Different energy sources provide us with the energy we need to live and work. These include wind, solar and geothermal as well as biomass sources. In addition to being an important source of electricity they are also used for heat and transport. The main issue for these energy sources is that they could cause greenhouse gas emissions when burned to produce electricity. This creates the need for more sustainable energy sources.
Fossil fuels are the most common form of energy. They include oil, coal and natural gas. They formed millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. If the conditions were right they were gradually transformed into carbon-rich compounds which, when ignited produce energy. These fossil fuels won’t be renewable since they will become depleted by the time we reach our age, or in many years.
Renewable energy sources are replenished continuously. The sun is the largest source of renewable energy, since it supplies light and heat. It is used for our homes, businesses, and cars. Wind is a different renewable energy source that generates electricity through spinning turbines. We have used it since humans first began to harness the wind for millennia. In the end, we employ biological processes to create ethanol (a clear alcohol that can be used to create fuel) from waste and crops.
Hydropower is the largest renewable energy source in the United States, but biofuels and wind are likely to surpass it. Hydropower uses the natural water cycle to harness water’s swift flow, which is used to produce electricity.
