We're so dependent on electric power. Weeks ago we were cut off for half a day. Even the water supplies were stopped because the pump of the water storage in our part of the town was empty and didn't refill. And this morning the radiators in the whole flat were cold. Luckily the oil pump could be restarted before we went freezing. These things show how our civilized world is still a walk on the rezor's edge as long as we depend on fossil fuels.
