A conceptual model illustrates avian electrocution risk as the product of pole hazard and avian exposure (Fig. 12.4, Dwyer et al. 2016a), with each factor being independent of the other.Pole hazard is an index of the

Photovoltaic solar energy provides benefits in that no emissions are produced; however, there are potential impacts from photovoltaic solar development on birds that include habitat loss and potential for collision mortality.
The recognition of a potential conflict between solar electricity generation and birds is historical, Maag Jr. (1977) makes reference to “unwelcome migratory birds” as an environmental variable that may affect PV performance- perhaps reflecting a shift in attitude towards the conservation of biodiversity too.
First, our analysis demonstrates that a vast majority (97.4%) of areas with significant solar-energy potential intersect with the ranges of multiple threatened bird species. Additionally, over 17.0% of these areas support at least 10 threatened bird species.
Fatalities of birds predominantly are thought to be caused by collisions with turbine blades, PV panels and heliostat solar reflectors, but birds also are killed by concentrated beams of sunlight at CSP power towers, unintentional grounding at solar facilities and drowning in wastewater evaporation ponds at CSP facilities [ 12 – 15 ].
The average annual fatality estimate we calculated for photovoltaic solar (high-end estimate of 2.49 birds per megawatt per year) is lower than that reported by another study (9.9 birds per megawatt per year) that included one photovoltaic facility.
Natural England has identified birds and bats as the taxa most urgently requiring an evidence base for potential impacts relating to solar PV developments. The focus of this review will be on these taxa, however general ecological impacts will also be v. vi. vii. viii. ix. x. considered.
