Here in Alaska, I use a 2,000 watt Honda. It will not run the whole house, but my furnace can be unplugged and it will run it. You can also put a couple lights on it. JUST DO NOT HOOK ANYTHING UP TO YOUR HOUSE WIRING,it can fry the linemen working on the power supply!!!
Here in Wyoming I have a 12,000W propane powered back-up generator that automatically starts up and switches over when the power drops out. The transition takes a couple seconds and is virtually transparent, and I can run my normal household load off of it. Heck, sometimes I don’t even know the power has been disrupted until I look down the hill and notice the town has gone dark!
My daughter and son-in-law live in Atlanta and went on Facebook and found a stranded motorist within a mile of their house. They went out and met her and let her spend the night with them. They did not know her, but felt the need to help out. I am so proud of them.
The day of the storm, Home Depot online has a sale on propane powered generators. I bought one that day.
