The balloons have all popped, the cheering is over, and Barack Obama is already hard at work, preparing for his presidency. The good news for earth-lovers is that, as Obama told CNN shortly before the election, his climate-friendly energy policy will be his first priority, after dealing with the financial crisis.

Unlike his predecessor, Obama fully buys into the urgency of climate change and is determined to do something about it. Intelligently, he also frames energy as both a national security and an economic issue — which should make it an easier sell to our representatives in Congress and our neighbors at home.

The centerpiece of Obama’s energy plan (read it on the Obama campaign website) is a 10-year $150 billion (yes, with a “b”) effort to spur forward the cleantech industry. As part of that plan, he envisions creating five million new “green collar” jobs, an agenda long advocated by social justice activists like Green for All president Van Jones.

Obama is also a big proponent of energy efficiency, calling it the “cheapest, cleanest, and fastest energy source” and one that could reduce U.S. consumption of electricity 15% from projected demand for 2020. His plan calls for the retrofitting of federal buildings to increase their energy efficiency by 25% within five years, with the long-term goal of making all federal buildings zero emissions by 2025. He wants to weatherize one million homes annually — cutting down both on carbon emissions and on heating and air conditioning bills. By 2030, he wants to see all buildings in the country at zero emissions.

On the renewables front, Obama wants to see the United States getting at least 10% of its electricity coming from sources like solar and wind by the end of his first term, and 25% by 2025. Obama also favors a cap-and-trade system with the goal of reducing greenhouse gas emissions 80% by 2050.

And in what should make environmentalists particularly happy, he wants to develop a system of incentives to reward farmers, ranchers and other landowners for planting trees and restoring grasslands.

Too bad, though, about his support for clean coal. But hey, you can’t have everything.

So what do you think about his energy plan? Green enough for you? Do you think he'll be able to pull it off?
