This is getting tiresome.
Cheerleading for shale gas 'fracking' today, Margaret Wente
spews a number of falsehoods. For starters: “the U.S. appears to
be the only major emitter that's actually reducing emissions. Since 2006, U.S.
emissions have fallen by 7.7 per cent, according to the International Energy
Agency – despite the absence of a global carbon treaty, or stiff new
regulations, or a cap-and-trade regime”.
The “only major emitter” reducing emissions?
Well, no.
That’s not what the
International Energy Agency says: “CO2 emissions in the United States
in 2011 fell by 92 Mt, or 1.7%...CO2 emissions in the EU in 2011 were lower by
69 Mt, or 1.9%.”
As for longer term comparables, in October 2010, the Guardian
reports, “The European Environment Agency reported
that by the end of last year emissions produced by the current 27 member countries
have fallen by more than 17% since 1990, putting them "well on track"
to meet the target to meet the EU's own pledge of a 20% reduction by 2020 . The
original 15 EU member states who signed Kyoto have dropped their emissions by
6%, giving them "a headstart to reach and even over-achieve" their
target under the treaty of an 8% reduction. Emissions from the current 27
member countries have fallen by more than 17% since 1990, putting them
"well on track" to meet the target to meet the EU's own pledge of a 20%
reduction by the same date…”.
Wente: “You'd think that environmental groups
would rejoice at this great news. Instead, they've gone to war. The main reason
for the fall in greenhouse gasses is a new technology known as hydraulic
fracturing (or fracking), which they claim is a menace to the planet”.
Wrong. The International Energy Agency
in fact says that the U.S. move away from coal is
just one of several reasons for the small decrease. Others are exceptionally mild winter weather, the economic
downturn and energy efficiencies (no doubt in response to “stiff new
regulations” Wente claims played no role). According to them, the most recent
reduction is
"primarily due to ongoing switching from coal to
natural gas in power generation and an exceptionally mild winter, which reduced
the demand for space heating”. The longer term
(since 2006) reduction, “has arisen from lower oil use in the transport
sector (linked to efficiency improvements, higher oil prices and the economic
downturn which has cut vehicle miles travelled) and a substantial shift from
coal to gas in the power sector. They do not claim
that fracking or shale gas is the “main reason” for the reduction, as Wente
maintains.
And then Wente says this: “Fracking promises to unlock vast new reserves of
shale gas, which emits roughly half as much CO2 as coal, and 30 per cent less
than conventional oil”.
Wrong again.
While conventional natural gas “emits roughly half as much CO2 as coal,
and 30 per cent less than conventional oil”, this is not true of shale, which
comes with a much higher methane component.
The New York Times cites studies that "suggest that the
rush to develop the nation’s vast, unconventional sources of natural gas is
logistically impractical and likely to do more to heat up the planet than
mining and burning coal. The
problem, the studies suggest, is that planet-warming methane, the chief
component of natural gas, is escaping into the atmosphere in far larger
quantities than previously thought, with as much as 7.9 percent of it puffing
out from shale gas wells, intentionally vented or flared, or seeping from loose
pipe fittings along gas distribution lines".
And a
report
from Cornell University notes these problems with shale:
Natural gas is composed largely of methane, and 3.6%
to 7.9% of the methane from shale-gas production escapes to the atmosphere in
venting and leaks over the life-time of a well. These methane emissions are at
least 30% more than and perhaps more than twice as great as those from
conventional gas…Methane is a powerful greenhouse gas, with a global warming
potential that is far greater than that of carbon dioxide, particularly over
the time horizon of the first few decades following emission. Methane
contributes substantially to the greenhouse gas footprint of shale gas on
shorter time scales, dominating it on a 20-year time horizon. The footprint for
shale gas is greater than that for conventional gas or oil when viewed on any
time horizon, but particularly so over 20 years…
In addition, a
report in the New York Times indicates that the shale gas
boom is likely to go bust, just like Enron – with consequences not just
for the economy, but the environment.
Wente’s
nonsense appears to be original this time, rather than the borrowing so often
seen in the past (here, or just browse the archive for many
other examples), but her breathtaking NIMBYism is worth a final mention.
Content to argue for “more and
faster” when it comes to someone else’s water contamination, Wente was recently fiercely protective of her own little
bit of paradise – a country house she maintains to provide picturesque relief
from the monotony of her upscale Toronto condo (whose kitchen appliances alone,
she brags repeatedly, cost more than an
earlier house). Madame Wente’s
country estate must be kept free of all intrusions or development – no gravel
pits, limestone quarries or wind turbines nearby to disturb the weekend
tranquility or decrease property value.
But for the rest of the country folk - the ordinary people who actually
have to live year round on land whose well water may be affected – well, says
Lady Margaret, let them drink flaming water with their cake.
