Do your own energy audit. Get a clamp on digital amp meter and measure load drawn on each circuit , get a Kill-A-Watt meter apx 25$ and measure everything, unless small things are new and Energy Star rated idle draw can add 10-30 $ a month for things like TV radio etc, use switched strips and turn things off when not in use. My old panasonic radio and sony tv both cost me 7 $ a month to not use, I did not know it till I got a Kill A Watt. Research insulation, and new apliances. Old 15 yr refrigerators can cost 15-25 a month, I got a new sears 19,5 that costs
3.5 per month, then I recessed it into a foam enclosure reducing it to
2.5 a month. You must learn, Energy Star is a good place to start. Compare electric to Ng or Propane per Btu, Electricity for most of the US is still 50% more per Btu than Ng
