Wind turbine definitions

A bit of searching for established definitions of turbine categories left me with the impression that the reader and installer of a machine essentially defines the "middle wind" (community wind) turbine size. Here's what I think
  • micro- or architectural wind turbine: has a rated power of under 500 watts
  • small wind turbine: has a rated power of 500 watts to 35 kW
  • community wind: has a rated power of 35 kW to 250 kW (or as North Dakota SEED indirectly states, "all developments that do qualify for net metering")
  • large wind turbine: has a rated power of more than 250 kW.
The rated power of a "community wind turbine" is defined by the respective state's legislators, but the above range is workable for USDA Rural Development Energy Program projects. In the 2002 "Farm Bill," Section 9006 was for Renewable Energy Systems and Energy Efficiency. Nearly every person living on the Great and Upper Plains can compete for energy development in the 2007 "Farm Bill."

Farm, Nutrition, and Bioenergy Act of 2007 is passed

It is the sense of Congress in HR 2419 RH that—
(1) energy demand in the United States is projected to increase by more than 30 percent over the next two decades;
(2) increased production of renewable energy and growth of its infrastructure would assist the United States in meeting the growing energy demand;
(3) continued, and even accelerated, development of renewable energy inputs and technologies provide numerous benefits to the United States, including improved national security and economic growth;
(4) while it should be a priority of the Federal Government to continue to promote policies and in1centives to stimulate growth and development of renewable energy infrastructure, it should be recognized that the marketplace is also an important instrument to determine which renewable energy sources and technologies will provide the most efficient and effective energy production;
(5) renewable energy inputs and technology must be available in abundant quantities and provide energy at competitive prices in a reliable manner for the American consumer; and
(6) it is in the interest of the United States to diversify its energy portfolio and increase the energy independence of the United States by further developing alternative forms of energy.

In that context, then, important areas to explore include
Title VI—Rural Development
Sec. 6013. Rural entrepreneur and microenterprise assistance program.
Sec. 6021. Rural strategic investment program.
Sec. 6030. Guarantees for bonds and notes issued for electrification or telephone purposes.

Title IX—Energy
Sec. 9004. Energy audit and renewable energy development program.Sec. 9005. Renewable energy systems and energy efficiency improvements.
Sec. 9009. Energy Council of the Department of Agriculture.
Sec. 9011. Rural energy self-sufficiency initiative.

Nuclear power is government- and security-intensive. Wind and solar power and biodiesel production for local use are agricultural land-intensive. The latter empower rural Americans to develop the "Energy Basket" as they provided for the world's "Bread Basket." We have to act, not just plan.

Farm energy production is blossoming

A business opportunity in farm energy production is something I can't pass by. I will move most of my time from blogging to developing a business plan; even so, I will post twice each week- fully remembering what my Grandma Moen used to warn: "The road to hell is paved with good intentions!"- to spur wind development and its subsequent rural development.

As you know, farm energy production is harnessing renewable energy sources such as wind, oil seeds, solar, biomass, geothermal, and microhydro to reduce energy consumption and sell excess energy in the forms of electricity and biofuels.

Farm energy production is fostered by federal legislation and regulated by the U.S. Department of Agriculture and other agencies such as IRS.

Here in South Dakota, which has the nation's fourth-best annual wind power potential of 1,030 billion kWh and marginal to good agricultural land, farm energy production is a superb fit into daily agricultural practices.

In late May, former Senators Bob Dole (R-KS) and Tom Daschle (D-SD) released New Markets for American Agriculture, a report by the 21st Century Agriculture Project, sponsored by the Bipartisan Policy Center. The report highlights investing in biofuels and wind farms to provide farmers and ranchers with new and diversified sources of income.

"Today, America's farmers and ranchers are facing an array of new challenges. ... Amidst these many challenges, lay many opportunities...."

"A strong agricultural sector is a pillar of America’s growing economy,
• providing a secure domestic food supply
• helping to reduce our dependence on foreign oil
• generating renewable energy
• increasing exports and
• providing needed income to rural communities."

"Representatives Stephanie Herseth Sandlin (D-SD), Jeff Fortenberry (R-NE) and Marcy Kaptur (D-OH) introduced major new clean energy development legislation for the next Farm Bill. Their bipartisan bill expands the size and scope of the already-successful Farm Bill Section 9006 clean energy program into a new "Rural Energy for America Program," or REAP. HR 2154 IH cited as the 'Rural Energy for America Act of 2007.'" Source.

