And More Details...

A follow-up to Marc’s post concerning the feasibility of wind power: The power company here recently conducted an 18-month study on the potential of residential-based wind and solar power under local conditions. Their finding was that the wind turbine failed to meet expectations, the solar panels performed as expected, but neither provided a cost-benefit ration that makes it a compelling alternative for most energy consumers. Personally I think there is promise in renewable energy, residentially produced or otherwise, but studies such as this demonstrate that the technology isn’t adequate (or the price levels of conventional energy sources adequately high) to justify widespread migration to renewable energy. Yet.

Wind Power: Not So Novel After All

Friday, August 18, 2006
How different is this...
In a recent WSJ story, “A Novel Way to Reduce Home Energy Bills,” Sara Schaefer Muñoz writes about the possibility of adding windmills to homes in order to cut down on the cost of utilities.

“While wind energy is commonly associated with massive turbines churning in desolate, windy areas, a new generation of smaller systems made for areas with moderate wind is hitting the market. The latest small turbines, which resemble a ship propeller on a pole, have three blades, are up to 24 feet in diameter and are usually perched on stand-alone towers between 35 and 140 feet high. The systems have the potential to save consumers between 30% and 90% on their electric bills, manufacturers say, and promise to make no more noise than an air conditioner,” says Muñoz. “But tapping so-called small wind using a high-tech windmill can be costly, and homeowners may find themselves battling zoning officials and annoyed neighbors who find the towering devices unsightly.”

Is this just a case of NIMBY? After all, we’re not likely to see these things in urban areas: “The systems aren’t for city dwellers or residents of tightly packed suburbs. Those interested in small systems should have at least a half-acre of property, wind speeds of at least 10 mph and electric bills of $60 a month or more to make installing the system worthwhile, manufacturers say.” One of the companies profiled is the Bergey Windpower Company, who makes the BWC Excel, “America’s most popular residential & small business wind turbine.”

...from this?
Zoning officials will no doubt use the “novelty” of the idea as a way to impede the use of these windmills, but in a real way there’s not much that’s novel about these systems at all. Sure, they convert wind power into electrical power instead of kinetic energy, but other than that, they function a lot like windmills have for hundreds of years.

As Rodney Stark writes in his book, The Victory of Reason (for which I’m in the process of writing an overdue review right now), in the Middle Ages, “Windmills proliferated even more rapidly than waterwheels because there was wind everywhere. In order to take full advantage of the wind even when it shifted direction, medieval engineers invented the post mill, which mounted the sails on a massive post, leaving them free to turn with the wind. By late in the twelfth century, Europe was becoming so crowded with windmills that owners began to file lawsuits against one another for blocking their wind.”

Environmental News Roundup

Monday, July 24, 2006
Juliet Eilperin, “Bush Pollution Curbs Are Rated Equal to Clinton’s: Science Panel Says Proposed Cap-and-Trade System Will Help Clean Air,” Washington Post, July 24, 2006:
The report from the National Academy of Sciences, released yesterday, represents the latest effort to assess how best to reduce air pollution estimated to cause as many as 24,000 premature deaths each year. The panel concluded that an earlier Bush plan would have allowed pollution to increase over a dozen years, but it found that the administration’s more recent Clean Air Interstate Rule (CAIR) -- which targets emissions from power plants in 22 states and the District of Columbia -- would help clean the air over the next two decades.

The CAIR approach aims to reduce nitrogen oxide and sulfur dioxide emissions by 70 percent by 2025 at the latest, according to the Environmental Protection Agency, through a system that would allow utilities to sell and buy pollution credits as long as industry emissions as a whole stayed below a pre-set cap.

Cap-and-trade schemes may be better than command-and-control techniques, but maybe they’re not all they’re cracked up to be.

Hugh Ross, “The Faint Sun,” Facts for Faith, Reasons to Believe, 2002:
The timing of humanity’s arrival—near the end of life’s long tenure on Earth—may appear tragic at first glance. But a longer look suggests it may be viewed as a gift. Scanning the horizon of civilization—farms, ranches, towns, cities, and all the transportation and communication arteries linking them—one sees a plethora of building materials derived from nearly 4 billion years of life and death: gems, sand, steel, asphalt, concrete, copper, limestone, marble, plastics, etc. Most of the energy that drives civilization comes from biodeposits—oil, coal, wood, kerogen, natural gas, and so forth. Many of the fertilizers that support agricultural production also come from biodeposits—phosphates, nitrates, and such.

Such bountiful provisions powerfully indicate a Provider who carefully planned and prepared the planet through the ages for human life. They speak of a purpose for the human race. The Bible reveals a purpose that involves, yet goes beyond, the current “heavens and Earth.”

More here on the providential purpose for petroleum. (HT: John Linsley of RTB)

Associated Press, “Christian Ministry Wants to Build Turbines to Spread the Gospel,” The Church Report, July 23, 2006:

A Christian ministry group wants to build 36 wind turbines on the roof of a former steel company to generate money to help spread its message....

Energy produced by the turbines will be sold back to Wisconsin Energy Corp. through a buyback program.

More here on these so-called “Cuisinarts of the air.”

Great Lakes Wind Power

Monday, June 26, 2006
A three-day meeting is scheduled to begin tomorrow in Toledo, Ohio, and is set to discuss the possibility of putting wind farms on the Great Lakes. The session is sponsored by the U.S. Fish and Wildlife Service and the Environmental Protection Agency among other groups, and will include conversations about “how to protect birds, bats and fish from the windmills.”

According to the AP, wind farms on the Great Lakes would include “rows of windmills” that “would tower as high as 400 feet and float or stand in relatively shallow water.” Some opponents of wind farms point out the danger that the turbines can represent to migratory bird populations. Acton’s Anthony Bradley has noted that the Sierra Club calls wind towers “Cuisinarts of the air” (listen to related interview here).

The attractiveness of wind farms based on water rather than land has to do with the relatively greater strength of wind which sweeps over bodies of water. Walt Musial, a senior engineer and offshore programs leader for the National Renewable Energy Laboratory, a U.S. Department of Energy contractor, said, “Offshore machines can make about twice as much as onshore.”

Other concerns relate to the high startup and capital costs involved in the construction of these projects, perceptions about the unpredictability and unreliability of wind power, and issues of visual pollution.
