A new purpose and intent

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.

The report addresses ways to improve economic prospects for agricultural producers with a focus on clean energy development.

Amidst these many challenges, lay many opportunities, for 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.
USDA identified those clean energy types that people in rural America can develop for meeting local and/or national needs
  • anaerobic digestion (Methane Recovery)
  • biogas
  • biofuels production
  • biodiesel
  • solar biomass
  • geothermal
  • solar electric power
  • thermal conversion
  • waste vegetable oil (WVO) for biodiesel production and
  • wind power.
With the price of a barrel of crude oil at $110 or so, these energy types can be put to work generating electricity or replacing some petro-diesel with biodiesel.

WVO disposal is a problem where ever food is made for the public in cafeterias, restaurants, pubs, and the like. Individuals can recycle used cooking oils into biodiesel for small- and medium-sized engines. This can make a difference in getting things done or paying more every year to get those things done. We can act or we can have some cheese with our whine.

The methods, processes, equipment, and experts are on the Web. Perhaps at one time the doing was cheaper than today, but it has never been easier. Energy production is perennial practice that will complement existing ag production.

One example
"Spray-On Solar-Power Cells Are True Breakthrough," Stefan Lovgren, National Geographic News, January 14, 2005.

"Scientists have invented a plastic solar cell that can turn the sun's power into electrical energy, even on a cloudy day."

"The plastic material uses nanotechnology and contains the first solar cells able to harness the sun's invisible, infrared rays. The breakthrough has led theorists to predict that plastic solar cells could one day become five times more efficient than current solar cell technology."

"With further advances, the new plastic "could allow up to 30 percent of the sun's radiant energy to be harnessed, compared to 6 percent in today's best plastic solar cells," said Peter Peumans, a Stanford University electrical engineering professor, who studied the work."

"At a current cost of 25 to 50 cents per kilowatt-hour, solar power is significantly more expensive than conventional electrical power for residences."

About second chances- "Slouching Toward Fargo"

Initially assigned by Rolling Stone magazine to produce a "hatchet job" about Bill Murray and his part-ownership of a minor league baseball team, Slouching Toward Fargo instead was written by Neal Karlen to highlight the fun and good times that should be the heart and soul of baseball.

Even though the St. Paul Saints baseball team was like an "old-time carnival" and consistently sold-out its home, Midway Stadium, offering second chances was the result. Darryl Strawberry, Kevin Gardner, and J.D. Drew were on the roster for a time, as were Ila Borders (first woman pitcher in men's professional baseball), Dave Stevens, and Wayne "Twig" Terwilliger.

Mike Veeck- sounds like wreck- ensured that the fans "got their money's worth" with Tobias, the fresh-baseball delivery pig and inflated sumo-suit wrestling. Veeck, Murray (who attended games when his movie career allowed), athletes, and many other talented front-office people made Midway the best destination of the "Twin Cities" of St. Paul and Minneapolis, Minnesota.

----------------------------------------

In many ways, farm energy production is a second chance the U.S. to regain a bit of energy self-sufficiency. Wind energy in SD carries an estimated 1,030 billion kWhs of power each year; ethanol production and biodiesel production bring better prices for commodities as well as a means to solve a waste-disposal problem by converting used cooking oil into biodiesel. These two forms of energy are abundant in many states and remain "underperforming assets."

Local electricity generation and local biodiesel production for use in transit, fire fighting, mail delivery, and other and services will reduce municipal electricity bills and fuel costs. And the air might smell more like fried chicken than diesel fumes by the end of each day.

But no freshly mown ballpark grass here; today the temperatures are sub-zero and the skies sunny. Standing next to a south-facing wall makes me almost smell that grass; walking back to my car (it's not a St. Paul Saints "Northern League car") instantly snaps me back to "the real world." My footsteps "eek-auk" up to the driver's-side door which groans, as it always does when it is not just cold out there; it's damn cold.

(About now I wish Summer had a second chance.)

USDA hampers Farm energy production

Good afternoon Secretary Conner-

Farm energy production are practices that every ag producer and rural community member can review, then select the best one(s) for their situation.

