Wales has set a target to generate 70% of its electricity from renewable sources by 2030.
Welsh Cabinet Secretary for Environment Lesley Griffiths announced the goal, which includes plans for 1GW of renewable power capacity to be locally owned during the same period.
She adds new green projects should also have “at least an element of local ownership” by 2020.
Ms Griffiths said: “Wales must be able to compete in global low carbon markets, particularly now we face a future outside the EU. The ability to meet our needs from clean energy is the foundation for a prosperous low carbon economy.
“I believe these are stretching but realistic targets which will help us to decarbonise our energy system, reduce long term costs and deliver greater benefit to Wales.”
