— by Matt Ridley, British author and journalist. Originally titled “Gas against wind”.
Shale rock where you can see it. Deep under the earth, shale is frequently full of natural gas, which moves only slowly through the rock. Water injected under high pressure cracks the rock and releases the gas. Clean, plentiful natural gas is ideal for producing the huge amounts of electricity we depend on, since the combustion products are merely water and carbon dioxide. Natural gas is left over from the formation of the earth, or it may even be generated naturally deep in the mantle — it does not rely on fossils, for methane is plentiful on other planets.
Shale gas will save us. It has no nasty emissions like coal does, its modest wellheads sit in our landscapes much gentler than great, ugly, noisy wind turbines, it’s more abundant than oil, it’s easy to extract (with a clever new technique), it’s far cheaper than any “renewable” energy, including nuclear, it could last the world for 250 years and it beats wind and solar handsomely when the wind stops and the sun sets. What’s not to like? Here I’ve somewhat shortened Ridley’s superb summary, but his laconic style is available in full at The Rational Optimist. H/T Bob Carter.
Which would you rather have in the view from your house? A thing about the size of a domestic garage, or eight towers twice the height of Nelson’s column with blades noisily thrumming the air. Over ten years, eight wind turbines of 2.5 megawatts (working at roughly 25% capacity) roughly equal the output of an average Pennsylvania shale gas well (converted to electricity at 50% efficiency).
Let’s make the choice easier. The gas well can be hidden behind a hedge. The eight wind turbines must be on hilltops, where the wind blows. New pylons are needed; the gas well is connected by an underground pipe.
This is an adopted article.
Unpersuaded? Wind turbines kill thousands of birds of prey every year. And bats: the pressure wave from the passing blade just implodes the little creatures’ lungs. You and I can go to jail for harming bats or eagles; wind companies are immune.
Still can’t make up your mind? The wind farm requires eight tonnes of an element called neodymium, which is produced only in Inner Mongolia, by boiling ores in acid leaving lakes of radioactive tailings so toxic no creature goes near them. Continue Reading →

You might think the ETS impost on coal’s CO2 emissions, about twice those from natural gas, would give gas an edge, but you’d be wrong—rising prices for carbon credits have pushed up the gas prices too. The graph at right shows an eye-watering surge in the carbon price of about 400% over the last 11 months (although I guess 400% of nothing is still pretty small; so it could get worse). This financial punishment for the poor is a clear consequence of market interference by the climate justice do-gooders—nobody else has done this. The sooner they lose office the better, in the EU and everywhere. Continue Reading →
