major sources of electricity, but they can also be used to heat and transport. These energy sources can emit greenhouse gases when they are burned to generate electricity. This leads to the need for more environmentally sustainable energy sources.

The most commonly used kind of energy is fossil fuels, which consist of coal, oil, and natural gas. They began to form millions of years ago when prehistoric plants and animals died and were buried under layers of sedimentary rock. Under the right conditions the fossil fuels gradually transformed into carbon-rich substances that, when burnt generate energy. These fossil fuels are non-renewable since they will be exhausted within our lifetimes or in a number of lifetimes.

Renewable energy sources are replenished continuously. The sun is the primary source of renewable energy since it provides warmth and light. We utilize it for our homes business, cars, and homes. Wind is another renewable energy source that generates electricity by spinning turbines. Since the first people discovered how to harness the wind, we have been using it for millennia. In addition, we employ biological web link processes to make ethanol (a clear alcohol that can be used to fuel) from waste and crops.

Hydropower is by far the most important renewable energy source in America, however wind and biofuels will soon take over. Hydropower uses the natural water cycle to harness water’s swift flow, which in turn is used to generate electricity.
