Less For More: The Rube Goldberg Nature of Industrial Wind Development

Rube Goldberg would admire the utter purity of the pretensions of wind technology in pursuit of a safer modern world, claiming to be saving the environment while wreaking havoc upon it. But even he might be astonished by the spin of wind industry spokesmen. Consider the comments made by the American Wind Industry Association.s Christina Real de Azua in the wake of the virtual nonperformance of California.s more than 13,000 wind turbines in mitigating the electricity crisis precipitated by last July.s .heat storm.. .You really don.t count on wind energy as capacity,. she said. .It is different from other technologies because it can.t be dispatched.. (84) The press reported her comments solemnly without question, without even a risible chortle. Because they perceive time to be running out on fossil fuels, and the lure of non-polluting wind power is so seductive, otherwise sensible people are promoting it at any cost, without investigating potential negative consequences-- and with no apparent knowledge of even recent environmental history or grid operations.

Eventually, the pedal of wishful thinking and political demagoguery will meet the renitent metal of reality in the form of the Second Law of Thermodynamics (85) and public resistance, as it has in Denmark and Germany. Ironically, support for industrial wind energy because of a desire for reductions in fossil-fueled power and their polluting emissions leads ineluctably to nuclear power, particularly under pressure of relentlessly increasing demand for reliable electricity. Environmentalists who demand dependable power generation at minimum environmental risk should take care about what they wish for, more aware that, with Rube Goldberg machines, the desired outcome is unlikely to be achieved. Subsidies given to industrial wind technology divert resources that could otherwise support effective measures, while uninformed rhetoric on its behalf distracts from the discourse.and political action-- necessary for achieving more enlightened policy.

Editor's Note: The following are selected excerpts from the Renewable Energy Foundation press release describing this research. The full press release is available via the link below.

Using the new research it is now possible to assess how renewable generators up and down the country are performing. This data, published in five online files; Biomass, Hydro, Landfill Gas, Sewage Gas and Windpower, shows that firm generators are producing high load factors with carefully designed resource use and load following.

However in the wind sector, far and away the most active of all the technologies at present, results vary enormously due to location. The capacities offshore are encouraging, whilst those onshore are generally only superior in locations very distant from the populations requiring the electrical energy.

Although most sites were built on expected capacity factors of around 30%, results include;
19% (approx) capacity factor for the wind turbines at Dagenham, Essex.
9% (approx) capacity factor at the Barnard Castle plant, County Durham.

The best performing wind sites are in the north of Scotland, and on Shetland the wind turbines are producing capacity factors of over 50%.

Using this analysis of the Ofgem data, researchers have also calibrated a model predicting how a large installed capacity of wind power built across the UK would actually perform. The project used Meteorological Office data to model output for every hour of every January from 1994-2006.

The startling results show that, even when distributed UK wide, the output is still highly volatile.

The average January power variation over the last 12 years is 94% of installed capacity. It is an uncontrolled variation decided by the weather.

The average minimum output is only 3.7% or 0.9GW in a 25GW system.

Power swings of 70% in 30 hours are the norm in January.

The governments’ expectation is that three quarters of the 2010 renewables target, and the lion’s share of the ‘20% by 2020’ target will be made up of windpower.[2] However, the new research offers predictions which are in keeping with Danish and German empirical experience and demonstrate the need for a broader spread of investment in the renewable sector. <br.
The report was commissioned from Oswald Consultancy Limited and funded by donation from the green entrepreneur Vincent Tchenguiz.

Campbell Dunford, CEO of REF, said: “This important modelling exercise shows that even with best efforts a large wind carpet in the UK would have a low capacity credit, and be a real handful to manage. This isn’t the best way to encourage China and India to move towards the low-carbon economy. As a matter of urgency, for the planet’s sake, we need to bring forward a much broader range of low carbon generating technologies, including the full sweep of renewables. Wind has a place, but it must not be allowed to squeeze out other technologies that have more to offer.”

Q. Please state your name and position.

A. My name is Charles Simmons and I have been retained to provide assistance to Highland Citizens in regard to the application of Highland New Wind Development, LLC to construct a wind generation facility in Highland County.

Editor's Note:This testimony provides an excellent description of how a grid works- particularly the role of 'economic dispatch' and 'spinning reserves'. It also addresses the methodology for estimating emissions savings and numerous other topics of interest.
