The air handlers of forced air gas furnaces provide the energy to move air through the furnace (and central air conditioner), and distribute it to the rooms of a house. The amount of electricity these require varies enormously, even within size categories, but averages about 3.4% of the site energy use of the furnace, or 10% of the source energy. Improving the motor and fan systems of residential furnaces and heat pumps promises substantial, cost-effective efficiency gains.
The commonwealth spends almost $11 billion a year buying energy from out of state. Mass Save lowers bills and keeps money at home.
Utility energy efficiency programs have increased investment in low-income households, but significant gaps remain. This report examines spending and savings trends across 48 major U.S. utilities, identifies barriers to expanding low-income programs and highlights policies and program strategies that can improve energy affordability and equitable access to efficiency upgrades.
The United States faces interlocking energy challenges: rising home energy bills and gasoline prices; new demand for electricity from data centers and other loads; high greenhouse gas emissions from burning fossil fuels.
Now, a new era of energy efficiency progress in our buildings, transportation, and industry is needed to meet this moment. This wide-ranging study finds a massive opportunity.
