Maybe you should get solar panels. Even if you are lacking in sun now, you can store up energy during the summer and then save that for if you get an outage in the winter. Also, even a little bit of energy might be enough to power a Pyra, so maybe your winters do have enough sun.
If you only need to charge your Pyra, or mobile phone, you could use a portable solar panel pack. But usually you would survive a planned power outage as they are temporary.
For using electricity to heat your house and power appliances you need more power. Solar panels or wind energy could work here, depending if that works in your area.
Solar panels don't work if they are covered by snow (you could obviously put them in a spot where they are cleaned easily)
If you live in these regions it's a good idea to have multiple alternative sources of power. Easiest is probably a diesel generator, as fuel is usually available in the US.
Cooling and heating can be done with a heat-pump (like an air-conditioner), heating does work a bit limited under freezing temperatures to. Which is still way more efficient compared to electrical heaters.
You could also heat your house based on gas, probably other fuels work to, but that also depends on your living conditions and availability of these fuels.
Other options are to locally heat some parts of your house, with IR panels for example. Or you could have electrical blankets for example.
Problems during extreme cold could be frozen and broken water pipes, which will cause additional issues when they unfreeze.
Most people in the US don't rely on water for drinking via those pipes I would assume.
