having enough spare power generating capacity in the grid just so you can meet the demand when everyone turns their kettles on during the advert break of some soap opera watched by millions, it's crazy
my dad did some of the civil engineering stuff on some pumped storage system when I was a kid and he was explaining this to me, use spare power in the grid to pump water uphill, then let it run back downhill and generate the extra watts when they're needed
and even then I remember thinking "that seems like a pretty hamfisted way of solving that problem"
which is 100% purely itunes fault, I changed absolutely no setting and did nothing to cause it like all the apple fanboys hound me over. "oh you must've changed the media folder setting cause ur a pc dumbtard" etc etc
