We need different energy sources to live and work. Solar, wind, geothermal and biomass are some of the sources. In addition to being the primary source of electricity they can also be used for transport and heat. The main challenge for these energy sources is that they could cause greenhouse gas emissions when they are burned to produce electricity. This results in the need for more green energy sources.

The most commonly used kind of energy is called fossil fuels, made up of coal oil, natural gas. They were created millions of year ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. After that, under the right conditions, they were gradually transformed into carbon-rich compounds which, when burnt create energy. These fossil fuels cannot be recycled as they will run out in our lifetimes or even in many lifetimes.

Renewable energy sources are constantly replenished. The sun is the main source of renewable energy, since it supplies warmth and light. We utilize it for our homes, businesses, and cars. Wind is an energy source that is renewable and generates electricity by spinning turbines. We have been using it since the first discovered how to harvest the wind for millennia. We employ biological processes to produce ethanol (a alcohol-like substance that is clear and transparent which can be used as fuel) from food waste and crops.

Hydropower is by far the most important renewable energy source in the United States, but biofuels and wind are likely to overtake it. Hydropower makes use of the natural water cycle to harness water’s rapid flow, which https://leonardogiombini.it/2021/11/29/top-vdr-providers-which-come-with-247-support-for-all-deal-makers in turn is used to generate electricity.
