Different Energy Sources
Diverse energy sources provide us with the energy we need to live and work. These include wind, solar geothermal, biomass, as well as geothermal sources. In addition to being an important source of electricity, these sources can also be used to transport and heating. The main challenge with these sources of energy is that they may cause greenhouse gas emissions if they are burned to generate electricity. This leads to the need for greener sources of energy.
The most popular type of energy is the fossil fuels, which consist of coal, oil, and natural gas. They were created thousands of years ago, when prehistoric animals and plants passed away and were buried under layers of sedimentary rocks. When the conditions were right these fossil fuels gradually transformed into carbon-rich compounds that, when burnt create energy. These fossil fuels will not be renewable because they will end up being depleted in our lifetimes or in a number of years.
Renewable energy sources, on the other hand are continuously replenished. The sun is the most important source of renewable energy, since it supplies heat and light. We use it to power our homes and businesses as well to drive vehicles. Wind is an energy source renewable that produces electricity through spinning turbines. We have been using it since people first began to harness the wind for millennia. We use biological processes produce an ethanol (a clear, alcohol-like substance that can be used to make fuel) from waste and crops.
Of all these sources hydropower is by far the most important renewable energy source in the United States, though wind and biofuels are predicted to become the leading source of energy in the near future. Hydropower uses the natural water cycle to harness water’s swift flow, which is used to produce electricity.
