The £12m defences of the most heavily guarded power station in Britain have been breached by a single person who, under the eyes of CCTV cameras, climbed two three-metre (10ft) razor-wired, electrified security fences, walked into the station and crashed a giant 500MW turbine before leaving a calling card reading "no new coal". He walked out the same way and hopped back over the fence.
All power from the coal and oil-powered Kingsnorth station in Kent was halted for four hours, in which time it is thought the mystery saboteur's actions reduced UK climate change emissions by 2%. Enough electricity to power a city the size of Bristol was lost.
I'm all for using less electricity and treading more lightly on this world, and I've gone for battery powered devices for all my comms, but central heating is still from mains power and if there's a power cut, its going to get really cold really quickly.
