Section 111(d) of the Clean Air Act

On August 3, 2015, the U.S. Environmental Protection Agency (EPA) released a final version of the Clean Power Plan, a rule that sets performance rates and individual state targets for carbon dioxide (CO2) emissions from existing power plants. Under the authority of Section 111(d) of the Clean Air Act, the rule seeks to reduce emissions 32% nationwide by 2030, relative to 2005 levels. One of the most promising compliance strategies for low-cost pollution abatement is end-use energy efficiency. In addition to the final rule, EPA released several supplemental resources:

The Role of Energy Efficiency

End-use energy efficiency is a proven strategy to reduce energy and can help states to cost-effectively meet their CO2 reduction goals. The energy savings from end-use efficiency measures have already resulted in significant, cost-effective greenhouse gas emission reductions from the electric power sector. In fact, states, utilities, grid operators, and others have for decades relied on end-use energy efficiency policies and programs for financial, legal, economic development, and environmental purposes. While energy efficiency was not used to calculate state pollution reduction targets, it remains states’ cheapest and most readily available option for achieving substantial and reliable emission reductions.

ACEEE has developed a number of resources to help states and stakeholders understand and assess the energy, environmental, and economic benefits of energy efficiency as a means to reducing pollution:

Our “template” series provides guidance to help states take credit for emissions reductions from multiple energy efficiency policies and programs.

Rapidly deployable energy efficiency policies can achieve a majority of EPA’s required greenhouse gas reductions by 2030. See how here. (Coming soon!)
