Different Energy Sources
We require different sources of energy to work and live. Solar, wind, geothermal and biomass are a few of the sources. In addition to being a major source of electricity, these sources are also used for transportation and heating. These energy sources emit greenhouse gases when they are burned to generate electricity. This creates a need for more environmentally sustainable energy sources.
Fossil fuels are the most widely used form of energy. They comprise oil, coal and natural gas. They began to form millions and millions of years ago when prehistoric plants and animals died and were covered by layers of sedimentary rock. When the proper conditions, they gradually converted to carbon-rich substances which, when burnt create energy. The fossil fuels cannot be renewable, as they’ll end up being depleted in our lifetimes or over the course of many years.
Renewable energy sources are, however are constantly replenished. The sun is the main source of renewable energy, since it provides warmth and light. We utilize it for our homes business, cars, and homes. Wind is an energy source that is renewable and produces electricity by spinning turbines. Since the first time people realized how to harness wind we have been utilizing it for millennia. We use biological processes to create the ethanol (a clear, alcohol-like substance which can be used as fuel) from food waste and crops.
Hydropower is by far the most important renewable energy source in the United States, but biofuels and winds will soon overtake it. Hydropower makes use of the natural water cycle to harness the power of water’s rapid flow, which can be used to produce electricity.
