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.
These meters, as noted in an earlier Green House post , have sparked criticism in California, where some users say they do not accurately measure power usage and their installation costs have increased utility bills.
