Energy efficiency can slash US energy use and greenhouse gas emissions by about 50% by 2050, getting us halfway to our national climate goals. We can achieve almost all these savings, worth more than $700 billion in 2050, by dramatically scaling up government policies and programs. This report examines 11 packages of efficiency opportunities in every economic sector and the policies that could unlock each of them. We find the greatest savings from efficient and electric vehicles, industrial efficiency and decarbonization, transportation system efficiency, upgrades to existing buildings and homes, zero energy new buildings and homes, and appliance and equipment efficiency.

The commonwealth spends almost $11 billion a year buying energy from out of state. Mass Save lowers bills and keeps money at home.
This paper highlights a central lesson for policymakers: Industrial innovation requires alignment across government programs (grants, procurement), financing mechanisms (tax credits, loans), and institutional capacity. When these three are backed by sustained commitment from the public sector, private industry, and external stakeholders, the transition from demonstration to deployment becomes viable.
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.
