Different Energy Sources

Different energy sources supply us with the energy we need to live and work. Geothermal, solar, wind and biomass are a few of the sources. In addition to being a major source of electricity they can also be used to transport and heat. The main issue with these sources of energy is that they could cause greenhouse gas emissions when used to generate electricity. This is why there is a need for more environmentally sustainable energy sources.
Fossil fuels are the most widely used type of energy. They include coal, oil and natural gas. They began to form millions of years ago when prehistoric animals and plants died and were buried under layers of sedimentary rock. If the conditions were right the fossil fuels slowly transformed into carbon-rich materials that, when burned produce energy. They are not renewable since they will exhaust in our lifetimes, or in a number of lifetimes.
Renewable energy sources On the other hand are constantly replenished. The sun is the most important source of renewable energy since it supplies warmth and light. We utilize it for our homes vehicles, businesses, and homes. Wind is a renewable energy source that produces electricity through spinning turbines. Since the first time people realized how to harness wind and harness it, we have been using it for millennia. In the end, we employ biological processes to produce the ethanol (a clear alcohol that can be used to fuel) from waste and crops.
In the list of sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are predicted to become the leading source of energy in the near future. Hydropower utilizes the natural water cycle to harness the water’s rapid flow, which is used to produce electricity.
