Researchers: Emma Flukes (Point of contact) ,  Hemer, Mark (Author)

Brief description The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "Pressure of Offshore renewable energy generation". ***A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - Offshore Renewable Energy Generation"*** ---------------------------------------- DESCRIPTION OF PRESSURE Offshore Renewable Energy (ORE) is yet to be deployed at scale in Australia. To date, only small scale (<500 kW) experimental / prototype wave and tidal technologies have been deployed. Offshore wind is a commercial industry internationally, not yet deployed here. Several development proposals for large offshore wind farms (>100 MW) are progressing, with the most mature proposal being offshore eastern Victoria, currently undergoing environmental assessments under a Commonwealth exploration license. DATA STREAM(S) USED IN EXPERT ASSESSMENT Given the limited deployments in Australian waters, data used in the assessment is inferred from international assessments. ---------------------------------------- 2021 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details] • 2021 • Assessment grade: Very low Assessment trend: Unclear Confidence grade: Limited evidence or limited consensus Confidence trend: Evidence and consensus too low to make an assessment Comparability: Grade and trend are comparable to the 2016 assessment • 2016 • Assessment grade: Very low Assessment trend: Unclear Confidence grade: Limited evidence or limited consensus Confidence trend: Evidence and consensus too low to make an assessment Comparability: Grade and trend are comparable to the 2011 assessment • 2011 • Assessment grade: Very low Assessment trend: Unclear Confidence grade: Limited evidence or limited consensus Confidence trend: Evidence and consensus too low to make an assessment ---------------------------------------- CHANGES SINCE 2016 SOE ASSESSMENT No change

Lineage Statement: QUALITY OF DATA USED IN THE ASSESSMENT Data used in assessment is not necessarily suited to Australian conditions.
