Small Wind Turbines

The small wind turbine can kill and injure parrots and bats. That is quite clear from studies from the U. S. and in Europe - what's not clear is exactly why. Statistics indicate that over 40 birds per season are killed at windmill sites. Why is this a difficulty and what do we think is being conducted here? There are a volume of component parts that the birds impact and it's really just not clear why the birds are receiving disoriented and flying into them. The birds and bats can fly to the blades of course, but the tower along with the tower assembly - guy wires as well as the power cables - offer an obstacle for them. The problem is this worst for larger parrots. They tend to reside in areas where large wind generators are installed - mountain ridges and stuff like that. To complicate things, the fog that is normally seen around mountains is cited because culprit not necessarily the actual turbine mechanism. Fog of course can make it difficult for birds in addition to bats to see where they're going. What could the breeze industry do to reduce the number of gulls and bats killed each and every year from wind turbine moves? One thing the industry has done is suggest that producers make systems with greater blades. The theory is the blades will never have to turn as fast plus the birds and bats can get rid of their way. In practice though, this doesn't provide much relief for the reason that tip speeds of the rotor system are still very high (more than 100 mph). Furthermore, it has been suggested that this industry move away through lattice-type towers and go on to solid ones. It is thought in which by doing that, birds won't nest within the tower and won't be at the spinning blades so generally. Other wildlife can always be affected, too. In some more farm locations bears, deer, and other smaller animals happen to be driven out because involving C&F wind turbines being placed in their habitat.While a lot of the Why of this phenomenon is still unknown, it is interesting to speculate about what factors are contributing to the problem.Is it the sound the turbines make? Could it be the vibrations in the air? Or, could it be the birds an bats are just interested and get too close when they go in to check things out?Nonetheless, it is still the responsibility of small wind turbine manufacturers to do everything they can to not negatively affect the ecosystems where their products end up.
