Energy efficiency of TVs rises by 60%

Posted by Ross Lammas on 11 April 2012 at 9:02 am

When plasma and LCD TVs first arrived in the shops, we were dazzled by their stunning picture quality and screen size, and overlooked the fact that, compared with most tube televisions, these beasts were energy guzzlers. This was something the salesman, wowing us with bright colours and a 42 inch screen, would neglect to mention.

The good news is that our research shows that TVs are now, on average, 60 per cent more efficient than they were five years ago. In 2006 a 42 inch Plasma could have cost you £78.80 per year to run (at today’s prices). Now, thanks to public awareness and advances in technology, a similar model uses nearly six times less energy, produces 264.90 kg less carbon and costs only £13.76 to run per year.

We compared the running costs of 1,800 televisions and found that between October 2006 and July 2011, the average amount of energy flat screen TVs use has decreased and, in addition, the decrease in stand-by consumption is nearly 100 per cent.  This is good news for the environment, as TVs account for around 6-8% of the global domestic electricity usage, and for consumers' electricity bills.

While we welcome the stunning reduction in energy consumption of TVs, consumers need to be wary of old energy-hungry plasma models. They have become easier to spot since energy labels for TV’s become mandatory last December 2011. But my advice is go for an LED model.
