   How the wrong sort of radio adds to C02 emissions

   David Adam, environment correspondent
   Monday November 13, 2006 the  Guardian (London, UK)

   Digital broadcasting is increasing the threat of global warming by
   pumping massive amounts of extra carbon dioxide into the atmosphere,
   official figures suggest. The millions of Britons who listen to the
   radio through their power-hungry digital televisions and computers
   together release an extra 190,000 tonnes of carbon dioxide a year.

   According to the Stern review of the economics of climate change, that
   amount of carbon pollution will cause ?8.5m damage to the planet.

   Figures from the [UK ratings ] industry body Rajar show that 22% of people in
   Britain now listen to the radio through their digital televisions at
   least once a week. About 12% listen to stations through their
   computer.

   Computers and TVs consume significantly more electricity than radios.
   Assuming a power rating of 200W for a TV and 250W for a computer, if
   one in five of the population listens to the radio via those devices
   for two hours a week, they will produce about 210,000 tonnes of carbon
   dioxide each year.

   A 20W radio turned on for two hours a week by the same number of
   people would produce about 18,000 tonnes a year; digital and
   traditional radios use roughly the same amount of power.

   Keith Marsh, of the Energy Saving Trust, said the new LCD and
   plasma-screen TVs were rated at up to 390W.

   The extra emissions from digital listening account for almost a fifth
   of the estimated 1m tonnes a year that could be saved by replacing
   every traditional lightbulb in Britain with a low-energy version.

   A government study estimates that the rise in gadget ownership and the
   switch from analogue to digital TV could boost the electricity usage
   of the consumer electronics sector by 60% by 2010.
