Alternative energy refers to any source of energy that can be used in place of fuels and the use of which does not result in any undesired consequences. The transformation from traditional energy sources to alternative energy has brought about many economic changes across the world. It has also reduced the dependence on coal and petroleum for meeting the energy needs of the nations of the world.
Historians believe that during the late medieval period coal was used as an alternative energy source in place of wood which was damaging the environment. During the 19th century, the use of whale oil as a fuel was dominant but because of the rising prices and depleting whale oil stocks in the middle of the 19th century, less expensive petroleum was introduced as an alternative energy source. During the early 1900’s the use of ethanol alcohol as an alternative energy source came to use. Ethanol alcohol could be used in place of coal and wood as its reserves were fast depleting. During 1980’s the prices of petroleum skyrocketed and an alternative energy source was found in coal gasification.
Today, ecological friendly alternative energy sources are being used. The use of biomass over fossil fuels is common these days. Bio fuels and sources of ethanol are being promoted to be used as sources. Zero carbon alternatives have also been introduced. These are low carbon economy fuels that do not emit carbon and methane particles. The use of this alternative energy source will help to address the issue of climate change. Most countries of the world are trying to develop energy independent alternative energy sources so that they can reduce their dependence on petroleum producing countries. Natural gas is being us
Alternative energy is generated from natural sources like sunlight, wind, rain, tides and from the heat within the earth’s surface. All these resources are renewable which means these can be used without the fear of them ever getting depleted. The process of producing oil, natural gas, coal and other traditional sources of energy is a difficult process that requires a lot of time, equipment and a lot of complex physical and chemical processes. <a href="http://www.altpowerenergy.com/alternative-energy.html "> alternative energy </a> in this sense is more beneficial as it can be produced by using simple equipment and from the basic natural processes. Also can be widely produced as opposed to coal or petroleum which is available only in a few places.
