We require different sources of energy to work and live. These include wind, solar and geothermal as well as biomass sources. These sources aren’t only major sources of electricity, but also can be used to heat and transport. They can also emit greenhouse gases when they are burned to produce electricity. This leads to the need for more sustainable energy sources.

Fossil fuels are the most well-known type of energy. They include oil, coal, and natural gas. They began to form millions of years ago when prehistoric animals and plants died and were covered by layers of sedimentary https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili rock. In the right conditions, these fossil fuels were gradually transformed into carbon-rich substances that, when burned, produce energy. These fossil fuels will not be renewable because they will end up being depleted in our lifetimes or over the course of many years.

Renewable energy sources are constantly replenished. The sun is the main source of renewable energy, since it provides heat and light. We use 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 in the past, we have been using it for millennia. We employ biological processes to create alcohol (a alcohol-like substance that is clear and transparent that can be used for fuel) from food waste and crops.

In the list of sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected become the dominant source in the near future. Hydropower utilizes the natural water cycle to harness the power of water’s rapid flow, which produces electricity.
