Policy, Energy, and Other Related Issues

Effects of Increased Biofuels on the U.S. Economy in 2022PDF file, 1.15MB (October 2010). Achieving greater energy security by reducing dependence on foreign petroleum is a goal of U.S. energy policy. The Energy Independence and Security Act of 2007 (EISA) calls for a Renewable Fuel Standard (RFS-2), which mandates that the United States increase the volume of biofuel that is blended into transportation fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022. Long-term technological advances are needed to meet this mandate. This report examines how meeting the RFS-2 would affect various key components of the U.S. economy. If biofuel production advances with cost-reducing technology and petroleum prices continue to rise as projected, the RFS-2 could provide economy wide benefits. However, the actual level of benefits (or costs) to the U.S. economy depends importantly on future oil prices and whether tax credits are retained in 2022. If oil prices stabilize or decline from current levels and tax credits are retained, then benefits to the economy would diminish.

2008 Energy Balance for the Corn-Ethanol Industry (June 2010). The Agricultural Resource Management Survey of corn growers for the year 2005 and the 2008 survey of dry mill ethanol plants are used to estimate the net energy balance of corn ethanol. This report measures all conventional fossil fuel energy used in the production of 1 gallon of corn ethanol.

Ethanol and a Changing Agricultural Landscape (November 2009). The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuels in the United States. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional agricultural production and the environment.

Full Throttle U.S. Ethanol Expansion Faces Challenges Down the Road (September 2009). The Energy Independence and Security Act of 2007 specified an ambitious agenda to significantly expand biofuel use in the United States, with an increased emphasis on “second generation” cellulosic biofuel. However, challenges in both supply and demand may limit future growth in the industry, ranging from the development of new cellulosic biofuel production technologies to the development of supporting infrastructures at every step along the way from the field to the pump.

Growing Crops for Biofuels Has Spillover Effects (March 2009). Federal mandates for biofuel production promote expanded crop acreage and shifts in cropping patterns and livestock production due to higher prices for corn and other grain crops. Research that improves crop productivity and conversion efficiency, as well as conservation practices like no-till and buffer strips, could lessen the environmental impacts of biofuels.

Increasing Feedstock Production for Biofuels: Economic Drivers, Environmental Implications, and the Role of ResearchPDF file, 9.74MB (December 2008). The implications of increased demand for feedstocks to meet the Nation's biofuels goals are uncertain. Questions include what types of feedstocks will be used, at what prices, grown where, and with what implications for greenhouse gases and sustainability? A report released by the interagency Biomass Research and Development Board addresses these issues, including analysis of scenarios for specific biofuel targets with alternative assumptions about key variables like crop productivity and input prices.

The Economics of Biomass Feedstocks in the United States: A Review of the LiteraturePDF file (October 2008). A review of economic studies available through the end of 2007 intended to support further economic research on expanding the production of renewable fuels.

2008 Farm Bill Side By Side2008 Farm Bill Side-By-Side (August 2008). A title-by-title summary of key provisions of the 2008 Act in a side-by-side comparison with previous legislation. The side-by-side includes links to related ERS publications and to analyses of previous farm acts. New features include a user's guide, an A-Z list of major provisions, and a search function.


Ethanol Transportation BackgrounderPDF file, 1.15MB (September 2007). An overview of transportation issues facing a rapidly expanding U.S. ethanol industry in the context of the U.S. corn market from USDA's Agricultural Marketing Service.

USDA 2007 Farm Bill Theme Paper: Energy and AgriculturePDF file (August 2006) describes the role of U.S. agriculture in energy production and efforts to conserve energy use in agriculture, discusses and evaluates energy programs administered by USDA, and concludes with a discussion of general policy approaches associated with energy and agriculture.

Agriculture and Rural Communities Are Resilient to High Energy Costs (April 2006). Rising energy prices may prompt farmers and rural residents to make tradeoffs in their production practices and daily lives. Farmers may be induced to adopt farming practices that use less energy. Transportation costs are higher for rural residents, while heating costs are roughly the same for rural and urban residents.

Biodiesel Development: New Markets for Conventional and Genetically Modified Agricultural Products (September 1998). With environmental and energy source concerns on the rise, using agricultural fats and oils as fuel in diesel engines has captured increasing attention. Substituting petroleum diesel with biodiesel may reduce air emissions, increase the domestic supply of fuel, and create new markets for farmers.

Industrial Uses of Agricultural Materials (1993-97). Agricultural producers provide industry with raw materials for a vast array of nonfood industrial and consumer products. The seven reports provide economic and market context for new and ongoing industrial uses of agricultural materials, such as ethanol and biodiesel.