A natural point to start this review is the Energy Types webpage. The links from the types- such as "anaerobic digester"- go to generic splash pages (in this case, to "Welcome to USDA Rural Development's Electric Programs") that are completely disconnected from the "energy type" link. "

"Muddying the water" seems to be the purpose of the "splash pages;" the producer or resident is left to randomly try "headers" on the chance that something relevant is behind them. Information overload" is increased to the point of leaving the page, angry that promised knowledge on the "energy type" became a "bait and switch" tactic.

More frightening is the thought that the mis-direction was intended, that USDA merely is "running farm energy production up the flagpole" to give the appearance of "being on-board" the national energy security bandwagon.

From the Electric Programs "splash page" is a Renewable Energy link which at first glance, holds promise. More links; perhaps Renewable Energy Technology Resources has something on "anaerobic digesters." Ah, another page of links-

Wind, Solar, Biomass, Geothermal, Hydrogen, Energy Efficiency, and Electric Utility Interconnection. There- Anaerobic Digesters - AgSTAR Program- in Biomass. Excellent! (If you notice the logo and page layout change, you'll see we're now at the EPA. Farm energy production and pollution reduction/management go "hand-in-hand," for this technology, anyhow.)

The AgSTAR Program is a voluntary effort jointly sponsored by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture, and the U.S. Department of Energy. Which means there are three sources of funds for planning and installing your anaerobic digester, three different set of paperwork, and three different sets of regulations and requirements to comply with. (No one said farm energy production was gonna be easy.)

Naturally there's a link list to provide more information on the AgSTAR Program:

Basic Information
Accomplishments
Experts & Industry Directory
Documents Tools and Resources
Workshops/Conferences and
Guide to Operational Systems.

USDA can develop simple link-lists that carry the farmer, rancher, community leader, or lender, from the "energy type" to a specific description (no more than two paragraphs are needed) of what it is and how it can be used in farm energy production.

From there the method (such as "energy efficiency") or technology is briefly described as well. Slash verbiage to provide only information on what is "on the shelf" now; save the research results and vision and mission statements for the land grant colleges.

Following the "what" and "where" is "how;" tell the producer or the town official the steps s/he should expect to take to be a successful farm energy producer. Most of the steps can be made visible for easy understanding and planning; the remaining few can be made known to extension and/or technical professionals for their implementation guidance.

(Lists of these contacts should be highlighted and linked- {don't "nest" links} for easiest way-finding- in the steps.Their knowledge and time are valuable and has to be focused on only those "nuts that are tough to crack.")

"Energy types" link lists need to eliminate "information overload" by delivering the specific information that has been "headlined." Doing that will enable producers and town officials to transform the "bread basket of the world" into America's "energy basket."

Title IX of the 2002 "farm bill" established the precedent-

--new programs and grants for procurement of biobased products
--support development of biorefineries
--educate the public about benefits of biodiesel fuel use
--assist eligible farmers, ranchers, and rural small businesses in purchasing renewable energy systems and
reauthorizes and broadens the bioenergy program.

Site map-like linklists support efficiency in putting the precedent to work in the 2007 "farm bill" Title IX Energy.

Earning $152,878, leasing for $4,000

$152,878 is a conservative estimate of revenue from a large wind turbine on South Dakota ag land. Land owners are being told to accept $4,000 per turbine in a wind lease or their land will be isolated from development.

Sadly, producers have a lot of experience with selling their crops and livestock for poverty-level profits; once again they face marketing a new commodity without knowing its value.

With every hour "superb" wind speed (faster than 24 mph), a 1.5 MW can generate up to 3,195 kW. A South Dakota land owner isn't paid "fair market value" because s/he doesn't yet have "aerinomics" information. S/he has more agronomics information than s/he "can shake a stick at" on other ag practices, but not aerinomics on wind farming.

Utility companies are "cherry picking" some of the nation's fourth-best wind power from land owners from a position of knowing they can

  • sell- at a premium- wind power as "green power" or "blue skies" power and/or
  • sell it as plain ol' power to consumers where rates are 11¢ and even 14¢ kWh.
Larger businesses have, since the dawn of time, "cherry picked" from the low to sell high, so wind farming is just the next "it's only business."

Concentrated solar power station

Molten salt can be used in a solar power generator to store heat for later use is the gist of a The Wall Street Journal report on 2 Jan W 08, p. A7; "Solar Venture Will Draw on Molten Salt," by J. Lynn Lunsford. The report has one process flow diagram.

