The SMH reports:
Against all expectations, US emissions of carbon dioxide into the atmosphere, since peaking in 2007, have fallen by 12 per cent as of 2012, back to 1995 levels. The primary reason, in a word, is “fracking”. Or, in 11 words: horizontal drilling and hydraulic fracturing to recover deposits of shale gas.
Yet the Greens wanted it banned here. This is the difference between being pro-environment (which many people are) and anti-science (which the Greens often are).
One can virtually prove that shale gas has been the major influence driving the fall in US emissions. Just ten years ago, the natural-gas industry was so sure that domestic production was reaching its limit that it made large investments in terminals to import liquefied natural gas (LNG). Yet fracking has increased supply so rapidly that these facilities are now being converted to export LNG.
Natural gas emits only half as much CO2 as coal, and occupies a rapidly increasing share of electricity generation – up 37 per cent since 2007, while coal’s share has plummeted by 25 per cent. Indeed, natural gas has drawn close to coal as the number one source of US power.
Half the emissions of coal? If the Greens honestly thought climate change was the planet’s biggest threat, they’d be promoting fracking.
