As public utility commissions gather to discuss policies and programs that regulate how energy is used and moved in America, HPC releases its report, A Policymaker’s Guide to Incorporating Existing Homes into Carbon Reduction Strategies and Clean Power Plan Compliance to policymakers outlining key ways in which existing homes are a key aspect to carbon reductions strategies, with details on how they complement the Clean Power Plan (CPP). Along with providing a succinct and educational overview of how the residential community fits into the CPP, HPC solidifies why it is imperative that residential energy efficiency become an integral part of state carbon regulation strategies.
