Different Energy Sources

We require a variety of energy sources to work and live. They include wind, solar, geothermal, and biomass sources. These sources are not just an important source of electricity, but they can also be used to heat or transport. They can also emit greenhouse gases when they are burned to create electricity. This is why it is necessary to find renewable energy sources that are more sustainable.

The most commonly used type of energy is the fossil fuels, made up of coal oil, natural gas. They formed millions of years ago when prehistoric plants and animals died and were buried by layers of sedimentary rock. In the right conditions these fossil fuels gradually transformed into carbon-rich substances which, when burned produce energy. These fossil fuels won’t be renewable since they will run dry in our lifetimes or in a variety of lifetimes.

Renewable energy sources, on the other hand are constantly replenished. The sun is the most important source of renewable energy, since it provides heat and light. It is used for our homes, businesses, and cars. Wind is an energy source renewable that produces electricity through spinning turbines. We have been using it since the web link first discovered how to harvest the wind for millennia. We use biological processes create the ethanol (a alcohol-like substance that is clear and transparent that can be used as fuel) from the waste of crops and other materials.

Hydropower is the largest renewable energy source in the US, but biofuels and winds will soon overtake it. Hydropower relies on nature’s cyclic water cycle to harness the power of swiftly flowing water, which is then used in turn to generate electricity.
