Here's something that most folks don't think about. What are you going to do when you've got all the Electricity in the world and your last light bulb burns out? I've got a big plastic bin out in the outbuilding that has every kind of bulb you can think of in it. Everything from 7 watt night lights to 100 watt incandescent bulbs and even a few outdoor floodlights. Who needs extra toilet paper when you can't even find your way to the bathroom?
