Tree Shaped Wind Turbines to be Installed in Paris

If you are talking about Capacity Factor (CF) as the measure of efficiency, which in Germany averaged a little over 17%, includes older turbines. In contrast, modern turbines, especially offshore turbines where winds blow more constantly, have been known to exceed 50% CF and are expected to breach 60% in the near future. As far as bird fatalities go, I agree that safety of birds, bats, etc.. is very important. The Human Race’s dominance has many times in the past led to extinction of species at detriment to our ecosystem and must be handled wisely with great innovative passion. My perspective on this design here shows no indication of risk to birds any worse than wind blowing tree branches. At low wind speeds, the spinning turbines are light in weight and slow enough to recover from an impact. At high speeds, the danger of being smacked by a branch can prove equally fatal....
