Building Efficiency

The biggest opportunity to improve the nation's energy situation is a major investment program to make homes and businesses more efficient, according to a study released Wednesday by the consulting firm McKinsey. An investment of $520 billion in improvements like sealing ducts and replacing inefficient appliances could produce $1.2 trillion in savings on energy bills through 2020, the study found.

Such a program is expected to reduce end use energy consumption in 2020 by 9.1 quadrillion BTUs, roughly 23% of projected demand, potentially abating up to 1.1 gigatons of greenhouse gases annually.
