It turns out that televisions are huge energy users, and are contributing significantly to greenhouse gas emissions. So much so, that the California Energy Commission is proposing to force TV manufacturers to make TVs more energy efficient, according to the Chron. Some TVs use more energy than refrigerators. Plasma TVs are the worst offenders by far. Not surprisingly, several manufacturers are strongly opposing the new standards, but one Irvine-based TV maker - Vizio - supports the plan, saying it will only add to manufacturing costs by "tens of dollars." Vizio plans to begin selling an "EcoHD" flat screen TV this year that will meet the proposed standards.
