The fact is most of the world’s energy comes from non-renewable sources (coal, oil, etc) and some alternatives are rather dangerous (namely Nuclear). So, what is the alternative? Well the alternative is a fuel called Glycerine, a by product of Bio-Diesel production. The fuel is used to power Formula E cars and is used to power the diesel generators that charge the cars. So, the idea is can Glycerine the used to provide power to electric cars. Crucially, could it also be used to power more conventional petrol- and diesel-powered vehicles?
