Abstract

Although onshore wind energy is a key pillar of renewable energy systems, installation targets in Europe have not been met. One contentious issue is its distribution, involving trade-offs between economic costs, environmental impact, public acceptance, and equity considerations. In this study, we evaluate different distribution strategies that meet Germany's national onshore wind power target of utilizing 2 % land area, breaking it down to subordinate levels such as federal states. Therefore, we define key indicators for energy policy objectives to comprehensively analyze these strategies. We employ an energy system optimization model to address the system integration of spatial onshore wind power distribution, an aspect often overlooked in previous studies. Our results indicate that the impact of different distribution strategies on the overall energy system design is moderate, with the highest sensitivity observed in the allocation of electrolyzers, which closely align with renewable energy surpluses. However, our analysis shows that concentrating onshore wind power in areas with high energy yield can lead to an increase in electricity transport by up to 38 %, whereas more evenly distributed scenarios are preferred for environmental sustainability and distributive justice. In conclusion, we argue that energy system analysis can enhance the accuracy of assessment of onshore wind power distribution, but it must consider non-techno-economic criteria within spatially-distributed energy systems itself to address policymakers.
