A new report suggests that the Welsh Assembly Government should divert more attention to sustainable cheap energy.
According to a paper by the Centre for Alternative Technology (CAT), which is based in Machynlleth, Powys, there should be greater use of Wales' coastal energy as part of a UK-wide strategy to reduce greenhouse gases.
The Zerocarbonbritain2030 report also calls for all wall cavities and lofts in the UK to be insulated in order to improve efficiency and help people reduce bills from their energy suppliers.
Paul Allen, external relations director at CAT, told the BBC: "Wales enjoys abundant renewable resources.
"By moving towards a zero carbon Wales we can create thousands of new jobs, enjoy greater energy security and a more sustainable, dynamic and resilient Welsh economy."
He added that importing energy will be too costly for the coalition government given its Budget and Britain's oil and gas reserves are rapidly dwindling, so an alternative energy source has to be found.
