The 2015 study represents the 14th iteration of the RECS program. First conducted in 1978, the Residential Energy Consumption Survey is a national sample survey that collects energy-related data for housing units occupied as a primary residence and the households that live in them. Data were collected from more than 5,600 households selected at random using a complex multistage, area-probability sample design. The sample represents 118.2 million U.S. households. The 1st version of the 2015 RECS microdata file, released in April 2017, reflected preliminary household characteristics data. The file was updated in October 2017 (Version 2) to include additional square footage and household energy insecurity data. The file was updated again in May 2018 (Version 3) and included final household characteristics data, as well as final consumption and expenditures data. The final version of the microdata file was updated in December 2018 (Version 4) and contains wood consumption variables, as well as additional weather and climate-related variables used in the end-use modeling process.

This 2009 version represents the 13th iteration of the RECS program. First conducted in 1978, the Residential Energy Consumption Survey is a national sample survey that collects energy-related data for housing units occupied as a primary residence and the households that live in them. Data were collected from 12,083 households selected at random using a complex multistage, area-probability sample design. The sample represents 113.6 million U.S. households, the Census Bureau's statistical estimate for all occupied housing units in 2009 derived from their American Community Survey (ACS).

The State Energy Efficient Appliance Rebate Program (SEEARP) reports database includes rebate reports (xls) and summary factsheets (pdf) from states and territories that participated in SEEARP. With funding provided by the American Recovery and Reinvestment Act of 2009 (ARRA), the U.S. Department of Energy (DOE) developed SEEARP to spur economic activity and invest in long-term energy savings by helping consumers replace older, inefficient appliances with new, efficient models. SEEARP provided almost $300 million to the 56 U.S. states and territories to support state-level consumer rebate programs for efficient appliances from December 1, 2009 to February 17, 2012. The successes and challenges of SEEARP provide valuable lessons for designing and running a consumer-focused appliance rebate program. In addition to the SEEARP reports database, the two reports included provide a results and program design lessons.
