With the recent wildfires in California, our PGE bill has increased lately with an average of $250 to $300 a month. Our home is an old, above ground Foundation, built in the 1940's, not a very large home but perfect for hubby, myself and our two fur babies. We are hardly home becasue of work and college. We have the one tank, chiller for the extram summer months in Nor Cal, light, filter, skimmer, heater, AC and fridge. Being that said, we just got Solar installed on our garage and have seen our Bill's cut in half. Being a college student and working full time, I do not make alot of money, so anything to lower my bill helps.
