TY - JOUR TI - Megawatts are not megawatt-hours and other responses to Willis et al. AU - Sovacool, B T2 - Energy Policy AB - Voltaire once wrote "the perfect is the enemy of the good." My study on avian mortality (Sovacool, 2009) is not perfect, but it is still a good preliminary assessment. Willis et al. (2009) do not reveal "serious errors" in analysis so much as misunderstandings regarding some key concepts in energy policy as well as simple differences of opinion. Their critique presents adjusted fatality estimates for wind energy but not for nuclear power and fossil fuels, confuses installed capacity with actual electricity generation, and attacks me for using "gray" literature and making comparisons over large areas and time periods when many of their sources do the same.  DA - 2010/04// PY - 2010 VL - 38 IS - 4 SP - 2070 EP - 2073 UR - https://www.sciencedirect.com/science/article/pii/S030142150900648X DO - 10.1016/j.enpol.2009.08.052 LA - English KW - Wind Energy KW - Land-Based Wind KW - Birds KW - Bats ER -
