THE PLACES PAVING THE WAY TO 100 PERCENT RENEWABLE ENERGY

I bet those communities are still all served by the legacy grid that has plenty of reliable (aka fossil) energy in it to prevent it from going down. Or am I wrong? Does anyone actually know. I have seen companies that claimed they are 100% renewable. In reality, all of them are connected to the same grid as we are and they pay some money for bragging rights. In my book, all those companies and cities would be taken off the grid at once. Let them have only what they claim they like so much.