Information research, analysis, and writing are put to work developing visible knowledge for farm energy.

In the same vein of making knowledge visible, "roadmaps" can be developed and marketed to
• streamline application
• reduce paperwork
• ensure feasibility and achievability and
• clarify who is as well as what technologies are eligible for different programs.

Visible knowledge informs and guides potential participants to ensure compliance and strengthen the likelihood of successful outcomes. Ag business and rural small business people have severe time constraints and may not have ready access to the broad scope of information and expertise they need to take part in farm energy projects. Visible knowledge tackles those two problems.

Buffer Zone for Wind Turbines, "Extreme" Enzymes, and more good wind

Cape Wind Flies in Under the Radar

Hyannis, Massachusetts; [RenewableEnergyAccess.com]; June 21, 2007

The most recent Department of Defense (DOD) report analyzing the effects of offshore wind turbines on early warning radar missile defense systems is good news for Massachusetts' highly publicized Cape Wind project, which is scheduled to come online in 2010.

Issued by the Missile Defense Agency, the nine-page report recommends a 25-kilometer (km) wind turbine offset or buffer zone be established to "mitigate impact" on the PAVE PAWS early warning radar system at the Cape Cod Air Force Station (AFS).

The Cape Wind project in Nantucket Sound, with its 130 GE 3.6-megawatt XL wind turbines in Nantucket Sound, falls just outside this zone. In addition, the analysis shows the wind turbines in Hull, Massachusetts, are also beyond the recommended buffer.

The analysis by the DOD, however, is the third such report to be issued in recent years that has found the Cape Wind project would not negatively impact or be a concern to the PAVE PAWS radar system.

For wind turbines that lie within the 25 km offset zone, the report notes that further study would be required to assess the impact accounting for location within the radar's field of view and the relative height of the wind turbine and the radar's main beam.

Biomass & Nature's "Extreme" Enzymes

Sandia National Laboratory researchers looking to biology in earth's extreme environments
to help solve lignocellulosic ethanol puzzle

Livermore, California [RenewableEnergyAccess.com] June 15, 2007

Buried beneath a sulfurous cauldron in European seas lies a class of microorganisms known as "extremophiles," so named because of the extreme environmental conditions in which they live and thrive.

Almost as radical, perhaps, is the idea that these organisms and their associated enzymes could somehow unlock the key to a new transportation economy based on a renewable biofuel, lignocellulosic {Fibrous/woody plant (like mesquite) based} ethanol.

However the primary hurdle preventing lignocellulosic ethanol ... its efficient and cost-effective processing. "Extremophiles'" enzymes may get over that hurdle.

Blake Simmons, a chemical engineer and project lead at Sandia's Livermore, California, site, says More than a billion tons of biomass is estimated to be created each year in the timber and agricultural industries, as well as a variety of grasses and potential energy crops."

"Though we're probably decades away from that...." "Because lignocellulosic biomass is such a multifaceted material, we need to have a fundamental understanding of how it works ." {Plant cellulose is strong and highly resistant to rotting and decay. One commenter on the original report pointed out "While there may be millions of tons of lignocellulosic biomass on U.S. soil, collecting and moving it to processing plants may use more energy than is available from lignocellulosic ethanol." Available energy remains a hotly contested quality of ethanol, too.}

Senate Passes Thune Wind Energy Amendment

Washington, DC [RenewableEnergyAccess.com] June 21, 2007

The United States Senate passed U.S. Senator John Thune's energy transmission amendment to the energy bill, which would promote the development of energy transmission infrastructure, on June 19.

"This legislation is critical to promoting the development of wind energy in South Dakota and around the country. As the windiest state in the nation, {whoa, there, Senator! We are ranked fourth-best, according to the American Wind Energy Assoc.} South Dakota will greatly benefit from these provisions {as will the other 19 windy states on AWEA's Wind Energy: An Untapped Resource}.

Thune's amendment, #1609, would promote the creation of energy corridors that would facilitate the transference of wind energy generated in South Dakota to high-demand areas.

"We have the wind energy in South Dakota that the major power consumers in our nation need. The missing link is transmission infrastructure to deliver this power," Thune said.

Yesterday, the Senate Finance Committee voted in favor of energy tax credits, including the Production Tax Credit advanced by Senator Thune, which creates incentives for the development of wind energy. "Today's victories should be celebrated by everyone who wants to promote wind energy in South Dakota," Thune said.

