Energy Efficiency and Federalism

The U.S. system for regulating appliances—which account for a huge percentage of the nation’s carbon emissions—is a mess. Since the federal government began regulating appliance efficiency in the 1970s, the process has been characterized by frequent delays and foot-dragging, followed by lawsuits and legislative overhauls. Amidst the turmoil, a number of states have attempted to assert leadership in setting appliance standards but have often faced federal roadblocks in doing so.
