Renewable energy and conservation
Alternative and sustainable energy sources are critically needed for the United States. Currently, fossil fuels provide more than 85% of all the energy consumed in the United States, about two-thirds of our electricity, and nearly all of our transportation fuels. Plant biomass is being promoted to produce electricity, liquid fuels (ethanol and butanol), and heat, but bioenergy currently accounts for only three percent of the primary energy production in the United States.
The corn-based ethanol industry has experienced unprecedented growth demonstrating the potential of biofuel markets. Unfortunately, the extensive use of corn as a feedstock creates a myriad of economic, social, and environmental issues that are challenging the long-term sustainability of its use.
Alternative sources of feedstock for energy production, such as cellulosic biomass, are being proposed to meet energy demands while addressing key environmental and social issues. Successful cellulosic Bioenergy industries will be dependent on the development of efficient conversion technologies, a robust supply of feedstock in known quantity and quality, and equitable financial incentives for farmers.
Cellulosic feedstocks that have been identified include agriculture crop residues from small grain and corn; dedicated energy crops such as switchgrass, willow, hybrid, poplar, and native prairies; and forest residue. Perennial biomass crops are especially exciting as feedstock for production of biofuels and valuable co-products while increasing biological diversity on the landscape, conserving soil and water resources, maintaining ecosystem productivity and health, and balancing the global carbon cycle.
University of Minnesota initiatives
The College of Food, Agricultural and Natural Resource Sciences (CFANS) and the Initiative on Renewable Energy and the Environment (IREE) have established the University of Minnesota as a National Center for Biofuels Research, Renewable Energy, and Bio-based products. The overall goals are to: 1) conduct fundamental research on plants and microbes to develop genomics-based solution for renewable energy sources and 2) develop economically feasible and ecologically sustainable solutions for producing biofuels from cellulosic biomass and other biological sources, especially as it pertains to the development of new feedstock genotypes.
University of Minnesota Extension will be the outreach arm of the University in disseminating renewable energy technology, research, education, and energy feedstock information to the public in the years to come.
