Research Report U1907 - September 18, 2019

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...

Research Report U1904 - July 24, 2019

The City Clean Energy Scorecard measures the progress of city policies and programs that save energy, promote renewable energy, and reduce greenhouse gas emissions. It also focuses on efforts to embed equity in policymaking. We ranked 75 large US cities for their energy efficiency and...

Research Report U1902 - February 20, 2019

The lifetime of energy efficiency programs and measures ranges from a few months to several decades. Nevertheless, most energy efficiency policies are designed around the first year of savings. This report describes recent policy changes in some states and Canadian provinces to measure the value...
