Different Energy Sources
Different energy sources provide us with the energy we require to live and work. These include wind, solar geothermal, biomass, as well as geothermal sources. These sources are not just a major source for electricity, but can also be used to heat and transport. The biggest issue with these sources of energy is that they can create greenhouse gas emissions when they are burned to generate electricity. This results in the need for more sustainable energy sources.
The most popular type of energy is the fossil fuels, comprised of coal, oil, and natural gas. They were created thousands of years ago, when prehistoric animals and plants died and were buried beneath layers of sedimentary rocks. When the conditions were right these fossil fuels gradually transformed into carbon-rich substances that, when burned produce energy. These fossil fuels are not renewable as they will run out within our lifetimes or in many lifetimes.
Renewable energy sources are, however, are continually replenished. The sun is the main source of renewable energy since it provides warmth and light. It is used to power our homes and businesses as well as to drive our vehicles. Wind is an energy source renewable that produces electricity by spinning turbines. We have been https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche/ using it since people first discovered how to harvest the wind for millennia. We employ biological processes to produce the ethanol (a clear, alcohol-like substance that can be used as fuel) from food waste and crops.
Among these sources hydropower is the most significant renewable energy source in the United States, though wind and biofuels are likely 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.
