Different Energy Sources

Diverse energy sources provide us with the energy we require to live and work. These include wind, solar, geothermal, and biomass sources. These sources are not only the primary source of electricity, but they can also be used for heating and transport. The main issue for these energy sources is that they may cause greenhouse gas emissions when used to produce electricity. This is why it is necessary to find more sustainable energy sources.

The most commonly used kind of energy is called fossil fuels, which consist of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. In the proper conditions, they gradually transformed into carbon-rich materials that, when ignited produce energy. They are not renewable because they will run out in our lifetimes or in a number of lifetimes.

Renewable energy sources are constantly replenished. The sun is the main source of renewable energy, since it supplies warmth and light. We use it to power our homes as well as for businesses and automobiles. Wind is a different renewable energy source that generates electricity through spinning turbines. Since the first people discovered how to harness wind in the past, we have been using it for millennia. Finally, we use biological processes to make alcohol (a clear alcohol that can be used as fuel) from waste and crop residues.

Hydropower is the most important renewable energy source in America, however wind and biofuels will soon surpass it. Hydropower utilizes the natural water cycle to harness water’s swift flow, which in turn is used to produce electricity.
