Different Energy Sources

We require a variety of energy sources to work and live. Geothermal, solar, wind and biomass are some of the sources. In addition to being a major source of electricity they are also used for heat and transport. The biggest issue for these energy sources is that they could cause greenhouse gas emissions when used to produce electricity. This creates a need for more sustainable energy sources.

The most popular kind of energy is called fossil fuels, comprised 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. In the right conditions the fossil fuels gradually transformed into carbon-rich substances which, when burned create energy. These fossil fuels will not be renewable technical-mechanic areas in the civil engineering field as they will run dry in our lifetimes, or in many years.

Renewable energy sources are continuously replenished. The primary renewable energy source is sunlight, which produces light and heat. It is used for our homes, businesses, and cars. Wind is an energy source that is renewable and generates electricity by spinning turbines. Since the first people discovered how to harness the wind we have been utilizing it for millennia. We employ biological processes to create alcohol (a alcohol-like substance that is clear and transparent which can be used as fuel) from the waste of crops and other materials.

In the list of sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are likely to take the lead soon. Hydropower is based on nature’s water cycle to harness the power of flowing water, which is used for electricity generation.
