But environmentalists insisted a "shocking lack of research" had been carried out as to their actual effectiveness in built up urban areas. It prompted Leamington-based company Encraft to launch the Warwick Wind Trials in 2006, in which a total of 23 home owners who had paid for a turbine had their energy producing levels monitored.
Iowa Stored Energy Park Agency director Bob Schulte said that geology tests found the storage reservoir wasn't suitable for the scale of project officials envisioned. Essentially, the quality of the storage rock, which would have been sandstone, wasn't as good as officials were looking for.
Indeed, the expense involved in developing renewable energy continues to be a concern ...Wind, solar and other alternative forms of energy just aren't yet competitive with traditional power sources and don't generate enough energy compared to the investment involved.
Around 20GW of planned wind farms globally face objections from air traffic controllers because turbines interfere with radars near military bases or airports. Turbines can reflect radar waves, appearing on radar screens as 'clutter' in an unpredictable and confusing way.
Others may be concerned about health issues but he said his major concern deals with the financial impact of these energy producers, especially considering taxpayers will have to pay back the funds borrowed from China for Obama’s stimulus plan.
Plugged into a socket, an electric car can draw as much power as a small house. The surge in demand could knock out power to a home, or even a neighborhood. That has utilities in parts of California, Texas and North Carolina scrambling to upgrade transformers and other equipment in neighborhoods where the Nissan Leaf and Chevrolet Volt are expected to be in high demand.
Gov. Deval Patrick's challengers yesterday demanded he come clean on a now-scrapped state plan to spend $91 million on a ship for transporting wind turbines.
Calculations by LaBrecque and his team of students found a typical $16,500 windmill only produces between 200 and 500 kilowatt hours of electricity per year - not enough to keep a 100-watt light bulb running for a year. This amounts to a $30 to $80 cost savings per year - meaning the windmill, if saving $80 a year, would pay for itself only after 206 years.
LaBrecque said energy efficiency and conservation are complex engineering issues. We can no longer depend on lawyers, lobbyist, legislators and special interest groups in Augusta who lead us down this windmill path.
The 3-1 vote reversed last month's decision by a Dennis committee of the historic district to allow the 164-foot-tall wind turbine at a shellfish hatchery operated by the Aquaculture Research Corp. in Dennis. ..."It's in a sensitive wetland area."
"Well-meaning voters and legislators come up with things like 33 percent renewables in California by 2020," said Maurice Gunderson, senior partner at the venture capital firm CMEA Capital in San Francisco. "Well, it sounds like a good idea, but you really have to be a utility geek to get into the details and realize that it simply cannot be done without storage." Mike Gravely, an energy research manager at the California Energy Commission, agreed.
The proceeds from the authority sale will be used to prepay for power from the Windy Point/Windy Flats Project, a 114- turbine wind-energy farm in Washington state. The Pasadena-based authority is purchasing the electricity on behalf of the Los Angeles Department of Water and Power and the city of Glendale.
President Obama kicked off a five-state campaign swing yesterday with a stop at a "clean energy" plant in Menomonee Falls, Wisconsin. As it happens, Mr. Obama couldn't have chosen a better company to demonstrate the risks that taxpayers are taking with their billions in green stimulus investment.
The meeting was called by Cape Vincent Supervisor Urban C. Hirschey to discuss, among other things, the "suspension of all actions pertaining to wind development" and a probe by the state attorney general's office into the actions of certain town officials in connection with wind farm development.
A proposed offshore wind farm took a major step forward Wednesday with the approval of a key contract between National Grid and developer Deepwater Wind. But R.I. Attorney General Patrick C. Lynch vowed to appeal the decision, calling it a "sweetheart deal."
Mitsubishi lawyer Filibero Agusti said other companies own similar technology that that Mitsubishi would show that at least one of GE's patents is invalid. He contended that a patent GE acquired from now-defunct Enron Corp. was purchased to pursue "sham litigation" intended to maintain its monopoly of the wind turbine market.
As the wind installations multiply, companies have found themselves dumping energy late at night, adjusting the blades so they do not catch the wind, because there is no demand for the power. And grid operators, accustomed to meeting demand by adjusting supplies, are now struggling to maintain stability as supplies fluctuate.
Little noticed recently was a joint venture announcement by two U.S. industry giants: Babcock and Wilcox (B&W), which produces technology for nuclear-powered naval vessels, and Bechtel, one of the world's largest engineering firms. They intend to complete development of a small modular 125 MW nuclear reactor that could run for four to five years without refueling, like naval power plants.
Fallago Rig wind farm developers, North British Windpower, have hit back at what they call "emotional media posturing" by those opposed to the development.
This in particular lay in the requirement that the developer, Epuron, either buy 14 affected properties or remove 19 turbines from the project. However, Mr. Price-Jones told Council that if the landholder refused to sell, the developer could just "rub his hands and say goodie, goodie," and go ahead with the turbines involved.
