Ishpeming, Michigan [RenewableEnergyAccess.com] Construction is currently under way this month on a rare wind energy project, a 200 kilowatt (kW) vertical-axis wind turbine outside a large residential complex in Michigan.

3M has announced the availability of their new Wind Tapes 8608 and 8609, which provide long-lasting protection from damage caused by sand, rain, moisture ingression, insects, and airborne particles. The new tapes are also formulated to resist the damage and weakening effects of ultraviolet rays.

The Obama administration wants to rebuild the national electric grid that delivers power to everyone's toasters and televisions. One reason is that the grid can't handle all the new solar and wind power the president wants to build to create a greener energy economy. Here's the problem: Solar and wind power are intermittent. Sometimes it's sunny, sometimes it's not, and it's the same for wind. But the grid needs constant and reliable sources of power.

As consumers, we pay the full market price for wind-generated electricity plus the value of renewable energy credits mandated by the Legislature. As federal taxpayers, we donate another two cents per kWh, and support the fast depreciation (tax savings) allowed wind installation entrepreneurs. Mars Hill’s units produce 1 percent of Maine’s electricity and 0.01 percent of New England’s. The Kibby Mountain proposal of 44 three-MW units is projected to produce about .37 billion kWh per year. The number of kilowatt-hours supplied by the wind is very small. The combined output from Mars Hill and Kibby Mountain would be about 5 percent of Maine’s or .5 percent of the total New England grid. The real cost of wind energy, if broken out on our electric bill, would be a shock.

Researchers seeking to make the ocean's salty brine drinkable using wind power will spend the next year using the town of Hull as a case study to help other water-needy, windswept coastal areas filter freshwater from the sea.

With one wind turbine already spinning, another to be installed in January, and a third offshore turbine being considered, Hull is an ideal laboratory for modeling a desalination plant that runs off a combination of renewable energy and the electric grid, according to James Manwell, director of the Renewable Energy Research Laboratory at the University of Massachusetts at Amherst.

April 24, 2006 issue - As projects to build "wind farms" of massive, electricity-generating wind turbines continue to multiply, so do the ranks of "not in my backyard" protesters.

The race to build new sources of alternative energy from the wind is running into a formidable obstacle: not enough windmills...Numerous wind-power projects from Virginia to California have been stalled due to the shortage. But for some renewable-energy companies in Europe, where wind power has been in vogue for almost two decades, the logjam is a lucrative opportunity. These firms anticipated a shortage of turbines and locked in orders with makers. They're now using their considerable buying power to gobble up smaller utilities in the U.S. that couldn't otherwise get their hands on turbines.

The excitement amongst Danish alternative energy producers was tangible late Wednesday night as US president uttered the words 'America is addicted to oil' and that something must be done about it.

Cheaper, user-friendly turbines could pave the way for more investment.

AWEA and Wind on the Wires (WOW) filed protests with the Federal Energy Regulatory Commission (FERC), asking it to reject out of hand the Midwest Independent System Operator's (MISO) proposed changes to the rule's pro forma low voltage ride-through (LVRT) and reactive power provisions for wind generators.

Solar is sexier. Hydrogen gets the hype, and it's not even a renewable energy. But energy experts know only wind - a power source so old and familiar the Phoenicians had it licked - can satisfy 20 percent of U.S. electricity needs in the foreseeable future. President Bush's 2006 Advanced Energy Initiative cited the 20 percent figure as a goal, saying the country should "dramatically increase the use of wind energy." Without major advances in wind and related technology to boost output, reliability and transmission while cutting costs, experts say such a leap may never happen.

Gordon expects the federal report to closely parallel the state's positive environmental impact report issued by Bowles. But even if the federal report is favorable toward Cape Wind, it does not mean an end to the fight, something Gordon readily admits. "I don't want to be naive about legal challenges," he said in a telephone interview yesterday while on a family vacation in Vermont. But with public opinion polls indicating majority support for the project statewide, he imagines a day when even his detractors will come around. "I'm hoping that even the opponents, diehard opponents, will hopefully have a shift in their attitude and hopefully stop trying to delay and obstruct a project that is needed and enjoys growing support," he said.

