Electric cars will not cure environmental woes

The world is falling in love with plug-in hybrids and all-electric cars. President-elect Obama wants to put 1 million on the road by 2015. GM features them, particularly the Chevy Volt, in its new business plan for a debut in 2010. The EU wants them to shrink greenhouse gas emissions in 2020 by 20% from 1990 levels. This week the Chinese auto company BYD began selling the world’s first commercially-available plug-in hybrid sedan.
No matter that these cars are not widely available; that they are priced far above traditional models; that many have a short range, making them useful only for local trips; that batteries may be prone to catching fire; and that many motorists park on the street, where charging is impractical.
For some, these issues pale in importance to saving the planet from harmful emissions of carbon, sulfur dioxide and nitrogen dioxide—all of which are released from internal combustion engine vehicles. If battery powered cars reduce emissions, environmentalists argue, they should be produced and consumers should be enticed to buy them.
But whereas electric cars don’t pollute when they’re running on batteries, they’re not pollution-free. Making the lithium-ion batteries is pollution-intensive and recharging the batteries uses electricity. And most electricity generation, from coal- and gas-fired power plants, still causes pollution.
Which means that pollution from the extra electricity for car batteries has to be weighed against savings from burning less gasoline. Whether battery power can trump the internal combustion engine, which is continually getting more efficient, depends on when drivers decide to charge their future cars, as well as how the electricity is made.
The solution is already here. I suggest you travel to California and test drive a Honda Clarity.
It uses a hydrogen fuel cell to generate electricty; the waste product is water.
The range of the car on a single tank of liquid hydrogen is approximately 280 miles.
It is expected once the car is in large scale production it will cost the same as a conventional 4 door saloon. A tank of hydrogen will cost roughly the same as your petrol.
I agree battery powered cars are a lame ducks but then so is the US auto industry (if not dead ducks).
