    Reviving Manufacturing with a Federal Cogeneration Policy
    (Georgia Institute of Technology, 2011-10) Brown, Marilyn A. ; Cox, Matthew ; Baer, Paul
    Improving the energy economics of manufacturing is essential to revitalizing the industrial base of advanced economies. This paper evaluates a federal policy option aimed at promoting industrial cogeneration – the production of heat and electricity in a single energy-efficient process. Detailed analysis using the National Energy Modeling System and spreadsheet calculations suggest that industrial cogeneration could meet 18% of U.S. electricity requirements by 2035, compared with its current 8.9% market share. Substituting less efficient utility-scale power plants with cogeneration systems would produce numerous economic and environmental benefits, but would also create an assortment of losers as well as winners. Multiple perspectives to benefit/cost analysis are therefore valuable. Our results indicate that the federal cogeneration policy would be highly favorable to manufacturers and the public sector, cutting energy bills, generating billions of dollars in electricity sales, making producers more competitive, and reducing pollution. Traditional utilities, on the other hand, would likely lose revenues. From a public policy perspective, deadweight losses would be introduced by market-distorting federal incentives (ranging annually from $30 to $150 million), but these losses are much smaller than the estimated net social benefits of the federal cogeneration policy.

    Myths and Facts about Clean Electricity in the U.S. South
    (Georgia Institute of Technology, 2011-09) Brown, Marilyn A. ; Gumerman, Etan ; Sun, Xiaojing ; Kim, Gyungwon ; Sercy, Kenneth
    This paper identifies six myths about clean electricity in the southern U.S. These myths are either propagated by the public at-large, shared within the environmental advocacy culture, or spread imperceptibly between policymakers. Using a widely accepted energy-economic modeling tool, we expose these myths as half-truths and the kind of conventional wisdom that constrains productive debate. In so doing, we identify new starting points for energy policy development. Climate change activists may be surprised to learn that it will take more than a national Renewable Electricity Standard or supportive energy efficiency policies to retire coal plants. Low-cost fossil generation enthusiasts may be surprised to learn that clean generation can save consumers money, even while meeting most demand growth over the next 20 years. This work surfaces the myths concealed in public perceptions and illustrates the positions of various stakeholders in this large U.S. Region.

    Energy Security Dimensions and Trends in Industrialized Countries
    (Georgia Institute of Technology, 2011-06) Brown, Marilyn A. ; Sovacool, Benjamin K. ; Wang, Yu ; D‘Agostino, Anthony Louis
    This article represents one of the first scholarly efforts to correlate actual energy policy and practice with expert views of the multidimensional concept of energy security. Based on the energy security performance of 22 countries in the Organisation for Economic Co-operation and Development between 1970 and 2007, it concludes that many industrialized countries have been unable to make progress toward the goal of achieving secure, reliable and affordable supplies of energy while also transitioning to a low-carbon energy system. However, some national best practices exist, which are identified by examining the relative performance of four countries: the United Kingdom and Belgium (both with noteworthy improvements), and Sweden and France (which have experienced notable slippage in relative performance). The article concludes by offering implications for energy policy more broadly and by providing empirical evidence that our four dimensions of energy security (availability, affordability, energy efficiency, and environmental stewardship) envelop the key strategic dimensions of energy security.

    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.

    Meta-Review of Efficiency Potential Studies and Their Implications for the South
    (Georgia Institute of Technology, 2009-08) Chandler, Sharon (Jess) Ann ; Brown, Marilyn A.
    This paper reviews 19 separate studies published over the past 12 years that examine the potential for deploying greater energy efficiency in the South. These studies contain more than 250 estimates of the energy efficiency potential for different fuels (electricity, natural gas, and all fuels), sectors of the economy (residential buildings, commercial buildings, and industry), and types of potential (technical, economic, maximum achievable, and moderate achievable). The meta-review concludes that a reservoir of cost-effective energy savings exists in the South. The full deployment of these nearly pollution-free opportunities could largely offset the growth in energy consumption forecast for the region over the next decade.

