Effective policy and regulatory frameworks are paramount to incentivising the deployment of renewable energy to achieve long term reductions in carbon emissions. Australia's renewable energy policy has taken significant steps towards encouraging the deployment of lower-emission energy generation. Significant policy barriers still exist at the federal and state levels, however, which have reduced the effectiveness of a concerted national effort to deploy renewables. The current policy landscape has favoured mature technologies which present the lowest investment risk at the expense of emerging options which may present greater efficiency and emissions reduction gains. The lack of support for emerging technologies delays their effective deployment and the accumulation of highly skilled human capital, until the medium to long term. This paper outlines the key policy frameworks, incentives and regulatory environment which encompasses the renewable energy sector, and presents a critical analysis of the barriers faced by the industry.
