Challenges of dismantling abandoned wind and solar farms

Researchers studying decommissioned wind and solar farms in Italy, Spain, Venezuela, and Argentina have found that weak regulations risk leaving more abandoned assets in their wake. When renewable assets near the end of their operational life, project owners can decommission, repower, renew, operate to failure, or abandon on-site equipment. In a largely decarbonized future, large-scale solar could occupy 0. 5% to 2. 8% of land in the European Union, but multipurpose land use could potentially ease its footprint. Despite this flexibility, University of Granada researchers analyzed the landscape ...
