Just like the motor car destroyed the economy by putting all the blacksmiths, cart makers and farriers out of business.
You are correct, it didn’t. There was a very gradual transition over much more than 10 years, with horses only being eliminated as a common method of transportation when cars became more economical. No government fiat was required, and the economy had time to adjust.
Maybe electric cars will one day replace the internal combustion engine, but they aren’t ready to do so now.
Moving to a non-fossil fuel based economy just means retraining people to do the jobs that will be needed creating the new technologies that will run the new economy.
This is delusional. Only a small fraction of the population is capable of creating new technologies, and they’re largely doing that already. And fossil fuels have inherent advantages that we aren’t even close to replicating with alternatives.
In a lot of cases factories can be retooled and workers retrained very quickly because the new tech is very similar to the older, in other cases it might require a lot of retraining, but that's how the world works.
No, that is not how it works. Not even close. Factory worker training isn’t the problem. Retooling is a bigger deal that you seem to appreciate, and what exactly do you think they will be retooling for?
The energy industries such as BP, Exxon-Mobil, Shell, and others have been preparing to switch to more green tech for over a decade. Doing so won't hit them as hard as you might believe.
Yeah, no. They have been preparing to make “green” energy a bigger part of their portfolio. None of them are prepared to stop using fossil fuels. And the problem isn’t what happens to them, the problem is what happens to their customers. Green energy can not satisfy the economy’s need for energy.
Likewise car manufacturers have been moving towards EV's.
Which are too expensive, suffer range limits, and require fossil fuels to charge them. Our electric grid cannot provide enough electricity to charge our cars if everyone switched, and that’s with keeping fossil fuel plants, AND ignoring whether we can get enough lithium, cobalt, and rare earth metals to produce all those electric vehicles. They are a niche product, and will be for some time.
Appliance manufacturers have been making more efficiency appliances.
Exactly: they are already doing that. No green new deal required. And there aren’t a lot more gains to be had without degrading performance, which is already a problem.
