Renewable Energy Roadmap: Rural America Can Prosper

Report from the University of Tennessee finds the 25x25 goal will boost farm income and create millions of jobs.

A new economic analysis conducted by researchers at the University of Tennessee outlines how America's vast natural resources can be tapped to produce 25 percent of the nation's energy supply from renewable sources by 2025. With continued advancements in technology and significant shifts in cropping patterns, U.S. farmers, ranchers and foresters can contribute to this energy goal while still providing abundant supplies of food, feed and fiber. While a variety of renewable energy resources, including wind, hydro, solar, and geothermal, would be needed to meet the goal, the study principally examines the impact of producing the amount of biomass needed from agriculture and forestry.

Based on information from the RAND study, it is estimated that, by 2025, 12.10 quads will be annually produced from geothermal, solar photovoltaic, hydro, and wind generation. The sum of those two is 13.97 quads. Therefore, to meet the 25x'25 goal of 29.42 quads, an additional 15.45 quads would need to come from agricultural and forestry lands.

Executive Summary

This study was designed to determine the feasibility of America's farms, forests and ranches providing 25 percent of U.S. total energy needs while continuing to produce safe, abundant and affordable food, feed and fiber.

In addition, the analysis looks at the associated impacts of achieving the goal on the agricultural sector and the nation's overall economy. The 25x'25 Project Steering Committee established the "25x'25" vision and, along with Energy Future Coalition and the Energy Foundation, financed the study. The analysis was conducted by a team of professors and analysts from the University of Tennessee (UT) during 2005-2006.

According to the U.S. Dept. of Energy (DOE), estimated energy use in 2005 was 100.5 quads. Based on DOE estimates and a recent RAND study, the nation will annually consume about 117.7 quads of energy by 2025. A quad is a quadrillion BTUs. To put a quad in perspective, about 4.4 million households would consume a quad of energy through electricity and gasoline use in one year.

To meet the 25x'25 vision, 25 percent of the projected 117.7 quads, or 29.42 quads (henceforth referred to as the "All Energy" or AE scenario), are needed from renewable energy sources. At present, an estimated 1.87 quads are produced from biomass (agricultural/forestry) resources in the production of electricity and/or heat. Based on information from the RAND study, it is estimated that, by 2025, 12.10 quads will be annually produced from geothermal, solar photovoltaic, hydro, and wind generation. The sum of those two is 13.97 quads. Therefore, to meet the 25x'25 goal of 29.42 quads, an additional 15.45 quads would need to come from agricultural and forestry lands.

A second scenario examining the impacts of producing 25% of the nation's electric power and motor vehicle fuels (hereafter the "EPT" scenario) was also performed, to parallel the findings of the RAND report. This scenario produced smaller benefits than the "All Energy" case, with smaller effects on land use and feed crop prices.

Key findings in this analysis:

* America's farms, forests and ranches can play a significant role in meeting the country's renewable energy needs.

* The 25x'25 goal is achievable. Continued yield increases in major crops, strong contributions from the forestry sector, utilization of food processing wastes, as well as the use of over one hundred million acres of dedicated energy crops, like switchgrass, will all contribute toward meeting this goal. A combination of all of these new and existing sources can provide sufficient feedstock for the additional 15.45 quads of renewable energy needed.

* The 25x'25 goal can be met while allowing the ability of the agricultural sector to reliably produce food, feed and fiber at reasonable prices.

* Reaching the goal would have an extremely favorable impact on rural America and the nation as a whole. Including multiplier effects through the economy, the projected annual impact on the nation from producing and converting feedstocks into energy would be in excess of $700 billion in economic activity and 5.1 million jobs in 2025, most of that in rural areas.

* By reaching the 25X'25 energy goal, the total addition to net farm income could reach $180 billion, as the market rewards growers for producing alternative energy and enhancing ii our national security. In 2025 alone, net farm income would increase by $37 billion compared with USDA baseline projections.

