In New Zealand, almost 80% of electricity is produced by hydro, thermal and other renewable sources.
When everyone turns their lights off at the same time, the grid has to be rebalanced. Hydro and thermal plants cant be regulated like that, and what happens is some are taken offline. Then the gas fired plants have to increase electricity production to pick up the slack.
And then everyone burns candles.
