Different Energy Sources

We require a variety of energy sources to work and live. Solar, wind, geothermal and biomass are a few of the sources. In addition to being a major source of electricity they can also be used to transport and heat. The biggest issue with these sources of energy is that they can cause greenhouse gas emissions when used to produce electricity. This is why it is necessary to find greener sources of energy.

Fossil fuels are the most widely used form of energy. They include oil, coal and natural gas. They began to form millions and millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. Under the right conditions, these fossil fuels were gradually transformed into carbon-rich substances which, when burned, produce energy. They are not renewable since they will be exhausted in our lifetimes, or in many lifetimes.

Renewable energy sources, on the other hand, are continually replenished. The sun is the main source of renewable energy as it provides both heat and light. It is used to power our homes and businesses as well as to drive vehicles. Wind is renewable energy source that produces electricity by spinning turbines. Since the first people discovered how to harness the wind in the past, we have been using it for millennia. We use biological https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre/ processes create alcohol (a clear, alcohol-like substance that can be used as fuel) from the waste of crops and other materials.

Hydropower is the main renewable energy source in America, however biofuels and wind are likely to surpass it. Hydropower utilizes the natural water cycle to harness water’s swift flow, which is used to generate electricity.
