Sigh. In an energy-short world, phasing out coal plants is just not going to happen. Especially with high-investment replacements.

If we are only concerned with CO2 then stopping new construction (without sequestration) within a decade and then gradually decommissioning over the next half century might be acceptable from a climate change point of view i.e. it would keep us under 450ppmv CO2 concentration.

Excellent idea.

Free also.
