Wind power is unpredictable: iLIVE

This article as presented is highly misleading.

It fails to mention the principal drawback of wind power, which is its unpredictable and intermittent nature in most locations and certainly in Southern Africa.

Thus it has to be linked to expensive energy storage or standby power supplies which, in South Africa at least, at least double the real cost of reliable power and probably increase it far more. Further and quite obviously, the actual cost per kilowhatt hour is totally dependent on the location and its winds, so to quote single low figure is nonsense.

Of course articles like this are manna from heaven for the windmill salesmen, but if accepted by a non-technical public and the politicians they elect, can only result in much more expensive electrical power and consequent economic and social ills.

Altogether a highly regrettable one-sided article.
