Answering your CES questions: Making big TVs greener

By Peter Nowak, CBCNews.ca

CBCnews.ca's reporters covering the Consumer Electronics show (CES) in Las Vegas are letting you be the interviewer - ask us what you'd like to know about announcements or the buzz on the show floor, and our reporters will do their best to find out.

Trevor S. asked: With TVs becoming larger and with more households purchasing these large sets, the total amount of power they are using is becoming an issue in an era of increased environmental awareness. Are TV manufacturers finding ways to significantly reduce the amount of energy their products require? When will we start to see products that use less than 50 per cent of the energy that current models require?

Great question Trevor. Panasonic's president of audio visual products, Toshihiro Sakamoto, literally just announced at CES that the company is using a technology called "double luminance efficiency," which cuts the power use in its big screens by half.

Also, thin is definitely in. Pioneer is working on 9-millimetre-thick large-screen TVs, while Panasonic unveiled plasmas that are 24.7 mm thick. Thinner sets mean fewer materials, which can reduce the manufacturing impact on the environment, cut transport costs, and so on. Panasonic says it is also putting more and more recycled materials into its sets.

From what I'm seeing so far at the show, environmental awareness isn't just a marketing term for these guys any more. It actually saves them money, so you can expect to see more of this.
