Study Says Bigger Renewables Not Always Better

Photo Source: National Renewable Energy Laboratory

A thought-provoking new study by the Institute for Local Self-Reliance (ILSR) has found that locally-owned renewable energy projects generally hold more local economic benefits than large-scale ones.

The “Economies and Diseconomies of Scale” concludes that bigger is not always better. The Minneapolis-based ILSR analyzed the costs and return of wind power and ethanol, both major renewable energy sources in the Upper Midwest. While they are both less expensive to produce on a large scale, the costs of having to transmit the energy across long distances can negate those savings. That, coupled with the fact that large projects are generally owned by corporate or out-of-state interests, makes smaller, local projects more beneficial for the immediate community.

ILSR recommends that states follow Minnesota’s example, where law provides a favorable tariff for locally owned renewable energy projects, requires 51 percent ownership by Minnesota residents, and designates 51 percent of financial benefits to local owners. In addition, the federal production tax credit (PTC) for wind should be changed to allow it to be taken against ordinary income rather than only applying to passive income (such as from rent). This would allow greater access to the tax credit and open it up to more individuals to be renewable energy investors.

A carbon-constrained world presents us with many options for change. Do we want to create – and is it realistic – a totally new energy system, one that is locally owned, producing energy for the local area, with the majority of economic benefits going to the local community? Or does the urgency of global warming demand as much renewable energy as possible, as fast as possible, owned by whomever possible?

U.S. House Wraps Up Energy Bill

The big news this week was that the U.S. House passed an energy bill that for the first time included a federal renewable energy standard (RES). This RES – an amendment to the energy bill sponsored by Representatives Tom Udall (D-NM) and Todd Platts (R-PA) – requires utilities to get 15 percent of their power from renewables by the year 2020. Other components of the House energy bill include:

  • Moving $16 billion in tax incentives away from oil companies and putting it towards renewable energy.
  • New energy efficiency standards for appliances and building codes.
  • The creation of a Solar Energy Industries Research and Promotion Board to raise national awareness of solar energy options. The program would be funded completely by a portion of solar industry revenues, with no appropriations authorized.
  • A modified 4-year extension of the wind power Production Tax Credit (PTC) that limits the credit to 35 percent of wind project costs.

Not in the bill is an increase in the Corporate Average Fuel Economy (CAFÉ) standards (a.k.a. “fuel efficiency”) that was a hot topic as the session came to a close. By avoiding a vote on CAFE standards, Democrats avoid public in-fighting with fellow Dems from auto industry states, notably Commerce Committee Chairman John Dingell (D-MI).

The Senate already approved an increase in fuel efficiency back in June, which will be just another piece of the Senate bill to be reconciled with the House version in conference committee this fall. In addition, the White House has threatened to veto any legislation containing a renewable energy standard.

Weekend Web Review: Power of Wind

Renewable energy was in the spotlight during this last week of Congress. The Udall-Platts amendment to the House energy bill calls for a renewable portfolio standard (RPS, sometimes also called a “renewable energy standard”) that would require the nation’s utilities to get 15 percent of their energy from renewable sources by 2020. But it failed to get a vote yesterday because of computer problems with the voting system and a dispute over a vote on an agricultural bill. However House Speaker Nancy Pelosi vowed that the amendment would be taken up today.

An RPS is a key policy tool to create a reliable renewable energy market in this country. In fact, the American Wind Energy Association (AWEA) was spurred to create a new website called the Power of Wind to educate readers about wind power and why an RPS – and the Udall-Platts amendment in particular – is so important.

Besides information, the Power of Wind gives the reader suggestions of actionable items to promote wind power. Learn how to contact your elected official on specific wind energy legislation or tell a friend about the issue. AWEA also has an impressive new TV ad promoting an RPS.

The best feature of the Power of Wind is certainly the Current Issues section that explains wind power policies in plain English. I hope that Current Issues stays updated; it amazes me how many times I try to find new information on energy legislation, only to go advocacy groups’ online newsrooms or press releases and find that the most recent updates are from 2004.

The site is still young, but my recommendation would be to add state-level news about wind power. There is so much action happening around the country; it would be great to have one-stop shop for all your wind power news needs.

Overall, the site is much easier to read and navigate that AWEA’s main website, which is rather overwhelming, even for me. The Power of Wind promises to be an accessible, informational place for wind advocates and those wanting to learn more about it.

