Answering the OP a bit, here's some things I'd do off the top of my head if I were Dictator Deuce.
The first thing is to heavily promote nuclear power. I know, the NIMBY crowd is powerful on both the "left" and "right" sides of this issue, but **** those people, I'm the dictator remember? The process of approving nuclear construction needs to be streamlined significantly. Right now, it basically takes decades to build a nuclear plant because of all the red tape, and this ramps up costs. I'd also subsidize the construction of nuclear power significantly. Funding this would be a broad approach. There's a couple wars we don't need to fight, a military industrial complex that can be shaved back, I'd raise the income tax back to pre-Bush-cut levels, put a small (couple cents) tax on gasoline, oh, and I'd slash the salaries of Congress. Or just eliminate Congress entirely. Dictator, remember?
The other side of the coin will be electrifying transportation. Not an easy task. Electric motors are amazing, but our current weakness is the batteries. They're heavy, expensive, and way less energy dense than gasoline. (I did the math recently, it was like a factor of a thousand or something!) I'd push research funding into fixing this. I'd divert the tax credits for hybrid vehicle purchases to this effort. Hybrids are nice, but they're not solving the problem. I might even go all Manhattan Project on new battery technology, I think that's really the key to the Electric Revolution. We're good at producing electricity, we need to store it better.
I'd immediately put America on a New Kyoto Protocol, regardless of whether other countries signed it yet. We're America. We're supposed to be a world leader, but half our population is bitching about signing anything because waaaaahh China and India aren't going to have to work at it as hard as we do. Waaaaaahhhh. Screw that. Want to be a leader? Lead. After putting America on track, I'd lock every world leader in a room until they got on board. Anyone who wanted special treatment would run the risk of trade embargoes, tarrifs, sanctions, whatever it took. Fine, pollute as much as you want, China, but you wont be importing any of that cheap crap to America on my watch until you get your act together. What's that? Economic suicide? What, China, you think you're the only ones who can make cheap crap? I got Australia over here talking about the big market gap that you're leaving behind. We got demand, supply will come.
Then I would execute everyone who ever starred in, produced, or "directed" a "reality" television show. Look, I'm a dictator. This Green Thing is neat and all, but I have my legacy to think about. The man who rid the world of the scourge of reality television would be immortalized.
