Too late. Manufacturing and installing renewables or EV’s or literally anything requires diesel.

The entire industrial supply chain is still built on diesel with decades to go before the current glacial pace of electrification makes a significant dent. A massive energy crunch is just going to make renewable buildouts even more materially constrained and astronomically more expensive, there is no way out without economic collapse. The current economic system is not designed around anything other than fossil fuels and will refuse to complete a changeover until no other options exist, which will usually mean billions of homeless starving people getting fucked over.
