Let's Use Wind to Power Cars
by Lester R. Brown
Legendary Texas oilman T. Boone Pickens is half right. We do need to harness this country's wind resources for a homegrown source of electricity, as he has been urging this summer in expensive television ads. And we do need to reduce the $700 billion we may soon be paying annually for imported oil.
But part two of Pickens's plan -- to move natural gas out of electricity production and use it to fuel cars instead -- just doesn't make sense.
Why not use the wind-generated electricity to power cars directly? Natural gas is still a fossil fuel that emits climate-changing gases when burned.
Plug-in cars are here, nearly ready to market. We just need to put wind in the driver's seat. Several major auto manufacturers, including GM, Ford, Toyota and Nissan, are producing plug-in hybrids. Both Toyota and GM are committed to marketing plug-in hybrids in 2010. Toyota might even try to deliver a plug-in version of its Prius gas-electric hybrid, the bestseller whose U.S. sales match those of all other hybrids combined, next year.

Some 30 states now have commercial-scale wind farms. The potential -- and the desire for wind energy -- is high. That's because wind wins on almost every count. It is carbon-free, cheap, abundant and inexhaustible -- and it is ours. No one can embargo the supply, the price never changes, and wind farms can be built in 12 months.
This is why shifting to natural gas to fuel cars, as Pickens recommends, isn't the best move. In contrast to wind-generated electricity, where costs are falling, the price of natural gas is on its way up.
Beyond that, there's the infrastructure question. How do we get the natural gas to the nation's service stations? These stations also would need to install pumps for natural gas, in addition to those for gasoline.
One of the attractions of pairing wind energy and plug-in hybrid cars is that it would not require new infrastructure. Indeed, a study by Pacific Northwest National Laboratory points out that the existing grid, using its off-peak capacity to recharge cars, could provide electricity for more than 70 percent of the U.S. fleet if all cars were plug-in hybrids.
While gasoline prices are probably headed to $5 to $10 a gallon, the wind-generated-electricity equivalent of a gallon of gasoline costs less than $1.
We are now in a position to launch a crash program to convert to plug-in hybrids on a massive scale and at wartime speed. This would resuscitate Detroit, reinvigorate thousands of the country's wind-rich rural communities, dramatically cut carbon emissions and quickly reduce the vast outflow of dollars for imported oil.