The following guide will have information SDans can put to work in their farm and business energy projects as well as their home energy efficiency efforts.

Wind power is one piece of a farm's energy business

It has been proposed in the 2007 "Farm Bill" that the Secretary of USDA make competitive grants to eligible entities to provide rebates for

• farmers

• ranchers

• rural school districts and

• rural small businesses

to purchase renewable energy systems and make energy efficiency improvements. The final draft may include agricultural operations in non-rural areas (such as greenhouses) and schools.


for a range of modern renewable energy technologies like

• biofuels (which includes cellulosic ethanol)

• wind

• solar

• biomass

• biogas and

• energy efficiency.

Amidst these many challenges, lay many opportunities for determining the type of energy production that best fits your operation or situation (such as a community, school, or business).

As Congress produces the final draft of the 2007 "Farm Bill," it may eliminate the direct payment program and redirect funds into this program ... promoting new income-generating opportunities for farmers {and others} in markets such as biofuels, renewable electricity, carbon sequestration, and conservation.
____________________________

A Piece of Work, Part I

You know when something is going to be lengthy or "soapboxish" when Roman numerals are used in a title. With that warning, off we go.

A recent wave of large wind turbine orders and project announcements spanning four states suggests that wind power will continue growing strong at least through 2007. That domestic demand for large wind turbines (LWTs) has created a two- to three-year backlog at the manufacturers of LWTs as new wind farms also sprout up throughout America.

Coteau Wind & Power is being developed to meet a dometstic demand for a large wind turbine it the 750 - 900 kW range that is expected to continue and actually accelerate. Price increases of crude oil, natural gas, and coal, and the spectre of nuclear power plants make wind a very appealing alternative power source for electricity generation.

In a 1999 study conducted by the World Energy Council (WEC) projected worldwide wind capacity of 13 gigawatts (GW) by 2000 (actual installed capacity was 13.6 GW by the end of 1999), increasing to 72 GW by 2010 and 180 GW by 2020.

• (1 gigawatt = 1,000 megawatts = 1,000,000 kilowatts; if you're paying 7 cents per kWh, 1 GWh = $70,000,000. "There's money in them thar breezes!")

Coteau Wind & Power will use these numbers as goals in order to be "in the right place at the right time" to profit from the surge in growth in wind turbine installations with a goal of manufacturing and delivering 4,040 turbines by 2020 in the Great and Upper Great Plains.

A faster pace of wind development comes at a crucial time for electricity producers; crude oil peaked at $78.00 per barrel in mid- July, 2006, as did the price of natural gas (NG) ( in dollars per million cubic feet). A main derivative of NG, agricultural nitrogen,
also shot up in price.

By June 2007, the price of crude oil had declined to $68.00 per barrel and Big Oil company executives commented that with the increased production of biofuels, there is much less urgency to expand crude oil refining capacity.

{Americans should expect higher food costs as more food grains are converted into ethanol rather than put in grocery stores as well as higher gasoline and other petrochemical product prices because of "less urgency to expand capacity."}

Even the highest-use fossil fuel for generating electricity- coal- indirectly became more expensive due to pollution-reduction equipment regulations, special-interest groups' objections, and train coal-car derailments.

Nor is hydro-electric power immune from price increases. For decades "hydro" has been a mainstay for rural electricifcation, providing thousands of megawatthours of inexpensive power from major U.S. rivers like the Missouri in the Upper Great Plains.

Extended drought or near-drought conditions in the watersheds of their rivers, compounded by higher average water consumption for water parks, lawns, U.S. Open greens watering, wild-fire fighting, and agricultural irrigation, will result in record-low water levels and subsequent decreased electricity production by water turbines in the rivers' dams. When supply decreases, spot-market electricity purchases lead to consumer rate increases.

Coteau Wind & Power will manufacture wind turbines that efficiently harvest electricity from wind power, a renewable resource that will never "dry up," can't be doled out by foreign governments, and doesn't poison the evironment with mercury, cadmium, and sulfuric acid.

Unlike the traditional fuels of electricity-generating plants, wind turbines are not constrained by

• global geopolitics
• an inability to safely dispose of nuclear or petroleum wastes
• heightened concerns about environmental damage
• almost complete concentration of generation capability in single sites
• labor and transportation disruptions
• increasingly limited water supplies and
• increasing "Not In My Back Yard" resistance stemming from concerns regarding

• land consumption
• aesthetics
• air, noise, traffic pollution and
• materials and time costs

in the construction of new traditional power plants.
