No, the Tesla Model S Doesn't Pollute More Than an SUV 559

thecarchik writes "In an exhaustive 6,500-word article on the financial website Seeking Alpha, analyst Nathan Weiss lays out a case that the latest Tesla Model S actually has higher effective emissions than most large SUVs of both the greenhouse gas carbon dioxide and smog-producing pollutants like sulfur dioxide. This is absolutely false. Virtually all electric car advocates agree that when toting up the environmental pros and cons of electric cars, it's only fair to include powerplant emissions. When this has been done previously, the numbers have still favored electric cars. The Union of Concerned Scientists, for example, concluded in a 2012 report (PDF), 'Electric vehicles charged on the power grid have lower global warming emissions than the average gasoline-based vehicle sold today.' Working through every one of Weiss' conclusions may show a higher emissions rate than Tesla's published numbers, but in no way does a Model S pollute the amounts even close to an SUV."

      A Prius is so efficient that you can't even feel yourself pressing the gas pedal, unfortunately the speedometer doesn't either.

        I drive a 2010 Prius. The power is quite acceptable. I actually spun my wheels the other day on wet roads when starting hard from a light. I am able to accelerate safely on freeways, and I can easily cruise at 85 mph if I want (though the fuel economy obviously drops). The other day, I gave the accelerator a kick to get across a changing yellow, and the acceleration was quite good.

        The main thing you have to get used to in a Prius is that the engine speed is dependent almost completely on how hard you press the accelerator, and not on how fast the wheels are spinning. This means that you don't get that same increasing engine pitch on accelerating that you do on cars without a continuously variable transmission. This might give some the impression that acceleration isn't taking place, until you look at your speedometer and realize you are going quite fast. I have gotten used to it now, and it seems natural to me.

        The main thing that sold me on the Prius, apart from the fuel economy (which has been 50+mpg by the way) is the durability. I spoke with a cab driver in my area who drove his 2008 Prius for 500000 miles without any significant problems...only brakes and similar things. No new battery. No engine troubles. Nothing. He said he would still be driving it if there weren't regulations on the age of taxis in our area.

    • When the Prius first got popular the same thing was said about it. Was soon proved false.

      Indeed. The massive environmental impact of the battery pack was part of that criticism, but this is also where electric cars win, if one is being honest about the numbers and don't have a anti-electric car axe to grind: The NiMH battery pack of early hybrids is pretty much 100% recyclable. Li-ion and Li-po etc isn't properly 100% recycled at the moment but that's a infrastructure problem - theoretically 100% recyclable. (I would imagine some years down the track used battery packs would be quite valuable s

    • When the Prius first got popular the same thing was said about it. Was soon proved false.

      Now that everyone has finishes wanking on about which car is the fastest, I feel there are some relevant points here that are often ignored or misunderstood. Firstly this was not proved false about the Prius. In New Zealand Toyota was taken to court and lost a false advertising suit because of their emissions claims. Not because the emissions of the power stations were not taken into account, but because their tail pipe emission figures were much higher than they claimed.

    One should think about those two questions for a moment before saying that the Tesla pollutes more than an SUV.

    • The answer to both is yes. At least in a few years, for the gas SUV, economically enough. Speaking as someone in the biorenewables industry. So this is not a particularly strong line of argument. For now, the Tesla wins hands down.

      Good point. In my area, you can pay a small surcharge to ensure that all the electricity the power company purchases on your behalf comes from renewable resources like wind, solar, and hydro. I pay said surcharge, so my Model S will be eco-magically-delicious.

      The whole argument is silly anyway. All that matters to most people is how much it costs to operate and expense to purchase. Once you add it all up it's too expensive to operate EVs. I like the idea but the reality is that EVs are still ahead of their time. The expense of battery replacement is a real deal killer too. The only thing that would make me want one is if I could charge it at work on my employer's dime.

  • I haven't read TFA of course, but does it include the lifetime environmental impact of the battery packs? (mining through disposal) That's what usually has me skeptical of today's electric vehicles.

    Assume it is true, that electric cars produce more CO2 than non-electric cars. They are still an improvement, because now our money isn't going over to warlords and dictators in the middle east (it's popular to blame the US government for propping up dictators and bad actors in exchange for oil, but when we fill up our cars, we all do it).

    And if you want to reduce CO2 emissions, it's a two-step process. First you have to get electric cars (or other alternative), then you need to get better power plants. If one of these steps happens before the other, it doesn't make it less good.
    • now our money isn't going over to warlords and dictators in the middle east

      When we started using oil, we were producing it all domestically as well. So now we're going to convert to coal, because we have enough of it... right now...

