Politicians – the vast majority anyway – aren't experts in the fields they make laws about, and they rely on people who supposedly know what they're talking about to get the facts. Of course, they should also be able to see through a person's motives and not rely on biased numbers. Still, whatever the truth is about the earth's reserves, there are a lot of reasons to get off oil that don't use the word "peak." Let's stop worrying and learn to love zero-emission vehicles.I can't overemphasise the importance of persuading governments to focus attention on what's going to be a very significant issue as we move into the next decade. It is down to government to steer us towards a defossilised economy using the regulatory and financial incentives available. The technologies do already exist to deliver low-carbon transport, but we need to incentivise the private sector to deliver these solutions to the marketplace.
