Different energy sources supply us with the energy we need to live and work. Geothermal, solar, wind and biomass are among the sources. In addition to being an important source of electricity, these sources are also used for transportation and heating. The main issue with these energy sources is that they can cause greenhouse gas emissions if they are burned to generate electricity. This is why there is a need for more sustainable energy sources.

The most common kind of energy is called fossil fuels, made up of coal, oil, and natural gas. They were formed thousands of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. When the right conditions, they were gradually transformed into carbon-rich materials which, when burned produce energy. These fossil fuels won’t be renewable, as they’ll end up being depleted in https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure/ our lifetimes or in a variety of years.

Renewable energy sources On the other hand are continuously replenished. The sun is the primary source of renewable energy, since it supplies warmth and light. It is used to power our homes and businesses as well to drive vehicles. Wind is another renewable energy source, which produces electricity by spinning turbines. Since the first people discovered how to harness the wind we have been utilizing it for millennia. Finally, we use biochemical processes to create alcohol (a clear alcohol that can be used to create fuel) from waste and crop residues.

As a result hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected to take the lead soon. Hydropower makes use of the natural water cycle to harness the power of water’s rapid flow, which in turn is used to produce electricity.
