Do these momos believe as Thurber’s mother did, that electricity is some kind of magic that comes out of the sky and goes directly into the walls?
A better use of this concept would be to help people change out old A/C systems that will become very expensive to repair or replace because of the recently passed law banning certain refrigerants (sp). Sorry I don’t recall the name of the product but it essentially means a doubling of repair and replacement costs for A/C and other systems that use refrigerant.
This would actually save money in the long run because more effecient A/C systems do make a difference in our electrical usage and in our household budgets.
Nighttime electricity is mostly that, free. Most of the cost of electricity is maintaining the power lines, maintaining peak demand capacity, and fuel.
At night, there is so little demand that you shut down a lot of the most expensive generators and are running on wind, geo, nukes, and water. So for now, night time electricity costs very little at the margin.
Thurber's mother was right - it doesn't take oil or coal or anything to produce electricity - it comes from the sky...
