We require a variety of energy sources to live and work. They include wind, solar, geothermal, and biomass sources. These sources are not just an important source of electricity, but can also be used to heat or transport. They can also emit greenhouse gases when they are burned to generate electricity. This results in the need for more environmentally sustainable energy sources.
Fossil fuels are the most popular type of energy. They include oil, coal and natural gas. They formed millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. When the right conditions, they were slowly transformed into carbon-rich substances which, when burned, generate energy. These fossil fuels are not renewable because they will run out in our lifetimes or even in many lives.
Renewable energy sources On the other hand are constantly replenished. The sun is the most important source of https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ renewable energy since it supplies warmth and light. We use it to power our homes business, cars, and homes. Wind is another renewable energy source that generates electricity through spinning turbines. We have used it since humans first discovered how to harvest the wind for millennia. We use biological processes to create an ethanol (a clear, alcohol-like substance that can be used for fuel) from waste and crops.
As a result hydropower is the biggest renewable energy source in the United States, though wind and biofuels are likely to become the leading source of energy in the near future. Hydropower draws on nature’s hydro cycle to harness the power of rapid-flowing water, which is then used for electricity generation.