Some attributes of a concentrated solar energy power system include
  • molten salt stores heat extremely well, losing only about 1% of its heat during a day
  • rising fossil fuel prices have made the system competitive and
  • for generating energy during periods of peak demand when utility companies pay premium prices.
Lee Bailey, Managing director, US Renewables Group-
  • the system functions like a conventional hydropower plant
  • salt is free and inexhaustible and
  • availability is more predictable than water reserves andenvironmental impact is essentially zero.
[If "hydro-like functions" pan out, concentrated solar power stations are potential regulators of wind power. Regulators of wind were identified by the Midwest Independent System Operator organization as a critical development need if wide-spread wind development in South Dakota can be realized.]

The uniqueness of this solar system is in de-coupling the collection of solar energy from producing power, electricity can be generated in periods of inclement weather or even at night using the stored thermal energy in the hot salt tank.

According to Tom Mancini, Sandia National Laboratory; U.S. Department of Energy, the tanks are well-insulated and can store energy for up to a week. Other studies show that the two-tank storage system could have an annual efficiency of about 99 percent.

A concentrated solar power station could be part of a farm energy production system of wind, biogas, and anaerobic digestion.

Everything is connected to every thing else

Your great-uncle (like mine) or great-grandad may have used wind power to pump water from wells. Now a South Dakota resource- 1,030 billion kWhs- is being harnessed to help light homes and businesses.

27 wind turbines are in Highmore, the largest wind farm in South Dakota. Its 27 1.5 MW (1,500 kW) turbines produce enough electricity to power over 14 thousand homes.

Each ton of coal consumed at an electric power plant produces about 2,000 kilowatthours (2 MW) of electricity. 2,000 pounds of coal, 2,000 kWhs; we'll say burning one pound of coal yields one kWh. At these numbers, the turbines at Highmore prevent burning 40.5 tons of coal for every hour of 30+ mph wind.

A 500 megawatt coal plant uses 2.2 billion gallons of water a year, for cooling and for steam production. At these numbers, each turbine at Highmore prevents the loss of 341 gallons of water for every hour of 30+ mph wind. More water for people, plants, and livestock in addition to cleaner air.

As a friend of mine would say: Hmmmm.

1 kW = 1.359 HP

1 Pound of Coal = 10,000 Btu

1 Kilowatthour of Electricity = 3,412 Btu

1 Gallon of Heating Oil = 139,000 Btu

1 Gallon of Propane = 91,000 Btu

1 Cubic Foot of Natural Gas = 1,021 Btu

1 kg = 2.2 lbs

cubic meters to cubic yards, multiply by 1.31

To convert MPH to M/S divide MPH by 2.2

To convert M/S to MPH multiply M/S by 2.2

1 meter / second = 2.23 mph

1 meter squared = 10.764 feet squared

50 m = 164'; 1 m = 3.28 feet.

Less required backup; Innovations in power generation and delivery

On December 13, 2007 in an article titled Less Backup for Wind Power May Be Required, it describes why integrating wind power and "the grid" is being found as less and less of a "burden."

The varying nature of wind power means that it is harder to forecast than the fluctuations in electricity demand. Adding large quantities of wind power to power systems is therefore challenging. The results of a recent study coordinated by VTT Technical Research Centre of Finland indicate the frequently stated claim of wind power requiring an equal amount of reserve power for backup is not correct.

In areas where wind power production is high during peak demand, wind power can replace other capacity by up to 40% of the installed wind power capacity.

The study showed
  • that a substantial adjustment tolerance is already built into the power network in most countries and
  • the impacts of wind power fluctuations can be further balanced through a variety of measures.
[Outstanding. More food for action to export South Dakota wind power!]

But then reality brings us back to "the real world" with:

Wind power bills rising
"It costs more to be green; regular Xcel customers will pay less as natural gas prices drop," by Gargi Chakrabarty; December 13, 2007.

Xcel's voluntary wind power customers in Colorado will be hit with higher bills beginning next year. But regular customers will benefit from lower electric bills, according to Xcel filings with regulators late Tuesday.

[Until all of the costs of electricity generation- environmental, social, political, transportation, transmission, and management- are weighed in a cost/benefit "spread-sheet," value/ deficiencies will make wind and other alternative energies power an "also-ran."]
