The Breakthrough Institute comments:
Coal electricity declined by 12.5
percent in 2012, mostly driven by the switch to natural gas, which increased by
almost the exact same amount (217 terrawatt-hours) as coal declined (216 TWh),
according to new annual numbers released by the US Energy Information
Administration.
Wind electricity increased as well
— by about one-tenth (20.5 TWh) as much as gas. Solar increased a little more
than one-hundredth as much as gas (2.5 TWh).
The figures come at a time when
renewable energy advocates have claimed that wind and solar have been
responsible for the big declines in coal — claims that do not stand up to
scrutiny, according to a new Breakthrough Institute analysis.
Indeed, the new numbers highlight
the key difference between gas and solar and wind. Where taxpayers subsidized
unconventional gas exploration from 1980 to 2002 to the tune of $10 billion,
natural gas in recent years has been replacing coal without subsidies.
Wind and solar, by contrast, remain
almost wholly dependent on public support. Uncertainty last year over whether
Congress would renew the key wind subsidy meant that less than half as much new
wind will be installed in 2013 as was installed in 2012.
Where the problem for wind has been
its high cost, the problem for gas is that it has become too cheap. Natural gas
production slowed last year in the face of unprofitably low prices caused by
overproduction. . . .

On the subsequent comment thread, a pungent expression of
doubt from Wilmot McCutchen:
Pundits who are now dancing on the
grave of coal need to look at the steep depletion of fracked gas wells and the
growing public awareness of the danger they pose to the water supply. What else can replace coal? Nuclear is paralyzed by radiation fears and a
history of cost overruns. Hydro is maxed
out. Boutique solutions like wind,
solar, and biofuels are not scalable to utility scale baseload generation. So does anyone have a plan for reviving coal
and mitigating its pollution?
As against the "new abolitionism," this represents a new realism.
