Bitcoin's value is not driven by mining, mining is driven by Bitcoin value. If electricity prices rise, if there are anti-mining regulations, it would just result in migration of mining and maybe lower network hashrate. But unless this drop is very dramatic, it's not going to affect security, and if security is unaffected, the price is unaffected.
My take on this is that yes, while there will be less capital going forward, fiat is still created at the whim of commercials banks, therefore the idea of a digital cash that cant be debased is a powerful one.
Bitcoin still fails to exhibit anti-inflation or anti-crisis properties. It seems to be just as affected as the stock market and other mainstream investments. But on the other hand, the fact that Bitcoin is still alive and well means that the market indeed believes that Bitcoin has some pretty solid fundamentals.
