  1. > So if I happen to live in a country without any 120 volt grid at all, all chargers are at least Level 2 by default?

    According to the SAE standards, yes. Actual wattage may vary depending on the circuit ampacity available though.

  2. As defined by EV charging standard SAE J1772:

    Level 1: 120VAC (nominal) up to ~2KW

    Level 2: 208-240VAC (nominal) up to ~20KW

    After that you have "quick chargers" which there is multiple standards for, and all bets are off. They usually involve putting power directly into the battery, bypassing the vehicle's on-board charging hardware.

    It matters because it impacts how quickly that tipping point is reached, and how quickly the changes happen. You are wrong in your thinking; It's not as if there will be no problems until we hit 2C and BAM! we're fucked... it's a process, and if we can slow down that process it buys us more time to mitigate the problems and lessens their severity.

    In other words, to correct your car analogy we need not a cliff but another, oncoming car.

    Even if the other guy doesn't slow down, slowing down yourself will lower the severity of the crash and maybe give you an extra split second to swerve to make a head-on collision less direct.

    It should also be mentioned that reducing CO2 emissions by way of alternate technologies is actually a net positive economically, in the long term, so your argument also falls flat on that front. it only seems more expensive if you are unable or unwilling to see the economics of it beyond a few year's time.

    1) Seeping is not the same as leaking. it's absolutely possible for a hairline crack in a pipe to let contamination in without letting water out, or for some chemicals that aren't water to diffuse through the pipe itself if it has become porous.

    The way I see it, the subsidies are not really for the consumers, but for the manufacturers.

    1) Manufacturers are going to be reluctant to make a product there's no clear market for

    2) There can't be a market for a product that doesn't exist

    3) Since there's no existing production the cost to produce them is high

    4) High production cost, and therefore high sales cost, reduces market potential even more

    This is where the subsidies come in; Lowering the cost to consumers (4) helps expand the market (2) to manufacturers have incentive to produce said product (1) which in turn lowers cost of manufacture (3).

    So I'd argue that subsidies are carrots for manufacturers to take that risk. It's clear, given the popularity of Tesla, that people are willing to pay premium for a good car... but that is not necessarily enough to get larger manufacturers to risk turning away from the many billions of dollars invested in supply chains, R&D and manufacturing facilities behind ICE vehicles. Some companies even actively oppose any efforts to widen EV adoption, because that would mean they would have to take a risk (either risk in developing and marketing a new BEV or risk losing out to competitors that do - solution? Make sure nobody does!)

    > The grid is a replacement for storage when there is always demand exceeding supply

    Except this may very well be the case; As the percentage of renewable energy to the total grid supply increases, it rather quickly reaches a point where you are producing more than you are consuming, if only briefly. The only reason is doesn't happen in the US that often is a relatively low percentage of renewable energy so far, which lets the grid compensate by throttling down conventional power plants.

    But that luxury is quickly coming to an end.

    So when you say storage is "inefficient" it's a bit of a head scratcher... inefficient compared to what? If your choices are running a combined cycle gas turbine on non-renewable and carbon-emitting natural gas that costs money at 60%, or taking excess solar or wind power that's essentially free and storing it for later at an overall efficiency of at least 60% and rely even less on generation that costs you money to run.

    Or to use a home as an example, I'm getting free-to-collect energy all day when I'm not home and running the meter backwards, earning credit towards my electric bill. I'm earning maybe 8-10 cents per kilowatt-hour on credit this way. When I get home, the sun is setting but I'm using more electricity now, so I'm buying back that power at maybe 20 cents per kilowatt-hour (base fee that I was being credited for, plus taxes and fuel charges and other BS). If I had storage, I could be saving ~10 cents per kWh for the energy I was able to store and recover. That's not a waste by any definition; it might not be enough to make it economical but it's not a waste either.

    Of course not. My point is unless consumption coincides with production, "The laundromat down the street" is not getting 2kW from you, ever. The grid does not store energy (yet) in any sense; it can sink and source power, but you're just offsetting other production.

    > Is 100% of our energy solar at any point during the day?

    Not yet, no, and that's exactly my point. Because it will take a long time to transition to renewable energy that requires storage, it's okay for storage deployment to lag behind renewable deployment.

    > If it's less-efficient than the alternatives

    The grid is not an alternative to storage. They are two different things that work well together, neither being a replacement for the other.

    This has nothing to do with back-up power either. It's about taking excess energy that's abundant at one time of day (e.g. solar) and storing that excess for use later. Batteries are merely one of many options to do that. "Stocking up while it's cheap" is such a no-brainer strategy it's amazing people can't understand it with respect to energy.

    It's also entirely possible that someone might actually notice.

    Difficulty: The laundromat down the street is busiest after 5PM when your solar panels aren't producing as much. You're probably also home at that point, using more power yourself.

    Now, there is a LONG WAY TO GO before energy storage becomes necessary, but there's no reason there can't be benefits to it now. Especially for solar, where peak production does perfectly not coincide with peak consumption.

    That said I think energy storage is better handled upstream at the utility side of things, but batteries for home use are not "a huge waste" IMHO.
