Do LCD televisions use less electricity than CRT televisions?

I upgraded from a 19" CRT television to a 32" LCD HDTV. Will I save energy?

1. LCDs use considerably less energy than CRTs, both when running and also when in standby mode. Overall, LCDs can reduce display energy use by some 60%. For example, a 15” LCD uses around 25 watts when operational and around 3 watts when in standby mode, compared with an equivalent viewing area 17” CRT that uses 80 watts when operational and 5 watts in standby mode. LCD screens recover from standby faster than CRTs and consume less power when they do they this. LCDs do not emit the same heat load as does a CRT, and this saves energy on air conditioning in a building. The uniform brightness of an LCD screen means that the screen can better tolerate variations in light levels, and reductions in lighting also saves energy. A recent Japanese study estimates that if Japan continues on it’s path towards replacing old CRTs with new LCDs so that some 76% of displays will be LCDs by the end of 2003, this will save 3 billion kWh of power consumption (the equivalent of the total power consumption of 1,000,000 households or the power production of about 3 nuclear power plants).
2. ABSOLUTELY!! Your new LCD will consume about 1/3 the power of the old CRT TV.....
