The problem is not when you have four tires filled with air on your vehicle, it’s when you have a flat tire. And that was Alberta’s power grid at 6:51 p.m. on Friday, as wind power generation fell to 7 megawatts out of a possible 3,618 megawatts.
And if you’re counting flats, out of the 36 wind farms in Alberta, at that moment, 32 were producing precisely zero power.
