We require various energy sources to work and live. These include solar, wind and geothermal as well as biomass sources. These sources aren’t only major sources of electricity, but also can be used for heating and transport. The main challenge with these sources of energy is that they can cause greenhouse gas emissions when burned to produce electricity. This is why there is a need for more environmentally sustainable energy sources.
Fossil fuels are the most well-known type of energy. They include oil, coal, and natural gas. They began to form millions of years ago when animals and plants of the past passed away and were then buried beneath layers of sedimentary rock. Under the right conditions these https://leonardogiombini.it/2021/07/13/generated-post-2 fossil fuels gradually transformed into carbon-rich substances that, when burned produce energy. The fossil fuels cannot be renewable as they will become depleted by the time we reach our age or over the course of many lives.
Renewable energy sources are constantly replenished. The sun is the main source of renewable energy, because it is a source of light and heat. We use it for our homes vehicles, businesses, and homes. Wind is a different renewable energy source that generates electricity by spinning turbines. We have been using it since people first began to harness the wind for millennia. In the end, we employ biological processes to make alcohol (a clear alcohol that can be used as fuel) from waste and crop residues.
Of all these sources, hydropower is the largest renewable energy source in the United States, though wind and biofuels are expected be the next to take over. Hydropower uses the natural water cycle to harness water’s rapid flow, which is used to generate electricity.
