The head of the World Wildlife Fund has come out publicly in favor of the electrification of the world's transportation system. James Leape, director general of WWF International, has declared that cars need to get smaller, lighter and far more efficient. Leape also said that cars should be migrating to electric drive because it is more efficient than internal combustion engines. As an organization that supports preserving animal species, the WWF has a vested interest in helping to mitigate phenomena like climate change, deforestation and other environmental problems.
All the car-makers are working on a variety of electric drive vehicles using multiple technological approaches. There are of course multiple issues with all of these including cost, durability, range, etc. There is also, of course, the issue of producing electricity to power plug-in vehicles. Somewhere there's a chorus repeating the mantra that we need to work aggressively to develop sustainable methods of generating electricity.
