Coal vs. Passive Home Heat

Two energy articles came up in sequence on the New York Times website just now, one on the increased use of coal for home heat in the United States, and another on the construction of passive homes in Germany that don't even have a furnace and rely instead on advanced heat exchange and ventilation systems combined with insulation and airtight construction. Hm, who's on the right track? My friend Warren Wilczewski wrote recently for Policy Innovations on Germany's other wise moves in shifting from atoms to photons.
