Compact fluorescent lamps (CFLs) are a vital component of utility energy-efficiency programs, contributing 25 to 50 percent of total efficiency program portfolio savings in 2010. Yet the future of utility CFL programs in the U.S. is uncertain due to the Energy Independence and Security Act of 2007 (EISA) provisions for phasing in more efficient lighting. For general-service incandescent lamps, these standards will go into effect beginning in 2012. EISA does not ban incandescent bulbs; instead, it sets minimum efficiency requirements for general-purpose lighting. There are still a lot of savings to be gained from basic CFLs, which utilities can realize by continuing to promote them to residential customers. As the new EISA standards are phased in, utility programs will need to increase customer education and outreach. Though CFLs should continue to be part of utility lighting programs, utilities will likely diversify their program offerings to promote a variety of efficient lighting technologies.
