The folks over at NREL have compiled a map that shows the wind power capacity of each state. Minnesota ranks very well! If you have ideas about where a project would be well-suited, maybe you should let them know. Take a look at the database they are compiling – see if you can contribute.
New Database Assists with Wind Project Siting – November 22, 2011
The U.S. Department of Defense and the Natural Resources Defense Council created the Renewable Energy and Defense Geospatial Database, a mapping and analytic tool to help project developers identify possible barriers to a proposed project location, including nearby military bases, radar installations, missile silos, and flight paths. The database also shows endangered or threatened wildlife species near the proposed project site. The system will be free to developers if they sign a licensing agreement with the Natural Resources Defense Council.
Also – hear some thoughts on how wind power projects can help farmers save their land. VanderVeen has seen the benefits of wind energy development first-hand in Michigan where one wind energy project has saved thousands of acres of farmland for future generations but also provided a boost to manufacturing that has helped the state weather the economic downturn.

The German manufacturer has big plans for its renewable energy business, even in the United States, with its fickle winds.
By JACK EWING, New York Times | Last update: January 13, 2011 – 5:06 PM
FRANKFURT – A reader of the annual report of Siemens, the German engineering giant, could easily get the idea that the company was investing in wind energy because management wants to save the planet.
“All our actions and decisions are informed by the principle of sustainability,” Siemens said in the introduction to its 2010 report, a few pages after the obligatory photograph of the chief executive, Peter Löscher, and the rest of the management board.
In smaller type on Page 90 is the fact that clean energy is a big moneymaker for Siemens. The renewable energy division, which consists mostly of the wind power business, recorded a bigger sales increase than any other unit in the quarter ended Sept. 30, rising 48 percent, to $1.3 billion. New orders rose 85 percent.
Still, the unit’s operating profit margin of 10.6 percent lagged that of more conventional businesses, like providing equipment for fossil-fuel power plants, and fell short of Siemens’ goal of a 12 percent to 16 percent margin. The unit accounted for about 5 percent of the total yearly profit for Siemens, whose array of products includes trains, factory equipment and X-ray machines.
But like any fast-growing business, there is also risk. The North American market has slumped just as Siemens, which does most of its manufacturing in Denmark, is stepping up investments in the United States and Canada.
On Dec. 3, Siemens opened a factory in Hutchinson, Kan., to make nacelles — housings the size of a bus that sit atop wind turbine towers and hold the mechanical and generating equipment. Siemens already has a blade factory in Fort Madison, Iowa, which opened in 2007, and is planning a plant in Tillsonburg, Ontario, to supply blades for nearby wind farms.
The company’s goal is to become one of the top three suppliers of wind power equipment in the world, up from eighth or ninth now. Vestas Wind Systems, a Danish company that focuses solely on wind power, is the market leader.
To have any chance, however, requires a foothold in China, the world’s largest market for wind power, and one of the most difficult to enter because of government policies that favor local companies. In November, Siemens opened a factory in Shanghai, a city chosen in part because it is on the water and a good place from which to ship equipment for offshore wind parks, a niche in which Siemens is the No. 1 equipment supplier.
The Asian market is the largest and fastest-growing for wind power, accounting for an estimated 44 percent of global capacity, according to IHS Emerging Energy Research. Europe is second, with 34 percent of global capacity, and North America third, with 19 percent.
Siemens is also planning factories in the emerging markets of India and Russia as well as in Britain where, despite an austerity budget, the government is strongly backing the development of offshore wind projects.
In the United States, makers of wind power equipment have had to contend with fickle government incentives and a plunge in the price of natural gas, which made wind energy less competitive. In addition, the financial crisis has made it harder for smaller operators to get loans to build wind parks.
“The U.S. was supposed to be one of the most attractive markets,” said Eduard Sala de Vedruna, a research analyst for wind power at IHS Emerging Energy Research. “It’s not going to be as attractive as it used to be.”
Like General Electric, the market leader in wind power in the United States, Siemens may have an advantage against upstarts because it has long supplied equipment for conventional power plants and transmission facilities run by big utilities. Siemens also has a long history in countries like Russia and China, where the company sold telegraph equipment as early as 1872.
“Siemens already had some good relationships,” Sala de Vedruna said. “They understand the business of generating electricity.”
