Most analyses and reviews of utility-scale, highly intermittent new renewables, especially wind power which will be the focus here, are lacking in perspective. This makes marginal aspects appear to have significance out of proportion to the very little value they represent.
A few examples are:
…· A focus on the energy contribution (MWh) from wind power leads to error in assessing the contribution to electricity costs, reliability, impact on fossil fuel consumption and CO2 emissions, transmission needs and the operation of an electricity system.
· The possibility of some improvements in wind forecasting. Given the current state of weather forecasting in general, it seems difficult to believe that wind can be forecast for short time intervals, say 24 hours in advance. In any event, even if such forecasting was possible, it does not change the need for balancing generation plants to be ramped frequently to mirror wind conditions.

WIND FARMS, RESIDENTIAL PROPERTY VALUES, AND RUBBER RULERS©
by Albert R. Wilson
I recently examined a document published by the Department of Energy’s Lawrence Berkeley National Laboratory titled “The Impact of Wind Power Projects on Residential Property Values in the United States: A Multi- Site Hedonic Analysis” (hereafter “Report”).…
Press reports in the Financial Times and other news outlets describe a wind project in Oregon with 338 machines of 2.5 MW each, giving a total capacity of 845 MW. The project sponsors claim that they will provide enough energy to serve 235,000 households and reduce CO2 output by 1.5 million tonnes annually.
Part I demonstrated that the served-household claims is fanciful. In reality, no more than 49,000 households could be “supplied”, and these with only a minimal degree of assurance. Indeed, the wind project is more costly than a diesel backup scheme that would actually be capable of supplying reliable power to several hundred thousand households. The wind project is also three times more costly than a replacement of just 211 MW of older coal capacity with new technology that would provide a similar reduction in emissions, while supplying firm power to the NW Power Pool’s customers.…
