Environmental Impact Assessment of WES:

Wind Energy Systems (WES) are part of the Atmospheric Energy sub-group of Earth Energy Systems (EES).  Wind energy is a global phenomenon and it is the world's fastest growing energy source.  WES utilize new technologies to provide us with another piece of the pollution-free energy puzzle.  However we must realise that all energy generation/concentration irreversibly impacts our environment.

 

1)   Potential Negative Aspects of Wind Energy Systems:

1.1    First and presently most recognised potential negative aspect is the affect on birds.  Potential for birds collisions with large wind generator blades can be envisioned by all environmentalists.  Multiplying of this potential with multiple wind towers in case of wind farms is even more concerning.  Combination of migratory routs of birds and wind farms is obviously the most concerning aspect of WES impact on birds.  Only method how to forecast these impacts is to either undertake accelerated computer modeling, or undertake lengthy (3-5 years) field studies involving existing installations.

        1.2    Second potential negative impact of WES is effect of strong Electromagnetic Fields (EMF) on various natural systems.  We are fully aware that navigation systems of birds, bats, whales, seals, fish, can be disturbed by EMF.  At present time there is insufficient information on EMF emissions of WES equipment in the air (rotor head), in the water (immediate cable area).  Land effects of EMF of power distribution grids were studied for long periods of time without conclusive evidence, however we did not see the fossil fuels burning negative signs for many years as well.  We believe that
