LED light bulbs have transitioned from a fledgling technology to a major market player in recent years, with more than 450 million installed nationwide as of 2016.
Several recent sets of data show large improvements in lighting energy efficiency in recent years. First, DOE has commissioned two US Lighting Market Characterization studies – one with data on installed lighting in 2001, the other with data on installed lighting in 2012.
Every few years, a new paper comes out about the rebound effect and the issue receives some short-term attention. (When a consumer or business buys an efficient car or air conditioner, they may use their energy-efficient equipment a little more often or may spend some of their energy bill savings on things that use energy—these are examples of rebound effects.) ACEEE wrote a paper on the rebound effect in 2012, concluding that both direct and indirect rebound effects exist, but they tend to be modest.
Once again, some members of the House are trying to turn back a train that has already left the station. They have inserted a light bulb rider in the 2014 omnibus spending bill which would prohibit the Department of Energy (DOE) from enforcing the light bulb standards enacted in 2007 and signed into law by President Bush.
Our Perspective on the “Rebound Effect” – Is It True That the More Efficient a Product Becomes, the More Its Owner Will Use It?
Two recent articles have argued that as the energy efficiency of products improve, it becomes less expensive to operate these products and as a result, people increase their use of these products, increasing energy use and potentially wiping out the energy savings caused by the efficiency gains.
The New York State Energy Research and Development Authority (NYSERDA) earned recognition for three outstanding programs in ACEEE's latest States Stepping Forward report, which can be accessed here. The programs present unique, innovative models to hasten the market penetration of energy efficiency technologies in municipal wastewater facilities, commercial facilities, and industrial buildings.
