Nope. A very small portion of TVA's power generation is from hydro now. Most is from high sulfur coal. You can only get so much hydropower out of the Tennessee River and that quanity was exploited years ago. Some of the TVA generation is from nuclear, but do the tree huggers consider this as green power?

Even if it is totally green, the more green energy he uses, the less there is for others to use, requiring more CO2 producing electricity to supply the rest of us folks.
As long as "green electricity" is a limited amount, then cO2 producing electricity must make up the rest. So less energy use, whether green or not, will decrease the total CO2 output.
