We require a variety of energy sources to work and live. These include solar, wind and geothermal as well as biomass sources. These sources are not just a major source for electricity, but they can also be used to heat and transport. These energy sources emit greenhouse gases when they are burned to produce electricity. This means that there is a need for more sustainable energy sources.
The most common kind of energy is fossil fuels, which consist of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants died and were buried under layers of sedimentary rocks. Then, under the right conditions, they were gradually converted to carbon-rich substances that, when burned produce energy. These fossil fuels will not be renewable as they will become depleted by the time we reach our age, or in many lifetimes.
Renewable energy sources are constantly replenished. The sun is the most important source of renewable energy because it is a source of heat and light. It is used for our homes business, cars, and homes. Wind is renewable energy source that produces electricity through spinning turbines. Since the first time people realized how to harness the wind, we have been using it for millennia. In addition, we employ biological processes to create ethanol (a clear alcohol that can be used to fuel) from waste and crop residues.
Hydropower is the most important renewable energy source in the US, but biofuels and winds will soon surpass it. Hydropower utilizes the natural water cycle to harness water’s rapid flow, which can description be used to produce electricity.
