Dojo requires chips. And chips requires more energy. Can we actually replace fossil fuels with renewables worldwide or are we just adding renewables on top of fossil fuels?
Remember Tesla's mission, "to accelerate the world's transition to sustainable energy"? We haven't started fixing the problem, far from it:
https://www.axios.com/2018/08/16/despite-renewables-growth-there-has-never-been-energy-transition. We need renewables to reduce fossil fuel usage in aggregate. Not find new ways to consume the electricity generated by new capacity (that was created to
replace fossil fuels in the first place, not supplement it)
You can't be credible when talking about energy efficiency if you don't know about Jevons Paradox, very often called the rebound effect

Your post makes it sounds like Tesla developing Dojo, which obviously has energy requirements, is at odds with the goal of moving the world to sustainable energy. That seems like you are painting Tesla as hypocritical. Taken to its logical conclusion, that would imply that
any endeavor requiring energy usage is at odds with pursuing the goal of transitioning to sustainable energy.
That, of course, is not only not really possible, but ignores the overall equation. It took energy to build and equip the Tesla factories. It takes energy to run them, It takes energy to develop new technology, like FSD. But, if that helps make the Tesla EV's an incredibly compelling product, the eventual net impact is
reduced energy consumption as they displace ICE vehicles. And the energy that
is consumed is easily created by renewables. And along with making the vehicle compelling (thus spurring adoption), features such as FSD have the dual goals of making the cars safer thus saving lives, and allowing shared robotaxi usage, reducing the overall number of cars needed. Both of which are goals in line with the "help insulate humanity from risk" charter Tesla has.
So yes, we need to transition from fossil fuels to renewables. But the reality is that it will take some investment (in both money and energy usage) to eventually get there. And the rest of the world isn't going to just pause until it happens.
