The hon. Gentleman will know that we have spent tens of millions of pounds looking at wave energy—we have Wave Hub off the coast of Cornwall and we have invested substantially in many of the trial sites. As we debated at the time, the problem with the Swansea lagoon was not the source of power per se, but the fact that it was the most expensive power station proposal we had ever had in the UK, and it is right that we care about taxpayers’ money. That said, we are always interested in looking at tidal: several other proposals have been brought forward, and the door is always open. I, like him, know the power of the Bristol channel, having grown up on the other side; the problem is delivering it in the most cost-effective way.
