Obama promotes alternative energy plan

Barack Obama focuses on his energy plan in a video message to supporters gathered at house parties to watch the fall campaign's final presidential debate Wednesday night.

Obama highlighted his agenda to spend $150 billion over 10 years on alternative energy to create 5 million new jobs.

"Now is the time to declare our energy independence once and for all," he says in the video.

The Democrat says that Republican rival John McCain's "only answer is, 'drill, baby, drill,' " citing the chant from supporters at his campaign rallies.

McCain would dispute that, since he is proposing an "all of the above" approach to energy independence that includes nuclear power, wind, solar, and clean coal, as well as more offshore oil drilling.
