What is Peak oil? Will we ever have vehicles that produce zero emissions? The debate rages on as to when fossil fuels will eventually run out, but many scientists are in little doubt that these natural resources are limited. In this audio collection we investigate some of the methods of energy creation our society might have to rely on in the future when oil reserves decrease and academics examine a variety of different energy sources from electricity to hydrogen, and evaluate whether these alternatives offer practical solutions to a world without oil. This material is taken from The Open University Course S176: Living without oil: chemistry for a sustainable future.
