The Sustainable Energy Association of Australian (SEA) was officially incorporated in July, 2002 as the Western Australian Sustainable Energy Association Inc. The Association was established in response to an identified need for representation of the sustainable energy industry in Western Australia.

The aim of the association is to give voice to those with an interest in sustainable energy and to promote the development and adoption of sustainable energy technologies and practices.

SEA is the peak body for sustainable energy in Australia.

SEA works on behalf of all members to ensure that the State and Federal Governments adhere to sustainability principals, and are committed to mitigating greenhouse gas emissions through the deployment of sustainable energy solutions and adopting practical measures to adapt to climate change.
