Just how serviceable will a 2015 model electric car be 10 or 15 years down the track when that model of battery pack has long since been replaced with something else? In contrast, any reasonable workshop can keep a conventional car running for its' full useful life even if a few bits need to be improvised.
I've said the same thing myself. I finally sold off a 1950's tractor that I still used almost daily, and replaced it with a new one. Sure the air conditioned cab is great, and it steers itself whilst I listen to the iPod, but I have absolutely no doubt that it won't still be running in 50 years, and equally no doubt that the 1950's tractor, if serviced regularly, will be going strong when my new one has died.... The only thing that has almost killed that old tractor is stupid OH&S regulations!
My parents bought an electric cooker when they were married. It lasted for 30 or so years, with elements being replaced and a new clock. Then the spares became hard to get and so they had a new kitchen with a new cooker. The new cooker failed after 4 years, and failed again after 6 years at which time the parts could not be obtained so a new cooker was needed.......
The issue is not really battery vs. mains power, the issue is that parts are no made cheaply and made for one model - so when that model ceases production the parts go with it. In times past the parts were made to last until they wore out (many years) and because they were shared across many models they were produced for a long time. Long production life, long service life and commonality meant that those parts could keep machines going for a long time. These days parts are cheap plastic that will break long before they wear out. They are made in a nameless Chinese factory for a couple of weeks for a specific model, and once production has ceased it's not even worth warehousing a stockpile of parts, because
most people will replace the entire unit rather than repair it anyway!
This entire situation is very sad, and flies in the face of any global warming or sustainability nonsense. Like I said in a previous post, it's even sadder when people dispose of a perfectly good product to replace it with one that will save 5% power or water, but that will fail or be outdated long before it's embedded costs have been repaid.
But such is our nature. We currently have several trades union striking for more pay. But that's more pay for the same or less work. More for less. It's not possible, but we've lost track of that reality and expect more and better year on year. Business (which is only people after all), shareholders, employees, everyone wants to have more, better, newer, bigger.......
Talking about cheap plastic, I fitted flyscreens to all my windows just over a year ago. I have just had to replace the catches (turnbuckles, butterflies call them what you will) on all these screens because they have gone brittle in the sun, they cannot be turned without breaking and some have broken in wind. These are flyscreen catches, they will always be in the sun yet they have no UV protection at all. Worse still I cannot buy any other type of catch, so I would have to replace them all every year..... the answer was to buy a large bag of brass cabinet turnbuckles (eBay from China), and cut the end off them. Now I have brass flyscreen catches that should last a fair while! But I shouldn't have to do that, a flyscreen catch should be made to survive in the conditions in which it will be used!
