Most energy efficiency programs target only one fuel, usually electricity or natural gas. While they achieve savings, they sometimes miss opportunities by failing to address other fuels. Dual-fuel programs, on the other hand, have the potential to save more energy, reduce program costs, and improve customer satisfaction.

In 2013, the American Council for an Energy-Efficient Economy (ACEEE) released a study of the nation’s largest multifamily home markets and the customer-funded utility energy efficiency programs that serve them. Using a combination of housing, utility, and policy data, ACEEE analyzed the potential to create or expand these programs in metropolitan markets.

Energy is a complicated topic, and energy performance can also be challenging to determine. This book is about understanding and shaping energy performance of an entire economic sector, using the residential sector as the example, although not at a detailed level. The historical record of attempts to reduce energy use or carbon emissions of countries and the world is primarily one of failure.

This is the third in a series of papers intended to guide states as they embark on the path to Clean Power Plan (CPP) compliance. As one of many approaches to reducing pollution and complying with the CPP, states and localities can offer energy efficiency programs to low-income households or businesses and community-based organizations that serve low-income communities.

Communities are at the forefront of the energy transition: citizens are increasingly asking their cities to develop and act on ambitious plans, and community leaders are seeing the social, political, and economic benefits of doing so. Even so, no standard roadmap or methodology exists to help communities transform their energy use.

America has entered the “coal cost crossover” where existing coal is more expensive than cleaner alternatives. This report shows that today, local wind and solar could replace 74 percent of the U.S. coal fleet at an immediate savings to customers. By 2025, this number grows to 86 percent of the coal fleet.
