Different energy sources provide us with the energy we require to live and work. These include solar, wind geothermal, biomass, as well as geothermal sources. These sources aren’t only a major source for electricity, but can also be used to heat and transport. They can also emit greenhouse gases when burned to generate electricity. This means that there is a need for more sustainable energy sources.
Fossil fuels are the most widely used form of energy. They include coal, oil and natural gas. They were formed millions of years ago when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. In the right conditions, they were gradually transformed into carbon-rich compounds which, when burned, generate energy. These fossil fuels will not be renewable, as they’ll be depleted in our lifetimes, or in many lives.
Renewable energy sources are, however are continuously replenished. The primary renewable energy source is sunlight, which gives warmth and light. It is used to power our homes and businesses as well https://leonardogiombini.it/2018/10/19/i-vantaggi-delle-centrali-energetiche/ to drive vehicles. Wind is an energy source that is renewable and generates electricity by spinning turbines. We have been using it since people first began to harness the wind for millennia. Finally, we use biochemical processes to create ethanol (a clear alcohol that can be used to create fuel) from crops and waste.
As a result, hydropower is the largest renewable energy source in the United States, though wind and biofuels are expected to become the dominant source in the near future. Hydropower uses the natural water cycle to harness the water’s rapid flow, which is used to generate electricity.