Capital cost of wind development has significantly increased over the past five years, said a panel of independent wind developers. The cost of transporting a large-scale turbine is about 20 percent of the cost of the equipment and land costs, and royalties to land owners are increasing as well, said Jan Paulin, president and chief executive officer of Padoma Wind Power, LLC at the 2007 Wind Power Finance and Investment Summit in San Diego. Land cost has increased about 60 to 70 percent in the last two years. The two major reasons behind the cost increase are fuel costs, especially high petroleum prices, and the perceived supply shortage of turbines also drives cost of the turbine and its transportation up. Another growing capital cost is in risk management because of the lack of strong warrantees. For a $3 million turbine, the average warrantee is for $20,000. Wind per kilowatt hours is cost competitive to fossil fuels, but the high capital cost, along with substandard warranties, make it difficult, for independent developers especially, to fund a project from start to finish. The capital cost has caused many consolidations of smaller developers into larger companies.

... a coalition of local utilities is grappling with one of the thorniest challenges in the field of renewable power: how to store the excess energy windmills create when demand is low so it can be used later, when the need is greater. The group is building a system that will steer surplus electricity generated by a nearby wind farm to a big air compressor. Connected to a deep well, the compressor pumps air into layers of sandstone. Some 3,000 feet down and sealed from above by dense shale, the porous sandstone acts like a giant balloon. Later, when demand for power rises, this flow is reversed.

CHEERLEADERS for renewable energy are fond of pointing out that patches of desert receive enough energy each year from sunlight to power the entire world. But few deign to explain how the construction of the millions of solar cells required to convert that energy into electricity would be financed. Utility bosses and policymakers tend to dismiss wind and solar power as noble but expensive distractions, sustainable only through lavish subsidies. But new studies suggest that renewables might not be as dear as sceptics suspect...These figures, of course, rely on all sorts of questionable assumptions.

Wind turbine manufacturer Clipper Windpower tumbled from recent highs today after it announced an issue relating to machining tolerances in its gearboxes and a short delay in turbine deliveries. As a result of the issue, the group said it has decided to introduce an additional measurement process during machining to ensure gearbox tolerances are met.

Clipper Windpower Plc, the partner of BP Plc in U.S. wind-energy projects, fell to an 11-month low in London trading because a faulty component will lead to a delay in shipments. ...Production of Clipper's 2.5-megawatt Liberty wind turbine has been hampered by problems relating to the supply of externally-sourced components. The company forecast a first-half loss after turbine production was ``constrained'' by difficulties in obtaining parts. ``They have slipped up on quality issues twice,'' said John-Marc Bunce, an analyst at London-based Ambrian Partners Ltd. ``This could potentially be damaging to their sales ability going forward.'' Bunce lowered his recommendation on Clipper to ``sell'' from ``hold.''

The largest wind turbine manufactured in the United States is running into some technical difficulty. Clipper Windpower Inc.'s 2.5-MW Liberty wind turbines at the 20-MW Steel Winds facility in Lackawanna, N.Y., are malfunctioning due to faulty gear sets. "At first, we were receiving great performance from the turbines," said Michael Alvarez, executive vice president and COO of UPC Wind Partners LLC, which co-owns the facility with BQ Energy LLC. "Over the summer, a gear-timing issue in the drive train's secondary stage was detected in some of Clipper Windpower's Liberty wind turbines at the Steel Winds site. The cause was found to be a supplier quality deficiency in the drive train attributable to the suppliers' manufacturing process. As part of Clipper's warranty, upgraded drive trains will be installed into all eight turbines at the Steel Winds site. Currently, two turbines are in operation."
