Energy savings has actually come to CES, of all places, as companies strive to be green and eco-friendly. Several of the large TV manufacturers have energy meters on their TVs to show how much they have reduced power consumption in recent models.

LG started the trend at the CEDIA (Custom Electronic Design & Installation Association) show in September.

At CES Mitsubishi had a meter on its 65-inch LaserVue TV, which uses a laser instead of a power-sucking lamp to illuminate a DLP displays. Next to it the company showed a high-end plasma model from a competitor.

The score? LaserVue - 98 watts, giant plasma - 500 watts. Low score wins.
