This story on energy efficiency opportunities in the US has been bouncing all over the internet:
A McKinsey report on energy efficiency in the United States, released today (see related post), cites $1.2 trillion in potential savings by 2020 if the country first invests $520 billion in efficiency improvements like better insulation for buildings.
The big question is, what policies can help us to get there? The report cites several "success stories." Potentially, some could serve as models for other programs or policies.
