Every year people die during the cold and storms of winter because of lack of preparation. Motorists get stuck in blizzards and succumb to the cold when their fuel runs out and old people freeze when their furnace stops working during a power outage. These kinds of deaths will be much more prevalent if war and/or an EMP strike brings down the national power grid for a time (a few months if we’re lucky, a year if the establishment doesn’t get their act together).
For survival situations, you have to consider if your main or backup heating systems are going to operate when the utilities are down. Stored fuels like oil, propane and coal are fine while they last, but these furnaces require some electricity to control and run the fan. Renewable resources like wood are limited as well for those who don’t live near a dense, wooded forest. Fortunately, most wood stoves don’t need any electricity. But ultimately, everyone ought to be prepared to survive without external heat.
A Better Way to Stay Warm:
To survive in the cold focus on keeping your body warm—not the space around you. Modern long underwear is thin and comfortable and will keep you warm down to 40 or 50 degrees depending on your activity and other outer layers. Even cotton works if kept dry, but when it gets wet it loses loft and keeps the water close to your skin drawing out heat and making you clammy and cold (this is why survivalists say “cotton kills”). Long wool underwear is still the best of nature’s fabric—especially if you’re moving a lot and perspiring. Wool retains some loft and the new Merino blends aren’t itchy and are machine washable as well.
