    I should have thought not. Wood is renewable and every tree that grows removes CO2 from the air to build itself, whereas anthracite, being coal, is fossil fuel that is not replaced and so the COs from burning it goes into the atmosphere and stays there. Anthracite can be relatively "clean" form of coal in terms of other pollutants, whereas wood burning often produces a lot of smoke, but CO2 is the most important consideration in most people's minds.

    Burning any kind of fuel is going to release CO2. There are other renewable forms of energy which do not pollute the atmosphere, like wind, tidal, wave, solar, geothermal, and hydro. Each one has its advantages and problems engineering and econmics wise.

    Even nuclear energy arguably makes less pollution than wood burning, although everyone prefers this to be NIMBY.

    Yep. And growing the fuel to replace it recycles that CO2.

    Yep Until you burn it and release it again adding heat to the atmosphere as well as CO2

    Exactly. It keeps getting recycled, so the overall impact is small. Unlike coal; you burn it and the CO2 is there for at least thousands of years.
    (BTW the heat added by fossil fuels is nothing compared to the warming potential of the greenhouse gases emitted.)
    The heat added by burning is negligible compared to the heat retention caused by the emissions of greenhouse gases.

    Thank you all very much. I think I read that the usa still uses coal for 1/3 of its power. And they burn Bituminous coal, which is not as clean as Anthracite.
