Author: Fahlén, Per; Henrekson, Magnus; and Nilsson, Mats
This policy brief critically evaluates the current push for extensive wind power expansion in Sweden. This Policy Brief critically examines the economic and technical assumptions behind the rapid expansion of weather-dependent energy sources such as wind and solar, identifying several systemic risks and shortcomings. Key Findings 1. System Stability Risks A high share of intermittent power (currently 25% wind and 2.5% solar) threatens grid reliability. Essential system functions (instantaneous power, frequency control, reactive power, inertia) are inadequately supported by wind . . .

Author: Bush, Amanda; Lumsden, Lindy; and Prowse, Thomas
Background: Harnessing wind energy, using wind turbines, is a prominent form of renewable energy production. There are, however, biodiversity impacts, including collisions by birds and bats with rotating blades. High levels of mortalities can cause localised and species-level population declines, which is especially significant for threatened species. The height at which species fly is a key collision risk factor. In this study we investigated the flight height patterns of a critically endangered bat to inform mitigations to reduce impacts. Methods: . . .

Author: Clerc, Jeff; et al.
Abstract. Wind energy is important for achieving net-zero greenhouse gas emissions but also contributes to global bat mortality. Current strategies to minimize bat mortality due to collision with wind-turbine blades fall broadly into two categories: curtailment (limiting turbine operation during high-risk periods) and deterrence (discouraging bat activity near turbines). Recently, there has been interest in combining these strategies to achieve greater reductions in bat fatalities than either strategy might achieve in isolation. To investigate the effectiveness of combining curtailment with . . .
