We require a variety of energy sources to live and work. These include wind, solar and geothermal as well as biomass sources. These sources aren’t only major sources of electricity, but can also be used to heat and transport. The main issue with these energy sources is that they can cause greenhouse gas emissions when burned to produce electricity. This is why there is a need for more green energy sources.
Fossil fuels are the most popular form of energy. They comprise oil, coal and natural gas. They were formed thousands of years ago, when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. After that, under the proper conditions, they gradually transformed into carbon-rich materials which, when burned, generate energy. The fossil fuels cannot be renewable, as they’ll end up being depleted in our lifetimes or in a variety of years.
Renewable energy sources are replenished continuously. The sun is the most important source of renewable energy since it provides heat and light. We use it to power our homes, businesses, and cars. Wind is another renewable energy source that generates electricity through spinning turbines. Since the first people discovered how to harness wind and harness it, we have been using it for millennia. We employ biological processes to create ethanol (a alcohol-like substance that is clear and transparent that can be used for fuel) from food waste and crops.
Hydropower is the most important renewable energy source in the United States, but biofuels and winds will soon take over. Hydropower is a natural cycle to harness water’s swift flow, which produces electricity.