Study Says U.S. Top in Small Wind Sales

Photo credit: NREL

A new study by the American Wind Energy Association (AWEA) found that U.S. manufacturers dominate the world’s market share of small wind turbine sales. Comparatively, global sales of larger, utility-scale turbines are led by companies like Denmark’s Vestas, Spain’s Gamesa and India’s Suzlon, who are also hungrily eying the U.S. market.

The 2007 Small Wind Turbine Global Market Study reports that about half of U.S. manufacturers’ sales are made overseas, and the other half satisfies about 98 percent of the small wind demand here at home. Small wind systems are defined as those with 100 kilowatts (kW) of capacity or less, and in 2006 nearly 7,000 Americans purchased them for their homes, farms, or businesses.

The key to building up the market for small wind, according to AWEA and other wind power advocates, is to provide stable federal tax credits and incentives. Ron Stimmel, AWEA’s small-wind advocate, pointed out that “small wind is the only renewable energy technology without a federal-level tax credit.” At $10,000 - $55,000 each, small wind turbines aren’t cheap.

It’s good news that, for once, the U.S. is leading the way in something small, clean, and local. Whether it’s for a community school, a farm, or a home, small wind allows people to reduce their reliance on dirty energy and create their own clean source. American wind power of any size, however, suffers from unreliable federal policies, like the production tax credit (PTC) for large wind that has to be renewed every few years. Wind farm construction increases quickly when the PTC is renewed and dies off as it nears expiration. This boom-and-bust cycle is bad for the wind power economy and our energy system. We need consistent incentives for a versitile energy source that can power a utility or a farm down the road.

Buy Renewable Energy for Yourself

Today the U.S. House is likely to vote on the Udall-Platts Amendment to the energy bill. This legislation would require 15 percent of our nation’s electricity to come from renewable sources by the year 2020. It’s high time the federal government catch up to so many states that already have implemented 21st century policies like this one.

But in addition to broad state and federal programs, consumers can also do some renewable energy good for themselves, even if they don’t own a wind turbine or live in a sunny area. They can buy green power.

“Green power” is a term for clean, renewable energy. More than 600 utilities in 36 states give their customers the option to buy their power from renewable energy sources (depending on the state, they normally include solar power, wind, biomass, hydropower, or geothermal) rather than traditional ones (likely to be coal). Although the transmission system can’t guarantee that particular energy from a wind farm makes it to your refrigerator, the total amount of green electricity that travels over the entire system is increased because (ideally) the utility is taking all of the extra revenue and investing in more renewable energy sources.

My fellow blogger Philip Proefrock just covered a green power program he is considering in his homestate of Michigan. Green power programs do vary, whether it’s the location from which the renewable energy is coming (in state or out of state) or the source (I know of one municipal provider that promotes destructive Canadian hydropower as an eco-friendly option, so make sure you know where the energy is coming from).

Here in Minnesota, I purchase wind power through Xcel Energy’s Windsource program. The initial cost is a little more than $3.50 per 100 kWh block, but I also get a credit on my bill for the avoided fuel costs of conventional (i.e. coal) power. The credit varies each month, but my cost last month was less than $11. Windsource was also audited by the Green-e program to ensure that ratepayers’ money is going to build new renewable energy sources, and it passed with flying colors: Windsource funds the costs associated with Xcel purchasing wind power from private owners of wind turbines and new wind generation facilities across the state, so I feel good about my investment.

Find out whether you can buy green power in your state at the U.S. Department of Energy. If you can’t buy green power locally, consider investing in renewable energy credits (RECs) to offset your emissions.

U.S. House Vote on Renewable Energy Requirements “Likely”

According to the American Wind Energy Association, U.S. House of Representatives Speaker Nancy Pelosi (D-CA) recently told wind power supporters that a House vote on a national renewable portfolio standard (RPS) was likely to happen the week of July 30.

A renewable portfolio standard – also called a renewable energy standard – is a measure requiring utilities to get a certain amount of their power from renewable sources by a particular time.

