A bit of diesel for my sub-compact tractor, gasoline, two stroke oil, bar and chain oil. Probably cost $50-60.00 for a Winter's worth of heat.
Meanwhile my ex-wife never got around to filling her propane tank, recently spent over $100 for space heaters and plans to buy one more big one. Electric will probably be $100/mth more running them. In sub-zero temps in an older mobile home, space heaters aren't going to do much. We get a lot of ice here in the Ozarks and if we get enough, it snaps trees and powerlines.
Can lose power for a couple of weeks.
