True. Another reason for rates going up in many cities is that of natural gas interests recently pushing the government to shut down some coal-fired plants and pushing up the costs of others.
Well, Nat gas is dirt cheap and a good economic choice today.
Of course in 10 years it may not be. Demand and supply will equalize.
You can’t beat coal.
BTW I’m a big fan of passive solar. Have even designed a HW heater I’ll put in in spring when I have the money and weather. People are crazy not to do the simple things to utilize passive.
