As climate change intensifies, many states and utilities are making long-term commitments to reduce planet-warming emissions. With buildings responsible for about one-third of these emissions, some stakeholders advocate for full electrification of homes. Others tout opportunities to use clean fuels, such as biogas and hydrogen, or gas-driven heat pumps. This paper reports the results of a home-by-home analysis of several thousand homes across the United States, looking at decarbonization options for space and water heating.
We find that electric heat pumps generally offer the cheapest way to cleanly heat and cool single-family homes in all but the coldest parts of the United States in coming decades. In very cold places, electric heat pumps with an alternative fuel backup for frigid periods (below 5°F) often minimize life-cycle energy and equipment costs.
Expanded utility-funded energy efficiency programs can significantly slow rising electricity demand and reduce electricity bills; this report explains how.
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.
This report identifies pathways for India’s cement industry to decarbonise at a pace compatible with the national climate goal of net-zero emissions by 2070.
