Very true.

This is a common statement from Obama and the left:

"Barack Obama says the U.S. "should do bio diesel," said Pickens, "but that won't solve any problems."

By promoting biodiesel as a substitute, we have missed the fact that it is worse than the fossil-fuel burning it replaces

Over the past two years I have made an uncomfortable discovery. Like most environmentalists, I have been as blind to the constraints affecting our energy supply as my opponents have been to climate change. I now realise that I have entertained a belief in magic.

In 2003, the biologist Jeffrey Dukes calculated that the fossil fuels we burn in one year were made from organic matter "containing 44 x 1018 grams of carbon, which is more than 400 times the net primary productivity of the planet’s current biota". In plain English, this means that every year we use four centuries’ worth of plants and animals.

The idea that we can simply replace this fossil legacy - and the extraordinary power densities it gives us - with ambient energy is the stuff of science fiction. There is simply no substitute for cutting back. But substitutes are being sought everywhere. They are being promoted today at the climate talks in Montreal, by states - such as ours - that seek to avoid the hard decisions climate change demands. And at least one substitute is worse than the fossil-fuel burning it replaces.

The last time I drew attention to the hazards of making diesel fuel from vegetable oils, I received as much abuse as I have ever been sent for my stance on the Iraq war. The biodiesel missionaries, I discovered, are as vociferous in their denial as the executives of Exxon. I am now prepared to admit that my previous column was wrong. But they’re not going to like it. I was wrong because I underestimated the fuel’s destructive impact.
