You trade oil (or gas or coal) for fresh water.
We may finally be reaching the critical point in our history where the environmentalits' opposition to nuclear power can finally be seen as counterproductive. The left in this country mindlessly oppose just about everything, like nuclear power, wind power, hydropower, offshore drilling, drilling in ANWR, fighting wars for oil, big business, farming, fishing, freeways, you name it, liberals are against it.
Yet, they drive their Volvos to the Starbucks Drivethrough for a cup of coffee, letting the engine run the whole time, then drive to the gas station and buy gas from Saudi Arabia, and water their lawns with water piped from the river they didn't want to build a dam on. When the water gets cut off, and they can't water their lawn, and they have to pay a Fresh Water Surcharge at Starbucks, and the price of bottled water goes through the roof, maybe those in the middle that the libs depend on for their voting power will see that liberals are big babies, and they are holding us back.
Ok. We'll start drilling right away! As soon as enviro-wacko's let us!
