Plug-in hybrids and battery electric vehicles could provide the route towards a sustainable future for transport, helping to reduce emissions and avert potential conflicts over dwindling oil resources, according to a new WWF report.

"We should all be relying more on walking and biking, on buses and trains, to get to where we need to go," says James Leape, Director General of WWF International. "But cars will inevitably remain a major part of the transport equation. The cars of the future must be much more efficient - smaller, lighter, more aerodynamic - and they should, increasingly, be powered by electricity," he said.

The report ‘Plugged in: End of the oil age from author and Senior Energy Business and Policy Analyst at WWF in Brussels, Dr Gary Kendall is available as a free download from WWF. It provides a complete overview of the arguments for electric vehicles and deals with the hidden danger of 'alternative fuels', the environmental impact of oil sands and how electric vehicles beat hydrogen.