      We could very well get stuck on coal, then a century from now, we're importing it from China because we don't have enough supply to meet electrical demand. That's more of a worst-case scenario, but it seems too many people are ignorant of the history of oil production.

      Not true. Electrical cars will not reduce CO2 emissions with a reliably measurable amount. 2-3% theoretical percentage points at most.

      then you need to get better power plants

      This is where you start. This is where you work hard, and once you have solved this, you have solved the CO2 emission problem. Nothing else really matters. Go nuclear and we're all OK. It's safe (yes, it is) and it is quite clean (except for the mines). It is not renewable though, so it is a stop-gap measure.

      There are studies that show "conservatives" here in the USA will buy CFL bulbs on their own (if they think) but as soon as you label them "green" or with other labels and slogans that have been associated as belonging to the enemy tribe, they will fuck themselves just to not have anything to do with the opposing tribe.

      If you want things to get better you have to avoid terms associated by propagandists with tribalism and negative emotions. If you want the only have your tribe benefit and feel extra smug - then you continue to use the terms even after they've been ruined by propagandists knowing that the other tribe will harm itself in it's hatred of you. Depends on what kind of person you are. Me, I'm no Christian or Buddhist so I like to load things up knowing the fools will screw themselves.

        I'm a true conservative. As such I do things that make sense to me. When I saw a CFL bulb in Lowes back in the 90's I bought one for the light in my shed. I often left the light on all night and the incandescent bulbs didn't last very long. After reading the package and seeing the projected lifetime I decided to try it. After about 6 months of surviving never being turned off I started to replace all my bulbs that burned out with CFL bulbs. I didn't do it because they were "green" but because it made sense. While I believe you are correct about many "right wingers" hating on CFL's because they are labeled green I see this behavior from lefties too. Many buy anything labeled green regardless if their is any actual valid reason to do so. Lots of people are so caught up in their obsession with political viewpoints that they lose any perspective. Just because a leftie came up with a good idea is no reason for me to reject it. By the way, that original CFL lasted 7 years.

    • If the first hybrids/electrics looked/performed like the Tesla it would have probably been a lot different story. Add in that it's be tied to the "global warming hoax" and you have polarization. ie; if you believe in global warming you should get a Prius, if not f-it.

  • The problem is that most of our electricity is produced through coal burning plants. That's a very messy form of production, and many of these plants have been grandfathered in and their owners intentionally avoid upgrading them because of the costs of 'greening up' their emissions. Coal plants belch out more radiation every few months than the entire Three Mile Island disaster. They're pumping massive amounts of CO2 into the atmosphere, way more than if the equivalent MW was produced through gas or diesel.

    • Economies of scale. A container ship is even more efficient than a train as far as emissions go.

      But only if you are trying to move as much mass as possible. I can guarantee that a car wins if your goal is to move a single person.

    • Bad to use Three Mile Island as a standard for your argument, it produced entirely negligible amounts of contamination outside the plant.

      You are somewhat incorrect about transportation, 65% of crude oil consumption by transportation is for personal vehicles in the USA

    • And if we really want to talk about the "greenest" form of transportation: Diesel turbine locomotives has every other form of transport beat by a landslide. And they've been "hybrid" since the 70s; Most of them are direct-drive electric motors and use turbines and a large bank of batteries to store juice, yet are big enough to use recombinant turbines, which are very efficient in their own right.

      ... and that's why every time I see a new electric-hybrid car come out, the only thing I can ever think is "oh, look, they hooked everything up backwards again."

      Is there any legitimate, scientific/engineering reason why hybrid cars aren't set up the same way as hybrid trains (i.e., fossil fuel engine ONLY charges batteries, electric motors turn the wheels)?

    The typical person going out of their way to get a Tesla is far more likely to have, such as in my particular case, solar power at home. At the end of the year, I get a little money back from Sempra here in SoCal, because I produced in excess (I don't store for night use, but I produce more excess during the day than what I use at night). The Tesla, in this scenario, is practically zero emissions...one should, for my particular example, only count the fixed CO2-equiv of the solar panel production and the production of the tesla itself...which is combined, most likely, far less than the CO2-equiv of the production of the SUV. That point forward, every mile burned literally does nothing other than increase that gap.

    Is it "fair" to include the power plant CO2 emissions? Sure, why not...but understand that such is a worst case scenario, and does not necessarily represent the norm. Also, note there is zero effective method for being clean with an SUV, whereas with an electric you do at least have the option of getting solar, if you don't already have it. At the very least, you can choose to pay higher electric rates by choosing to buy renewable energy (most markets allow for this option).
