$12 million worth of electricity every 10 minutes is indeed mind boggling. I don't expect that BTC will be valued at $1 million anytime soon, but if that would happen, and a large percentage of the world population would use Bitcoin, it would have captured a large percentage of global capital and market activity. So for this scenario, judging the future price of electricity in USD doesn't tell you much about the actual value of that electricity. But there are many other uses of energy that various subsets of people don't agree with, yet, as long as that electricity is paid for, the system keeps chugging along. What we have to fix is that tragedy of the commons, where we dump carbon dioxide in the atmosphere at no cost.
