My position on Electric Cars

I did my masters research in Environmental Science, my focus was on sustainable development and I believe strongly in the viewpoints of Ecological Modernisation.

So that being said I have nothing against Electric Cars (EC) per se.

Modernisation should be undertaken in a stepwise manner which is consistent with Sustainable Development. I do not see evidence that the EC industry is sustainable, but it is quite happy to ride a wave of public sentiment which is essentially based on the idea that it is a panacea for climate change. It is not. Instead we see Government "picking a winner" (that'd be EC's) and pushing that agenda. This is a bad idea.

What I am against is what I see as the following list problems.

Why do it?

Well first there is the idea you're saving the planet with reduced CO2 emissions, lets work an example.


In a recent test on the Mini SE (electric) it used about 32kWh to cover 190km. This is about 17kWh/100km which is pretty typical. However if you charged that in Queensland apparently that results in about 26kg of CO2 (according to this site  https://www.powershop.com.au/carbon-calculator/).  

Now if you drove the regular Mini (based on its claims) it will use 11 liters of fuel which is about 2.4kg of CO2 per liter or 26.4kg of CO2

"I just shit my pants" (laughing), because you just spent $10,000 dollars more to virtue signal on something that does not achieve the objectives you imagined it would. Does that make you a fool or a zealot?

Motivation of Governments should always be viewed with scepticism (see this older post), as should the motivations of industry. When I see things such as the following I find it hard to not be sceptical about the actual motivations.


Such things in the points as diesel cars, curiously touted by governments and backed by fuel price advantages previously, are now bad news; this in a matter of a few years. I understood that the incentives to get into a diesel car are now dwindling ... will that happen to ECs? Well yes, we already are seeing that in places that began adopting them.

While arguments are made for the reduction in "tail pipe" emissions from cars in cities the drive to replace hydrobarbon based conversion of energy into motion in the car to only storage of electricity in the car is not backed up by similar clear spending on generation sources and transmission sources of  electricity.

Its well understood that most generation is not without pollution (even CO2) and the best studies have shown that its at best about 30% reduction of CO2 depending where you live and how your electricity is generated. Yet we do not see a proliferation of ECs in the lower power demands, we instead see them in the higher power demand areas. Tesla leading the charge and BMW and others coming on board.


The prices are certainly not something the average person is going to afford, with them being priced in the order of over AU$100,000.


Top Down Driven:

Meaning that in the "top price tier" there isn't so much of a difference between the xDrive and the older X5 BMW, but for "people's cars" the bill is very high. This is not news to me, as my recent comparison of "like for like" EV vs regular (now called) ICE cars shows you pay more than double (nearly 3 times) down at the lower end for the same thing. 

There is no mention anywhere of how many kW hours per 100km these BMW's consume. Which is even something that the average person (the one expected to make decisions) barely understands. Even when it comes to liters per 100km in their car ICE car. 

For reference my eScooter consumes less than 2kWh per 100km and the most generous figures you can expect from an Electric Car is more than 10 times that, but that comes with the issues of recharging (soon).

Fairly clearly these Electric Cars are not aimed at the masses (even the Hyundai EV, for who on the low end can afford 3 times the price for a basic car), nor it seems aimed at doing anything more about reducing CO2 than virtue signalling. Remember, electricity often depends on stuff which generates CO2.

However it goes deeper in my view, because the central (yet to be solved) issue is the cars battery pack. Currently this is Lithium, which while itself abundant currently relies on elements which are certainly not, NOR is there a certain supply of it (places such as the Democratic Republic of Congo and China being the world top two suppliers).  Lets side step the supply and ethical issues involved right there, but expect wars over this. Just like wars are over petroleum right now.

Its commonly touted that battery prices are falling (but ignored that the battery packs in cars are requiring more and more battery), with even reputable institutions putting out "public fluff" in blog posts selling the idea that  lithium batteries are getting cheaper.



I personally love the projection into the future ... suggesting it will continue falling, but their point of "look out, auto industry" is perhaps the storm that will drive prices UP not down.  Its quite certain that there is not enough battery being made (probably in any short time being able to be made) to supply the volume of batteries the ECs (which apparently we all need) will require. 

Fun Fact:

Did you know that while your laptop has maybe 3 lithium cells in it, my scooter 78 that a Tesla has over 7000? So if we consider the battery an essentially non recyclable component, and indeed a representing a scarce resource its important to make good use of it. We can make 100 eScooters per Tesla just on batteries alone ... so which would make more impact for reducing emissions? Tesla on the road or 100 more people in (say) London using an eScooter for last mile?

