Beyond Single Marine Renewable Energy Devices: A System-wide Effects Approach

Summary

The OES-Environmental 2024 State of the Science Report addresses the critical challenge of understanding the system-wide and cumulative environmental effects of marine renewable energy (MRE) development as projects scale up to large arrays. Historically, research focused on small numbers of devices (1-6), but new frameworks are proposed to scale this understanding. A 2023 study categorized four types of scaling effects and identified seven key stressor-receptor interactions. The report details the need for integrated ecosystem approaches and cumulative effects assessments (CEAs), which gained prominence in the 2000s, and provides five key points and six recommendations for future progress in MRE impact assessment.