In a measure of how wind has become mass-market, the Kansas factory will feature a moving assembly line, like an auto factory. In older factories, designed when volumes were lower, the units were assembled in place, a less efficient method. The assembly line cuts the time it takes to build a nacelle to 19 hours from 36, according to Siemens.
Sala de Vedruna said that he thought the long-term prospects for wind power in the United States were still bright. Siemens apparently agrees — and wants to get closer to the customer.
“America is for us still the single largest market,” said René Umlauft, chief executive of Siemens Renewable Energy. Wind turbine components “are large and heavy, and it costs money to move them from one place to another.”
Siemens got into the wind business only in 2004, when it acquired a maker of wind turbines in Brande, Denmark, which remains the headquarters of the wind unit. Watching that business expand seems to have given Siemens an appetite for other investments in renewable energy.
In 2009, Siemens acquired Solel, an Israeli company that makes components for plants that use concentrated heat from the sun to generate power. And last February, Siemens got a minority stake in Marine Current Turbines, a British firm that makes equipment for generating electricity from ocean tides.
These technologies are still years from mass deployment. But, Umlauft said, “we want to do the same thing that we did in wind.”

In the southwest Minnesota city of Pipestone, the last of 110 workers laid off from the Suzlon wind-turbine blade factory walk out the door this week, all but shuttering the plant.
Just 200 miles to the northwest, in Aberdeen, wind-turbine blade maker MFG South Dakota has a completely different problem: It needs up to 40 more workers and managers to boost its workforce to about 400.
And at the Siemens turbine-blade factory in Fort Madison, Iowa, employment has grown to 700, up by 100 workers since President Obama visited the plant in April to promote renewable energy.
The stark differences among the three Midwestern manufacturers show how business can blow hot and cold in what is still a young and growing wind-power industry.
“We are actually ramping up to production,” said Dave Giovannini, general manger of the MFG Aberdeen plant, which employs 361 workers and has been operating for three years. “We will be moving to a new blade version early next year, and we have our year pretty much booked at this point.”
MFG South Dakota, a unit of the privately held, Ohio-based Molded Fiber Glass Cos., builds blades for GE Energy’s 1.5- and 1.6-megawatt wind turbines, which this year outsold Suzlon models more than 2-to-1 in the United States, according to American Wind Energy Association data.
On Tuesday, Siemens announced its largest onshore wind-turbine order ever — for 248 2.3-megawatt units to be installed at three MidAmerican Energy Co. projects in Iowa. The blades — three per unit — will be manufactured at the Fort Madison plant in southeast Iowa, the company said in a statement.
Meanwhile, Suzlon Energy Ltd. isn’t profitable. Brad Wiggins, the India-based company’s regional manager in Minnesota, informed Pipestone city officials last month that the Suzlon Rotor Corp. plant would scale back to 33 workers because it had booked no orders for blades. Wiggins has declined to comment, but Pipestone officials say Suzlon is developing new blade technology and seeking orders.
No one’s moving — yet
One consequence of the layoff is that a Minnesota-funded assistance program has been placed in the unusual position of offering information to the 110 laid-off Suzlon employees about job opportunities in South Dakota. The two states have long competed to attract employers.
So far, none of the recently laid-off Suzlon workers has been hired by MFG South Dakota. The Aberdeen company, at its own expense, plans to hold a job fair in Pipestone early next year, hoping to attract experienced Suzlon workers.
Yet it may be hard to persuade former Suzlon workers to move from the Pipestone area because many own homes and have spouses with jobs.
“If you have one person working and one not working, they are not going to put all their eggs in one basket and leave to go to work up in Aberdeen,” said Linda McCorquodale, who works for a nonprofit organization that manages the Minnesota worker assistance program.
Giovannini, the manager of the MFG plant, said it has 25 to 30 production job openings and seven to 10 engineering and supervisory openings. The production worker pay scale is $12.50 to $22 an hour, he said. The company currently does not pay relocation costs for non-supervisory jobs, he added.
The unemployment rate in Aberdeen is 3.6 percent, far below the national rate of 9.8 percent and Minnesota’s rate of 7.1 percent.
“I wouldn’t describe it as a worker shortage, but we have created more jobs, and it does require us to do some recruitment,” said Julie Johnson, former South Dakota secretary of labor who now heads the Absolutely! Aberdeen economic development group.
GE’s successful turbine
One reason for the success of the Aberdeen plant is that it builds blades for GE’s most popular wind turbine.
