I get the same ******** letters. Funny thing is, I built my house 6 years ago and got it Energy Star certified through LG&E. It's an 1800 sq ft home with spray foam, 20 seer hvac, super effecient windows, all LED lights, energy recovery ventilators, gas tankless water heater, etc...
My electric bill rarely goes over $100. Despite being HERRS rated below 50, they still say I'm using something like 130% of my neighbors. This is even more ridiculous considering most of my neighbors homes are over 3000 sq ft and over 150 years old.
I want to mail them back the response envelope full of poop every time they send me that garbage.
