| This study examines the rapidly expanding biofuels industry and identifies challenges for producer-owned biofuel projects. The U.S. ethanol industry has been growing rapidly, and biodiesel production is poised for similar growth. Producer involvement is driven by the desire to add value to farm commodities and the impact of biofuel projects on local grain prices. Local state and federal incentives have also stimulated producer interest. The long-run profitability of biofuel projects is driven by feedstock availability, access to market centers for biofuels, access to markets for coproducts, and utility costs and availability. The rapidly increasing size and scale of ethanol and biodiesel plants make it difficult for producers to fund these projects.... |

| This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail... |

| Over the last few years, the production of renewable fuels has increased dramatically. Rising oil prices, limited supplies of fossil fuel, and increased concerns about global warming have created a growing demand for renewable energy sources. Both the ethanol and biodiesel industries have experienced tremendous growth in the past few years. The production of these fuels is highly dependent on the availability of agricultural feedstocks. This research examined the covariability between crude oil prices and corn, sorghum, sugar, soybeans, soybean oil, and palm oil prices during the 2003-2007 time period. Johansen cointegration tests revealed no cointegrating relationships during the 2003-2005 time frame. However, corn prices and soybean prices were... |

| This paper addresses the timing and interdependence between innovation and environmental policy in a model of research and development (R&D). On a first-best path the environmental tax is set at the Pigouvian level, independent of innovation policy. With infinite patent lifetime, the R&D subsidy should be constant and independent of the state of the environment. However, with finite patent lifetime, optimal innovation policy depends on the stage of the environmental problem. In the early stages of an environmental problem, abatement research should be subsidized at a high level and this subsidy should fall monotonically over time to stimulate initial R&D investments. Alternatively, with a constant R&D subsidy, patents’ length should... |

| China’s emerging standing in the world demands a major rethinking of its diplomatic strategies. Given its population size, geographical scale, economic power and military presence, China is poised to play a larger political role in the twenty-first century, and is thus perceived by the international community to have greater capacities, capabilities and responsibilities. At the same time, environmental stresses caused by China’s energy and resources demands have become increasingly evident in recent years, urging China to cultivate delicate diplomatic relations with its neighbors and strategic partners. Tensions have been seen in areas such as transboundary air pollution, cross-border water resources management and resources exploitation, and more recently... |

| For the mitigation of long-term pollution threats, one must consider that both the process of environmental degradation and the switchover to new and cleaner technologies are dynamic. We develop a model of a uniform good that can be produced by either a polluting technology or a clean one; the latter is more expensive and requires investment in capacity. We derive the socially optimal pollution stock accumulation and creation of nonpolluting production capacity, weighing the tradeoffs among consumption, investment and adjustment costs, and environmental damages. We consider the effects of changes in the pollution decay rate, the capacity depreciation rate, and the initial state of the environment on both the steady state and the transition period. The... |

| We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market multi-commodity international FAPRI model. The model incorporates the tradeoffs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China, EU, and India, and compute shock multipliers for... |

| The Southeastern United States depends on coal to supply 60% of its electricity needs. The region leads in CO2 emissions and ranks second in emissions of SO2 and NO2. Compared with coal, biomass feedstocks have lower emission levels of sulfur or sulfur compounds and can potentially reduce nitrogen oxide emissions. This study examines the economic impacts of cofiring level scenarios. Economic impacts are estimated for producing, collecting, and transporting feedstock; retrofitting coal-fired utilities for burning feedstock; operating cofired utilities; and coal displaced from burning the feedstock. |

| As a result of the increase in the real cost of fossil fuel-based energy in recent years, federal and state governments have taken a more active role in energy policy by creating incentives to develop alternative sources of energy, including biofuels. However, policymakers often become focused on the specific type of energy and not the energy services consumers ultimately value. The lack of recognition of energy as a commodity results in policies that ignore the characteristics of the associated markets: easy entry and exit, no barriers to entry, and sensitivity to changes in supply and demand. Consequently, energy industries may fail to arise because entrepreneurs must be able to account for all costs and earn—at a minimum—a competitive return on the... |

| This study provides an evaluation of the performance of five renewable energy technologies used to generate electricity: biomass, geothermal, solar photovoltaics, solar thermal, and wind. We compared the actual performance of these technologies against stated projections that helped shape public policy goals over the last three decades. Our findings document a significant difference between the success of renewable technologies in penetrating the U.S. electricity generation market and in meeting cost-related goals, when compared with historic projections. In general, renewable technologies have failed to meet expectations with respect to market penetration. They have succeeded, however, in meeting or exceeding expectations with respect to their cost. To a... |
