Energy Bill

My right hon. Friend has given me a reason to be cheerful, as progress will be made on appraising the possibilities of Severn tidal power. Many local Members of Parliament—including me—Greenpeace, the Severn tidal power group and others will welcome the announcement. On two occasions, my right hon. Friend has referred to a Severn barrage. Will he reassure the House that all feasible technologies for using tidal power will be appraised? I suggest that there is no disagreement among sensible people that tidal power is critical, but the technologies need to be appraised.