“With more than 14,500 installed globally, GE’s 1.5-megawatt series wind turbines are the most widely deployed wind turbines in the world,” said company spokeswoman Milissa Rocker in an e-mail.
In Minnesota, for example, 147 GE 1.5-megawatt wind turbines were being installed this year, most of them at a large wind farm in Nobles County that owner Xcel Energy announced Tuesday is fully operational. By comparison, just 10 Suzlon turbines were installed this year.
Unlike Suzlon, which built its Pipestone blade factory in 2006, GE relies on outside firms to build its blades. Moulded Fiber Glass Cos. is a major supplier of fiberglass components. In 1953, the company built the original Corvette fiberglass bodies, and now has nine North American plants making composite products for a range of uses.
Earlier this year, GE and Suzlon reported major declines in their U.S. wind businesses, though GE said its was still profitable. Now, Rocker said, GE is “seeing new orders, due in large part to supportive policies and renewable energy goals,” including the one-year extension of a federal program that offers upfront cash grants in lieu of tax credits.
Siemens, based in Germany but with an expanding U.S. presence, said Tuesday that the outlook is positive. Siemens manufactures its own blades, using a patented, seamless technology with no glue joints that can become weak points, the company said.
Suzlon, whose sole business is wind power, reported a 2009 loss of $207 million and another $276 million in losses during the first three quarters of this year. During that period, Suzlon spent an estimated $100 million repairing blades under warranty after some of them developed cracks.
In the past three months, nine of 17 stock analysts that track Suzlon recommended that investors sell its stock, according to Bloomberg. Religare Institutional Research, based in Mumbai, India, said in a November report that the break-even point for Suzlon is “a distant dream.”

University of Colorado at Boulder | December 16, 2010
Wind turbines in Midwestern farm fields may be doing more than churning out electricity. The giant turbine blades that generate renewable energy might also help corn and soybean crops stay cooler and drier, help them fend off fungal infestations and improve their ability to extract growth-enhancing carbon dioxide from the air and soil.
The preliminary findings of a months-long study that examines how wind turbines on farmlands interact with surrounding crops were presented today at the annual fall meeting of the American Geophysical Union in San Francisco. The presentation was made by researcher Gene Takle of the U.S. Department of Energy’s Ames Laboratory and Julie Lundquist, assistant professor in the University of Colorado at Boulder’s atmospheric and oceanic studies department.
“We’ve finished the first phase of our research, and we’re confident that wind turbines do produce measureable effects on the microclimate near crops,” said agricultural meteorology expert Takle, who also is the director of the Climate Science Program at Iowa State University.
According to Takle, turbine blades channel air downward, in effect bathing the crops below with the increased airflow they create.
“Our laser instrument could detect a beautiful plume of increased turbulence that persisted even a quarter-mile downwind of a turbine,” said Lundquist, who also is a joint appointee at the U.S. Department of Energy’s National Renewable Energy Laboratory, and a fellow of the Renewable and Sustainable Energy Institute, a joint institute of CU-Boulder and NREL.
Lundquist’s team uses a specialized laser known as lidar to measure winds and turbulence from near the Earth’s surface to well above the uppermost tip of a turbine blade.
Both Lundquist and Takle stressed their early findings have yet to definitively establish whether or not wind turbines are beneficial to the health and yield potential of soybeans and corn planted nearby. However, their finding that the turbines increase airflow over surrounding crops suggests this is a realistic possibility.
“Because wind turbines generate turbulence and the mixing of air downwind, they may accelerate the natural exchange processes between crops and the lower part of the atmosphere,” said Lundquist.
For example, the sun warms crops and some of that heat is given off to the atmosphere. Extra air turbulence likely speeds up this heat exchange, so crops may stay slightly cooler on hot days, Lundquist said. On cold nights, the turbulence created by the wind turbines stirs the lower atmosphere and keeps nighttime temperatures around the crops warmer.
“In both the spring and in the fall, we suspect that turbines’ effects are beneficial by warming and perhaps preventing a frost, thus extending the growing season,” said Lundquist.
Wind turbines also may have positive effects on crop moisture levels. Extra turbulence may help dry the dew that settles on plants, minimizing the amount of time fungi and toxins can grow on plant leaves. Additionally, drier crops at harvest help farmers reduce the cost of artificially drying corn or soybeans.
