Electric vehicles use a lot less energy in total in the supply chain than gasoline cars (extracting and refining and transporting oil uses a lot of energy too, some of it electricity).
So electric vehicles reduces the energy required.
Longer term: Gasoline cars are not viable at all; electric cars are viable to the extent one can secure the energy for them. It is a way of getting any road transportation done in the future AT ALL; that is surely not a con?
I hope noone is arguing that moving to electric cars by itself is sufficient to stop climate change. That would be a con but also seems like a strawman.
The goal should be net zero, and electric cars are needed to have road transportation at all.
- tcfhgj 4y agoNope, the goal must be net negative... If you dont want to end up with at least 4-8 degrees more
- tremon 4y agoAbsolutely agreed, except for one part: I don't think net zero will be enough. It might have been enough if we were at net zero thirty years ago. But now, in addition to net zero (which would be an impressive feat to achieve, society-wide), we need to work on absorbing carbon from the atmosphere, before the ocean does it for us.
- collyw 4y agoWhat won't net zero be enough for? The mythical climate change boogeyman, that's hasn't melted all the glaciers or put Manhattan underwater like we were warned of 30 years ago.The fearmongering is all based on models- and covid demonstrated how useless those are with complex systems. What's the solid evidence any of it will happen? The IPCC model is an average of other models, it has no validity by itself (just reject the carp models until it's past performance looks good). What models have had an accurate forecast and for how long? https://nypost.com/2020/01/10/the-telling-tale-of-glacier-national-parks-gone-by-2020-signs/ https://nypost.com/2020/01/10/the-telling-tale-of-glacier-na...
- tremon 4y agoWhat's the solid evidence any of it will happen? What kinds of solid evidence will you accept? Should we wait until all corals have bleached and withered away? Should we wait until all of Greenland is arable? How many years of drought should California endure until you might start accepting that maybe something has been changing for the worse? Or should we rather ignore you and focus instead on things we can change?
- collyw 4y agoThe climate has always changed. Trying to stop it is an exercise in stupidity.
- zaccusl 4y agoCan two thing not be true? 1. the climate has always changed. 2. the rate of change depends on a lot things, among them how much green house gases exist in the atmosphere. You have to have a pretty poor understanding of science to deny either one.
