They do not need to add them more quickly because they already sell all the cars they can produce. In the US, several state legislatures (controlled by auto dealers) have prohibited car sales except through dealerships, so yes, Tesla centers are "few and far between" in some places. I am probably biased, here. I absolutely hated the dealership experience. I always felt like I was being scammed or cheated. To buy a Tesla, you go online and click on some buttons, and the car is delivered to you. No hassle, no haggle, all costs known in advance. Dealerships in the USA have been a thorn in the automakers side for years. If there is group I most detest it's the Toyota folks who control the Gulf States, Gulf States Toyota, much to the chagrin of Toyota themselves. The set up goes back a long ways when Toyota was getting going in the US and hooked up with dealers GM had kicked to the curb. I once traveled 1,200 miles to save a couple of grand and avoid that particular cartel. 2 Quote Share this post Link to post Share on other sites

I would say alot of dealers whether its a GM or Ford or Dodge will respect what the public wants and if electric cars don't come down in price folks will keep driving big SUV's with ICE engines. As long as gasoline stays range bound lower than 2.75usa$ gallon.....why not. I live in rural small town in central Illinois and did buy a Toyota Rav4 hybrid 6 months ago, it's been towed to the dealer 30 miles away because of dead battery issues twice. Wife says trade off on regular ICE please.... So a fully electric car isn't in my future anytime soon. You have me confused Ruffneck, do you mean "flat battery" or actual "dead battery" as in battery needs replacement due to failure? I thought a hybrid would solve the first problem, perhaps even the latter? Does your wife not put any gas in the tank? If she is using only the battery without putting gas in the tank, that would kill the battery very quickly according to those on this site who seem to know about lithium battery characteristics.

Of course the story's right, but there is simply no telling the hard-core EV enthusiasts this. There is no evidence that EVs will be anything more than a niche market, without serious government support. In Australia, where I live, there are no concessions at all for EVs and sales are less than 1 per cent of the market. This is about what you'd expect from well-heeled greenies in a wealthy country. In Norway, in contrast, government support mainly in road tolls and taxes foregone amounts to about half the cost of the car. As a result, and I can only point to anecdotal evidence, wealthy Norwegian families have two cars - an EV for commuting and an ICE for serious travel. Poor families have to make do with aging clunkers on which they pay taxes to subsidise the EVs of the rich but who cares about the poor, right, when there is posturing over the environment to be done. Attempts to limit the sale of new cars will all sorts of unintended effects, such as boosting the used car, restoration and renovation markets. In many countries EV policies amount to unrestrained lunacy. Mark, there is no point in having EV's here yet because we still get 75% of our electricity via coal. Give it 10 years and EV's for Australia will make sense. If you read the latest investor briefing by Origin Energy, there is a graph from the AEMO (Australian Energy Market Operator), that shows the amount of coal-fired generation over the next 20 years. It goes from 50 GW to about 8GW by 2040, in a series of downward steps as each coal station closes, starting with AGL's Liddell station in NSW in 2 years time.

There are a number of innovative companies already looking at cheaper viable alternatives than the current "buy a very expensive EV for $70K" as can be seen by the article posted on Oil Price https://oilprice.com/Energy/Energy-General/The-Electric-Car-Boom-Is-About-To-Get-Even-Hotter.html There may well be a reduction in EV sales late in this decade as we all realise we actually dont need the cost outlay of a car as we can summon one on an app in 2 minutes to take us wherever we want to go. No costly outlay, no costly repairs, no costly insurance etc we only pay for the use of a car whilst we are in it and that's all. Sound cheaper? Yeah, cheap and nasty. Utopia gives me nightmares.

You are selling the car over and over again in effect. There are already driver less taxi companies Waymo (owned by Alphabet which is owned by Google) , and Robotaxi for example In fact Tesla as you would expect have already moved ahead with their own driver less taxi https://techcrunch.com/2019/04/22/tesla-plans-to-launch-a-robotaxi-network-in-2020/?guccounter=1&guce_referrer=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8&guce_referrer_sig=AQAAAGJKCrZk0A1bxIuJC4OkAeg7etyNGI-vgT82Q7kgy3_dwKulrse4cEvShFFOKdwS29Z0eIBa739VpphrfMs0t8u_iAncWMvT4P19SSJAkzrYS396Oq6bGfpPJorPrBATGqaAsDzi5u5MyKfmbanurBXJFzzDsJjfSG-1v0RA56wo So, now you are saying that Tesla will rip more money out of consumers pockets than what the ICE car industry (including the govt thru registration and dealerships etc)? Doesn't sound cheap to me. You cannot have it both ways. Either Tesla makes lots of money coz their "service" is expensive, or they don't coz it cheap? Personally, I would like to buy a brand new Toyata Prius for $10,000 or less. That would be cheap. Unfortunately, no company, Tesla included, wants their product to be cheap. Not even Chinese or Indian businesses want that. Never again will VW produce a "bug" that is car for the masses. As I say, no country will do it.

