I see maybe one long duration outage (half a day?) a year that requires tending to the refrigerator. It never lasts too long, minutes not days. Not enough to fund a generator. If you ever go camping it is easier than that.
Lots of generators get sold around here (hurricanes are intermittent visitors), but I think it is the human tendency to pay attention to the negative, and fearmongering by the vendors. If I ever decide to get a gen set it will be a used one at a time when hurricanes seem not much trouble. So far (25 years) I have no seen any need. The joys of underground service, and mostly tree clear, easily repaired distribution. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Sun, Jul 14, 2019 at 8:51 PM paul dove via EV <ev@lists.evdl.org> wrote: > One thing I haven’t seen mentioned is power outage.
