Plug in cars better: WWF

MUMBAI: Increased use of plug-in electric and hybrid vehicles would be a way to a transport future that doesn't risk climate catastrophe, a major new World Wide Fund for Nature (WWF) analysis has found.

The report also finds that the electric vehicles can be three times more efficient than hydrogen-fuelled vehicles. More importantly perhaps, electric vehicles can be widely introduced using existing technologies and distribution infrastructure. The WWF study released in Gland (Switzerland) and Brussels (Belgium) also finds that cleaner power generation and more use of renewable fuels in power generation will make it certain that the comparative efficiency and pollution advantages of plug-in transport will improve into the future, while the future of liquid fuels is one of increasing resort to dirtier sources that will take more energy to turn into fuels.
"Plug-in electric and hybrid vehicles also reduce the risk of conflict over less oil more and more concentrated in relatively unstable areas of the world," WWF-India said in a statement.

The study 'Plugged In: The End of the Oil Age'
considers the future of a transport sector now 95 per cent dependent on liquid hydrocarbon fuels and examines the impacts and practicalities of electric, coal-to-liquid, gas-to-liquid, natural gas and hydrogen powered transport for the future. It finds that vehicles running solely or partly on grid-connected electricity are more efficient and less greenhouse gas intensive than all alternatives, even with most power now being generated using fossil fuels.
"We should all be relying more on walking and biking, on buses and trains, to get to where we need to go. But cars will inevitably remain a major part of the transport equation," said James Leape, Director General of WWF International, according to the statement. "The cars of the future must be much more efficient -- smaller, lighter, more aerodynamic -- and they should, increasingly, be powered by electricity."

"Coal-to-liquid fuels are costly, energy intensive and extremely polluting, and have previously only been used on any significant scale in countries facing a state of emergency," the report's author Dr Gary Kendall was quoted saying in the statement.

"Automotive transport is ripe for transformation," said Dr Kendall. "We need to accelerate the commercialisation of vehicles with diversified primary energy sources, high efficiency and compatibility with a sustainable, renewable energy future. The electrification of automotive transport offers a promising way to achieve this objective." To do so, the report recommends dismantling market barriers to superior technologies and removing a host of hidden and overt subsidies to liquid fuel use.


Vehicles should be subject to similar energy labelling and efficiency improvement requirements as other energy-consuming appliances. Liquid-based measures of fuel economy (e.g. litres per 100km or miles per gallon) and CO2 emissions targets should be replaced with technology-neutral indicators of energy consumed per kilometre. "We cannot depend upon today's dominant transport solution providers to drive the shift away from liquid hydrocarbon fuels," Dr Kendall said. "Other business sectors – such as power utilities for instance – will come to the fore in recognizing the business opportunities of grid-connected transport. "But ultimately, leadership on moving to the best transport fuel mix will need to come from governments.
