What's in are Fuel?
Bio-ethanol cannot be used as a fuel on its own – it can only make up 10% of a fuel. If we wanted to use more bio-ethanol than that, we would have to change the design of car engines. Bio-ethanol absorbs water from the atmosphere and so cannot be used ‘neat’.
Why Bio-ethonal is a good choice?
Bio-ethanol has a lower energy density than fossil fuel equivalents, so motorists are able to drive fewer miles on a liter of bio-ethanol compared with a liter of normal car fuel. Its better for the environment and for the earth.
