“A dumb electric meter adds up all of the kWh used over the course of a month regardless of when that power was made and how much it cost to make. Some homes use a lot of power during the expensive mid-day period, while others use most of their power at night. If those two homes used the same monthly total number of kWh, and they had a dumb meter, the power company has to charge them the same amount for monthly service because it doesn’t know when each house was using power. An executive I know likens this to weighing your grocery cart when you check out at the supermarket and charging you per pound of groceries in the cart, without prices for any of the specific items you chose to buy that day, whether it be caviar or pet food.”
