The Paris Agreement determined to limit global warming to below two degrees. National governments are now confronted with the challenge of taking action for climate protection. For Germany, this poses a major challenge, as the imminent phaseout of low-emission nuclear energy additionally increases the pressure to quickly advance the deployment of renewable energies. At the same time, their low energy density and the resulting high land requirements lead to severe conflicts in land use. The situation is aggravated by the fact that the diversity of societal actors leads to a diversity of energy strategies, which differ in terms of impacts on land use. We therefore want to analyse the impending restructuration of energy supply and the associated land use conflicts. We model potential scenarios of energy landscapes that can be derived from the two-degree target on the basis of Geographic Information Systems, by modifying the political guidelines and planning laws for the deployment of renewable energies. The analyses show that carbon-neutrality is attainable in principle. However, the spatial patterns of renewable energies differ considerably depending on the given legal framework. It also comes to show that land use policy must take greater account of the perspectives of those social groups that are confronted with the installation of renewable energies in the immediate vicinity of their own living environment.

发展碳中和能源供应的土地利用情景——德国南部的案例研究

《巴黎协定》决定将全球变暖限制在两度以下。各国政府现在面临着采取行动保护气候的挑战。对于德国来说，这是一个重大挑战，因为即将淘汰的低排放核能进一步增加了快速推进可再生能源部署的压力。同时，其低能量密度和由此产生的高土地需求导致严重的土地利用冲突。社会行为者的多样性导致能源战略的多样性，而这些战略对土地利用的影响各不相同，这一事实使情况更加恶化。因此，我们想要分析即将到来的能源供应重组和相关的土地使用冲突。我们通过修改可再生能源部署的政治指导方针和规划法律，对能源景观的潜在情景进行建模，这些情景可以根据地理信息系统的两度目标得出。分析表明碳中和原则上是可以实现的。然而，根据给定的法律框架，可再生能源的空间格局存在很大差异。它还表明，土地使用政策必须更多地考虑那些面临在其居住环境附近安装可再生能源问题的社会群体的观点。
