TV & Internet...

How many hours a day do you use your TV? One? Two? Five? More? 

Okay, let's ask a more important question: is your TV energy efficent?

Don't know the answer? That's okay, because until now it was hard to know if your television was a power hog or not. But now new rules from the EPA's ENERGY STAR will make it easier to buy an energy-efficient model -- just in time for the holidays!

Old ENERGY STAR rules only rated TVs according to how much power they used while off or in "standby" mode. The new rules go several steps further, requiring energy efficiency when TVs are on, and also guiding the use of external power supplies when necessary. "This new specification is important," says the EPA, "since televisions being sold now are larger, in use more hours a day, and offer more vibrant pictures, which can impact the amount of electricity they use. In fact, some of the largest, high resolution televisions can use as much as 500 kWh per year."

TVs with an ENERGY STAR rating will use an estimated 30% less juice than other TVs, so this will really make a difference as people replace their old models with new, higher-tech screens.

So far, 229 TVs conform to the new rules. They include 19 plasma models, 199 LCD models, and 11 "others".