Estimating the Net Energy Balance of Corn Ethanol (July 1995). Variations in data and assumptions used among studies estimating the net energy value of corn ethanol have resulted in a wide range of estimates. This report identifies the factors causing the variation and develops a more consistent estimate. The net energy value of corn ethanol has become positive in recent years due to technological advances in ethanol conversion and increased efficiency in farm production.

Biofuels and Agricultural Commodity Markets

Feed Outlook (monthly). This report examines supply, use, prices, and trade for feed grains, with a focus on corn. New information on corn used for ethanol production is covered in the text as well as in Table 5 (Corn: Food and industrial uses).

Oil Crops Outlook (monthly). This report analyzes recent trends and emerging developments for the U.S. and international vegetable oils markets. For the production of biodiesel, these oils provide the primary feedstock and are its main cost. Thus, market information on vegetable oil supply and demand is vital for the production economics of this rapidly growing biofuel.

Market Issues and Prospects for U.S. Distillers’ Grains Supply, Use, and Price RelationshipsPDF file, 4.34MB(December 2010). Growth in corn dry-mill ethanol production has surged in the past several years, simultaneously creating a co-product—distillers’ grains (DDGS). Many in the U.S. feed industry were concerned about the size of this new feed source and whether it could be used entirely by the feed industry, but they also worried about the price discovery process for the product. The authors of this report provide a transparent methodology to estimate U.S. supply and consumption of DDGS. Potential domestic and export use of U.S. DDGS exceeds current production and is likely to exceed future production as ethanol production continues to grow. The authors identify the DDGS price discovery process along with the price relationships of distillers’ grains, corn, and soybean meal.

Next-Generation Biofuels: Near-Term Challenges and Implications for Agriculture (May 2010). This report assesses the short-term outlook for production of next-generation biofuels and the near-term challenges facing the sector. See related Amber Waves feature, Next-Generation Biofuels: Near-Term Challenges and Implications for Agriculture (June 2010).

Ethanol Co-Product Use in U.S. Cattle Feeding: Lessons Learned and Considerations (April 2009) examines evolution of ethanol-industry byproducts to "co-products" that have market value separate from primary products. Co-products such as dried distiller's grains, corn gluten feed, corn gluten meal, corn oil, and brewer's grains have become economically viable components, along with traditional ingredients such as corn, soybean meal, and urea in feed rations.

Grain Prices Impact Entire Livestock Production Cycle (March 2009). Changes in U.S. livestock-industry structure and the use of alternative feeds, such as byproducts from ethanol production, will help reduce the impact of higher input costs on livestock producers.

Ethanol Expansion in the United States: How Will the Agricultural Sector Adjust? (May 2007). Corn is currently the primary feedstock for ethanol in the United States. Market impacts of the expansion in ethanol production extend well beyond the corn sector to supply and demand for other crops, such as soybeans and cotton, as well as to U.S. livestock industries. As a consequence of these commodity market impacts, farm income, government payments, and food prices also change. See narrated slideshow for an overview; see related Amber Waves feature U.S. Ethanol Expansion Driving Changes Throughout the Agricultural Sector (September 2007).

An Analysis of the Effects of an Expansion in Biofuel Demand on U.S. AgriculturePDF file, 1.15MB (May 2007). This analysis assesses the effects on agriculture of further expansion of biofuels production than that in USDA’s February 2007 long-term projections and reviews the potential for cellulosic ethanol production. Two scenarios were developed to evaluate the effects of biofuel production on crop markets, national and regional livestock markets, farm income, and the environment for crop years 2007-16.

Ethanol Reshapes the Corn Market (May 2007). Work is underway to add billions of gallons to the annual production capacity of the fuel ethyl alcohol market. Expanded ethanol production in the United States has helped to reduce corn ending stocks and boost corn prices.

Feed Grains Backgrounder (March 2007). The rapidly expanding use of corn by the ethanol industry is raising issues throughout U.S. agriculture, including the implications of using grain for fuel instead of for food or feed and the adequacy of future grain supplies. This report addresses key market and policy developments that have affected the U.S. feed grains sector in recent years. During the ongoing farm policy debate, the U.S. feed grain sector faces uncertainty about the future level and type of government support. For the related AmberWaves finding, see Ethanol Reduces Government Support for U.S. Feed Grain Sector (April 2007).

Soybean Backgrounder (April 2006). Key domestic and international market and policy developments have affected the U.S. soybean sector in recent years. The report also covers the development of nontraditional soybean uses such as biodiesel, which is becoming an important new source of demand for soybean oil. For the related AmberWaves finding, see International Trade, Biofuel Initiatives Reshaping the Soybean Sector (September 2006).