Your thoughts? This is complicated. The "100/kWh" is at the cell or module level, I think, and is valid as part of the COGs of a car. The 1000/kWh is (probably) your calculation that a 13 kWh Tesla PowerWall costs $13,000, installed. The power company has little to do with this. It's more about the electrician's union. The power companies do force the installation to include some (possibly) overcomplicated interface equipment, I don't know what the overall cost allocation is. The PowerWall initially came into existence to absorb the excess battery production capacity of the original megafactory, which makes cells optimized for cars. Almost by definition the cell cost for a PowerWall component will be about the same as a car component, so that $13K PowerWall will have a $1300 battery inside. As of 2020-11-17, The 13.5 kWh battery-containing unit costs $7000 while the "gateway" plus installation costs $4500. https://www.solarreviews.com/blog/is-the-tesla-powerwall-the-best-solar-battery-available To bring down the cost of a home battery, you first need to increase the volumes, and then you need to shift away from a car-oriented Li-ion battery technology to a cheaper system that is not constrained by weight or volume densities. But until the volumes go up, you cannot amortize the R&D effort, and in any event the actual cells are are already only 10% of the installed cost and that percentage will continue to go down even when using the abundant car-oriented batteries. My guess: The installed home system cost will get stuck at about $10,000, but the capacity will grow as the battery cost goes down. Utility scale battery deployments will finally drive the development of really cheap cells and modules, because the volumes are higher. Once those cells are available, they will be used in home systems also. My purely uneducated guess is that sodium-ion batteries (NIB) will win out for non-vehicle use, because they use universally-available sodium and aluminum instead of harder-to-get lithium, cobalt, and copper.

Why does it cost $13,000 if EV batteries are only $100/KWH? Somebody is telling porkies and I am getting tired of it. It's just business, as to the batteries there is a simple method of cost averaging. Deep in the bowels of Telsa I'm quite sure the battery mfg is the true cash cow, they would have the ability to determine who gets what battery at what cost Automotive gets battery A for 100 Housing gets battery b for 1000 Industrial gets battery c for 100000 Is it that simple yes of course been there done that. Then one day demand for battery c becomes greater in demand than supply. So a slight adjustments towards internal costing occurs Meanwhile the battery division is reaping the rewards of success. Once tooling and manufacturing are in place, cost of size/capacity are trivial....Now selling size brings on a whole new light as we all know. What the market will bear does come to mind. 1 1 Quote Share this post Link to post Share on other sites

Why does it cost $13,000 if EV batteries are only $100/KWH? Somebody is telling porkies and I am getting tired of it. My Tesla Model Y has a 320 mile nominal range at a nominal 4.1+ mi/kWh, with a 75 kWh battery and a cost of about $50,000. The cost of the cells would be $7500 at $100/kWh. The accepted wisdom that battery cost drives the cost of the vehicle is out of date. It was true five years ago, but no longer. Tesla builds and sells high-end cars because they can. They have no reason to build cheaper cars when they can sell all the high-end cars they can produce. Tesla has about a 25% gross margin on its cars, so COGS for the model Y must be about $37,500: $7500 for batteries, $30,000 for the rest. a true mass-market cheap car would have maybe half the non-battery COGS , so $22,500 total COGS with that same 75 kWh battery, and a price of maybe $27,500 (lower gross margin). This is still not a toy town car as it still has 300 mi range. Pre-2020 Tesla Model 3s (or Model Ys) do not incorporate the same modules as a PowerWall. The PowerWall modules use the same cells as the cars, not the same modules. (a cell is about the size of a AA battery, I think). newer cars use a new cell and the newer call will probably be used by newer PowerWalls, but again in different modules. A model Y with a 75 kWh battery uses the came number of cells as about 5.5 13.5 kWh Powerwalls. 1 Quote Share this post Link to post Share on other sites

Or am I thinking too far into the future? I'm not really an expert. There are a whole mess of "solar calculators" on the web for calculating the best sun angle. Putting solar on your roof is a tradeoff. If you have the land, (like on a farm) it is probably much better to build a standalone structure for the panels and optimize everything. Cheap if at ground level, slightly more expensive if you raise it an use it as a shed or patio. The angles depend on when you expect to have max demand (both season of year and time of day). For time of day, this depends in turn on whether or not you will have a battery. The theoretical best elevation angle for a year-round average is your latitude: the sun hits the panel straight on at the equinox. The theoretical best azimuth is a little bit west of south. If, however, you consume more power in winter, you would want to tilt them steeper. If you consume more in the afternoon (and do not have big batteries) aim them more to the west. Roof: Yep, to gain the advantage of using your roof structure instead of building a new structure, the tradeofs are accepting a suboptimal angle and messing with the shingles. The traditional approach is to just live with it as you described: pain in the butt. The alternatives are a "solar roof" system (the roof tiles are little modular solar panels) or using the bid standard solar panels as the actual weather roof instead of shingles.

