We require a variety of energy sources to work and live. Solar, wind, geothermal and biomass are a few of the sources. These sources aren’t just the primary source of electricity, but they can also be used to heat and transport. They can also emit greenhouse gases when burned to create electricity. This means that there is a need for renewable energy sources that are more sustainable.
The most common kind of energy is fossil fuels, which consist of coal oil, natural gas. They formed https://leonardogiombini.it/2021/07/05/generated-post millions of years ago when prehistoric animals and plants died and were buried by layers of sedimentary rock. In the right conditions, they gradually converted to carbon-rich substances which, when burnt, generate energy. These fossil fuels are not renewable since they will exhaust in our lifetimes or in many lifetimes.
Renewable energy sources however are constantly replenished. The sun is the largest source of renewable energy, because it is a source of warmth and light. We use it to power our homes and businesses as well to drive our vehicles. Wind is an energy source renewable that generates electricity through spinning turbines. We have used it since humans first began to harness the wind for millennia. In addition, we employ biochemical processes to create ethanol (a clear alcohol that can be used to create fuel) from waste and crop residues.
Among these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are expected be the next to take over. Hydropower uses the natural water cycle to harness the water’s rapid flow, which in turn can be used to produce electricity.
