I'm saying that at the present there is no economic incentive for consumers to save electricity large enough to make them switch to less energy intensive means of lighting.
We certainly won't maximize our standard of living by senselessly wasting energy. When there are two ways to light a room, yielding the same amount of light, but one uses much less energy, it is the superior one.
The tricky question is how to make it the economically sensible one for the consumer, as well.
