Different Energy Sources
We require a variety of energy sources to live and work. Geothermal, solar, wind and biomass are some of the sources. These sources aren’t only major sources of electricity, but can also be used for heating and transport. These energy sources emit greenhouse gases when they are burned to produce electricity. This is why there is a need for more sustainable energy sources.
Fossil fuels are the most widely used form of energy. They include oil, coal and natural gas. They were created thousands of years ago when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. Then, under the right conditions, they were slowly transformed into carbon-rich substances which, when burned, generate energy. These fossil fuels won’t be renewable because they will end up being depleted in our lifetimes or in a variety of lives.
Renewable energy sources are replenished regularly. The primary renewable energy source is sunlight, which provides warmth and light. It is used for our homes, businesses, and cars. Wind is another renewable energy source that produces electricity by spinning turbines. Since the first time people realized how to harness wind, we have been using it for millennia. We also use biochemical processes to create ethanol (a clear alcohol that can be used to fuel) from crops and waste.
Hydropower is by far the most important renewable energy source in America, but wind and biofuels will soon overtake it. Hydropower utilizes the natural water cycle to harness the power of water’s rapid flow, which in turn produces electricity.
