    Renewable energy in the South: a policy brief
    (Georgia Institute of Technology, 2010-07) Brown, Marilyn A. ; Gumerman, Etan ; Baek, Youngsun ; Morris, Cullen ; Wang, Yu
    This working paper assesses the economic potential of renewable electricity generation in the South under alternative policy scenarios. Using a customized version of the National Energy Modeling System (NEMS), we examine the impact of 1) expanded and updated estimates of renewable resources, 2) a Renewable Portfolio Standard (RPS), and 3) a Carbon-Constrained Future (CCF). Under the Expanded Renewables Scenario, renewable electricity generation doubles the output of the Reference forecast for the South. If a Federal RPS is imposed or the policies represented by our CCF scenario are implemented, we estimate that 15% to 30% of the South’s electricity could be generated from renewable sources. Among the renewable resources, wind, biomass, and hydro are anticipated to provide the most generation potential. As the integration of renewable sources expands through the modeled time horizon, wind gradually out-competes biomass in the renewable electricity market. Cost-effective customer-owned renewables could also contribute significantly to electricity generation by 2030 in the South, under supportive policies.

    The Forest Products Industry at an Energy/Climate Crossroads
    (Georgia Institute of Technology, 2010-06) Brown, Marilyn A. ; Baek, Youngsun
    Transformational energy and climate policies are being debated worldwide that could have significant impact upon the future of the forest products industry. Because woody biomass can produce alternative transportation fuels, low-carbon electricity, and numerous other “green” products in addition to traditional paper and lumber commodities, the future use of forest resources is highly uncertain. Using the National Energy Modeling System (NEMS), this paper assesses the future of the forest products industry under three possible U.S. policy scenarios: (1) a national renewable electricity standard, (2) a national policy of carbon constraints, and (3) incentives for industrial energy efficiency. In addition, we discuss how these policy scenarios might interface with the recently strengthened U.S. renewable fuels standards. The principal focus is on how forest products including residues might be utilized under different policy scenarios, and what such market shifts might mean for electricity and biomass prices, as well as energy consumption and carbon emissions. The results underscore the value of incentivizing energy efficiency in a portfolio of energy and climate policies in order to moderate electricity and biomass price escalation while strengthening energy security and reducing CO2 emissions.

    Reinventing Industrial Energy Use in a Resource-Constrained World
    (Georgia Institute of Technology, 2010-02) Brown, Marilyn A. ; Cortes, Rodrigo ; Cox, Matthew
    In an increasingly resource-constrained world, improving the energy efficiency of industry is essential. In addition to its environmental, security, and competitiveness benefits, energy efficiency delivers a return on investment that contributes to the profitability of enterprises. Using international technology and policy benchmarking, this chapter examines the energy productivity of U.S. industry and its role as a technology innovator, supplying next-generation green and clean technologies. After reviewing the barriers and drivers of improved practices, the chapter concludes that the dual goals of advancing energy efficiency at industrial plants and advancing product innovation are critical to promoting the more productive consumption of energy in a resource-constrained world.
