Multiple studies looking at spending and savings across programs, over time and in multiple states, all show the same thing: energy efficiency is highly cost effective. Put another way, it keeps electricity affordable by meeting demand and environmental regulations at a lower cost than if we generated new power, including from clean energy resources. To help break down this discussion to key points, we released two new fact sheets today, one showing that energy efficiency is consistently the lowest-cost option for meeting electric demand and the other showing that including energy efficiency can lower the cost of Clean Power Plan compliance.
“How Much Does Energy Efficiency Cost?” includes results from studies by Lawrence Berkeley National Laboratory, ACEEE, and the US Environmental Protection Agency (EPA). The fact sheet shows how these studies provide further evidence that energy efficiency costs less than other sources of energy, and also that the costs of energy efficiency have been level in recent years. “Energy Efficiency Lowers the Cost of Clean Power Plan Compliance” looks at the results of three studies, all finding that including energy efficiency as part of state compliance plans will lower costs to utility customers. For example, a study by Synapse Resource Economics provides state-by-state information on most of the states.
