I would guess the more you extend the comparison the worse it gets for combustion cars. Most people get their electricity from natural gas plants delivered through a pipeline, and there is a future prospect to shift this to more renewables. Oil is pumped and delivered to a refinery, then the gas is put on a truck, and delivered to a gas station. All these things require either electricity or gas to run.

I wasn't suggesting to extend the comparison. I was saying that for the comparison done they were ignoring the environmental impact of driving the EV. Obviously EV comes out on top over a very long period of time. I'm just suggesting that period of time is longer than suggested by the parent. Personally I'd love to buy an EV but in our climate battery life is reduced by 30%, renewables are a low portion of our electr…

Just for the record- it only takes about 21k miles of driving (a year or two for most people) to release as much CO2 as the production of the battery for a long range Tesla Model 3. The standard range Model 3 comes in just under 16k miles. It seems to me like most people expect more. Also, I don't think EV prices have really changed that much. Chip shortages haven't really affected it. High gas prices and inflation a…

Does this assume the electricity is emission free? Because where I live less than 40% of our electricity is from renewables (even those aren't completely 0 carbon impact, as they have to produce panels/wind mills/etc...). The rest is from oil & gas plants. I understand you are comparing driving an ICE vehicle vs. production of an electric one. But it seems a little misleading to ignore the co2 impact of driving the e…

I'm in a slightly different situation --my 2003 Ford Focus Mk1 is still puttering along very nicely with no major issues. I am only doing about 10k miles per year but I need 400 miles autonomy! For me the best next move is to wait for the car to give up the ghost in the road --just hoping I do not become a ghost inside it!

You need 400 miles of range on a charge, even if fast chargers are frequent and available and could give you a useful charge in ~10-15 minutes?

As a Canadian who's currently driving a 9 year old Mazda 3, I'm waiting for the day it decides to call quits so I can move to an EV (9 isn't that old, so I'm hopeful at least another 2-3 years) That said, I wish there was a site that simply told me now's the right time to buy an EV. With supply chain issues, long waits for a new car, government rebates, and the influx of new inventory/models, it's hard to keep up whe…

Right now probably isn't because the car market is insane with dealers getting away with markups above sticker price because the market is so hot. Otherwise the tech seems to mostly be there the biggest issue is charging networks on longer trips. I've watched a few different videos that highlighted that other companies that rely on charging networks instead of going DIY like Tesla has have some issues with finding ch…

For the co2 equivalency analysis you really need to compare the total GHG byproduct of the production of each entire car and their fuels. The EV has a battery which is energy intensive to produce, but some of that would also be required to build and engine/transmission etc. and extracting oil and turning it into gasoline and delivering it has GHG byproducts, as well as producing and delivering electricity.

Union of Concerned Scientists still did the most in-depth analysis I've seen, and they agree with the ~6mo-18mo time period to offset the more-intensive manufacturing. And it's so old now that I think you can assume the transition to cleaner grids has progressed further in some cases. https://www.ucsusa.org/resources/cleaner-cars-cradle-grave
