Since the 1990s, (onshore) wind power has become an important technology for electricity generation throughout the world. The economic rationale is the mitigation of negative externalities of conventional technologies, in particular emissions from fossil fuel combustion. However, wind power itself is not free of externalities. Wind turbines are alleged visual and noise impacts as well as threats to wildlife. Further indirect economic effects comprise costs for integrating variable wind electricity into the power system. Economic outcomes, such as employment and GDP, can be positively or negatively affected both locally and nationally. This Roundup summarizes evidence from multiple literatures on mitigated and imposed external costs and further indirect economic effects.
