Tesla's mission is to accelerate the adoption of renewable energy sources. This doesn't directly counter that. In fact you could argue that pushing the world to rely on massively energy-inefficient proof-of-work rather than a centralized authority for trust in the financial system is going to make the need for renewables even greater.
If (and it's a big if) we can get to 10% renewable energy in the next decades, Bitcoin's energy consumption will be much less of an issue.
There is no lack of demand for energy. The world is absolutely ravenous for energy. The reason we don't have more renewable energy is absolutely not, in any way, because of there not being a big enough demand for energy.
No, what Tesla has done here will instead wipe out all the gains in reducing carbon emissions it has managed so far, out of pure greed.
