THE LOWLY LIGHT BULB COULD HELP REDUCE CLIMATE CHANGE

ANDY MCSMITH, INDEPENDENT, UK - The low-energy light bulb and other
efficient lighting systems could prevent a cumulative total of 16
billion tons of carbon from being added to the world's atmosphere over
the next 25 years, according to a report by the International Energy
Agency.
The agency said it would not need any technology that is not already
widely available and - far from costing money - it would save more than
L1,300bn. The light used for homes and offices is a major cause of
climate change and also creates "light pollution", which means that city
children grow up never seeing the stars. . .

Artificial light accounts for almost one-fifth of the world's
electricity consumption, substantially more than the output of all the
nuclear power stations in the world. It generates around 1.9 billion
tons worth of carbon a year, equivalent to nearly three quarters of the
carbon coming from the exhaust of all the cars and light vehicles in the
world.
