Seems like, depending on age, it would be possible to get #4. Transportation costs down. Cars would go from 2 or 1 to zero, so car maintenance, fuel & insurance go down or go away. With online grocery, and/or online orders via WalMart, Target, Amazon, it would be possible to reduce trips to the grocery store(s) for food and other stuff
Even then, the rates that utilities charge all customers will continue to increase annually. That’s why Bender notes that [installing solar panels](Is It Time to Switch to Solar Power?) with batteries can reduce rising electricity bills.
I did that (install solar panels with batteries) early last December, so I can give some feedback
First, as I am on true met metering and a rate that does not vary by time of day, the batteries provide no financial advantage except whatever comes from providing backup in a power outage. Those with different circumstances may benefit financially, but I do not. Rather I am paying off the cost of the battery system (two Tesla Powerwalls) without it saving me a cent.
Second, while my last power bill was zero, and I many well finish 2023 with a surplus, my payments on the loan are pretty high. It might well take me the full ten years of the loan to break even, despite the 1% interest rate. All in all, while I love my solar system and am glad I chose to install it, for me it does not provide the savings the article hypothesizes.
@RHinCT - The list itself is not bad. It is a useful starting point. But, there are counterpoints to some of the issues.
For instance, the elephant-in-the-room, i.e. medical care, does have a partial solution that requires some planning and research. Medical tourism, or going overseas, to get treatment for a procedure that might cost 5X - 10X the price in the US. One could actually kill two birds with one stone - medical care and travel/vacation on one trip, and save money too. Not saying there aren’t other associated risks, But certainly, a retiree could significantly reduce some expenses.
I might have added Hobbies. With more free time there is a wonderful opportunity to pursue activities that were not possible before… boating, fishing, photography, woodworking, and so many other things that involve a bit of investment in equipment.