    Competing Dimensions of Energy Security: An International Perspective
    (Georgia Institute of Technology, 2009-01-13) Sovacool, Benjamin K. ; Brown, Marilyn A.
    How well are industrialized nations doing in terms of their energy security? Without a standardized set of metrics, it is difficult to determine the extent that countries are properly responding to the emerging energy security challenges related to climate change, growing dependence on fossil fuels, population growth and economic development. In response, we propose the creation of an Energy Security Index to inform policymakers, investors and analysts about the status of energy conditions. Using the United States and 21 other member countries of the Organization for Economic Cooperation and Development (OECD) as an example, and looking at energy security from 1970 to 2007, our index shows that only four countries¡ªBelgium, Denmark, Japan, and the United Kingdom¡ªhave made progress on multiple dimensions of the energy security problem. The remaining 18 have either made no improvement or are less secure. To make this argument, the first section of the article surveys the scholarly literature on energy security from 2003 to 2008 and argues that an index should address accessibility, affordability, efficiency, and environmental stewardship. Because each of these four components is multidimensional, the second section discusses ten metrics that comprise an Energy Security Index: oil import dependence, percentage of alternative transport fuels, on-road fuel economy for passenger vehicles, energy intensity, natural gas import dependence, electricity prices, gasoline prices, sulfur dioxide emissions, and carbon dioxide emissions. The third section analyzes the relative performance of four countries: Denmark (the top performer), Japan (which performed well), the United States (which performed poorly), and Spain (the worst performer). The article concludes by offering implications for policy. Conflicts between energy security criteria mean that advancement along any one dimension can undermine progress on another dimension. By focusing on a 10-point index, public policy can better illuminate such tradeoffs and can identify compensating policies.

    Potential Impacts of Energy and Climate Policies on the U. S. Pulp and Paper Industry
    (Georgia Institute of Technology, 2008-06-09) Brown, Marilyn A. ; Atamturk, Nilgun
    Many energy and climate policies are being debated in the United States that could have significant impact upon the future of the pulp and paper industry. Five of these policies are examined here in terms of their possible directional influences on biomass energy and paper production: (1) a national renewable electricity standard, (2) a U.S. greenhouse gas cap and trade system, (3) stronger renewable fuels standards, (4) expanded state incentives for biomass pilot plants, and (5) more favorable taxation of forest property. The observed trends reinforce the value of forest product diversification through the addition of biomass power generation and transportation fuels/chemicals production as co-products of the pulp and paper industry. Therefore, directing capital expenditures to the increasingly cost-competitive and expanding biopower and biofuels markets would appear to have merit in anticipation of the promulgation of new energy and climate legislation. Accelerated investments in new facilities such as biorefineries and cogeneration units and in energy-efficiency upgrades would position the pulp and paper industry to profit from current trends and likely policy initiatives.

    The Transportation Energy and Carbon Footprints of the 100 Largest U.S. Metropolitan Areas
    (Georgia Institute of Technology, 2008-05-23) Southworth, Frank ; Sonnenberg, Anthon ; Brown, Marilyn A.
    In this paper we present estimates of the automobile and truck travel based energy and carbon footprints of the largest 100 U.S. metropolitan areas. The footprints are based on the estimated vehicle miles traveled and the transportation fuels consumed. Results are presented on an annual basis and represent end use emissions only. Total carbon emissions, emissions per capita, and emissions per dollar of gross metropolitan product are reported. Two years of annual data were examined, 2000 and 2005, with most of the in-depth analysis focused on the 2005 results. In section 2 we provide background data on the national picture and derive some carbon and energy consumption figures for the nation as a whole. In section 3 of the paper we examine the metropolitan area-wide results based on the sums and averages across all 100 metro areas, and compare these with the national totals and averages. In section 4 we present metropolitan area specific footprints and examine the considerable variation that is found to exist across individual metro areas. In doing so we pay particular attention to the effects that urban form might have on these differences. Finally, section 5 provides a summary of major findings, and a list of caveats that need to be borne in mind when using the results due to known limitations in the data sources used.
