We require various energy sources to live and work. These include wind, solar and geothermal as well as biomass sources. In addition to being the primary source of electricity they are also used for transport and heating. The main issue for these energy sources is that they may cause greenhouse gas emissions when used to generate electricity. This results in the need for more sustainable energy sources.
Fossil fuels are the most well-known form of energy. They include oil, coal and natural gas. They began to form millions and millions of years ago when prehistoric animals and plants died and were covered by layers of sedimentary rock. In web link the appropriate conditions, they gradually converted to carbon-rich substances that, when burned create energy. They are not renewable as they will run out in our lifetimes or in many lifetimes.
Renewable energy sources are, however are constantly replenished. The most important renewable energy source is sunlight, which supplies heat and light. We utilize it for our homes vehicles, businesses, and homes. Wind is a different renewable energy source, which generates electricity through spinning turbines. We have been using it since the first began to harness the wind for millennia. In the end, we employ biological processes to create an ethanol (a clear alcohol that can be used as fuel) from waste and crop residues.
As a result hydropower is the most significant renewable energy source in the United States, though wind and biofuels are expected become the dominant source in the near future. Hydropower draws on nature’s hydro cycle to harness the power of fast-flowing water, which is used to generate electricity.
