Different energy sources supply us with the energy we require to live and work. These include wind, solar geothermal, biomass, and geothermal sources. These sources aren’t just an important source of electricity, but can also be used to heat and transport. These energy sources emit greenhouse gases when burned to generate electricity. This is why it is necessary to find greener sources of energy.
The most popular type of energy is the fossil fuels, which consist of coal, oil, and natural gas. They were created thousands of years ago, when prehistoric animals and plants died and were buried under layers of sedimentary rocks. If the conditions were right the fossil fuels gradually transformed into carbon-rich compounds that, when burned generate energy. The fossil fuels cannot be renewable since they will end up being depleted in our lifetimes or over the course of many lifetimes.
Renewable energy sources On the other hand, are continually replenished. The primary renewable energy source is sunlight, which gives heat and light. We use it for our homes as well as for businesses and automobiles. Wind is another renewable energy source, which generates electricity through spinning turbines. We have been using it since the first began to harness the wind for millennia. We employ biological processes to produce ethanol (a alcohol-like substance that is clear and transparent that can be used for fuel) from crops and waste.
Among these sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are expected to take the lead soon. Hydropower relies on nature’s water cycle to harness the power of swiftly flowing water, which is used in turn to generate electricity.
