Compact Fluorescent Bulbs have now been obsoleted by Light-Emitting Diodes.
They are even more efficient and diodes have no mercury.
Typically, the low-power applications of an average apartment dweller, task lighting, background lighting, and entertainment, could all be provided by the stored power of an ordinary automobile battery, without affecting its ability to start the car the next day.
So, who needs an electrical grid?
Answering the question:
1) How do you cook your meals?
2) What happens if you don’t go to work for a few days?
3) Where do you get the power for the car?
4) What heats the water for your shower?
5) Where does the water come from?
Sheesh! One problem at a time! I just showed you how to eliminate your electrical bill.
Hold on now! Technically yes, economically no. But I don't think it will take very long. I'll be surprised if LED loghting isn't dominant 5 years from now. (I remember when LEDs first appeared on the market in the '60s -- it was "information" then and illumination was at best a science fiction dream.)
