Currently there are many different kinds of energy sources around the world. These different types of energy sources can be generalized into renewable and non renewable sources. Solar, wind, geothermal, biomass, hydro water and tidal energy come under the renewable energy sources. On the other hand coal, uranium, nuclear, gas (natural and non-natural) comes under the non renewable sources. Of all these sources oil and gas (fossil fuels) are the most commonly used energy sources. Almost 85  of the primary energy requirements of the world are being fulfilled from these fossil fuels.

Biomass is a renewable energy source in which biological materials are derived from the living or the recently living organisms. The energy is derived from different energy sources such as garbage, wood, waste, landfill gases and alcohol based fuels. Moreover biomass can also include biodegradable waste which can be burnt to produce energy and be used as a fuel. The converted form of biomass which can be used is a fuel is known as bio fuel. Bio fuels have the potential to reduce the greenhouse gas emissions, as well as reduce the dependence on fossil fuels which are rapidly depleting. The most common form of bio fuel is ethanol. Ethanol can be used in petrol cars as a replacement for gasoline or it can be mixed with gasoline according to a set percentage.

Ethanol is produced by the fermentation of the sugar.  In order for this to be used as fuel, water has to be removed from it in a process known as distillation. Distillation removes almost 95 of the water but further water needs to be removed and thus it goes through another process known as dehydration. Thus this final process produces ethanol which is ready to be used as a fuel.

The normal cars can support a blend of ethanol and gasoline to be used as a fuel but increasingly governments are pushing car manufacturers to make their engines more suitable towards ethanol so that higher ratio of ethanol can be used as a fuel.  A new generation of flexible fuel vehicles are making inroads which can run on gasoline, ethanol or both. As the fossil fuels are depleting with each passing day, ethanol promises to be the fuel of the future with almost endless supply and thus ensuring a bright future for the coming generation.