Yep. We are going to need a LOT of batteries. I read recently that a major Italian conglomerate is stepping into the ring:


which may sound encouraging but will this actually reduce prices or will a massive demand increase drive the price higher? 2Giga-Watt hour ... it seems a big number, but how many EC's is that? Assuming that an "average" EC needs a 50kWh battery that's about 40 Thousand cars. Currently the EU buys about 1 Million  cars a year ... so thats enough to give 4% of new car sales. Piffle innit.

Perhaps they are only in there because of government distortion of the market?

What do I mean? Well apparently Europe has now decided that even Hybrids are not sufficient to satisfy their regulatory requirements


which pretty much leaves EC's which means more battery sales and probably because of demand higher prices for the makers (who are already in a tight margins game).

What is Power

So, if we have an Electric Car we have to charge it right?

The power needed needed by EC's is best understood in Watt hours ... like if you run a bulb for an hour, or a car for an hour you need Watt hours. Most people (or so it seems) do not understand their power bill, so lets have a little look at mine:

So last month I used 168 kWh, if I'd had an EC and was charging it at home, and lets say it was one of the better EC's that uses 17kWh/100km and I did 20km per day (getting to and from work)  that's 100km or 17kWh per week (just to and from work) that's about 70kWh per month. That's a lot less than the average distance driven per week, which is much closer to 260km per week or about 176kWh per month, meaning double my draw from the grid.

Notice I didn't talk about the money ... just the draw from the grid.

So the grid will need to account for at least something like that in order to cope with the load.

Sure, we'll do it in stages, but you know ... somebody has to pay money for all the increased power generation, all the increased grid capacity and probably this will come in the form of increased power costs (so you'll pay more for your power). Also you'll probably have to pay something in the short term because power (measured in Watts) is underlied by two factors (sorry, again the general public is going to have difficulty with this because many failed science); Amps and Volts. Indeed its simple its exactly a multiplication. 

If you are going to pull 1000Watts (that's 1kW) from the grid then (assuming you have 240Volt power as Australia, Europe and the UK do; but America doesn't) you'll have to pull about 4 amps. For every 1Kw you want you'll need to add another 4 amps.

If your battery (like the BMW is 77kWh; go back up and check) and you want to charge it in 10 hours you'll need to pull 7.7kW from the grid for those 10 hours. This equates to about 30amps ... 

So?

Well the average house is wired to cope with pulling about 80 amps from the grid, so I hope you aren't using your AC or Electric Heater, Boiler or other electrical appliances because if you are you'll trip a fuse that's INTO your house and you'll be "off grid"

Clearly unless of course we get some magic solution we will be setting ourselves up for problems.

So back to Sustainable Development to me

  1. none of this seems sustainable ecologically
  2. it does not work economically for the masses
  3. it is a lot of effort for a smaller return, perhaps even a negative return when all the adaptations are counted in.

Alternatives?

To me the Sustainable Development is to do the following

  1. work at actually reducing your driving, get a bicycle or maybe an eBike, a  small motor-scooter (perhaps electric?) or an eScooter for those smaller trips (like getting to work). Myself I've cut my petrol consumption in half using the above.
  2. use public transport as much as possible, perhaps get a folding bike or an eScooter for the "last mile" (*as eScooters are not legal yet in some places (yes, I'm looking at you UK) then perhaps agitate for that?)
  3. try to think deeper and really grapple with the problems and the knock on effects
Friends of mine will know this is not my first post on Electric Vehicles, indeed I've had a few (see here, which will include this). Interestingly this whole thing really hasn't changed in the last ten years, as my first post on Electric Scooters was just over 10 years ago (think Vespa, not the stand up type you can take on the subway). In that post I clarified that it makes no economic sense and returns little benefit to the consumer. Nothing has changed, and all that has happend is we've clarified that without cheaper electricity that is not polluting there is little benefit to the environment then or now for EC's.

Indeed if batteries are wasted (like the 10 year old Nissan Leaf rotting up my street) then the advantages of an EC are quickly negative. I fear that in the hands of "the general public" (because right now its only enthusiasts) we'll see lots more "lost resources" with people stuffing up their EC's by misoperation and general neglect.

Its a path we need to consider carefully before rushing into. Ecological Modernisation isn't just about what technology Society uses, its about how Society thinks and operates ... this isn't just about consuming, about buying more (but Tesla and BMW would love you to think it does), it means you need to engage, you need to understand and you need to act!


because in reality we are fighting for our childrens lives (so make sure you understand the basics).

Thank you for looking at this EV scam (yes, I like to call it that) and giving us some tangible numbers that hipsters are never willing to face. As for governments, I remain firmly of the opinion that, in this case, are simply puppets of the car manufacturers.
