Different energy sources supply us with the power we need to live and work. Geothermal, solar, wind and biomass are some of the sources. In addition to being a major source of electricity, these sources are also used for heat and transport. These energy sources produce greenhouse gases when they are used to generate electricity. This creates the need for more sustainable sources of energy.
Fossil fuels are the most well-known form of energy. They include oil, coal, and natural gas. They were formed thousands of years ago, when prehistoric animals and plants died and were then buried under layers of sedimentary rocks. If the conditions were right they were slowly transformed into carbon-rich materials that, when burned produce energy. These fossil fuels won’t be renewable because they will end up being depleted in our lifetimes or in a variety of lifetimes.
Renewable energy sources however, are continually replenished. The sun is the largest source of renewable energy, since it supplies heat and light. We use it to power our homes and businesses as well as https://leonardogiombini.it/2021/07/05/generated-post/ to drive vehicles. Wind is another renewable energy source that generates electricity by spinning turbines. We have used it since humans first began to harness the wind for millennia. In addition, we employ biological processes to create ethanol (a clear alcohol that can be used as fuel) from waste and crops.
Of all these sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are expected to be the next to take over. Hydropower makes use of the natural water cycle to harness the power of water’s rapid flow, which is used to produce electricity.