Another potential benefit to crops is that increased airflows could enable corn and soybean plants to more readily extract CO2, a needed fuel for crops, from the atmosphere and the soil, thus helping the crops’ ability to perform photosynthesis.
Takle’s wind turbine predictions are based on years of research on so-called agricultural shelter belts, which are rows of trees in a field designed to slow high-speed natural winds.
“In a simplistic sense, a wind turbine is nothing more than a tall tree with a well-pruned stem,” said Takle. “For a starting point for this research, we adapted a computational fluid model that we use to understand trees, but we plan to develop a new model specific to wind turbines as we gather more data.”
The team’s initial measurements consisted of visual observations of wind turbulence upwind and downwind of the turbines. The team also used wind-measuring instruments called anemometers to determine the intensity of the turbulence. The bulk of the wind-turbulence measurements and the crop-moisture, temperature and CO2 measurements took place in the spring and summer of this year.
“We anticipate the impact of wind turbines to be subtle, but in certain years and under certain circumstances the effects could be significant,” said Takle. “When you think about a summer with a string of 105-degree days, extra wind turbulence from wind turbines might be helpful. If turbines can bring the temperature down below 100 degrees that could be a big help for crops.”
The CU-Boulder and ISU teams hope to continue their measurements throughout the next growing season.
“These data are quite encouraging, and we look forward to collecting more data to ensure the certainty of these results,” said Lundquist. “As wind energy expands in future years to provide a domestic source of energy, we’ll need robust measurements to understand and predict the impacts of that expansion.”
The research was funded or supported by Ames Laboratory, the Department of Energy’s Office of Energy Efficiency and Renewable Energy, the U.S. National Laboratory for Agriculture and the Environment, CU-Boulder and NREL.

TIANJIN, CHINA – Judging by the din at its factory here one recent day, the Spanish company Gamesa might seem to be a thriving player in the Chinese wind energy industry it helped create.
But Gamesa has learned the hard way, as other foreign manufacturers have, that competing for China’s lucrative business means playing by house rules that are often stacked in Beijing’s favor.
Nearly all the components that Gamesa assembles into million-dollar turbines here, for example, are made by local suppliers — companies Gamesa trained to meet onerous local content requirements. And these same suppliers undermine Gamesa by selling parts to its Chinese competitors — wind turbine makers that barely existed in 2005, when Gamesa controlled more than one-third of the Chinese market.
But in the five years since, the upstarts have grabbed more than 85 percent of the wind turbine market, aided by low-interest loans and cheap land from the government, as well as preferential contracts from the state-owned power companies that are the main buyers of the equipment. Gamesa’s market share now is only 3 percent.
With their government-bestowed blessings, Chinese companies have flourished and now control almost half of the $45 billion global market for wind turbines. The biggest of those players are now taking aim at foreign markets, particularly the United States, where General Electric has long been the leader.
The story of Gamesa in China follows an industrial arc traced in other businesses, like desktop computers and solar panels. Chinese companies acquire the latest Western technology by various means and then take advantage of government policies to become the world’s dominant, low-cost suppliers. It is a pattern that many economists say could be repeated in other fields, like high-speed trains and nuclear reactors, unless China changes the way it plays the technology development game — or is forced to by its global trading partners.
Companies like Gamesa have been so eager to enter the Chinese market that they not only bow to Beijing’s dictates but have declined to complain to their own governments, even when they see China violating international trade agreements.
Even now, Gamesa is not crying foul — for reasons that are also part of the China story. Although the company’s market share in China has atrophied, the country’s wind turbine market has grown so big, so fast that Gamesa now sells more than twice as many turbines in China as it did when it was the market leader five years ago.
“If we would not have done it, someone else would have done it,” said Jorge Calvet, Gamesa’s chairman and chief executive.
Gamesa, an old-line machinery company that entered the wind turbine business in 1994, is a modern Spanish success story. With sales of $4.4 billion last year, it is the world’s third-largest turbine maker, after Vestas of Denmark, the longtime global leader, and GE.
With its relatively low Spanish labor costs, Gamesa became an early favorite a decade ago when China began buying significant numbers of imported wind turbines, as Beijing started moving toward clean energy.
But Chinese officials had begun to slip new provisions into the bidding requirements for some state-run wind farms, requiring more and more of the content of turbines to be equipment produced within China — not imported. Those piecemeal requirements soon led to a blanket requirement. On July 4, 2005, China’s top economic policy agency passed Notice 1204 that declared wind farms had to buy equipment in which at least 70 percent of the value was domestically manufactured.
