Anti Earth-hour som protest mot klimathororna!

Having analysed eight years of NSW electricity consumption, once you control for other potential factors, the drop in statewide electricity consumption during Earth Hour is estimated at only 6.33 per cent when measured as the difference between actual and predicted consumption during Earth Hour.

But this effect is a significant overstatement of the true impact. When you examine whether the declines during Earth Hour were large compared with the rest of that day, it turns out that more than 67 per cent of the apparent decline during Earth Hour was due to factors operating throughout the entire day. When these are accounted for, the estimated reduction in electricity use during Earth Hour is a tiny 2.1 per cent, statistically indistinguishable from zero.
