We know it is expensive and unreliable.
But a
new study from the Heritage Foundation also shows that wind
power could be more dangerous to worker safety than traditional
energy sources. The tragic explosions in Massey’s Upper Big Branch
coal mine and the Deepwater Horizon drilling rig have very
appropriately focused attention on workplace hazards. But it would
be a mistake to presume that switching away from fossil fuels to
renewable energy would reduce fatalities, David Kreutzer, a senior
policy analyst in energy economics and climate change explains.
It is important to understand that the current low number of
total deaths in the wind-power industry is largely a result of the
very low amount of power generated by wind, Kreutzer points out in
his study. To properly project the potential consequences of
switching to wind from coal, it is necessary to calculate the
mortality rate per megawatt-hour.
“On a million-megawatt-hour basis, the wind-energy industry has
averaged 0.0220 deaths compared with 0.0147 for coal over the years
2003-2008,” the study says. “Even adding coal’s share of
fatalities in the power-generation industry, which brings the rate
up to 0.0164, still leaves wind power with a 34 percent higher
mortality rate. For the record, the workplace fatality rate
for wind also exceeds that for oil and gas on an equivalent-energy
basis.”
The 20 percent renewable energy standard included as part of the
Waxman-Markey cap and trade bill would require swapping about 800
million megawatt-hours of coal generated with current with 800
million megawatt-hours of wind power, Kreutzer notes. The end
result here gives good reason for pause.
“Using the recent mortality rates as a guide, we would expect
there to be 4-5 more workplace fatalities per year than if there
were no wind power at all,” he wrote. “Even this comparison
ignores the fatalities we could expect from the additional power
lines needed for so much remote wind power.”
Kreutzer’s study calls attention to an unexplored dimension of
the energy debate. The Obama Administration’s pursuit of so-called
renewable energy could have unexpected and highly damaging
consequences over time.
