That Giant Sucking Sound May Be Your New TV
Flat-Panel Displays Devour Power, Even Before Add-Ons; Energy Star Blurs the Picture

Prices for big-screen television sets are dropping, but the cost of home entertainment may still be headed up. That is because the fancy screens shoppers are lugging home this holiday season consume far more electricity than their old-school predecessors.
Consider that a 42-inch plasma set can consume more electricity than a full-size refrigerator -- even when that TV is used only a few hours a day. Powering a fancy TV and full-on entertainment system -- with set-top boxes, game consoles, speakers, DVDs and digital video recorders -- can add nearly $200 to a family's annual energy bill.
Most consumers aren't made aware of extra energy expenses when they are shopping for a TV. Energy Star tags, a government program that identifies the most energy-efficient models, won't begin flagging the greenest televisions, when turned on, until late next year. Currently, Energy Star judges energy consumption only in standby mode, limiting its usefulness.
NASA: Danger Point Closer Than Thought From Warming
'Disastrous Effects' of Global Warming Tipping Points Near, According to New Study

Even "moderate additional" greenhouse emissions are likely to push Earth past "critical tipping points" with "dangerous consequences for the planet," according to research conducted by NASA and the Columbia University Earth Institute.
With just 10 more years of "business as usual" emissions from the burning of coal, oil and gas, says the NASA/Columbia paper, "it becomes impractical" to avoid "disastrous effects."
The study appears in the journal Atmospheric Chemistry and Physics. Its lead author is James Hansen, director of NASA's Goddard Institute for Space Studies in New York.
The forecast effects include "increasingly rapid sea-level rise, increased frequency of droughts and floods, and increased stress on wildlife and plants due to rapidly shifting climate zones," according to the NASA announcement.
