To ask the Secretary of State for Energy if he has any plans to reassess the potential for wave power; and if he will make a statement.
As I announced to the House on 13 November 1989, an updating study to review cost, technical and commercial viability and prospects for wave energy in the United Kingdom is currently under way. The views of all interested parties are welcome and I will ensure that they are all taken into account. Further consultation will take place as work progresses and the final report will be published.

To ask the Secretary of State for Energy if he will make a statement on the development potential of Salter's Duck.
While my Department has no current plans for additional funding of this project, an updating study to review wave energy in the United Kingdom is currently under way. Interested parties will be consulted fully as this study progresses; indeed, only last week I met Professor Salter to ensure that I was personally aware of his views.
