Our use of fossil fuels – coal, oil and natural gas – has subsequently allowed our modern civilisation to flourish. It is now increasingly apparent, however, that our almost total reliance on these forms of ancient stored sunlight to meet our energy needs has some severe drawbacks (climate change, environmental pollution, regional economic disparities and resource wars), and cannot continue much longer. As the oil runs out, we need to replace it if we are to keep our vehicles going. Oil is both a convenient energy carrier, and an energy source (we ‘mine’ it). In the future, we’ll have to create our new energy carriers, be they chemical batteries or oil-substitutes like methanol or hydrogen. On a grand scale, that’s going to take ...
