Lords ChamberI understand the point the noble Lord makes. A Severn barrage scheme has been talked about since I was an electrical engineering student, way back in the 1980s; it is not a new scheme. It all comes down to the cost and the environmental damage that would result from implementing it. We continue to keep all these things under review. I assure the noble Lord that both I and the department know all about the details of the scheme.
My Lords, I add my comments to those made in relation to both tidal and wave power. We have the second-largest tidal range in the world. Some 40 years ago, I lobbied the Government on the Severn barrage, but there are many alternatives. They are not small power generators but potentially very substantial generating powers, particularly wave power.
The barrage schemes are potentially large-scale schemes. I meant that some of the bottom tidal schemes are on a relatively small scale. It all comes down to cost. The costs of these schemes fall on bill payers. The Government’s general approach is to support forms of renewable power that offer the best value for money for taxpayers—principally solar and wind, but we are starting to support some of the other tidal schemes as well. The barrage schemes are extremely expensive and very long term, and there are a lot of environmental implications.
