White Paper - April 25, 2018

In this paper we examine how decision makers can more precisely assess the costs of disruptive weather events and the value of resilient distributed energy systems such as combined heat and power (CHP). CHP makes up a small percentage of the energy infrastructure in the United States despite its...

Research Report - April 16, 2018

Homeowners and renters are increasingly using technologies like smart thermostats and smart lighting, appliances, and outlets to enhance comfort and convenience. But these are not the only benefits. Smart technologies can also optimize a home’s energy use, reducing waste and lowering utility...

Research Report - April 16, 2018

State air regulators can rely on energy efficiency to help meet specific pollutant reductions required under the EPA’s National Ambient Air Quality Standards (NAAQS). However many states are not incorporating this compliance strategy into their state implementation plans (SIPs). This report...

Research Report - April 10, 2018

Wholesale energy prices have historically been volatile, and this can impose significant costs on electricity buyers and sellers. This report examines these costs in electricity markets and demonstrates the value of energy efficiency as a low-risk supply option. It estimates the value at risk in...
