Big screen TVs can suck a lot of power. If you've looked at big screen TV's lately you may have noticed that some of them have the Energy Star label. Buying an energy efficient model can save a lot of money over the life of the unit. It definitely makes sense to look for an Energy Star TV, but not all Energy Star TVs are equal. You should look past the Energy Star label and find out the actual power usage of the TVs.
Difference In Energy Star Models
Lets do a quick comparison of two models:
Samsung 55" LCD model LN55C630K1F on sale for $1709.99 at Bestbuy
or
Sony 55" LCD model KDL-55EX500 also on sale for $1,709.99 also at Bestbuy
The TV's are both 55", they're both LCD technology and they are both on sale for $1,709.99. Both of the TV's carry the Energy Star certification. You would expect that they would use similar amounts of electricity, but they don't.
The EnergyStar site has data on the individual model TV's.
According to the Energy Star site the Samsung LN55C630K1F model is supposed to use 187.54 kWh a year in electricity. At 11¢ per kWh that would be $20.63 /year.
The Energy Star page for the Sony KDL-55EX500 says it uses 267.84 kWh. $29.46 a year at 11¢ /kWh
The Sony model uses 80.30 more kWh in electricity per year. Thats 43% more than the Samsung TV's electricity use.
Electricity Use Can Matter a LOT
If you don't think that the electricity use of your big TV is a big deal than think again. The models mentioned above are efficient 55" TVs that use just $20 or $29 of electricity. What about less efficient TVs that don't even qualify for Energy Star?
