California Proposes Ban on Energy-Hogging HDTVs Starting in 2011
The California Energy Commission is proceeding with a proposal this summer to ban the sale of TV sets that do not meet new efficiency standards when they are turned on and displaying a picture — a measure of power consumption that is not currently regulated at all.
But the market and technological advances may already be advancing this goal, as large-screen plasma sets fall out of favor and LCDs become more energy efficient.
The CEC proposal is set up as a two-tiered system. The first enforces efficiency standards beginning in 2011 and would save 3,831 gigawatt hours (and bring down overall TV energy consumption by 33%) by placing a cap on the active mode power usage (in watts) of individual TVs. Current standards in California only regulate TVs in standby mode, at a cap of 3.0 watts.
According to the Commission, energy used in standby mode only represents about 5 percent of all TV energy consumption.
The program's 2013 second stage promises to reduce energy use by 49%. If they are enforced, the new standards are expected to save Californians between $18 and $30 a year per TV set in energy costs. As noted by the Commission, current LCDs use about .27-watts per square inch and plasmas use 0.36-watts per square inch.
