BOSTON (CBS) – As technology continues to improve, service providers often adapt quickly to use these new tools. But though these changes are almost always good for the company, how do we make sure they are also good for the customers? National Grid, among other power companies, has begun testing “smart meters,” which measure and record the use of electricity at a particular residence. While the power companies claim these meters help deliver electricity more efficiently and restore power faster when there is an outage, critics claim they are an invasion of privacy, a potential health risk, and an excuse to charge more down the road. Dan sits down with Ed White from National Grid and Clare Donegan with Halt Smart Meters Massachusetts to hear both sides of the issue.
