None ... We use AC a lot, electric cooking, electric dishwasher, electric clothes wash and dry, you think you will notice a 100 watt bulb is saving a few dollars every century when you are running the KW through the other things?
Nuclear power is the answer, but Democraps never were the brightest bulbs. Ask Jimmuh Carter for references.
Isn’t this Rep Harman ‘crap the one who used to do intelligence before she wouldn’t go along with Pelosers plans? How did she get so smart about light bulbs?
Guess my house just uses a lot of lighting. We started saving about $30 a month immediately which is a little over 20% of my previous electric bill. It paid for the 20 CFLs we installed in the first month (cost me $26 to buy the bulbs)
