One of the largest unions in Wales, Unite, has thrown its weight behind proposals to bring a tidal lagoon to Swansea Bay.
The £800m project could provide electricity for thousands of homes in Wales.
It's expected to be completed by 2018.
The union understands the project will create over 1900 full time jobs during the construction phase, with further jobs becoming available post construction.
“The lagoon is both superb and significant in terms of the vision, energy and employment potential it could bring to Wales. It represents the beginning of a whole new industry in South West Wales and opens the door of opportunity to sustainable skills and jobs that will not only be good for Welsh workers but for the wider Welsh economy."
