Different Energy Sources

We require a variety of energy sources to live and work. Geothermal, solar, wind and biomass are some of the sources. These sources are not only an important source of electricity, but can also be used for heating and transport. The major issue with these sources of energy is that they can cause greenhouse gas emissions if they are burned to generate electricity. This results in the need for more green energy sources.

The most commonly used kind of energy is called fossil fuels, made up of coal, oil, and natural gas. They began to form millions and millions of years ago when animals and plants of the past passed away and were then buried beneath layers of sedimentary rock. In the right conditions, they were slowly esperienza consolidata dalla sala riunioni transformed into carbon-rich substances which, when burnt produce energy. The fossil fuels cannot be renewable since they will become depleted by the time we reach our age or over the course of many years.

Renewable energy sources are replenished regularly. The sun is the primary source of renewable energy, since it supplies light and heat. We utilize it for our homes as well as for businesses and automobiles. Wind is an energy source that is renewable and produces electricity through spinning turbines. Since the first time people realized how to harness wind, we have been using it for millennia. We employ biological processes to produce an ethanol (a clear, alcohol-like substance which can be used as fuel) from the waste of crops and other materials.

In the list of sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are likely to become the leading source of energy in the near future. Hydropower utilizes the natural water cycle to harness water’s rapid flow, which in turn can be used to produce electricity.
