We require different sources of energy to live and work. Geothermal, solar, wind and biomass are a few of the sources. These sources aren’t only the primary source of electricity, but they can also be used to heat or transport. These energy sources can emit greenhouse gases when they are burned to produce electricity. This results in the need for more environmentally sustainable energy sources.
The most widely used type of energy is fossil fuels, which consist of coal oil, natural gas. They were formed millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. After that, under the appropriate conditions, they gradually transformed into carbon-rich materials that, when burned, generate energy. They are not renewable as they will run out within our lifetimes or in many lifetimes.
Renewable energy sources, on the other hand, are continually replenished. The sun is the primary source of renewable energy because it is a source of warmth and light. We use it to power our homes and businesses as well to drive our cars. Wind is an energy source that is renewable and generates electricity by spinning turbines. We have been using it since we first discovered how to harvest the wind for millennia. We use biological processes produce alcohol (a clear, alcohol-like substance that can be used to make fuel) from waste and crops.
Of all these sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are likely to become the dominant source in the near future. Hydropower relies on nature’s cyclic water cycle to harness the power of flowing water, which is then used to generate electricity.