Last month in the Senate, Senator Jeff Bingaman’s (D-NM) RPS amendment to the energy bill was killed before a vote could be held. Although the current House version of the energy bill does not have an RPS provision, Representatives Tom Udall (D-NM) and Todd Platts (R-PA) are expected to offer an amendment requiring utilities to get 20 percent of their energy from renewables by 2020. This amendment is based on H.R. 969, which calls for an RPS and is also authored by Udall and Platts. (Make sure your Representative is one of the 120 co-sponsors here).

In her meeting with wind power supporters, Pelosi underscored the critical role an RPS would play in moving the nation towards global warming solutions.

According to the Union of Concerned Scientists, a 20 percent by 2020 RPS would save consumers nearly $11 billion on energy bills by 2030 and save nearly 2 billion short tons of coal from being burned up into the atmosphere. Similarly, the American Solar Energy Society found that an RPS could help create nearly 40 million new jobs in the U.S. by 2030 in the renewable energy and energy efficiency sectors.

Wind Turbine Manufacturer Gamesa Agrees to its First U.S. Union Contract

Gamesa, a Spanish wind turbine manufacturer, has hammered out its first-ever U.S. union contract with the United Steelworkers (USW). Workers at two Gamesa facilities in Pennsylvania voted to approve their first contract with 80 percent in favor of it. The agreement lays the foundation for a stronger partnership between one of the world’s largest wind turbine manufacturers – and the only one that makes its blades, nacelles, and towers all in the U.S. – and the 850,000 member union.

The three-year contract raises worker salaries by more than 10 percent, as well as provides for bonuses and benefits for roughly 600 employees. Michael Peck, a Gamesa spokesman, called the contract “a world-class agreement." Tom Conway, USW international vice president, agreed:

“Our union is proud to partner with Gamesa to further grow their domestic manufacturing base and promote wind energy as a source of clean, renewable energy and good jobs.”

Gamesa and other wind power companies have been lured to Pennsylvania by a host of tax incentives and the adoption of a Renewable Energy Standard that doubled the state's renewable energy use to 20 percent. PA is one of the top green power purchasers in the nation according to the Environmental Protection Agency.

The United Steelworkers have been longtime supporters of wind power; they and the Sierra Club founded the Blue Green Alliance that advocates for a cleaner environment and good jobs. USW also co-founded the Apollo Alliance, a coalition of labor, business, and environmental organizations supporting clean energy and a strong economy.

House Bill Threatens Wind Power

Last week, the U.S. House of Representatives’ Natural Resources Committee held a hearing on H.R. 2337, The Energy Policy Reform and Revitalization Act. The bill, according to the nonprofit Alliance to Save Energy, promotes alternative energy and efficiency, including a green building program that would require all major new facility construction projects funded in whole or in part through the Department of the Interior, National Ocean Service, National Marine Fisheries Service, or the Forest Service to meet or exceed silver level LEED standards.

But a provision in the bill has other clean energy supporters up in arms.

Subtitle D, called the Global Warming Wildlife Survival Act, would require new hoops and hurdles for wind power production. The American Wind Energy Association says the law would “effectively shut down the wind energy production industry in the United States,” and House members of both political parties questioned why the wind industry should face new requirements that have never applied to other energy sectors. Some of those requirements include:

  • Directing the U.S. Fish & Wildlife Service (USFWS) to review every existing and planned wind project and penalize operation of wind energy facilities not formally certified by USFWS.
  • Landowners and farmers with wind turbines on their property would be subject to inspection requirements at any time.
  • Landowners and farmers could face one year in jail or a $50,000 penalty for constructing or operating an uncertified wind turbine, regardless of whether it is for personal or commercial use.

In response to the Global Warming Wildlife Surivial Act, the wind industry points out that it is working with wildlife advocates, government officials, and scientists on a Wind Turbine Guidelines Advisory Committee to examine a national strategy for siting turbines. These stakeholders should decide how best to protect wildlife and support the growth of clean wind power, AWEA says, not Washington bureaucrats.

A report released by the National Academy of Sciences earlier this month concluded that wind turbines cause about .003 percent of human-caused bird mortality. That’s about one thousand times lower than bird deaths from house cats. Previous studies have come to similar conclusions. The report also points out that the locations of wind farms must be sited carefully to minimize the negative impacts on birds and that each wind project should be considered on its own merits. The Audubon Society’s Director of Conservation Policy, Mike Daulton, testified before Congress on May 1 that turbine siting must be done cautiously to minimize the impact on wildlife, but did not discount wind power entirely:

“As the threats of global warming loom ever larger, alternative energy sources like wind power are essential. Many new wind power projects will need to be constructed across the country as part of any serious nationwide effort to address global warming…Audubon strongly supports wind power as a clean alternative energy source that reduces the threat of global warming. Each individual wind project, however, has a unique set of circumstances and should be evaluated on its own merits.”

