Green Pricing, Mary Finley-Brook, Charles Kline Jan 2011

Green Pricing, Mary Finley-Brook, Charles Kline

Geography and the Environment Faculty Publications

Green pricing is commonly found in energy markets and finances environmentally friendly alternatives to conventional utilities. Interested customers pay an additional fee per kilowatt-hour to purchase clean energy from hydroelectric, wind, geothermal, solar, and biomass sources. Green power markets are still new, and to ensure quality and verify delivery, many utilities apply for certification from independent organizations. Renewable energy credits (RECs) are another method to assist utility companies in financing green energy investments. Although the REC purchaser does not directly buy electricity, REC sales may subsidize renewable energy production.

Institute for Sustainable Solutions Publications and Presentations

Many contemporary societal challenges manifest themselves in the domain of human?environment interactions. There is a growing recognition that responses to these challenges formulated within current disciplinary boundaries, in isolation from their wider contexts, cannot adequately address them. Here, we outline the need for an integrated, transdisciplinary synthesis that allows for a holistic approach, and, above all, a much longer time perspective. We outline both the need for and the fundamental characteristics of what we call ?integrated history.? This approach promises to yield new understandings of the relationship between the past, present, and possible futures of our integrated human?environment system. We …

Historically, economic development has been strongly correlated with increasing energy use and growth of greenhouse gas (GHG) emissions. Renewable energy (RE) can help decouple that correlation, contributing to sustainable development (SD). In addition, RE offers the opportunity to improve access to modern energy services for the poorest members of society, which is crucial for the achievement of any single of the eight Millennium Development Goals.

Theoretical concepts of SD can provide useful frameworks to assess the interactions between SD and RE. SD addresses concerns about relationships between human society and nature. Traditionally, SD has been framed in the three-pillar model—Economy, …

Is Strategic Management (Still) Responsible For The Demise Of Society?, Nancy E. Landrum, Sandra Edwards Jan 2011

Is Strategic Management (Still) Responsible For The Demise Of Society?, Nancy E. Landrum, Sandra Edwards

School of Environmental Sustainability: Faculty Publications and Other Works

Over fourteen years ago, Bill Richardson stated that modern strategic management is leading to the demise of society with its profit-maximization focus. Furthermore, there is criticism that strategic management research is lacking relevance for practitioners. In contrast to this criticism of academia, practitioners are increasingly engaged in sustainability-related activities and reporting and are moving beyond the historical focus on profits. This study examined trends in strategic management academic and practitioner publications since Richardson's claim. Since academicians are charged with educating future managers for the workforce, we sought to determine if academic strategic management research publications are reflecting the practitioner sustainability …


Development Of An Expert System To Aid In The Selection Of Sustainability Design Engineering Methods, Pedro Renato Acosta Jan 2011

Development Of An Expert System To Aid In The Selection Of Sustainability Design Engineering Methods, Pedro Renato Acosta

Open Access Theses & Dissertations

The objective of this thesis is to present the development of an expert system to aid designers in the selection of design methods, in particular for sustainability methods. When practicing engineers need help in their design process, they look for design methods and tools; this is a challenge especially for inexperienced engineers in the sustainability area. Engineers, due to time constrains, will only utilize one or few methods during their professional life. The origin of this situation can be traced to engineering education, where it is typical that an instructor prefers one or few methods in particular, and even when …

Cross-Scale Value Trade-Offs In Managing Social-Ecological Systems: The Politics Of Scale In Ruaha National Park, Tanzania, Asim Zia, Paul Hirsch, Alexander Songorwa, David R. Mutekanga, Sheila O'Connor, Thomas Mcshane, Peter Brosius, Bryan Norton