Trade lawyers say that setting any local content requirement — let alone one stipulating such a high domestic share — was a violation of the rules of the World Trade Organization, the international body that China had joined just four years earlier.
It was not until the summer of 2009, when senior Obama administration officials started looking at barriers to U.S. clean energy exports, that the United States pressed China hard about Notice 1204. The Chinese government revoked it two months later.
But by then, the policy was no longer needed. Some Gamesa wind turbines exceeded 95 percent local content.
Ready to export
The Chinese government is now slowing the approval of new wind farms as it gives its national electricity system time to absorb thousands of new turbines that have already been erected and not yet connected to the grid.
The government policy means that Chinese turbine makers must now look beyond their captive national market for further growth.
Sinovel, China’s biggest wind turbine maker, has said it wants to become the world’s largest by 2015. Sinovel is among the Chinese companies now opening U.S. sales offices in preparation for a big export push next year. They are backed by more than $13 billion in low-interest loans from Chinese government-owned banks and billions more are being raised in initial public offerings.
Multinationals are alarmed. Vestas, for example, is closing four factories in Denmark and one in Sweden, and laying off one-eighth of its 24,000-person labor force, in an effort to push its costs down closer to Asian levels.
The provincial government of Ontario in Canada now wants to take a page from China’s playbook by trying to require 25 percent local content for wind energy projects and 50 percent for solar power projects in the province. The Japanese government responded by filing a WTO complaint against Canada in September, asserting that Ontario was violating the WTO prohibition on local content requirements. By contrast, Japan has never filed a WTO complaint on any issue against China, for fear of harming diplomatic relations with its large neighbor.

 Dan Juhl pointed out how the unique geography of the Buffalo Ridge area of Minnesota makes it ideal for wind generation. | Photo by Glen Stubbe, Dml - Star Tribune Star Tribune
By DAVID SHAFFER, Star Tribune | Last update: December 11, 2010 – 10:51 PM
Dan Juhl has been developing wind farms for three decades.
He built Minnesota’s first wind energy project in 1986 on Buffalo Ridge, and his company Juhl Wind Inc., based in Woodstock, Minn., now specializes in developing smaller projects, typically 20 megawatts or less. Juhl Wind has reported an increase in revenues, with wind projects under construction in Meeker, Murray and Winona counties.
But the U.S. wind industry expects to install about half the capacity this year as it did in 2009. In an interview with the Star Tribune, Juhl, who is the company’s chairman and CEO, talked about the issues facing the wind energy industry and what the future holds.
Q Wind power this year took a downturn, with a decline in U.S. installations after five years of growth. What’s going on?
A One of the biggest factors … has been the fact that the transmission system is reaching a limit for big projects. The system was not designed to take large amounts of power injected at certain places, and wind energy is reaching that limit. And also there are issues with the financial markets. In 2008, the system basically collapsed for financing, and everybody’s trying to get back on their feet …. As you move wind development away from areas where there’s no people, where the transmission capacity has been consumed, and you try to move them closer to the load centers, where there are a lot of people, you run into permitting issues because of the large amounts of land that are required to do a large wind farm. So all these things are weighing on the industry.
Q Minnesota is one of the leading wind-energy states, with 9 percent of power from wind. What are the prospects for adding to that?
A I think the further development in Minnesota is going to have to be more community-based and smaller projects doing distributed generation until the transmission system is upgraded.
Q Your company has focused on developing wind farms owned by communities, co-ops or landowners. How many have you built and how many are planned for the future?
A We have 17 projects in the ground, … four projects in construction, and then we have at least a dozen projects in development.
Q Has Juhl Wind’s smaller-scale, community approach been affected by the downtown in the wind market?
A Yes and no. We had four projects in construction this year, which is probably four times more than most companies have in construction. And we do have projects that are scheduled to go in the ground next year.
Q Your company reported that revenues increased significantly this year, but did not report a profit. Why is that?
A There is a bit of chasing your tail in this business …. From the time you start to develop a project you are talking three or four years. So you are putting money in — you’re putting in construction and you are rolling revenue and revenue is moving, but the time when you get your profit out of it is at the end of the project. We feel our company is very sound and we have profits that are coming in, and it just takes time to roll it all through the process.
