Excellent analysis of the reason why our present, oil-dependent transport system cannot be sustained - due to its impact on the climate, but even more urgently, due to the impending peak and subsequent decline in world oil supplies. Many books in this area do a great job of outlining the problems without proposing possible solutions, but "Transport Revolutions" makes a detailed set of proposals, focusing heavily on the increased use of electricity in land transport. A great strength of the book is the extensive referencing, which makes it a very valuable resource when writing and presenting in these areas. A weakness is that the book doesn't address what might happen if its proposals don't work - in other words, there is no "Plan B", no consideration of a more decentralised, localised response to the end of the cheap energy era.
