Imagine enduring these temperatures when you have no electricity because the weather front has idled a large portion of the wind farms and snow, clouds and night have shut down the solar arrays and heating with oil or natural gas has been banned.
Mountain View, California just BANNED all new natural gas hookups! In CA where the power gets shut off regularly. Its obviously not as cold as the mountain north, but it does get down to 25-30 in winter for a few weeks every winter.
