Press Coverage on Ban: According to the Daily Express, “A 42in plasma television uses over twice as much power as a traditional television set. Some of the larger models can take as much as electricity to run a fridge freezer”.
LA Times reports that “(California) State regulators are getting ready to curb the growing power gluttony of TV sets by drafting the nation’s first rules requiring retailers to sell only the most energy-efficient models…”. The regulation is expected to pass in mid-2009. According to LA Times, “During a peak viewing time when most sets are on, such as the Super Bowl, TVs in the (California) state collectively suck up the equivalent of 40% of the power generated by the San Onofre nuclear power station running at full capacity. Televisions account for about 10% of the average Californian’s monthly household electricity bill”. Further the article goes to describe how Plasma screens are more power hungry than LCD screens.
