More lightbulbs

Just to continue ‘harping’ on about light bulbs, the guardian yesterday had an article about changing everyone over to energy efficient lights, and they’ve got someone in the power industry to do the maths for them.

A clearer picture – and one that puts the “megawatts” value of CFLs into perspective – comes from Jonathan Smith of E.ON, Powergen’s parent company. “Changing every light fitting in all 20m households in the UK to energy-saver bulbs would result in a reduction on fuel bills of around 4.8bn – the cost of building 64 offshore wind farms, 53 biomass power stations, or 14 gas-fired power stations.”

that’s probably a lot more accurate than my maths about lightbulbs from a few weeks ago; but it’s also much much more saving than I estimated.
