A new report by Vice President Biden, which President Obama mentioned briefly in an appearance Tuesday, projects that the number of U.S. homes with smart meters will jump from about 8 million now to 40 million by 2015.
In a memo to Obama, entitled "Progress Report: The Transformation to a Clean Energy Economy," Biden says the Recovery Act will help fund the installation of smart meters in 18 million homes. As of January, he says 8 million homes had such meters, which track energy usage by month, week and even hour.
Biden projects that, through a mix of public and private investment, the number of homes with smart meters could skyrocket to 40 million within six years.
