Maybe you guys wouldn't be paying through the nose for energy if you had more solar.

Not on those terms. Nobody wants to pay through the nose and see a return in a decade. We wouldn't be paying through the nose if we used our own gas instead of importing it. Crazy idea, I know...

It wouldn't be England if the sun shone.
