Some thoughts on whether Congress will support President Obama’s ambitious alternative energy plan. 

Marilyn Ann Brown, professor of energy policy at the Georgia Institute of Technology in Atlanta, agrees that when it comes to alternative energy, "the Obama platform is possibly more aggressive than he can get into an energy bill."

Noting that about 3 percent or 4 percent of the nation's electricity now comes from nonfossil-fuel sources, she said getting to 10 percent by 2012 "would be a heavy lift."

"Twenty-five percent by 2025 may be more doable, because it's so far out that people won't be as cautionary," she said.

One of President Obama’s first priorities is to secure passage of $800 billion stimulus package, with energy sector counting for a significant piece of that package.
