True, they're all about 50% renewable this year, aiming to be 100% at some time. I'm a bit skeptical of this argument though. If we go down this path we have to answer what percentage of bitcoin mining is from renewable sources too. As I understood it (correct me if I'm wrong) a very large amount of Bitcoin mining is located around hydro sources to get cheap hydro electricity. That would mean the same argument that Youtube is green would apply equally to Bitcoin. But then I suspect someone would say something like "well they're using power from a hydro dam in china but look at all of China's coal plants, now other chinese people have to buy from those coal plants" to which we'd probably have to then say "yeah, kind of like when Microsoft buys Columbia river power cuz it's cheap and green or Facebook buys solar and wind power because its green that means that someone else in America can't buy that green power and is "using" power from one of our coal plants too". It's all one grid at the end of the day.
