It is helpful that the author quantified some of the issues, however there are many factors involved:
* Does the authors CO2 estimates for battery production actually include "mining" or just "assembly"? From reading it, it seems to just include assembly of final components into a battery.
* Moving tons of rare-earth minerals from Point A to Point B for battery production requires yet more CO2 output.
* Wind + Solar still requires massive batteries somewhere, which still requires massive mining operations.
Further, with $40 shale oil now a reality, its getting harder to make the economic case.
- brohee 8y agoWhich rare earth are you talking about, and in which quantity?
- _red 8y agoThose who really care about the environment, know that reuse and recycling are the best approaches. So, you could buy a 15-yr old Toyota or Hyundai, since that carbon footprint already exist. You shouldn't be needlessly creating more deadly CO2. Further, in terms of energy density: solar, wind, coal, natural gas all pack far less joules per gram than petroleum. These are inconvenient truths that unfortunately conflict with the slick marketing messages of your luxury golf cart salesman.
