We require a variety of energy sources to work and live. Solar, wind, geothermal and biomass are among the sources. These sources aren’t only an important source of electricity, but they can also be used for heating and transport. The major issue with these energy sources is that they can create greenhouse gas emissions if they are burned to generate electricity. This creates the need for more sustainable sources of energy.

The most common kind of energy is called fossil fuels, which consist of coal oil, natural gas. They began to form millions of years ago when prehistoric animals and plants passed away and were then buried beneath layers of sedimentary rock. When the conditions were right these fossil fuels gradually transformed into carbon-rich compounds which, when burned produce energy. These fossil fuels cannot be recycled since they will be exhausted within our lifetimes or in many lifetimes.

Renewable energy sources however, are continually replenished. The most important renewable energy source is sunlight, which gives heat and light. We use it for our homes vehicles, businesses, and homes. 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. Finally, we use biological processes to produce alcohol (a clear alcohol that can be used to create fuel) from waste and crops.

In the list of sources hydropower is the biggest renewable energy source in the United States, though wind and biofuels are expected to become the leading source of esperienza consolidata dalla sala riunioni energy in the near future. Hydropower is a natural cycle to harness the water’s rapid flow, which is used to generate electricity.
