Opinions and facts

Every technology has its downsides, and wind energy is no exception. In most parts of the world where wind energy is being proposed or developed, there is some sort of ‘anti-wind’ lobby. Some of the opposition to wind energy is simply a question of aesthetics, with a number of people not liking the appearance of wind turbines. This is a matter of taste, and can only lead to a difference of opinion with those who do find them attractive. 

However, to strengthen their anti-wind arguments, many opponents of wind turbines then start to try and marshal a range of facts in the case against and new development. It is here that myths and inaccuracies abound, with plenty of misinformation being put around to try and enhance the strength of any anti-wind case. Some examples are quoted on the British Wind Energy Association web site 

So, what are the facts? As well as counteracting myths, there is a very positive story to tell about the development of wind power. For this reason, the European Wind Energy Association (EWEA) have recently put together a new book – Wind Energy: the Facts – which we are publishing to coincide with this years EWEA conference. It is an amazingly comprehensive overview of the global situation with wind energy, with over 550 pages covering technology, grid integration, economics, industry and markets, environmental impacts and scenarios and targets. 

Next time anybody wants to start propagating one of those anti-wind farm myths, it should be very easy to check the facts!

To windfarm aficionados:

Many countries or areas in large countries do not have zones that are windy enough to permit an economic harvesting of wind energy.  Even in areas with moderate wind, there are groups opposed to this form of "development". In any case it should be an issue determined by a majority of those whose lives will be impacted.

I would like to take this opportunity to point out that there exists (has been patented) a "sister" technology that can harvest energy from otherwise "still" air.  It consumes the Convective Available Potential Energy (CAPE) in the troposphere,, abundant during periods of high insolation, but also extends into the evening hours.  This is actually the same source of energy that powers thunderstorms AND conventional windmills.  After all, if there were no "updrafts", creating a low pressure area, there would be no flow of wind from one region to another which could be harvested.

The technology is called the Atmospheric Vortex Engine (AVE) and is described at: http://vortexengine.ca  These would likely produce electricity far more economically in regions where electricity from other renewable sources would have to brought in using long distance transmission lines, which have their own impact.

In effect the AVE technology eliminates the somewhat capricious "middle man" which sometimes powers windfarms and sometimes doesn't.  CAPE is much more dependable and predictable (learn about it at http://www.tornadochaser.net/capeclass/
