Bridging the "Perception Gap"
The Clean Energy Solutions Index (CESI) is Australia’s annual research programme measuring deep public support for 11 clean energy technologies - tracking how sentiment shifts as the energy transition accelerates.
Explore the Clean Energy Solutions Index data for yourself through the interactive dashboard.

About the index
89 Degrees East and Boundless Earth created the Clean Energy Solutions Index, now in its second annual wave of research.
Moving Australia beyond the climate wars, the Clean Energy Solutions Index provides the evidence leaders need to accelerate Australia’s clean energy transformation.
The Index measures deep support for the specific solutions driving our energy transition.
Key insights
The Index demonstrates that deep support for clean energy solutions is growing in Australia.
Deep support continues to remain highest for clean energy solutions Australians know and understand – particularly solar, which is seen as proven, accessible and beneficial.
In 2026, the economic case is increasingly central to that support: Australians show the deepest support for solutions that lower energy costs and strengthen Australia’s energy independence.
National support score
Australia's national clean energy support score: 61 out of 100 in the 2026 Clean Energy Solutions Index, up 1 point on 2025. The Index score is the average level of deep public support across all 11 clean energy solutions measured.
Dashboard
The interactive CESI Dashboard puts two years of national data in your hands – compare 2025 and 2026 findings by solution, state and demographic to track how public support is shifting.Â
In a moment where evidence-based, community-informed leadership has never been more important, the Index empowers decision-makers to act with confidence, maintain momentum, and plan for lasting change.
Solution support scores
The Index measures deep support for 11 clean energy solutions across three categories: Home Solutions, Infrastructure Solutions and Industry Solutions.
The support score for each solution is calculated using four key metrics — personal support, belief in national benefit, perception of local support and willingness to advocate.
Further insights into barriers and opportunities to grow support are derived from non-Index data collected in the survey.
A support score of 70 or higher indicates strong social licence, and shows where mandates can be reinforced or where action is needed to grow support.

State scores
State Scores help identify regional differences in attitudes towards clean energy.
The Index allows a support score to be calculated at the state level. A State Score is the average of all clean energy solution support scores within that state.
The Index allows a support score to be calculated at the state level. A State Score is the average of all clean energy solution support scores within that state.
In 2026, the support score for each state was at least 58 or higher.
The highest state support score is recorded in Tasmania (69), while the lowest support score is seen in Queensland (58).
Year-on-year comparison is available on the CESI Dashboard.
