Different energy sources supply us with the energy we need to live and work. These include solar, wind geothermal, biomass, as well as geothermal sources. In addition to being a major source of electricity they are also used for transport and heating. The major issue for these energy sources is that they can cause greenhouse gas emissions when used to produce electricity. This means that there is a need for greener sources of energy.
Fossil fuels are the most widely used form of energy. They include oil, coal, and natural gas. They began to form millions and millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. When the right conditions, they gradually transformed into carbon-rich materials which, when burnt create energy. These fossil fuels are not renewable since they will exhaust in our lifetimes or in many lives.
Renewable energy sources are, however, are continually replenished. The most important renewable energy source is sunlight, which supplies light and heat. We use it to power our homes vehicles, businesses, and homes. Wind is a different renewable energy source, which generates electricity by spinning turbines. We have been using it since the first discovered how to harvest the wind for millennia. In addition, we employ biological processes to produce the ethanol (a clear alcohol that can be used as a fuel) from waste and crops.
Among these sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are expected to become the leading source of energy in the near future. Hydropower relies on nature’s water cycle to harness the power of flowing water, which is then used to generate electricity.
