My electricity bill runs about US$45 a month and I run a fairly big house for here, making no attempt to save money. The folks at the South Point are all on green power.It costs about US$5000 for them to get set up.This cost has declined for them through the years as the solar cells have gone down.
Which lifestyle costs US$150-200 a month in power? It would be very hard for me to burn four times the power- even with a cart.
Your $200 bill friend might consider tracking the usage for a couple of months.
After hurricane Keith many of us had no power for months and we still kept getting bills of around US$40. They told me they had read my meter and that was what it said.My meter was at the bottom of 100 tons of trash in the dump at the time.The meter reader had long ago set the process on auto pilot while he sat home and drank beer. He forget to quit with the fake readings when the lights went out for two months.
