Different Energy Sources

Different energy sources provide us with the power we require to live and work. Solar, wind, geothermal and biomass are just a few of the sources. These sources are not only major sources of electricity, but they can also be used to heat or transport. The biggest issue with these energy sources is that they may cause greenhouse gas emissions if they are burned to produce electricity. This means that there is a need for more sustainable energy sources.

The most popular kind of energy is called fossil fuels, which include coal oil, natural gas. They began to form millions of years ago when animals and plants of the past died and were covered by layers of sedimentary rock. When the right conditions, they were gradually converted to carbon-rich substances that, when burned create energy. They are not renewable because they will run out in our lifetimes or in many lives.

Renewable energy sources are continuously replenished. The sun is the primary source of renewable energy as it provides both light and heat. We use it to power our homes and businesses, as well as to Related Site drive cars. Wind is an energy source that is renewable and generates electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. Finally, we use biological processes to create alcohol (a clear alcohol that can be used to fuel) from waste and crop residues.

Hydropower is the largest renewable energy source in America, but wind and biofuels will soon overtake it. Hydropower relies on nature’s water cycle to harness the power of rapid-flowing water, which is used in turn to generate electricity.
