Alternatives for fossil fuels
The energy crisis has become a worldwide concern. It can be classified as a shortfall or interruption to the provision of energy supply. Therefore it can be termed as a shortage of fossil fuels particularly the ‘Black Gold’, which are used in the production of energy. Hence there is a need of finding alternatives for fossil fuels. These alternatives are:
* Solar energy
* Wind energy
* Tidal energy
* Nuclear energy
* Geothermal energy
Biomass is biological material from living organisms, most often referring to plants or plant-derived material. As a renewable energy source, biomass can either can either be used directly, or indirectly - once or converted into another type of energy product such as a bio fuel. Biomass includes plant or animal matter that can be converted into fibre or other industrial chemicals, including bio fuels.
Sugar and oils, such as sugarcanes and corn are used to produce bio ethanol, an alcohol fuel. It can be used like other fuels or as an additive to gasoline. But those bio fuels are more prone to the escalating Food vs. Fuel dilemma.
* Biomass is always available and can be produced as a renewable resource.
* Growing biomass crops produce oxygen and use up carbon dioxide.
* The use of waste materials reduce landfills disposal and makes more space for everything else.
* Less money spent on foreign oil.
* Additional work is needed in areas such as harvesting methods.
* Land used for energy crops maybe in demand for other purposes, such as farming, housing, resort or agricultural use.
* Some biomass projects are from animal wastes and are relatively small and therefore are limited.
* Biomass is in some cases is a major cause of pollution.
Where it is being used?
The US currently leads the world in ethanol production and use, followed by Brazil –together they account for 89% of the world’s production,...
