I am all for witty sarcasm, but this one doesn't add much value to the discussion given weak correlation between mass surveillance and renewable energy.
You are making assumptions. How do you know what powers or will power the surveillance system in China? Also, mass surveillance will always be there regardless of forms of energy it is on, hence the weak correlation.
Not to mention running these video cameras and computer systems is fairly minor in terms of how much energy they consume compared to other activities in the country.
