About 15 years ago, I purchased an emergency generator, one large enough to power the entire house. Cost me about $400, manual start, fires up on the first pull of the starter cord. Spent another $150 to have an electrician to have the connections made to the house. This, after the passage of a hurricane put us out of electric for 4 days. Best investment I ever made. Especially that I am now on life support with an oxygen generator 24/7.
During the past few years, I have spent a lot of money on home safety equipment, including an electric stair lift chair, handicap accessible bathroom, safety rails and shower seat, electric scooter, handicap ramp for front steps, outdoor step rails, scooter transport rack for the car and two portable oxygen generators. Getting old can be a bit expensive, but in the long run, it's worth it. The items listed above can be essential to life, especially during a power failure if you happen to be dependent upon them to take that next breath.
Everyone wants to go to Heaven, but no one wants to go this afternoon.
