A new planning framework for Wales will aim to produce more council housing and increase the use of renewable energy.
Launching a consultation on the National Development Framework, housing and local government minister Julie James said it would include proposals for new priority areas for large-scale wind and solar energy development.
It would focus on growing existing urban areas to ensure that homes, jobs and services are located in the same area.
Cardiff, Newport and the Valleys, Swansea Bay and Llanelli and Wrexham and Deeside were identified as areas where large-scale housing and employment growth will be focused.
Ms James said: 'We know that Wales needs more good quality housing, to develop renewable energy and for people to be able to access well-paid jobs close to where they live.
'I am committed to building more council housing at pace and scale in Wales, and to see far more affordable homes to rent from councils and other social landlords.
'I want a planning system that consistently meets all our needs; and for our villages, towns and cities to be organised in a way that makes it easier to live healthy and active lives, for us and for future generations.'
