House of Representatives

The indignities are piling up for Steven Chu, the Nobel laureate Secretary of Energy whom environmentalists applauded as one of Obama's best cabinet picks. His security detail won't let the lifelong cyclist bike to work. And on Earth Day, he fielded questions like this one (via Talking Points Memo) during a House hearing on the proposed climate bill. Texas representative Joe Barton asked Chu where oil comes from, and the Energy Secretary delved into plate tectonics. Barton boasted afterward that he had "baffled" Chu.

At the end of March, representatives Henry Waxman and Ed Markey introduced an ambitious federal climate bill. This is the real deal -- the legislative centerpiece of President Obama's effort to combat global warming. Transportation contributes about a third of all greenhouse gas emissions in the U.S., so any climate bill will have to green the way we get around to be effective. On that score, however, the draft legislation has some glaring omissions.
