I had pointed out a Larry Summers speech where he suggests the importance to have energy efficient buildings ( The speech was in a different context though).
I was reading Obama’s stimulus plan and see the learnings being applied (as Summers is part of the “Change” team):
Today, I am announcing a few key parts of my plan. First, we will launch a massive effort to make public buildings more energy-efficient. Our government now pays the highest energy bill in the world. We need to change that. We need to upgrade our federal buildings by replacing old heating systems and installing efficient light bulbs. That won’t just save you, the American taxpayer, billions of dollars each year. It will put people back to work.