College of Agriculture and Life Sciences Faculty Publications

Management of social-ecological systems takes place amidst complex governance processes and cross-scale institutional arrangements that are mediated through politics of scale. Each management scenario generates distinct cross-scale trade-offs in the distribution of pluralistic values. This study explores the hypothesis that conservation-oriented management scenarios generate higher value for international and national scale social organizations, whereas mixed or more balanced management scenarios generate higher value for local scale social organizations. This hypothesis is explored in the management context of Ruaha National Park (RNP), Tanzania, especially the 2006 expansion of RNP that led to the eviction of many pastoralists and farmers. Five management …

State Of The Climate In 2010, Jessica Blunden, Derek S. Arndt, Molly O. Baringer

United States Department of Commerce: Staff Publications

Several large-scale climate patterns influenced climate conditions and weather patterns across the globe during 2010. The transition from a warm El Niño phase at the beginning of the year to a cool La Niña phase by July contributed to many notable events, ranging from record wetness across much of Australia to historically low Eastern Pacific basin and near-record high North Atlantic basin hurricane activity. The remaining five main hurricane basins experienced below- to well-below-normal tropical cyclone activity. The negative phase of the Arctic Oscillation was a major driver of Northern Hemisphere temperature patterns during 2009/10 winter and again in late …

The topic of this research study was the decision-making process for energy efficiency projects in the U.S. automotive manufacturing industry. Flaws in this decision-making processes are preventing changes that can dramatically reduce energy usage, cost, and pollution. The study was grounded in the theories of energy management, …


A Tale Of Two Carbon Sinks: Can Forest Carbon Management Serve As A Framework To Implement Ocean Iron Fertilization As A Climate Change Treaty Compliance Mechanism?, Randall S. Abate Jan 2011

A Tale Of Two Carbon Sinks: Can Forest Carbon Management Serve As A Framework To Implement Ocean Iron Fertilization As A Climate Change Treaty Compliance Mechanism?, Randall S. Abate

Journal Publications

Any post-Kyoto climate change treaty regime must seek to fully engage the use of carbon sinks to complement emissions reduction measures in order to comply with the treaty's mandates. The Kyoto Protocol did not include avoided deforestation as a mechanism for earning emission reduction credits. However, reducing emissions from deforestation and degradation (REDD) quickly gained popularity as a viable climate change compliance strategy in the period immediately preceding the negotiations at the Fifteenth Conference of the Parties (COP 15) in Copenhagen in 2009. The Copenhagen Accord is replete with references to REDD as a focus for the international community's progression …

An Analysis Of Wind Resources And The Feasibility Of Wind-Energy Generation On The Connecticut College Campus, Michael Marshall Jan 2011

An Analysis Of Wind Resources And The Feasibility Of Wind-Energy Generation On The Connecticut College Campus, Michael Marshall

Physics, Astronomy and Geophysics Honors Papers

A wind-resource analysis was undertaken on the Connecticut College campus to augment the preliminary wind-power feasibility study conducted by Global Energy Concepts (GEC) in 2006. Based largely on modeled wind speeds, this earlier study concluded that wind resources at the college were insufficient to generate large amounts of electrical energy given the small-scale turbine believed to be suited to the campus's available land. In the current wind-resource analysis, rather than using modeled values, on-site wind measurements were made over the course of a year and extrapolated to the hub heights of various turbines. These extrapolations suggest that the mean annual …

Using Renewable Energy Purchases To Achieve Institutional Carbon Goals: A Review Of Current Practices And Considerations, Lori Bird, Jenny Sumner

Publications (E)

With organizations and individuals increasingly interested in accounting for their carbon emissions, greater attention is being placed on how to account for the benefits of various carbon mitigation actions available to consumers and businesses. Generally, organizations can address their own carbon emissions through energy efficiency, fuel switching, on-site renewable energy systems, renewable energy purchased from utilities or in the form of renewable energy certificates (RECs), and carbon offsets. This paper explores the role of green power and carbon offsets in carbon footprinting and the distinctions between the two products. It reviews how leading greenhouse gas (GHG) reporting programs treat green …