Q One of Minnesota’s major wind energy players, Suzlon, plans to lay off most workers at its turbine blade plant in Pipestone, Minn., because of no orders. Do you think that plant will get back on feet?
A I think so. It’s all relative to how the market can rebound. But they produce a good product out of the Pipestone plant, and as long as Suzlon is able to move turbines, they will be putting blades out of there. But I have no prediction on how the turbine manufacturers are going to handle this slowdown.
Q Do you think wind power will ever compete on its own without government incentives?
A The tax credit that wind energy gets is minuscule in comparison to the subsidies that fossil fuels — oil and coal — and nuclear power get. Just go into the Federal Register and look at the subsidies those energy resources have gotten over the years and what they still get today in comparison to renewable energy. It is an overwhelming difference.
You have to remember the cost of wind energy and renewable energy, solar power too, is the cost of the capital to buy the technology. You have no fuel, you have no emissions, you have no waste, you have no transportation of fuel, you have none of the things that keep driving energy costs up and up and up. So if you eliminated all subsidies for all energy, renewable energy would by far and away be the best value for the American people.

On the same day that Suzlon Group decided to shut its wind turbine blade plant in Pipestone, Minn., city officials in Jonesboro, Ark., were glowing from Friday’s grand opening of a $40 million wind turbine manufacturing plant by Denmark-based Nordex.
Some of the woes that led to Suzlon’s announcement on Monday, most notably a series of quality-control issues with its blades, were self-inflicted. Still, the parallel universes of a shutdown in one state and a ribbon-cutting in another illustrate the schizoid reality for alternative energy in the United States: great promise and great peril.
In terms of potential, few markets represent as large an opportunity for alternative energy. The United States relies on coal for nearly half our electricity, and we import more than half our crude oil. Coal is plentiful but dirty. Oil is a diminishing resource controlled by many people who don’t like us.
Europe gets about 5 percent of its energy from wind, and in some countries the total is 10 percent or more. China, meanwhile, is investing heavily to double wind capacity.
In the United States, we get only about 2 percent of our electricity from the wind, which makes this potentially “one of the biggest wind energy markets in the world,” Nordex said at the grand opening last week.
But with no energy policy, the future for wind, solar and other energy technologies depends, to a certain degree, on how well those interests can work the halls of Congress.
To date, things aren’t going so well in this department. President Obama has called for 25 percent of the nation’s electricity to come from renewable sources by 2025, but efforts to establish federal mandates have failed so far. Despite fierce lobbying by industry proponents, wind and solar energy are caught in the political maw of climate change and cap-and-trade legislation.
As a result, some of the tax breaks and other incentives that spurred massive wind power development in 2009 will expire at the end of this year. That uncertainty has many firms reluctant to commit to new projects.
Juhl Wind Inc. of Woodstock, Minn., has four projects under construction but only one contracted for next year. Eden Prairie-based Wind Energy America Inc. has 15 projects under development, but is actively pushing only three at the moment. “Unless you break ground this year, you don’t qualify for the tax credit,” said Wind Energy CEO Mel Wentz.
The free marketers out there will say that industries should be able to breathe on their own rather than rely on the iron lung of government incentives and tax credits.
Fair enough, but let’s apply that same rationale to the oil and natural gas industries. According to a Treasury Department estimate, just a handful of tax credits for those industries cost the U.S. Treasury about $3 billion in lost tax revenue annually.
Or how about the ethanol industry, which has been able to command a trifecta of mandates, trade tariffs and producer price credits — all in the names of jobs and energy independence? The tax credit alone was worth an estimated $4.7 billion last year. Extending the tariff, which is set to expire at the end of 2010, has drawn the support of a broad swath of legislators, some of whom have opposed incentives for the solar and wind industries.
“Let’s make it a totally free market for everyone and then see what happens,” said Dan Juhl, CEO of Juhl Wind.
Wind and solar certainly aren’t the answers to all our energy needs. Transmission remains a tricky and potentially expensive proposition, and neither technology will reduce our dependence on foreign oil, since very little oil is used in the production of electricity.
“I’m not as die-hard as some wind advocates, who believe it is the answer to all our problems,” said Wentz, who was an executive with a Texas utility before he joined Wind Energy. “Its like your 401(k) or investment portfolio. You want to make sure you’re diversified.”
Twenty-eight states, including Minnesota, now have a renewable electric standard. This patchwork arrangement will not spur the innovation that will, ultimately, lead to lower prices for these emerging technologies. It’s time for Congress to stop huffing and puffing and invest in our future.

