In this article I’d like to talk about the life cycle analysis of a traditional car with an internal combustion engine compared to that of an electric car. I’m not actually going to perform any detailed life cycle analysis calculations, just talk about the number of additional parts that a petrol or diesel powered car requires compared to an EV.
First of all, let’s get one thing straight. No one is saying that purchasing an EV car is ‘better’ for the environment than purchasing no EV car at all (and no petrol/diesel replacement either). Right? No one is saying that here, there or anywhere.
It’s nice that David Pilling has written about where materials come from when they buy an EV. But why not also write an equally-damning column on the materials that go into petrol powered cars? Likewise, it’s nice that Schalk Cloete has written about the hidden emissions of electric cars. But do the authors really think that petrol- or diesel-engined vehicles are any less exempt? That’s what pisses me off.
There are thousands of intricate moving parts that make up a conventional internal combustion engine. Thousands. In order that they function correctly, they require complicated electrical, lubrication and cooling systems. The first time I looked at my motorbike’s repair manual, I was shocked!
Let’s talk about how many individual parts there are in an internal combustion engine and compare shall we?
What about all the pistons, piston rings, driveshafts, camshafts, gearbox, valves, crankshafts, valve springs, fuel injectors, bearings, o-rings, timing belts, fan belts, flywheels, alternators, ignition coils, spark plugs, distributor, starter motor, fasteners, sensors, switches, relays, cables, wiring harnesses, oil pumps, water pumps, fuel pump, oil filters, fuel filters, petrol tank, radiator, exhaust system …I mean the list goes on and on and on and on!
My point is that none of the above mentioned parts are required in an EV. None. I will repeat that: none.
So fossil fuel driven cars are competing with a motor that has ONE moving part in it (well except for the ball bearings on the main drive shaft). So the internal combustion engine now is potentially at a huge manufacturing and environmental disadvantage.
The cost of manufacturing, moulding and machining all of those extra parts is huge! And they’re not made of crappy alloys either. What then is the environmental cost?
What about the lead in lead/acid batteries? What about the copper in the starter motor? And what about the aluminium in the radiator? What about the aluminium in the engine block and gearbox casing? Where do all these materials come from?
What about the Manganese, Molybdenum, Chromium, Vanadium and Nickel in all those hardened-steel moving parts inside the engine and gearbox? What about the energy that goes into mining, smelting, forging, forming, cutting, swaging, extruding, casting, injection moulding, machining, tempering, hardening, plating?
What about the environmental impact of building and maintaining all of the machines used in manufacturing, processing and production? What about the energy required by all of the machines on the assembly line? What about the energy required by the testing and tooling machinery to make sure all of the parts are within tolerance?
What about consumables? What about engine oil? What about the coolant? What about the battery acid? What about the transmission fluid? What about the gaskets? What about the grease? What about the air filter? What about the oil filter? What about the fuel filter? What about the environmental cost of changing those frequently?
None of those things are required with an EV either. None.
There are so many friggin’ parts, no one has even tallied up the environmental cost of them individually (instead they work out how much energy the factory or the entire transport energy sector uses). It’s a rough guess at best.
If EV cars were invented first, piston engined car would never have even been conceived, that’s how overly-complex they are to design, manufacture and produce. Of course EV manufacturers already know all of this, that’s why they’re all trying to jump on the band wagon now, because there’s potentially more profit in it.
Can you at least begin to see that it’s not just about the environmental impact of a lithium ion battery in an electric vehicle. And that it’s not just about where the electricity comes from? It’s much more ‘complicated’ than that.
Would fossil fuel proponents now like to sit there and calculate all of the life cycle factors and environmental impacts, taking into account all of the things I have just spoken about?
The bottom line is, you have got to be fuckin’ kidding me if you think combustion engines are more sustainable when everything is taken into account… and yes I really would hate to be the sorry bastard that gets lumped with all those calculations.
