Energy efficiency is a cornerstone of good state and regional energy policy. Investments in efficient equipment like lighting, appliances, and industrial motors reduce consumer energy bills and also reduce the need for expensive energy infrastructure like transmission lines and power plants. Acadia Center works to ensure that programs are effective, well-funded and reach a wide spectrum of customers with the deepest possible energy and cost savings for each participant.

Efficiency investments in leading states have deferred the need for nearly half a billion dollars in new energy infrastructure projects, produced $19.5 billion in economic benefits, cut electric use by 124,000 GWh, and avoided 51.3 million metric tons of CO2 pollution. Acadia Center’s macroeconomic studies show that efficiency investments create jobs, keep energy dollars at home, and help to grow local economies.

The challenge is to build from this strong foundation to reach for even greater savings and aid the transformation to a cleaner electric grid. These goals can be achieved by maximizing efficiency investments that are available and cost effective and focusing on ways efficiency can minimize infrastructure investments and integrate renewables. Acadia Center helped create the policies that have led states to top-in-the-nation investments in energy efficiency. Acadia Center pioneered the stakeholder council model as a means of ensuring consistent implementation, evaluation and diverse representation in the energy efficiency procurement process. Staff members currently hold appointed seats on these councils in Massachusetts, Connecticut, and Rhode Island. Acadia Center works with businesses, utilities, regulators and others to make sure that programs meet their goals and reach all customers.

  • The Regional Greenhouse Gas Initiative: Ten Years in Review

    This report analyzes data since the launch of the country’s first multi-state carbon reduction program. The analysis shows that CO2 emissions from power plants in the RGGI states have fallen 90% faster than in the rest of country, while economic growth in the RGGI states has outpaced the rest of the country by 31%. The program has also driven substantial reductions in harmful co-pollutants, making the region’s air cleaner and its people healthier.

  • Investing in Connecticut’s Transportation Future

    This Acadia Center analysis illustrates the benefits of a new approach for Connecticut to reduce transportation pollution while improving the system to better meet its residents’ needs. The analysis shows that, if designed well, a regional cap-and-invest policy developed through the Transportation & Climate Initiative (TCI) could enable the state to make over $2.7 billion in crucial transportation investments by 2030, which would generate over 23,000 long-term jobs and $7 billion in economic activity.
