A shop replaces its old lights with efficient lamps and predicts that its electricity bill will fall by the same proportion as the lamps' energy use. The prediction quietly assumes that lighting accounts for the entire bill and that the hours of operation will stay unchanged. In fact, refrigeration uses much of the shop's electricity, and the brighter interior encourages the owner to remain open later. Efficient lamps can still save energy for each hour of lighting, but the total bill is shaped by other uses and by behavior after installation. A claim about a component does not automatically scale up to a claim about the whole system. To evaluate such a prediction, one must expose the assumptions connecting the measured improvement to the promised overall result.
