Producing an EV does create higher CO2 emissions though. Not even Tesla argues against that one. It's estimated to be ~20,000 km, but can be more or less depending on your source of electricity. So between a year and two years depending on how much you drive, but could be less if you drive a lot.

Edit: Also, we have so much excess energy at night. We just need to set up and incentivize charging at night and the grid can take on a ton more.
