Issue 588 Problems with wind power May 11, 2015

Like solar, wind power has its problems as well.  So let's discuss.

Space issues:  Wind power, like solar, is free energy.  However, to get a large enough amount of electricity from wind, you need a wind farm that covers vast areas of land.  As such, it eats up large areas of land that can be protected for wildlife/forests, or used for farming, or even used for development.  As such, efforts to increase efficiency, or place them out of the way are being made.  One such solution is leasing parts of farmland so that a farm can exist underneath the turbines which makes the land usage more efficient.  Another is to integrate the turbines into the city by putting them on roofs, or have them tethered to blimp like structures.  Other ideas are being looked at, but the one I see that is best is integrating the most efficient wind turbine into someone’s house so that people can generate the electricity they need themselves without the need for some utility company.

Catching the wind:  The other issue is one that is well known.  What if the wind is not blowing?  Well, truth is it is always blowing usually, we just have to reposition the turbine into the direction and altitude of the wind.  So even if there is no wind at ground level, it may be blowing well at two stories up, and could be even stronger at six stories in the air.  So the tethered approach is one way to solve this, or to have a telescoping neck for the turbine to elevate itself as high as possible to catch the strongest winds possible.  There are also turbines being developed that will spin even with the gentlest of breezes which will mitigate the need to go a full six stories in the air just to catch wind.  Thus it is also an issue of efficiency with respect to the rotors on the turbine itself.


Conclusion:  Like solar, wind power generation is still coming along at a slow pace due to the imperfections of this technology.  But given enough time and investment, you too may be attaching a turbine to your home.