* Reaching the goal would also have significant positive price impacts on crops. In the year 2025, when compared with USDA baseline projections, national average per bushel crop prices are projected to be $0.71 higher for corn, $0.48 higher for wheat, and $2.04 higher for soybeans.

* With higher market prices, an estimated cumulative savings in government payments of $15 billion could occur. This does not include potential savings in fixed/direct or Conservation Reserve Program (CRP) payments.

* In the near term, corn acres are projected to increase. As cellulosic ethanol becomes commercially viable after 2012, the analysis predicts major increases in acreage for a dedicated energy crop like switchgrass.

* The higher feed crop prices do not result in a one-to-one increase in feed expenses for the livestock industry. Increases in ethanol and biodiesel production result in more distillers dried grains (DDG's) and soybean meal, which partially compensate for increased corn prices. Moreover, the integrated nature of the industry allows for the adjustment of animal inventories as a way to adjust to the environment and increase net returns. In addition, the production of energy from manure and tallow could provide additional value for the industry.

* Contributions from America's fields, farms and forests could result in the production of 86 billion gallons of ethanol and 1.2 billion gallons of biodiesel, which has the potential to decrease gasoline consumption by 59 billion gallons in 2025. The production of 14.19 quads of energy from biomass and wind sources could replace the growing demand for natural gas, diesel, and/or coal generated electricity. These renewable energy resources could significantly decrease the nation's reliance on foreign oil, fossil fuels, and enhance the national security of all Americans.

I sent this new, some what orphaned, soil technology to the 25x25 orginisation, it speaks to so many different interests and disciplines that it has not been embraced fully by any. I hopr they will see both the potential of this system and the convergence needed for it's implementation.

The integrated energy strategy offered by Terra Preta Soil technology may
provide the only path to sustain our agricultural and fossil fueled power
structure without climate degradation, other than nuclear power.

These are processes where you can have your Bio-fuels, CO2 sequestration and fertility too.

Harnessing the work of this vast number of microbes and fungi changes the whole equation of EROEI for food and Bio fuels. I see this as the only sustainable agricultural strategy if we no longer have cheap fossil fuels for fertilizer.

The article completely ignores solar-thermal technology, which has a great potential to provide renewable energy - both to the power grid, and directly for heating and cooling purposes. Agricultural energy is not very effective when based on grain feedstocks, but may well be a lot better, based on sweet sorghum and sugar beets - and eventually switchgrass, when the technology becomes cost-effective. However, none of these technologies will be successful until they become self-sustaining, without rebates, subsidies, etc.

MANDATORY RENEWABLE ENERGY - THE ENERGY EVOLUTION -R3

The implementation of mandatory renewable energy could be done on a gradual scale over the next 10 years. At the end of the 10 year period all construction and energy use in the structures throughout the United States must be 100% powered by renewable energy.

In addition, the governments must impose laws, rules and regulations whereby the utility companies must comply with a fair "NET METERING" (the buying of excess generation from the consumer), including the promotion of research and production of "renewable energy technology" with various long term incentives and grants. The various foundations in existence should be used to contribute to this cause.

A mandatory time table should also be established for the automobile industry to produce an automobile powered by renewable energy. This is a way to expedite our energy independence and economic growth.

Dream on! The total amount of biomass produced by the sun in the USA each year, including forest, crops, roots of trees, sagebrush and weeds, is on the order of 75 quads. The notion of deriving ~15 quads of commercial energy from photosynthesis is utterly preposterous and irresponsible. This is more than all the energy in crops that are currently grown, with no energy conversion losses, no accounting for soil or water source degradation. See http://www.oilcrisis.com/junkscience/.

The 25 X 25 plan may be about moving money to the folks that have lots.

How about:

Corn ethanol maybe the oil guys best friend.

The $0.51 per gal. corporate welfare to the oil refiners for adding 5.6% ethanol to California gas is about $500,000,000.00 per year.

The ethanol may add over $1.00 per gal. to the gas profit in California.

That may be about $100 billion in oil profit from California motorists.

The science is interesting but so is the money.

A $4 billion Prop. 87 oil tax may add $40 billion in oil profit.
