I wouldn't confuse what Dubya didn't do with what Obama will likely do; two more different personalities could hardly be found. First, Obama is not beholden to the oil and coal industry. Second, he's onboard with no only PO, but shortcomings of industrial agriculture.

The biggest problem with our energy policy has been to lurch from crisis to trance. And what we need is a sustained, serious effort. Now, I actually think the biggest opportunity right now is not just gas prices at the pump but the fact that the engine for economic growth for the last 20 years is not going to be there for the next 20, and that was consumer spending. I mean, basically, we turbo-charged this economy based on cheap credit. ... There is no better potential driver that pervades all aspects of our economy than a new energy economy.

I was just reading an article in the New York Times by Michael Pollen about food and the fact that our entire agricultural system is built on cheap oil. As a consequence, our agriculture sector actually is contributing more greenhouse gases than our transportation sector. And in the mean time, it's creating monocultures that are vulnerable to national security threats, are now vulnerable to sky-high food prices or crashes in food prices, huge swings in commodity prices, and are partly responsible for the explosion in our healthcare costs because they're contributing to type 2 diabetes, stroke and heart disease, obesity, all the things that are driving our huge explosion in healthcare costs. That's just one sector of the economy. You think about the same thing is true on transportation. The same thing is true on how we construct our buildings. The same is true across the board.
For us to say we are just going to completely revamp how we use energy in a way that deals with climate change, deals with national security and drives our economy, that's going to be my number one priority when I get into office

If you are claiming that he will do nothing, you are simply making an unsupported pronouncement. Using Rudd as an example doesn't provide us with evidence of how Obama will tackle things. And unlike Clinton, Obama has a Democratic House and Senate. At least let him get into office and get a start before you criticize him for doing nothing.
