We require different sources of energy to work and live. Solar, wind, geothermal and biomass are some of the sources. In addition to being a major source of electricity they can also be used for transport and heat. These energy sources produce greenhouse gases when burned to create electricity. This leads to the need for more green energy sources.
The most commonly used type of energy is fossil fuels, which consist of coal, oil, and natural gas. They were created millions of year ago when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. If the conditions were right these fossil fuels gradually transformed into carbon-rich substances which, when burned generate energy. The fossil fuels cannot be renewable because they will run dry in our lifetimes or in a variety of years.
Renewable energy sources On the other hand are continuously replenished. The most important renewable energy source is sunlight, which provides light and heat. We utilize it for our homes business, cars, and homes. Wind is a different renewable energy source that generates electricity by spinning turbines. Since the first time people realized how to harness the wind, we have been using it for millennia. We also use biochemical processes to create alcohol (a clear alcohol that can be used to create fuel) from crops and waste.
Hydropower is the largest renewable energy source in the United States, but wind and biofuels will soon take over. Hydropower makes use of the natural water cycle to harness the water’s rapid flow, which in turn is used to generate electricity.
