A new DOE proposal would cement a big leap in lighting efficiency but Congress is preventing even bigger savings
Together, the 2009 standards and the proposed increases announced last week dramatically improve reflector lamp and fluorescent tube lamp efficiency by 70% and 23% respectively
DOE estimates that proposed standards would yield between $8.6 and $24 billion in net savings for businesses and would reduce CO2 emissions by 298 million MT on equipment purchased over 30 years. Energy savings are estimated at 5.4 quads (annual US energy use is about 98 quads).
The final rule is expected in April 2014 (DOE missed the January 2012 statutory deadline.)
