The previous Government looked at the Swansea tidal lagoon in great detail and depth, but the decision was taken before my time in the Department for Energy Security and Net Zero not to proceed with it. I am informed that it was due to a combination of the cost and the reluctance of those involved to make the case that the technology would be successful. However, if it can be presented as a viable project—if the costs can be brought down and the technology can be proved to work—of course the current Government could look at it again. We should be investing in things that work and that return a benefit to the taxpayer. Last week, the UK learned the word “Dunkelflaute”—I have probably pronounced it terribly—which expresses what happens when the wind does not blow and the sun does not shine. The recent cold snap illustrated just how insecure a system reliant on intermittent renewables such as solar and wind will be, so we need to invest in new baseload generation, including gas, nuclear and tidal. Those technologies sadly got little mention in the Secretary of State’s “Clean Power 2030” action plan. There were few words about nuclear and nothing about tidal—seemingly, no plan for future generation. It is clear that a wide mix of energies will be required to ensure our energy independence and security. Offshore wind and solar are obviously essential parts of the mix, but so too will be—or at least should be—oil and gas; nuclear, large and small, with microreactors; and new and emerging technologies such as wave and tidal. The developments happening across all those technologies in this country are great. We should support Great British and Northern Irish scientists, innovators, engineers and technicians who have the opportunity to build on the successes of the past decade, which saw Great Britain and Northern Ireland lead the world in investing in new energy generation. To echo the sentiment of other right hon. and hon. Members, we need more direction and clarity from the Government about where we are heading on this journey to more tidal and wave investment. We fully support the calls for a road map and a taskforce to drive that forward and support the industry. I say to the Government: please do not just put all our eggs in two baskets, but invest in and support other technologies. We need all those energy sources in future. Many of the technologies will be developed and deployed around the coast, in some of the more deprived communities in this country, so the jobs and investment that they will contribute will be massively beneficial not just for our energy security but for the wider economy. If we invest now—if we spend the time and money and expend the energy—Great Britain and Northern Ireland can yet again be the beating heart of this new global industrial revolution.
