AN ORGANISATION founded by prominent Liberal senator Cory Bernardi is promoting an anti-Earth Hour event, urging people to turn on their lights in defiance of the climate awareness movement.

Organisers of ''Human Achievement Hour'' are encouraging households to go about their normal business during Earth Hour from 8.30pm this Saturday to recognise ''the incredible accomplishments of the human race''.

''Don't be stuck in the dark with the communists. Turn your lights on!'' the senator's group urges on its website.

''While earth hour activists will be left in the dark, Human Achievement Hour participants will be going to the cinema, enjoying a hot meal, driving their car or watching television.''

Human Achievement Hour was founded last year by an American free-market think-tank, the Competitive Enterprise Institute, as a reaction to WWF's Earth Hour, which urges people to turn their lights off to promote efforts to mitigate global warming.
