It highly depends on the energy mix of your country, but some countries may actually be in for a difficult winter.

You can store energy of course and even hoard it which increases the problem. Here in Poland first there were 2 week lines for coal and now there is none. Pellet has gone up in price 3x. Electric price has gone up 2-3x. Gas supply is in question. The government has said to burn anything for heat you can get your hands on which means low quality coal, peat and trash. Even if I have energy, my lungs would pay the price.

Some people are running the numbers and realizing that they can temporarily move to a warm country for the price of their heating and electric bills.