Committee Chairman Nick Rahall (D-WV) introduced H.R. 2337. West Virginia is the second largest supplier of our nation’s coal.

Further action is scheduled for June.

Yet Another Wind Power Design

A seemingly simple alteration a wind turbine blade’s traditional shape could result in huge improvements in efficiency.

WhalePower Corporation out of Toronto, Canada has designed a turbine blade with rounded, teeth-like bumps along the leading edge. The company’s name is a nod to the humpback whale, whose flipper was the inspiration for the design.

The agility of the humpback whale is astonishing, given that they can be over 50 feet long, weigh nearly 80,000 pounds, yet move quickly and tightly in the water. One of the animal's advantages, according to scientists, is the unique row of bumps or “tubercles” along the leading edge of their flippers that dramatically increase the whale’s aerodynamic efficiency. Specifically, researchers found a 32 percent lower drag and 8 percent improvement in lift from a flipper with a serrated edge compared to a smooth one.

Businessman Stephen Dewar heard about the humpback research and contacted one of the scientists involved, Professor Frank Fish of West Chester University in Pennsylvania. After a few meetings, they enlisted the help of some local engineers and formed WhalePower, taking a cue from Mother Nature and modeling their blade design after the whale’s flipper.

WhalePower claims that their turbine design can capture more wind energy at much lower speeds than traditional designs. The channels created by the teeth at the blade's edge cause separate wind streams to accelerate across the surface of the blade in rotating flows. These “energy-packed” vortexes increase the lift force on the blade. For example, Dewar told the Toronto Star that this design produces the same power at 11 miles per hour that one would expect at 18 miles per hour. Furthermore, he claimed these channels prevent airflow from moving along the span of the blade and past the tip, which can create noise, instability and a loss of energy. By keeping the air flow nicely channeled, more wind is captured and noise is reduced.

Dewar sees this “biomimicry” design – the fusion of biology and engineering – reaching beyond wind power.

“’This changes the game,’ says Dewar, adding that any system using a fan or turbine could also benefit from the new design. This includes everything from better turbines for hydroelectric generation to residential ceiling fans that use less electricity. ‘If we've got what we think we've got, then the range of applications is staggering.’”

The Ontario Centres of Excellence and the Ontario Power Authority have contributed over $60,000 USD for early research and to encourage collaboration with a wind engineering group at the University of Western Ontario. The next and arguably most crucial step to commercial production is independent, third party verification of the blade’s performance.

Ogden, Utah Getting Greener

Ogden, Utah has joined the growing number of American cities buying clean, renewable energy to power their community. Mayor Matthew Godfrey announced that Ogden will buy enough renewable energy through Rocky Mountain Power’s Blue Sky program to cover about 19 percent of city buildings’ electricity use.

The Mayor also urged residents and businesses to participate in the Blue Sky program, which gets its electricity from six wind power facilities and is one of the most popular green power programs in the nation. Mayor Godfrey’s Blue Sky Community Challenge aims to get 5 percent of businesses and households signed up for renewable energy by the end of October.

Increasing investment in renewable energy is an important economic move for Ogden, a city of about 78,000 people. It has been attracting several outdoor recreation companies, and Mayor Godfrey explained that having clean air is “critical” to attracting these businesses.

The Sustainable Ogden Committee developed the challenge, and has other initiatives in the works. A Fresh Air Friday program will encourage the use of public transportation, converting city vehicle fleets to renewable fuels, and a downtown bicycle program.

Ogden’s purchase of wind power will cut carbon dioxide (CO2) emissions – a main contributor to global warming – by 900 tons each year. That’s equivalent to planting about 354 acres of trees, according to a statement from the Mayor. If Ogden residents meet the Blue Sky Community Challenge, it would cut CO2 emissions by about 5,900 tons each year. A typical household could get 100 percent of its energy from renewable power for an extra $11.70 per month.