NEW YORK — The first mass-market electric cars go on sale next month, and the nation’s electric utilities couldn’t be more thrilled — or worried.
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.
Not since air conditioning spread across the country in the 1950s and 1960s has the power industry faced such a growth opportunity. Last year, Americans spent $325 billion on gasoline, and utilities would love even a small piece of that market.
The main obstacles to wide-scale use of electric cars are high cost and limited range, at least until a network of charging stations is built. But utility executives fret that difficulties keeping the lights on for the first crop of buyers–and their neighbors–could slow the growth of this new niche.
“You never get a second chance to make a first impression,” says Mike Rowand, who is in charge of electric vehicle planning at Duke Energy.
Auto executives say it’s inevitable that utilities will experience some difficulties early on. “We are all going to be a lot smarter two years from now,” says Mark Perry, director of product planning for Nissan North America.
Electric cars run on big batteries that are charged by plugging into a standard wall socket or a more powerful charging station. A combined 30,000 Nissan Leafs and Chevrolet Volts are expected to be sold over the next year. Over the next two years, Ford, Toyota and every other major automaker also plan to offer electric cars.
Governments are promoting the expensive technology as a way to reduce dependence on foreign oil, cut greenhouse gas emissions and improve air quality. Congress is offering electric car buyers a $7,500 tax credit and some states and cities provide additional subsidies. The Leaf sells for $33,000; the Volt sells for $41,000.
Electric cars produce no emissions, but the electricity they are charged with is made mostly from fossil fuels like coal and natural gas that do. Still, electric cars produce two-thirds fewer greenhouse gas emissions, on average, than a similarly sized car that runs on gasoline, according to the Natural Resources Defense Council.
Driving 10,000 miles on electricity will use about 2,500 kilowatt-hours, or 20 percent more than the average annual consumption of U.S. homes. At an average utility rate of 11 cents per kilowatt-hour, that’s $275 for a year of fuel, equivalent to about 70 cents per gallon of gasoline.
“Electric vehicles have the potential to completely transform our business,” says David Owens, executive vice president of the Edison Electric Institute, a trade group.
Vehicle clusters
Nationwide, utilities have enough power plants and equipment to power hundreds of thousands of electric cars. Problems could crop up long before that many are sold, though, because of what utilities call “clustering.”
Electric vehicle clusters are expected in neighborhoods where:
• Generous subsidies are offered by states and localities.
• Weather is mild, because batteries tend to perform better in warmer climates.
• High-income and environmentally conscious commuters live.
Adding an electric vehicle or two to a neighborhood can be like adding another house, and it can stress the equipment that services those houses.
“We’re talking about doubling the load of a conventional home,” says Karl Rabago, who leads Austin Energy’s electric vehicle-readiness program. “It’s big.”
How big depends on the size of the battery, and how fast the car is charged.
When plugged into a standard 120-volt socket, the electric car will draw 1,500 watts. By comparison, a medium-sized air conditioner or a countertop microwave oven will draw about 1,000 watts.
But the car can be charged faster, and therefore draw more power, when plugged into a home charging station. The first Leafs and Volts can draw 3,300 watts, and both carmakers may boost that to 6,600 watts soon. The Tesla Roadster, an electric sports car with a huge battery, can draw 16,800 watts. That’s the equivalent of 280 60-watt light bulbs.
A modest home in the San Francisco Bay area that doesn’t need air conditioning might draw 3,000 watts at most.
Transformers that distribute power from the electrical grid to homes are often designed to handle fewer than a dozen homes. Extra stress on a transformer from one or two electric vehicles could cause it to overheat and fail, knocking out power to the block.
The “nightmare” scenario, according to Austin Energy’s Rabago: People come home from work on a hot afternoon, turn on the air conditioner and the plasma television, blend some frozen cocktails, start cooking dinner on an electric stove –and plug their car into a home charging station.
An electric vehicle plugged into a standard wall socket poses a different problem. It will put less stress on a transformer, but it could trip a circuit breaker if the circuit serves other appliances. Power would go off in part of the house.
To head off problems, utilities are gathering information from Nissan and Chevrolet, doing customer surveys and looking at buying patterns of hybrid gas-electric cars like the Toyota Prius to try to predict where they might see clusters of electric car buyers.
Utilities also hope to persuade drivers to program their cars to charge late at night, when rates are low and most appliances are switched off.

