Generators

Things are beginning to look ugly in Northern Europe:

Britons are arming themselves with everything from generators to thermal underwear as they brace for rolling blackouts caused by the broader energy crisis in Europe.

At least I have a small generator to keep some equipment running (see the comments), and a trailer with propane if there are really bad times.

One thing I'll say about humans, we don't like being cold.  Cold kills a lot more people each year than heat does.