Agricultural Baseline Projections: Current and Previous Baseline Projections (annually in February). The USDA baseline report provides longrun (10-year) projections for the agricultural sector. Projections cover agricultural commodities, agricultural trade, and aggregate indicators of the sector, such as farm income and food prices. Energy and bioenergy issues and impacts are discussed in various sections of the report.

Global Biofuels

China Is Using More Corn for Industrial Products (December 2009). Use of corn to make starch, sweeteners, ethyl alcohol, and other industrial products has accounted for most of the growth in China’s corn use over the past decade. Despite the surge in industrial use, China still has a surplus of corn. The country’s exports of corn-based industrial products have grown as exports of unprocessed corn receded. Industrial processing was encouraged by government policy early in the decade. Industrial processors in China benefited from policies that kept domestic corn prices from rising in 2007/08, but many experienced losses in 2008/09 when demand slowed and the government supported corn prices.

Colombia: A New Ethanol Producer on the Rise? (January 2009). Colombia's sugarcane-based ethanol industry, after operating for only 3 years, is the second most developed in the Western Hemisphere. Colombia's sugarcane-based ethanol production is increasing; proposed expansion projects have the potential to more than triple daily production from 277,000 gallons in 2007 to almost 1 million gallons in 2010.

The Future of Biofuels: A Global Perspective (November 2007). Global biofuel production tripled between 2000 and 2007, but still accounts for less than 3 percent of the transportation fuel supply worldwide. Biofuels will likely be part of a portfolio of solutions to high energy prices, including conservation, more efficient energy use, and use of other alternative fuels.

Pacific Food System Outlook 2006-07 The Future Role of BiofuelsPDF file, 4.34MB (November 2006). Unlike previous periods of high oil prices, the current increase in oil prices is having a fundamentally different impact on the food system, creating a more sustained interest in agriculture as a supplier of energy, not just a consumer. Prospects for Pacific Rim agriculture to be a supplier of energy are the focus of this report, which is based on two days of discussion at the 10th annual Pacific Food System Outlook meeting in Singapore in May 2006.

Brazil's Booming Agriculture Faces Obstacles (November 2006). Brazil has emerged as an important player in global food and agricultural markets. Brazil’s sugarcane and associated sugar and ethanol industries have grown rapidly in the last 5 years, and the country has become the world’s largest exporter of sugar and ethanol.

Biofuels and Food Prices

Agricultural Commodity Price Spikes in the 1970s and 1990s: Valuable Lessons for Today (March 2008) examines the recent runup in commodity prices in light of similar occurrences in 1971-74 and 1994-96. Although similar to those earlier price runups, rising demand for grains and oilseeds for biofuels adds a new dimension of complexity.

Rising Food Prices (September 2008). The Consumer Price Index (CPI) for all food has been rising at an accelerated rate in 2007 and 2008, a trend that is expected to continue into the first half of 2009. Higher commodity and energy costs are responsible for higher retail prices. The main factors behind higher food commodity costs include stronger global demand for food, increased U.S. agricultural exports resulting from stronger demand and a weaker dollar, weather-related production problems in some areas of the world, and the increased use of some food commodities, such as corn, for bioenergy uses (requires Windows Media Player).

Fluctuating Food Commodity Prices: A Complex Issue With No Easy Answers (November 2008) explores the many factors that contributed to the rapid escalation of food commodity prices through mid-2008. For the full report, see Global Agricultural Supply and Demand: Factors Contributing to the Recent Increase in Food Commodity Prices (July 2008).

Rising Food Prices Intensify Food Insecurity in Developing Countries (February 2008). The use of food crops for biofuels, coupled with greater food demand, has reversed the path of declining price trends for several commodities. For highly import-dependent or highly food-insecure countries, any decline in import capacity stemming from rising food prices can have challenging food security implications. Food aid, a key safety net source, has stagnated during the last two decades, and its share has declined relative to total food imports of low-income countries.

Corn Prices Near Record High, But What About Food Costs? (February 2008). This Amber Waves article traces the effect of higher corn prices on U.S. retail food prices by analyzing data on price trends from 1987-2007 and the price responsiveness of corn-dependent food to cost changes. The results indicate ethanol's impact on retail food prices depends on how long the increased demand for corn raises farm corn prices and the extent to which higher corn prices are passed through to retail.

Rising Food Prices (June 2007). Retail food price inflation has accelerated in 2007 as higher commodity and energy prices have begun to work their way through the food price system. This short USDA news video focuses on the main factors impacting retail food price inflation and provides insight into what is likely to occur for the rest of the year (requires Windows Media Player).

Ethyl Alcohol Becomes a Global Commodity (April 2005). Most ethyl alcohol used in the U.S. is produced domestically. However, sharp increases in U.S. ethanol use in 2004 pushed prices high enough to stimulate imports, despite duties matching the blender tax received by U.S. producers of alcohol used for fuel.