With the increased visibility of wind turbines on the landscape over the last few years, some people have raised concerns over the various impacts these machines might have. Recently the Star Tribune published a letter from concerned citizen Gary Carlson, who is apparently convinced that the inaudible, low-frequency vibrations produced by the machines pose a significant health risk. Indeed, a number of people afflicted with a variety of symptoms attribute their suffering to wind turbines, and there is a book that makes the claim Carlson takes up.
It is also true that in the past, just as in the present, and just as for every other industry, scam artists and ill-informed practitioners created bad experiences. Poorly built or improperly sited machines certainly produce unfortunate consequences.
But the scientific research into the impact of low-frequency vibrations on health does not corroborate Carlson’s claim. In 2009, the Minnesota Department of Public Health released a report on the public health impacts of wind turbines. The researchers had difficulties analyzing infrasonic impacts, because there is no scientific consensus on how to measure low-level frequency. The problem seems to be one of distinguishing the simultaneous vibrations of wind blowing through the trees from the infrasonic vibrations of turbines. Infrasonic vibrations from turbines appear to be no different than infrasonic vibrations found elsewhere in the environment.
Similar findings, and exposure of the unscientific methods of the main proponent of Carlson’s claim, are in two other reports on the topic. One is by Dr. W. David Colby, the Chatham-Kent Medical Officer of Health and an associate professor at the University of Western Ontario’s Schulich School of Medicine and Dentistry. The other is by Geoff Leventhall, who has a doctoral degree in physics and is a consultant on matters related to noise vibration and acoustics in the United Kingdom.
These researchers find no scientific evidence whatsoever for a causal link between the low-frequency vibrations from wind turbines and health. They do not dispute the real suffering that some people report, but history is full of cases where people have incorrectly identified the cause of their suffering.
(The Colby and Leventhall reports can be viewed in a webinar available at windustry.org/wind-turbine-syndrome-myths-and-facts-webinar.)
No one should be under any illusion that utility-scale wind turbines do not change the landscape. They are multimillion-dollar power plants hundreds of feet high (though, in the case Carlson refers to, the turbines in question are not 400 feet high). Wind turbines of this sort typically fit very well into a rural, agricultural landscape, with no significant impact on the agricultural use of the land and significant positive economic impacts on the community.
By contrast, our use of fossil fuels causes extensive environmental damage, such as death to our lakes from acidification and dramatic increases in the mercury content of our fish to the point where advisories against eating them are common. The serious, scientifically proven negative health effects caused by the use of fossil fuels are staggering: black lung disease, mining disasters, explosions, mercury poisoning, exacerbation of a wide variety of illnesses — the list goes on.
Windustry, a national nonprofit that advocates for community-owned wind energy, properly sited turbines and community involvement in wind-resource development, is holding a conference today and Tuesday in St. Paul. It will feature recognized experts in all aspects of the wind industry, and is intended for anyone with an interest in wind development in their community. Information is on our website, www.windustry.org.

Offshore wind turbines could be sited in deeper water, closer to the shore off the U.K. coast to take advantage of stronger, more consistent wind speeds, according to the Energy Technologies Institute (ETI).
Project Deepwater, a consortium led by Blue H with BAE Systems, the Centre for the Environment, Fisheries and Aquaculture, EDF, Romax Technology Ltd., SLP Energy and PAFA Consulting Engineers, looked at the feasibility and costs of generating electricity using offshore wind turbines mounted on a floating, tension-legged platform in water between 70 meters to 300 meters deep.
“The cost of foundations does get more expensive as you go into deeper water, but the wind speeds in much of the [deep water in the U.K.] are significantly stronger and more consistent, which results in a more reliable and higher energy output,” says David Clarke, chief executive of ETI. “Over time, this more than outweighs the additional foundation costs and gives an overall lower cost of energy.”
Project Deepwater was one of the ETI’s first offshore wind projects along with Nova and Helm Wind, which are due to produce final conclusions later in the year.
The Nova project is looking at the potential benefits of using an innovative vertical-axis turbine, and Helm Wind is assessing the complete design system for an offshore wind turbine array, including installation, design, aerodynamics, electrical systems, control and maintenance.
The findings from all three projects will be analyzed by the ETI before a decision is made on the next steps in the offshore wind program, which could have an offshore wind demonstrator built using technologies and insights from all three projects.
