Wind turbines are one of the most promising sources of large-scale renewable power.  Wind power doesn’t produce any pollutants, and unlike water or fuel resources, wind is literally an endless source of energy.  However, wind farms do require a substantial amount of space, which is why a much more efficient design like the “Wind Lens” could make wind energy cheaper and more practical.

Developed by researchers at Kyushu University’s Research Institute for Applied Mechanics (RIAM), the wind lens design utilizes a curved housing that encircles the blades of a wind turbine.  The ring is comprised of an inlet shroud, diffuser, and brim that work together to create a low-pressure pocket behind the turbine when wind passes around the ring.  The resulting suction can triple the effective wind speed that drives the turbine blades.

Increasing the energy generated from a single turbine has the potential to make wind power even cheaper than nuclear energy, and wind turbines carry none of the risks associated with nuclear power plants.  Their primary drawbacks are interference with wildlife (such as migrating flocks of birds) and noise; fortunately, the Wind Lens design makes turbines quieter as well as more efficient.

But could wind turbines really make a substantial contribution to US energy demand?  Absolutely.  A recent MNN article by Karl Burkart breaks down the numbers in more detail, but the bottom line is this:  if improved turbines like the Wind Lens were installed in just 20% of America’s “high wind potential” areas, they could provide all the power consumed in the US.

Prototypes are already being tested at Kyushu University.  And the developers are already thinking ahead to the possibilities for large-scale implementation, including floating offshore wind farms far out to sea that could take advantage of uninterrupted air currents without competing for space on land.

ral Development Dallas Tonsager made the announcement on behalf of the Secretary while attending the Pennsylvania meeting of the National Rural Electric Association (NRECA).

“The Obama Administration is committed to making America more energy efficient, and in doing so, more competitive by encouraging rural businesses build renewable energy systems,” said Tonsager.

The projects announced today will provide rural small businesses and agricultural producers the opportunity to conduct feasibility studies for renewable energy system installations. Eligible intermediaries, such as universities, will receive funds to conduct energy audits which will lead to energy savings and initiatives that will reduce energy consumption for years to come.

Tonsager said that Pennsylvania State University has been selected to receive a $99,676 grant to conduct a statewide initiative that offers technical assistance and workforce solutions through energy audits. Saint Francis University, also in Pennsylvania, was selected to receive $100,000 to help agricultural producers and rural small businesses reduce energy consumption and cost through technical assistance provided by the university.

In Charleston, W. Va., the West Virginia Division of Energy has been selected to receive a $100,000 grant to complete 130 energy audits for rural small businesses to help them reduce energy usage and operating costs. Boise State University in Idaho was selected to receive a $100,000 grant to offer energy savings- information and energy audits to more than 1,500 manufacturing-related agricultural producers and small business in the state.

Arbre Farms Corporation in Walkerville, Mich., was selected to receive $7,000 to evaluate the feasibility of installing and operating an anaerobic digester that could produce and use biogas as a substitute for propane to power the farm’s boilers. “Last year, these same feasibility study funds provided through REAP assisted in a tremendous year of anaerobic digester development and are an important first step in a successful renewable energy project,” said Tonsager. “Construction is beginning on four USDA funded digester projects here in Pennsylvania and six digester projects next door in Ohio. These systems will provide additional farm income, contribute to better nutrient management, and produce clean, renewable electricity for thousands of homes in the community.”

Today’s announcement is in concert with an agreement signed by Secretary Vilsack in December, 2009. During climate change talks in Copenhagen, Denmark, the Secretary signed a historic agreement to help U.S. dairy producers cut greenhouse gas emissions. The agreement between USDA and the Innovation Center for U.S. Dairy calls for the parties to work to reduce greenhouse gas emissions from dairy farms by 25 percent by 2020.

With today’s announcement, USDA is awarding more than $2.4 million in energy audits grants, Renewable Energy Development Assistance Grants; and more than $1.2 million to support feasibility study projects.

Funding is made available through the Rural Energy for America Program (REAP) under the 2008 Farm Bill. REAP loan guarantees and grants can be used for renewable energy systems, energy efficiency improvements, feasibility studies, renewable energy development assistance and energy audits. More information on the REAP program can be found at http://www.rurdev.usda.gov/BCP_ReapGrants.html Funding of each recipient is contingent upon the recipient meeting the conditions for the grant. The following is a complete list of award recipients announced today.

Since taking office, the Obama administration has taken historic steps to improve the lives of rural Americans, put people back to work and build thriving economies in rural communities. From proposing the American Jobs Act to establishing the first-ever White House Rural Council – chaired by Agriculture Secretary Tom Vilsack – the President wants the federal government to be the best possible partner for rural businesses and entrepreneurs creating job opportunities and for people who want to live, work, and raise their families in rural communities.

USDA, through its Rural Development mission area, administers and manages housing, business and community infrastructure and facility programs through a national network of state and local offices. Rural Development has an active portfolio of more than $155 billion in affordable loans and loan guarantees. These programs are designed to improve the economic stability of rural communities, businesses, residents, farmers and ranchers and improve the quality of life in rural America.

The transmission lines include the Zephyr line, the TransWest Express and the Overland transmission project. Rocky Mountain Power’s Gateway West is another major new line that would move wind energy westward.

The fifth proposed pumped storage project would be located in Converse County, near the planned origination point of the High Plains Express, which is intended to help deliver renewable energy through Wyoming, Colorado and New Mexico to Arizona.

The pumped storage projects range in size from 300 MW to 500 MW; the combined capacity of the projects, if all were developed, would be 1,900 MW. Energy storage potential would be more than 50 GWh – equivalent to what 3,000 MW of wind turbines would put out for 17 hours at their maximum.

Gridflex is pursuing partnerships with a number of wind and transmission developers.

Some people see wind turbines as eyesores or complain about the sound of their whirring blades, but Soren Hermansen, chief proselytizer for the islands renewable energy experiment and director of the Samso Energy Academy, disagrees. “If you own a share in a wind turbine it looks better, it sounds better,” he says. “It sounds like money in the bank.”  Ed. Note – Personally, the 60Hz Hummmmm of the powerlines that I don’t live near are annoying too.

Have to look into vertical turbines for our area.  We’ll have calm winds for weeks on end, then we’ll have gusts up to 50+ miles per hour.  This can wreak havoc on many wind systems.  Good to see options for urban dwellers and businesses that work, too.

“… Solar panels and wind turbines offer the promise of clean electricity by deriving their power from wind and the sun. But both suffer from the problem of intermittency: A gust of wind can cause a mill to spin faster, producing a power spike down the line, and a cloud passing over a solar cell can cause a sudden drop in electricity.

Meanwhile, utilities are rushing to upgrade the ability of the region’s interconnected power grid, which is based on 100-year-old technology, to tap renewable resources without causing problems for users. …”
