We require different sources of energy to live and work. Solar, wind, geothermal and biomass are a few of the sources. These sources are not only an important source of electricity, but can also be used for heating and transport. The main issue with these sources of energy is that they may cause greenhouse gas emissions if they are burned to generate electricity. This means that there is a need for more sustainable sources of energy.

The most commonly used kind of energy is called fossil fuels, which consist of coal oil, natural gas. They began to form millions and millions of years ago when prehistoric plants and animals died and were buried by layers of sedimentary rock. In the right conditions, these fossil fuels were slowly transformed into carbon-rich materials that, when burnt you could try this out generate energy. These fossil fuels won’t be renewable as they will end up being depleted in our lifetimes or in a variety of lifetimes.

Renewable energy sources, on the other hand, are continually replenished. The sun is the primary source of renewable energy, since it supplies light and heat. It is used to power our homes and businesses, as well as to drive our vehicles. Wind is a different renewable energy source, which generates electricity by spinning turbines. We have been using it since the first began to harness the wind for millennia. We also use biochemical processes to create alcohol (a clear alcohol that can be used to create fuel) from crops and waste.

Hydropower is the largest renewable energy source in the US, but wind and biofuels will soon take over. Hydropower draws on nature’s hydro cycle to harness the power of flowing water, which is then used to generate electricity.
