Householders in Gwent could soon find it easier to install small-scale energy generating equipment such as solar panels or wind turbines.
National Assembly leaders want less restrictive planning rules so individuals and communities can do more to combat climate change.
As the idea goes out to consultation, it was welcomed by Newport West AM Rosemary Butler.
Mrs Butler said: "There have been examples all over Wales of people trying to tackle climate change, but who have been refused permission to install solar panels or other micro-generation equipment on planning grounds.
"It's not the fault of local authorities. It's just that the regulations are too inhibiting."
She added a more flexible approach would undoubtedly encourage householders and communities to set up their own renewable energy schemes to a much greater extent that had been seen so far.
Ian Irving is one of her constituents who fell foul of the planning regulations when he wanted to install solar panels at his home in Isca Road, Caerleon, about two years ago.
His proposal was turned down by the city council because he lives in a conservation area.
"The problem was I couldn't put them on the back of the house because there was not sufficient sunlight so they had to go in the front.
Even so they would hardly have been visible to anyone walking down the road because of the angle on the roof."
He thought it was a good idea to review the present rules. "After all it is a help for the environment and makes use of a resource that is there and is free."
Mr Irving emphasised that he was not against conservation areas and the need to protect their appearance. "But in this case I did not think it would be noticeable."
