Residential interest in CFLs, LEDs rising

Tools

The number of U.S. households using energy-efficient compact fluorescent lamps (CFL) or light-emitting diodes (LED) is increasing, according to E Source research conducted in partnership with the Nielsen Company.

In fact, 87 percent of households are using at least one CFL or LED in their homes and 77 percent are using three or more -- up from 86 percent and 75 percent in 2011, respectively.

The large-scale Energy Audit survey of approximately 32,000 households focused on behaviors and attitudes related to home energy use, including energy-efficient lighting.

The research shows that consumers are primarily motivated to use CFLs or LEDs to save money. Those whose motivation is improving the environment are slightly more likely to use multiple CFLs or LEDs in their homes.

Residents living in large homes (5,000 square feet or more) aren't necessarily using the most CFLs and LEDs even though they have the greatest ability to do so. Larger homes are less likely to use 11 or more CFLs or LEDs when compared to slightly smaller homes (between 3,000 and 5,000 square feet), despite the fact that they likely have more light sockets and an increased opportunity to use 11 or more energy-efficient bulbs, according to E Source.
