I’ve got one and I do ride but I don’t plan on giving up my combustion engine ...
Who has asked, much less told, you that you have to give up your vehicle with a combustion engine? The most I've seen is some Automakers (not the government) stating that by a date -- typically at least 10 years from now -- they'll only offer EVs as new cars (not to include heavy trucks, farm equipment, etc).
...for the less efficient electric car. Not to mention the PR con job about the electric car.
Electric Vehicles are not less efficient, they are substantially more efficient. They do require more energy to intially produce than a car with an Internal Combustion Engine (ICE) but that difference is typically "made up" in a couple of years. I will admit that there is a lot of false information out there put out by "fossil fuel alarmists" that manipulate figures like having all energy generated by coal (in the US, less than 20% of power is from coal) and other falsehood. As an example, another manipulation they use is to include the pollution generated from creating Electric power but not counting the energy (and pollution) used to refine the gasoline.
No climate alarmist wants to discuss the effects of additional power generation to charge all of those proposed electric cars.
Maybe "alarmists" don't, but as I show above, it is good to stay away from the "alarmists" on either side -- both deal more in propaganda than science. There are plenty on the climate side who talk are willing to talk about power generation. If you are interested, here is
one article that talks about it.
Then we have the high cost of replacement batteries and the disposal of old batteries.
Replacement batteries should not be an issue -- any more than engine rebuilds or transmission replacements are on an ICE vehicle. As a general rule, EV batteries should last over 300,000 miles -- the normal life of a car. They have been engineered (on any current EV -- even going back about 5 years) to last and there are EVs out there that have traveled that far without a battery replacement. There are plenty of Teslas that have been driven well over 100,000 miles and are still running on their original batteries.
Yes, there are a few that will require new batteries -- the percentage is extremely low (maybe .01%) -- due to a manufacturing defect. There have also been a couple of people who bought old EVs -- not Tesla -- who complained about needing a battery replacement a few months after buying the car used. Again, it is the difference between the older EVs (the ones that had less than 100 miles of total range) and poor battery management built in -- such as no active cooling system for the battery. Since heat destroys batteries, it is unsurprising that an EV in Florida, without an active cooling system for the battery, would need to replace the battery prematurely.
As for disposal, to this point that hasn't been a problem. Currently, most EV batteries are actually reused -- though not in cars. A lot are used by businesses for battery backup systems. Part of the trick of EV battery "failures" is that the entire battery isn't bad. Additionally, the batteries will be recycled, a few recycling "shops" are starting to come online but the issue is that there aren't enough batteries for them to recycle, particularly with the number being reused.
And, of course, this ignores that battery technology, and the recycling technology is quickly advancing. It will be interesting to see what battery technology looks like in a decade or two, particularly if solid state "batteries" are perfected.
Look at California, they cannot produce enough electricity now for the electric cars they do have much less the ones they want.
And this is false -- California has no issues with producing enough power for electric cars. Instead, what happened in California was extremely hot, record temperatures, where energy use was much higher than usual for a week. And "fossil fuel activists" falsely reported what California asked at that time -- they asked people not to charge their EVs in the evening (between 5-10) when energy usage was the highest. What is ignored is that most Californian's typically don't charge their EVs in the evening -- California utilities offer cheaper electric prices overnight (when demand is quite low), so people program their EVs to charge between 10 PM and 7 AM -- which still gives the car enough time to fully charge. So the request (it was not a mandate) did not effect most California EV owners, at all, and they did not lose power.