And if that is the case, how long do the batteries last? Or am I thinking too far into the future? Further north: less total sun, but more in summer. Yes solar in California makes a lot more sense than solar in Illinois. The computation for battery size is independent of the computation for the panels. Less insolation: buy more panels. Suboptimal angles: buy more panels. It will often make sense to pay for more panels rather than paying for the structure that provides the best angles, especially when is not a new-built house. If I owned the rented house I live in, my tradoff would be (roughtly) $20,000 for panels on the existing roof, or $10,000 for a new patio roof structure plus $10,000 for panels. About $10,000 for the battery in either case. So, it takes longer for the panels to pay off, but not the batteries. 2 Quote Share this post Link to post Share on other sites

Uvuvwevwevwe Onyetenyevwe Ugwemuhwem Osas + 96 U December 14, 2020 So far, ridesharing has done way more for the environment than electric vehicles. Any company that tries to copy Tesla's success is in for a surprise. The main reason people buy Tesla is not because Tesla cars are electric but because they are exotic. Tesla cars are arguably bad for the environment. Tesla cars are heavy and consume lots of energy due to high weight and high performance. Bicycle and motorcycle subsidies would help the environment a lot more than EV subsidies. What happened to all the ultra-efficient three-wheeled vehicles I used to see on youtube? Three-wheels is a good compromise between a motorcycle and a car. 2 Quote Share this post Link to post Share on other sites

I always felt like I was being scammed or cheated. To buy a Tesla, you go online and click on some buttons, and the car is delivered to you. No hassle, no haggle, all costs known in advance. Not in the UK it isnt If you buy a Tesla you have to go to their "service centre" and have a 30 minute instruction with a load of other buyers on how the car works. It is inconvenient as you have to pick the car up which can be a 100+ mile round trip to the nearest service centre/dealership. The after sales service is also appalling. If you buy/lease any other make of car you can have it delivered to your door, so its the opposite of your "no hassle, no haggle" scenario with Tesla. Obviously it must be a very different experience in USA. Dan I can only comment on what i actually see and that is very few Teslas on the road compared to other EV / Hybrid brands such as Toyota, BMW, Mercedes, VW etc. With a plethora of new models being launched in 2021 by the existing and importantly trusted brands I don't see them being outsold by Tesla any time soon. Also rightly or wrongly to own a badge with BMW or Mercedes is somewhat of a status symbol and therefore more desirable for the consumer. Tesla is a relatively new brand and doesnt attract the same Kudos for owning one. 1 Quote Share this post Link to post Share on other sites

Ditto for France, which gets most of it's electricity from nuclear. Both countries can slash their carbon footprint whilst killing their imports of oil. Win-win for them? Thats what I always wondered. For Britain. As they banned ice 2030. Same with Quebec... that has plenty of hydro power. I saw an article that Egyptian gov subsidized nat gas ice conversion after their big gas find.... is there not a economic and responsible way to implement green ? I feel alot of copy and paste going on. I ask about Britain since its recently coal free at times. Here in Canada solar power really can't pay off. The reason is winter. They want us to use electric heating and are imposing taxes to do it. Like 11$ carbon tax per mcf vs gas that is worth 3$ (2030 tax rate) . But you swap cars and house heating to E from FF and my 500kwh house is at 2000kwh in sept with no sun . And a roof that could mabey supply 1200kwh 100% covered and with sunny side of garage covered. So doesnt make sense. We have tons of room water and NG so a proper mix of hydro nuclear and gas should have us plenty clean and cheap. And NG vehicles would do alot also if you could find one and not get ripped on for propane or compression (filling) . 1 Quote Share this post Link to post Share on other sites

I would expect more solar power everywhere. Why pay for electricity? You get a theoretical maximum of about 3 kW per square meter of panel in the middle of a summer day, worse at any other time, That square meter will get you enough energy to go about 12 miles each hour under theoretically perfect conditions, but in reality less than 30 miles in a full day, because the panel is not perpendicular to the sun, the day is not cloudless, the panel efficiency is not at theoretical max, your parking place is in the shade, etc. Therefore, your best bet is to put ten square meters of panel on your house roof and store the energy in a house battery, then charge from that battery. Current solar panel advances are mostly in the dramatic decrease in $/W, with only a small advances in W/sq meter, Even the very most efficient (and expensive) new stuff in the labs can convert about 30% of the sunlight into electricity, and there are theoretical reasons that this will not improve or get cheaper. By contrast, the $/W is still decreasing rapidly. Up to now, this was driven by cheaper photovoltaic elements, but those elements are now such a small part of the total that new improvements will be in the electronics, economies of scale, mechanical engineering, and business models. In particular, the most spectacular recent gain was when Tesla bombed the price of a home installation by abandoning the traditional sales model (with its expensive marketing through installation companies) and went to web-based direct-to-customer sales. 1 Quote Share this post Link to post Share on other sites
