First batteries would have to be interchangeable. Second, So I have a brand new car and I pull in. The 'new' battery is pulled out, and other with 200 charge cycles is put in... Hmmm. Sounds fair? Don't think so. Not workable.
I would assume that you would not own the battery itself which could be half the value of the car. The dealer would supply the first battery (like a free fill up) and your on your way. We left the charging system up to the free market and basically no universal infrastructure which is all part of the problem IMHO. I assume having removable batteries is more difficult to design.

One reason we subsidize the oil and gas industry (in the US it is like 20 billion dollars or so a year) is to keep gas prices down. Globally is is like 7 trillion a year.

Without subsidizes would we still have a dairy industry, honey industry, cotton industry, family owned farms and so on...

At the moment EVs are not practical everywhere.

Regarding solar energy, a sobering statistic - On average throughout the world every un-shaded square meter receives roughly the energy equivalent of at least a 55 gallon drum of crude each year, whether you use , convert, store, or do nothing with it.

In 1975 the price per watt produced by photovoltaic cells was roughly $90.00 USD. In 2018 it was $0.20 per watt. It's even lower in 2024. Since the average lifespan of photovoltaic panels is around 30 years, and the break even point at $0.20/watt is around 5-7 years, you make a substantial profit on your investment for over 20 years.

It would seem that unless you live in a forest, or have oil wells and a gasoline plant on your land, it seems a smart move to go electric. Biofuels aren't a bad choice but can't ummm hold a candle to the current and evolving state of photovoltaics. Nuclear will only increase the availability and further lower the price of electrical power.

Fossil fuels won't disappear maybe ever, especially if electricity production is left to sustainable means of production, but really petrochemicals are far more important. As some wise Arab once noted, "Oil is too valuable to burn".

Why by fossil fuels of course! Fossil fuel use for electricity or vehicles will not go away anytime soon I think.
Good idea to have green energy car made of Nuclear Plant Electricity.
You waste all Uranium into the ocean.

We will have bigger wales, even, and more shinning :green: into oceans

Yeah lets screw the planet even more. Go head with nuclear powered transportation.

C'mon, shortarcflyer, if you choose to be part of the discussion how can you expect any consideration or respect when you judge commercial, $30,000.00 ADULT vehicles by a $300.00 toy built for kids? How can any lesson be learned and how can anyone take your points seriously? Especially if yours was "always dead", it was either defective and should have been returned or serviced OR you should have had the battery charged back up! I have no clue what a Power Wheel's range is but I'm willing to bet it was FAR less than 300-400 miles on average on one charge, 'cuz that's what Teslas get.

I agree that you can not compare a 12 VDC toy to a 320 volt system with a motor that can output 375 kW @720 Nm (Tesla model S).

65% of US drivers live within 2 miles of a public charging station NOW. Most of those stations charge from solar. More are being installed daily.

A Washington Post article headlines results of a poll showing US drivers are losing confidence in EV based upon sales, ignoring that sales of OTHER vehicles had gone down by the same percentage.

EV sales are still increasing in California as of last month.

Several countries are mandating that all new consumer vehicles must be EV either now or in the next few years.

US Automakers find it easier to meet Federal and State mileage standards the more EV they build. Unions approve of the additional good jobs created and are supporting more EV production.

IT is happening. No matter what you think about it, it is happening. And it is a good thing.

And the fbi said, "We are the fbi, we are here to help you". Yeah, right.

California has always been on the fringe of pure insanity. I guess that explains the recent mass exodus of so many people to elsewhere.

What? Are the FBI offices getting electric cars? I know the Post Office is!

As Sec Pete said building a public charging network is difficult. The federal program might be getting a slow start but they are still being built with Tesla having the most available. Eventually Tesla superchargers will be available to Ford and other EV manufacturers.

Forgive me if this has been mentioned in this thread...

When a car (with combustion engine) needs a new engine, it's common to get a rebuilt/junkyard engine. It can usually be cost effective so replacing the whole vehicle isn't necessary.

What about fully electric vehicles? What happens when the electric motors die? Or the batteries die? Supposedly the batteries are 90% recyclable, so they probably aren't (or shouldn't) be found in a junkyard when you need replacements. Will replacing them be cost effective? Or will EVs be like Apple products, where the cost of replacing parts is almost as much as replacing the whole thing?

According to consumer reports:

"The cost can be between $5,000 and $15,000 and is akin to an engine or transmission replacement in a gas car."

EV batteries are lithium ion just like your mobile phone or laptop and degrade over time versus just failing. I expect to spend 15,000 to 20,000 for a new battery if it is still available for my vehicle but depends on if it is practical to replace or invest the money in a new car. I would expect the motor to last for the life of the vehicle.
