Seriously invest in led lightbulbs for everything, caulk windows and doors, all the obvious stuff, make sure chimney flues are closed and not so obvious stuff, get a smart thermostat, leaving the house at 67 while you are not home is a luxury, like my house automatically turns down to 62 when not occupied but only takes 30 minutes to get up to 68, but yeah Allegheny county is crazy expensive, Duquesne light, vs West Penn power, gas and water also
