Don’t forget, at 8:30pm tonight turn all your lights on to celebrate “Human Achievement Hour”…

(Telegraph)- A climate change campaign to get everyone to switch off their lights will not reduce carbon emissions, according to electricity experts.

Earth Hour, organised by the World Wildlife Fund (WWF), will see millions of people switch off their lights for an hour this weekend.

But the fall in electricity use for such a short period is unlikely to result in less energy being pumped into the grid, and will therefore not reduce emissions.

Even if power stations are turned off, the upsurge in turning the lights back on one hour later will require power stations that can fire up quickly like oil and coal.

Energy experts said it could therefore result in an increase in carbon emissions “rendering all good intentions useless at a flick of a switch”.

Millions of buildings around the world are expected to go dark at 8.30pm on Saturday including the Sydney Opera House and Big Ben.

WWF Earth Hour is designed to raise awareness of climate change and has been supported by Al Gore and the United Nations.
