Smaller wind turbines & more compact wind turbines are safer, when they do have a vertical spindle and blades directly connected to it.
The big wind-turbines of course produce much Megawatt, especially for industry. But the power has to be brought by power lines to the other counties.
New developments concentrate (backstage-information) on small wind turbines based on other technical approach. The latter planned to be built at the place were the energy is used. In the future decentralised energy systems will increase, as widely achieved already in solar systems on the roofs or close and make power lines superfluous. Some wind power generation technologies could be suitable for decentralisation – such as Slavonius Rotors, which do not kill birds or bats. However much research is a needed, to develop wind energy systems, which do not harm to our biodiversity (birds and bats).
