Reported in The Guardian, in the first half of 2010, there was a drop in the amount of electricity generated from non-carbon sources. This was due to lower-than-expected wind speeds and rainfall.
Sceptics of renewable energy need not relax. The supply and price of gas and oil are likely to become volatile as supplies dwindle and demand from the emerging economies, most notably Brazil, Russia, India and China, rises.
This rather reinforces the point that building a transport system based on replacing petrol- and diesel-fuelled vehicles eith electric vehicles without attempting to reduce total vehicle mileage or promoting sustainable travel modes is a strategy that is fraught with risk.
