New York City goes green by launching a 100% wind and solar powered billboard this Holiday Season.

As alternative energy continues to be the hot topic in our flailing economy, New York City sets an environmental example by launching Times Square’s first 100 percent eco-powered billboard.

The billboard powered entirely by wind and sun, is the first such sign in New York City. It will be erected by Ricoh Company, Ltd., a Japanese company that strives to be outstanding in all areas of the environment, society, and the economy. Their first eco-signage project dates back to April 2003 in Osaka, Japan.

Powered By Wind Turbines and Solar Panels

The electricity for the billboard will be produced entirely by solar and wind power and stored in 16 batteries. No electricity will be purchased from local power companies.

Sixteen wind turbines and 65 solar panels will produce an average of 98 kwh of electricity per day (93 kwh from wind power and 5kwh from solar). To put the savings into perspective: the same amount of electricity required by an ordinary sign would result in as much as 18 tons of carbon dioxide per year. The batteries can hold four days worth of supply. However if there is insufficient wind or solar power, the sign may not light up, an eventuality that Ricoh readily accepts.

Mariah Power of Reno, Nevada has developed a new efficient and attractive wind harvesting station called the Windspire that has a quite attractive profile for suburban dwellers. The Windspire, at 30 feet tall and 2 feet wide, takes advantage of the access of vertical space you have out on your suburban lot. With only a ½ acre of land or more, the Windspire will work effectively. The 1 kW inverter will produce about 1900 kW hours each year in 12 mile per hour average winds. The Windspire even includes an internal wireless modem that will continuously communicate with your computer about the amount of power is generated in your backyard while at work, sleeping, eating, and generally going about your day. This allows you to track and check the generation progress at any time.

The propeller construction is different from more common wind turbine. The vertical construction allows propellers to turn at the same speed as the wind. This allows it to be virtually silent and safe for both birds and people. In addition to the safety and tranquility, at only 30 feet in height, it is below most residential and urban zoning restrictions. And at a tall height in the sky, it is responsibly easy on the eye. The design is sleek, light, and simple. Available in customizable colors and designs, you can even appropriate the construction for your own aesthetic tastes.

With simple and complete installation, the kit is an easy addition to the home. Priced at only $3,995, the lowest cost of anything of its kind, wind power immediately becomes an affordable commodity. In addition to providing the product, Windspire’s site has a useful tool for clients and potential clients. The tool helps you evaluate your site and appropriate the installation to be the most effective.

So, if you have been looking for a way to incorporate alternative energy in your home but always thought your site wasn’t appropriate, think again. With sleekness and silence, your neighbors will only be intrigued.

As alternative energy is coming of age, new designs and more inventions are making it easy for you to install alternative energy generations stations at your home. A West Australian designer is working on a turbine system invention small enough to be installed on your roof. At a meter in length and a half meter in height, this invention is even easier to apply to your household energy consumption (and production). Keep your eyes open, pretty soon we will be able to put a turbine on our car, belt, and bike to generate usable amounts of energy.

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.

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.

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.

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.

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.

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.

The first was HB 1281, which expands the state’s renewable energy standard by doubling the goal to 20 percent of all resources by 2020 for big utilities. It also includes a goal of 10 percent renewables by 2020 for small utilities and caps the implementation cost for customers of the big utilities to 2 percent of their monthly electric bill. Rural electric associations have a 3-to-1 credit to invest in solar energy.

The next bill, SB 100, makes it easier to build or expand transmission lines to move wind power from the rural areas where it’s generated to the populated urban areas where it’s needed. Utilities can recover the construction costs from customers before the power line is operational.

Governor Ritter explained the bills’ significance:

"These new laws will improve our economic security, our environmental security and our national security. They will breathe new economic life into rural Colorado. They will create new jobs, and they will say to the rest of the world, 'Colorado is open for business in what will be one of the most important industries of the 21st century.'"

According to the Denver Business Journal, the bills had the support of lawmakers, energy providers, and renewable energy advocates.

But there are still misunderstandings and legitimate opportunities surrounding wind power, so here are some issues swirling around the world’s fastest growing energy source.

Cost: The cost of wind power continues to plummet, and it’s now on par with traditional energy sources. In fact, there are several cases where customers who originally paid a premium for wind power on their electric bill ended up with lower bills than their neighbors who relied solely on fuels like natural gas. While the cost of natural gas is volatile, the fuel for wind power is always free.

Wildlife: Modern wind turbines are not massacring birds. The Audubon Society endorses wind power, and a study by Western EcoSystems Technology found that cats kill more birds annually than wind turbines. The problems of the Altamont Pass wind farm in California – which was constructed in the 1980s on a migratory path for raptors – are often cited as proof that turbines in general are dangerous for birds. But with more modern siting techniques and technology (such as blades that revolve more slowly so birds can spot them), there is rarely a problem with bird deaths.

Storage and reliability: A commercialized technology that allows for wind power storage would be a revolutionary advancement (there are companies working on it). But I’m not worried about shivering in the dark because we’re not moving to 100 percent wind power tomorrow. The U.S. is not even close to the point at which storage should hold us back from wind. Instead, we should be working towards getting as much wind onto the grid as it can reasonably handle as fast as possible. Nationally, we get less than 1 percent of our electricity from wind, while some European countries are getting 20 percent from it and without any storage. According to the American Wind Energy Association, a flexible, diverse energy system that includes natural gas and renewables like hydropower can provide the “storage” or backup reliability. In fact, Xcel Energy, one of the largest utilities in the nation, has proposed more wind and hydropower to accommodate the growing need for baseload generation. A spokeswoman from Xcel explained, “[The] package was the best way – from an environmental, economic and reliability standpoint – to meet the remaining future needs of our electricity customers in the Upper Midwest.”

Furthermore, a study prepared for the Minnesota Public Utilities Commission found that wind power can reliably contribute up to 25 percent of the Midwest’s electricity with minimal cost if supported with good regulatory policies and modern transmission lines.

Wind power is here to stay, and as even more companies and individuals take advantage of it, the rest of the country will feel the impact: Stronger rural economies, less dependence on fossil fuels, cleaner air and water, and cuts to our global warming pollution.
