The News & Observer tells us this morning that Duke Energy has secured regulatory approval this week to use a form of peer pressure in its attempts to reduce its customers’ energy use.

This is the latest effort to boost energy efficiency in conjunction with a legislative mandate that also will force customers to pay for higher-cost wind, solar, and other renewable energy sources. John Locke Foundation experts have argued that one of the best things state lawmakers could do is scrap this mandate, which was designed to reduce carbon emissions in a misguided effort to fight global warming.
