The Green House

Obama plans to make the White House more energy-efficient:

Obama will be sworn in on Jan. 20, and he said he wants to work quickly to make the White House "green."

The president-elect said he plans to sit down with the chief usher for the presidential mansion and do an evaluation of its energy efficiency.

"Part of what I want to do is to show the American people that it's not that hard," Obama said.

Asked whether he'll be tiptoeing around at night, turning off the lights, Obama said he isn't going to be obsessive about it.

"But I do that in my current house," he added, "and there's no reason why I wouldn't do it in my next one."
