20. Political Barriers House of Commons Hansard Debate, 23 rd March 2006 Adam Price (Carmarthen, East and Dinefwr) : “The Carbon Trust has estimated that up to 20% of the UK's energy needs could come from marine energy sources. Can the Secretary of State explain why so many tidal power projects have been rejected by the Department, and in particular the Swansea bay tidal lagoon project, which the Department has condemned out of hand as prohibitively expensive?” Alan Johnson (DTI): “ I do not accept that we have not supported wind and tidal power. There has been a focus on wind…. “ [...] I do not accept the criticism that the honourable Gentleman makes, but I do accept his point that wind and tidal power is a crucial aspect of our energy future.”
