Ok, I see. I was only considering renewable as green. After all, natural gas is a fossil fuel, just like natural coal, but cleaner.
The contract chart will always include significant portions of gas, since to my knowledge, gas is required to back up solar and wind sources on rainy calm days.
Tenant, that chart is what I was expecting to see. Itty bitty slice of wind/solar.
All in all I see no issue with others supporting and promoting BF. it needs to be done.
