Are there any statistics of how much of the total CO2 that's produced by year is caused by computer equipment? Are there any estimates, what percentage of that is caused by mining bitcoins or other cryptocurrencies? What about things like machine learning or rendering video footage? I'm afraid that i couldn't find anything comprehensive, but something like that would be very interesting to explore!
