Improving The Energy Efficiency Of Dehumidification Technology At A Large Facility In Florida, Brandon Willson Hoilett Dec 2013

Improving The Energy Efficiency Of Dehumidification Technology At A Large Facility In Florida, Brandon Willson Hoilett

Masters Theses, 2010-2019

This thesis examines energy use and management of twenty heat pipes used in dehumidification systems at a large (10,000+ acre) facility in Florida. Eleven of the twenty heat pipes use electric strip heaters that, when activated, consume 693.8 kW of electrical power from the grid. Solar photovoltaics, specifically a silicon monocrystalline cell with 22.5% efficiency, were considered as a means to provide an alternative energy source and opportunity for cost savings for 11 of the heat pipes (Sunpower, 2011). The remaining nine heat pipes use hot water heaters for which alternative energy sources were not considered. Data gathered and analyzed …

Economic Challenges Facing Kentucky’S Electricity Generation Under Greenhouse Gas Constraints, Energy And Environment Cabinet, Commonwealth Of Kentucky, Department Of Statistics, University Of Kentucky, Center For Applied Energy Research, University Of Kentucky, Pacific Northwest National Laboratory

Statistics Reports

From the preface:

For the Energy and Environment Cabinet (EEC), which has primacy in administering most federal environmental laws and regulations at the state level, we have to understand the implications of what is arguably one of the most challenging issues to confront us—greenhouse gas (GHG) emissions and their impact on climate change. Efforts to reduce GHG or carbon dioxide (CO2) emissions have moved beyond the point of discussion at the national level, and the United States Supreme Court has ruled that the U.S. Environmental Protection Agency (EPA) has the authority to regulate GHG emissions. Furthermore, while public …


A Case Study Of Zero Energy Home Built For Solar Decathlon Competition 2013, Sanjib Mulepati Dec 2013

A Case Study Of Zero Energy Home Built For Solar Decathlon Competition 2013, Sanjib Mulepati

UNLV Theses, Dissertations, Professional Papers, and Capstones

Energy consumption in residential homes has been a subject of research related to sustainability. Reduction in the consumption of energy is a goal of sustainable construction. The Department of Energy (DOE) started a Solar Decathlon competition in 2002 in which the students from different universities around the globe build an energy efficient and affordable home suitable for their climate and location. The main goal of this competition is to select the best home that is designed and built in a sustainable way. In this study, the home designed and constructed for participation in the competition by the students at University …

Solar Cell Temperature Dependent Efficiency And Very High Temperature Efficiency Limits, John Robert Wilcox Oct 2013

Solar Cell Temperature Dependent Efficiency And Very High Temperature Efficiency Limits, John Robert Wilcox

Open Access Dissertations

Clean renewable solar energy is and will continue to be a critically important source of electrical energy. Solar energy has the potential of meeting all of the world's energy needs, and has seen substantial growth in recent years. Solar cells can convert sun light directly into electrical energy, and much progress has been made in making them less expensive and more efficient. Solar cells are often characterized and modeled at 25 °C, which is significantly lower than their peak operating temperature. In some thermal concentrating systems, solar cells operate above 300 °C. Since increasing the temperature drastically affects the terminal …

Role Of Natural Gas In America's Energy Future: Focus On Transportation, Dharik Mallapragada, Rakesh Agrawal Jun 2013

Role Of Natural Gas In America's Energy Future: Focus On Transportation, Dharik Mallapragada, Rakesh Agrawal

Purdue Policy Research Institute (PPRI) Policy Briefs

The energy landscape of the United States for the past century has been dominated by the use of fossil fuels namely coal, petroleum, and natural gas (NG). While coal usage was dominant during the early 1900’s, petroleum has been dominant ever since the second half of the 20th century owing to increasing use of liquid fuels, gasoline and diesel, for transportation. In contrast, NG consumption in the U.S., currently at ~25% of total primary energy use, has only been steadily increasing since the early 1990’s (BP, 2012). However, the last decade has seen rapid growth in U.S. NG consumption …


Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Christof Steckel, Robert J. Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer Jun 2013

Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Christof Steckel, Robert J. Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer

Physics Faculty Publications

We analyze the relationship between economic development and energy consumption in the context of greenhouse gas mitigation. The main contribution of this work is to compare estimates of energy thresholds in the form of minimum energy requirements to reach high levels of development with output projections of per capita final energy supply from a group of integrated assessment models (IAMs). Scenarios project that reductions of carbon emissions in developing countries will be achieved not only by means of decreasing the carbon intensity, but also by making a significant break with the historically observed relationship between energy use and economic growth. …


A Cross-Country Analysis Of Energy Efficient Development, Nicholas Fleagle Jun 2013

A Cross-Country Analysis Of Energy Efficient Development, Nicholas Fleagle

Honors Theses

Maximizing energy efficiency, producing as much as possible with as little energy as possible, is something every country should be working toward. This study measures the efficiency of specific countries by examining the interrelationships that exist among each country’s energy consumption and such measures of development as health, education, income, access to essentials and CO2 emissions. It then analyses why certain countries are more efficient than others and how these inefficient countries can improve. Data Envelopment Analysis (DEA) is used to generate a cross country comparison of energy efficiency scores over multiple dimensions of development. Pairs of inefficient countries and …

Energy Independence In The Usa, Janice Ringler May 2013

Energy Independence In The Usa, Janice Ringler

Student Papers in Public Policy

During President Barack Obama’s first term and throughout the recent presidential campaign, there was much discussion about becoming energy-independent as a nation. Indeed, one of the most pressing issues facing the country today is our energy future. This is especially a concern in areas where mainstream energy sources (coal, gas, oil) do not exist, and thus must be imported. Many believe that this is a problem that communities and states are better suited to tackle than the federal government due to the flexibility and knowledge of state policy initiatives. In this brief I will propose a variety of measures that …
