How much coal is required…

…. to run a 100-watt light bulb 24 hours a day for a year?

Came across the useful – and frightening – link on How Stuff Works.  Take a look – the answer is a lot and a lot of carbon emissions as a by product.

Timely as news from the government to phase out traditional light bulbs.  But why wait till 2012 –  they are already yesterdays news in Australia and elsewhere.

Greenpeace director John Sauven, reported in the Guardian, said: “For every year of delay in getting rid of these bulbs, 5m tonnes of CO2 are emitted into the atmosphere unnecessarily.”
