” Bats do not fly all the time, says Hubert Lagrange, Research Director at biotope . Most avoid winds over 6 m per second . ” A speed below which, on the contrary, wind turbines have a low yield: they run at full power at wind speeds well above, to 25 m per second, threshold beyond which they stop for safety reasons . ” Bats - mice are also active for only a few hours after sunset and for a short period before dawn, adds the researcher . Finally, outside the summer – May to October -, they hibernate . “
” Popo wala kuruka wakati wote, anasema Hubert Lagrange, mkurugenzi wa utafiti katika biotope . Zaidi juu ya kuzuia upepo 6 m kwa pili . ” kasi ya chini ambayo, kinyume chake, upepo turbines kuwa na mavuno ya chini: wao kukimbia katika mamlaka kamili kwa kasi ya upepo vizuri juu ya, kwa 25 m kwa pili, kizingiti zaidi ambayo wao kuacha kwa sababu za usalama . ” Popo - panya pia ni kazi kwa masaa machache tu baada ya jua kutua na kwa muda mfupi kabla ya alfajiri, anaongeza mtafiti . Hatimaye, nje ya majira ya joto – Mei-Oktoba -, wao hibernate . “
