    Stop installing furnaces...

    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    What is comfort? Well, it AIN'T just TEMPERATURE!

    There = not here. Their = possessive pronoun. They're = they are
    It's = contraction of it is. Its = the possessive form of it
    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.

    I'm starting to listen now.

    Gas is the fuel of choice for new power plants. Nuclear isn't being built, coal is going away thinks to silly "green" energy policies and artificially cheap gas thanks to shale producers over-producing gas just to service their debt.

    My question is, is it productive to do this when the electricity is produced by burning natural gas to begin with?

    Might as well burn the gas directly.

    A heatpump has to have a cop of 3 just to break even in energy consumption compared to a 90%+ furnace, power generation and distribution losses considered.

    When it's 0F outside, no air source heatpump will be running with a cop of 3. All but the new inverter ones will be relying on some form of backup heat.

    Also, you have to have a really high performance building envelope, a cold climate heatpump and generously sized ducts to heat without using any backup.

    Most people don't have the dollars to afford to insulate exterior walls and spend $10 to $25k on a top of the line heatpump system.

    This may make sense in states/provinces that mostly have hydro-electric and nuclear.

    Natural gas is an amazing heating fuel - in areas without a lot of hydro capacity it would make more sense to just not burn gas to electricity. Only to use electricity to heat water and cook with at 25 to 40% effective efficiency.

    Then the gas resources would last a lot longer.
