Comment on Parking isn't as important for restaurants as the owners think it is
Salvo@aussie.zone 1 year agoDepends a lot on the car.
Keeping a HSV Avalanche on the road as your primary vehicle so that you do not have to buy a newer car is probably not a fiscally or environmentally responsible choice. Nor is replacing it with a Rivian or Lightning.
Maybe a Suzuki Swift or a Nissan Leaf would be a better choice.

Alright using your examples which seem awfully chery picked the break even point of co2 in terms of years being as generouse to the suzuki as possible is about 4.16 years. Depending on age the average time someone keeps a car is 6-10 years (older people tending to keep it longer) that means about half the lifespan of ur suzuki must be spent before u break even on carbon cost. If u do the same calculation for electric vehicles u find they have a far longer break even period.
If u do the same calculations for my car it will take 27years to break even in terms of carbon cost.

What do you mean break-even point? A petrol car will emit CO2 to produce and drive, an electric one charged exclusively on renewables will only require CO2 to produce (which I assume will be phased out at some point). I am quite interested in these calculations

The production and recycping/disposal co2 costs are much heigher than u would expect. U cant get around these u cen reduce them but there are proccesses where u can not avoid pumping greenhouse gasses into the atmosphere (these can be handled by the enviroment if we hadnt been making more than nessasary for so long). And electric cars are very rarely charged exclusivly on renewables and even if they are u need to account for the carbon cost for the lifecycle of those renewables as well. U also need to account for energy losses cos thermodynamics is a bitch etc etc.
How i did calcs: Talking specificly about the case i was arguing for before where u already have a car. U can get estimates of co2/kg for producion and recycling of a car. Using that and the cars weight get its production and disposal costs. U have already “paid” the carbon cost of manufacture for the car u already own so u only have the operation. But if u where to buy a new car u have both the production of the new one and the disposal of the old one to account for. Add the yearly cost as ur linear factor. Both can be plotted on a graph and the intersection will be the time period where u break even.
If u also put electric cars on the plot they are actually worse than ur average petrol car (currently with our non renewable grid) cos u have all the losses from energy transformations electric car goes: chemical energy to heat energy to kinetic energy to electrical energy back to chemical energy (ur battery) to electric energy to mechanical energy opposed to a petrol car which goes chemical energy to heat energy to mechanical energy.
An electric car run purly on renewables might have a lower co2 cost but lithium mining is disasterouse for the enviroment. And cobalt mining is power by slavery. Its a fucking disaster all round and at this point the option with the lowest cost to humanity is looking like sacricing millions or poor people to the greater good untill we have enough rare earth minerals to have a proper recycling lifecycle. Its like the early days of aluminium extrordinarily expensive and bad to produce but once produced very easy to recycle.

So what’s the solution then? You said you like your car so I guess we can’t do away with that.
