Different Energy Sources

We need different energy sources to live and work. They include wind, solar and geothermal as well as biomass sources. These sources aren’t just a major source for electricity, but they can also be used to heat or transport. They can also emit greenhouse gases when burned to produce electricity. This is why there is a need for more green energy sources.

Fossil fuels are the most widely used type of energy. They include oil, coal and natural gas. They were formed millions of years ago when animals and plants of the past passed away and were then buried beneath layers of sedimentary rock. When the appropriate conditions, they gradually transformed into carbon-rich compounds which, when burned produce energy. They are not renewable as they will run out in our lifetimes or even in many lives.

Renewable energy sources however, are continually replenished. The most important renewable energy source is sunlight, which produces light and heat. We use it for our homes as well as for businesses and automobiles. Wind is another renewable energy source, which produces electricity by spinning turbines. We have been using it since the first discovered how to harvest the wind for millennia. We also use biological processes to create an ethanol (a clear alcohol that can be used to create fuel) from crops and waste.

As a result, hydropower is the find more information largest renewable energy source in the United States, though wind and biofuels are predicted to become the leading source of energy in the near future. Hydropower makes use of the natural water cycle to harness the water’s rapid flow, which can be used to produce electricity.
