If you listen to public radio, you've probably heard one of the "clean coal" interludes. There's a bunch of hooey about domestic energy and then a lovely line about "increasingly clean" coal. Well, my good friend Chris over at Energista had something to say about "clean" coal.
No amount of technological improvement on the consumption end - scrubbers or electrostatic particulate removers - will improve the mining process. Terms like "sludge dam," "hilltop removal," and "black lung" come up frequently in a discussion of coal mining, an "ongoing dirty" technology.
Even the promised technologies to make coal "increasingly clean" on the back-end haven't really reached fruition. The biggest liability of coal in a global warming world is that it's the most carbon-intensive method of producing energy and technologies such as carbon capture sequestration - where we theoretically bottle up the CO2 and inject it underground - aren't even commercialized.
The Energista analysis also points to a discussion of local justice in energy production, as wind projects are springing up in the same Appalachians that the coal mining has ravaged. While wind promises to have a significantly smaller impact on the environment, practically and aesthetically, the wind farms are all developments of energy companies from outside the area. The locals, screwed over so long by the coal mining, are naturally suspicious of someone else taking advantage of their local resource at their expense.
