Mr. Stephen Wheeler:

To be fair, I do not want to do an injustice to wave energy; it is not my brief. I believe the environment is the challenge. It is something we have seen in offshore wind but offshore wind is above the water. Once we go below the water, that environment is incredibly challenging.

Technology advances are coming but they are much slower to come than offshore wind technology. That is the reason offshore wind is the one technology that offers scale.
