Here’s a bright idea...

EARTH HOUR saved us 30 tonnes of CO2 emissions.

Or better yet, why don’t we turn off the lights once a day thus saving roughly 10,950 tonnes of CO2 emissions? Or once a week, saving 1,560 tonnes, or once a month and save 360 tonnes?

But if we turned out the lights here in Ireland during “our darkest hour”, we would be in the dark all the time.
