Natural Gas Versus Wind Power

Matt Ridley has a new article contemplating the future of energy from wind versus natural gas. Read it here:

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. The energy they can produce over ten years is similar: 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) in its first ten years.

Not convinced? The gas well requires no subsidy – in fact it pays a hefty tax to the government – whereas the wind turbines each cost you a substantial add-on to your electricity bill, part of which goes to the rich landowner whose land they stand on. Wind power costs three times as much as gas-fired power. Make that nine times if the wind farm is offshore. And that’s assuming the cost of decommissioning the wind farm is left to your children – few will last 25 years.

Decided yet? I forgot to mention something. If you choose the gas well, that’s it, you can have it. If you choose the wind farm, you are going to need the gas well too. That’s because when the wind does not blow you will need a back-up power station running on something more reliable. But the bloke who builds gas turbines is not happy to build one that only operates when the wind drops, so he’s now demanding a subsidy, too.

The rest of the post covers the revolution of the natural gas industry due mainly to the application of hydraulic fracturing to shale formations that was previously assumed to be infeasible. Natural gas can heat your home, provide electricity, and power your automobile. Time and time again, unforeseen technological innovations have dramatically changed industries, whereby governmental mandates of other energy sources have proven costly and ineffective (wind, biofuels, solar, etc.).
