Different energy sources supply us with the energy we need to live and work. They include wind, solar geothermal, biomass, as well as geothermal sources. In addition to being the primary source of electricity, these sources can also be used for heat and transport. The biggest issue with these sources of energy is that they can create greenhouse gas emissions if they are burned to produce electricity. This means that there is a need for more sustainable sources of energy.
Fossil fuels are the most well-known form of energy. They include coal, oil and natural gas. They began to form millions and millions of years ago when animals and plants of the past passed away and were then buried beneath layers of sedimentary rock. In the appropriate conditions, they gradually transformed into carbon-rich materials that, when burned produce energy. These fossil fuels are non-renewable since they will exhaust in our lifetimes or even in many lifetimes.
Renewable energy sources are replenished continuously. The primary renewable energy source is sunlight, which gives warmth and light. It is used to power our homes and businesses as well to drive our vehicles. Wind is a different renewable energy source, which generates electricity through spinning turbines. We have been using it since people first began to harness the wind for millennia. In the end, we employ biological processes to create ethanol (a clear alcohol that can be used as fuel) from waste and crop residues.
As a result hydropower is the most significant renewable energy source in the United States, though wind and biofuels are predicted to take the lead soon. Hydropower uses the natural water cycle to harness water’s swift flow, which can be used to produce electricity.
