Different Energy Sources

We require different sources of energy to work and live. They include wind, solar geothermal, biomass, as well as geothermal sources. In addition to being a major source of electricity they can also be used to heat and transport. The major issue for these energy sources is that they can create greenhouse gas emissions when 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 https://leonardogiombini.it/2019/02/14/interessante-articolo-sui-biocarburanti years ago when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. When the right conditions, they were gradually transformed into carbon-rich materials which, when burned produce energy. These fossil fuels will not be renewable, as they’ll end up being depleted in our lifetimes or in a number of years.

Renewable energy sources however, are continually replenished. The sun is the primary source of renewable energy because it is a source of warmth and light. It is used to power our homes and businesses as well as to drive our vehicles. Wind is a different renewable energy source that generates electricity through spinning turbines. We have been using it since we first discovered how to harvest the wind for millennia. We also use biochemical processes to create ethanol (a clear alcohol that can be used as fuel) from waste and crops.

As a result hydropower is the biggest renewable energy source in the United States, though wind and biofuels are likely to take the lead soon. Hydropower uses the natural water cycle to harness the water’s rapid flow, which in turn can be used to produce electricity.
