If every one of 110 million American households bought just one ice-cream-cone bulb, took it home, and screwed it in the place of an ordinary 60-watt bulb, the energy saved would be enough to power a city of 1.5 million people. One bulb swapped out, enough electricity saved to power all the homes in Delaware and Rhode Island. In terms of oil not burned, or greenhouse gases not exhausted into the atmosphere, one bulb is equivalent to taking 1.3 million cars off the roads.So 110 bulbs uses as much energy as 1.3 cars? Even if we were running generators off the rear wheels I don't think so, and commercial electricity production -- which we actually use for light bulbs -- is more efficient than that by (guessing) an order of magnitude or more. Anyone have any better numbers? Or a way to justify these?
