Different energy sources supply us with the energy we require to live and work. They include wind, solar, geothermal, and biomass sources. In addition to being a major source of electricity, these sources can also be used to transport and heating. The major issue for these energy sources is that they can cause greenhouse gas emissions when used to produce electricity. This results in the need for more environmentally sustainable energy sources.
The most common kind of energy is called fossil fuels, made up of coal oil, natural gas. They were formed millions of year ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. When the right conditions, they were gradually transformed into carbon-rich compounds that, when ignited create energy. These fossil fuels will not be renewable since they will run dry in our lifetimes or over the course of many lives.
Renewable energy sources, on the other hand are constantly replenished. The sun is the main source of renewable energy, as it provides both warmth and light. We use it to power our homes and businesses, as well as to drive cars. Wind is a different renewable energy source that produces electricity by spinning turbines. We have been using it since people first discovered how to harvest the wind for millennia. We use biological processes to produce alcohol (a alcohol-like substance that is clear and transparent which can be used as fuel) from food 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 draws on nature’s hydro cycle to harness the power of swiftly flowing water, which is used for electricity generation.
