Chemical And Physical Characteristics Of Rivers Above And Below Four Hydroelectric Power Facilities In The Chiriquí Viejo And Chico Watersheds Of Chiriquí, Panama, Tricia Light

Independent Study Project (ISP) Collection

The advance of anthropogenic climate change and human energy use has sparked unprecedented international interest and investment in fossil fuel free energy sources such as hydroelectric power. Extensive construction of hydroelectric power facilities has occurred in Panama in recent years, particularly in the westernmost Chiriquí province. Hydroelectric power, especially that generated by relatively small facilities, is generally thought to be a “clean” alternative energy source with few negative environmental consequences. Some evidence suggests, however, that even small facilities can have significant ecological impacts on rivers. This study investigated river properties above and below four small hydroelectric facilities on the Chiriquí …

One Year Later: The Politics And Stories Of Post-Earthquake Nepal, Boyer Andrew

Independent Study Project (ISP) Collection

A 7.8 magnitude earthquake struck Nepal on April 25^th, 2015. This was followed by a second major earthquake of magnitude 7.3 on May 12^th , 2015. These disasters took the lives of thousands of Nepali people, destroyed hundreds of thousands of structures, and displaced an estimated two million people. Immediately following the disaster, there was an outpouring of humanitarian aid from around the world. This lead to a conference where $4.1 billion USD of reconstruction funds were pledged to Nepal by international donors. Five months later, a new constitution passed into law and an informal blockade of …

Fracking In Pennsylvania: A Spatial Analysis Of Impacts On Land Cover And Land Use, The Viewshed, And The Audioshed, Kelly A. Collins

Student Publications

Hydraulic fracturing is the process of extracting natural gas from layers of shale rock beneath the surface of the Earth. The largest source of natural gas in the US is the Marcellus Shale, largely located in Pennsylvania, and it is believed to hold about 141 trillion cubic feet of natural gas in its shale deposits. My study examined the impacts of well sites on land cover and land use, the viewshed, and the audioshed. To study the effect of wellpads on land use and land cover, we overlaid a layer of wellpads over land cover data as well as a …

The Effects Of Using Natural Gas In Light-Duty Vehicle Fleet Of The United States On Its Energy Dependency And Greenhouse Gas Emissions, Nurullah Ayyilmaz

Graduate Program in International Studies Theses & Dissertations

Shale boom has changed the track of discussions on the future of the U.S. energy politics. A new opportunity emerged to meet domestic demand of the U.S. by using secure sources. Transportation accounts for a quarter of energy consumption in the U.S. Increasing the share of natural gas in the transport sector bolsters the U.S. energy security because of shifting from insecure sources (imported oil) to secure sources (shale gas reserves). Using natural gas instead of oil in light-duty vehicles (LDVs) contributes to the efforts of decreasing dependence on insecure sources and also decreases anthropogenic greenhouse gas (GHG) emissions caused …

Conversion Of Landfill Gas To Liquid Hydrocarbon Fuels: Design And Feasibility Study, Ryan Alexander Kent

USF Tampa Graduate Theses and Dissertations

This paper will discuss the conversion of gas produced from biomass into liquid fuel through the combination of naturally occurring processes, which occur in landfills and anaerobic digesters, and a gas-to-liquids (GTL) facility. Landfills and anaerobic digesters produce gases (LFG) that can be converted into syngas via a Tri-reforming process and then synthesized into man-made hydrocarbon mixtures using Fischer-Tropsch synthesis. Further processing allows for the separation into liquid hydrocarbon fuels such as diesel and gasoline, as well as other middle distillate fuels. Conversion of landfill gas into liquid fuels increases their energy density, ease of storage, and open market potential …

Environmental Variables Affecting The Performance Of Large-Scale Solar Photovoltaic Power Plants, Parikhit Sinha

Climate Sustainability Lecture Series

The environmental sciences have been critical to identifying global environmental challenges such as climate change, but they have been less extensively utilized in deploying solutions to those challenges, such as solar energy. Environmental variables such as temperature, humidity, aerosols, clouds, soiling, and snowfall have important effects on solar PV performance, and these effects can vary regionally. The current status of large-scale solar PV deployment will be discussed along with the role of environmental variables on PV performance.

Powering The Planet: The Role Chemistry Plays In Solar Energy Technology, Amy M. Scott

Climate Sustainability Lecture Series

Global energy demands are projected to double by 2050, according to the U.S. Department of Energy, and solar energy has the greatest potential as the most benign, universal resource for generating electricity. However, harnessing the solar energy efficiently and converting it towards useful forms of power that are compatible with our current infrastructure remains an elusive goal. Today’s solar energy utilization relies on silicon-based photovoltaic (PV) technology, which converts photon energy to electrical energy. The efficiency of these devices remains low (< 30%) and the cost of processing silicon and installing solar panels in homes makes PV uneconomical compared to the current price of electricity. Research efforts towards developing new inorganic and organic materials for thin film PV to replace silicon are currently underway. Organic materials are particularly interesting from the standpoint of developing simple, cheap materials that can be easily tailored for future PV devices. The future of solar energy utilization relies on developing solar paints for vehicles, solar shingles for rooftops, and spray-on solar ink for small device applications, but continued fundamental research is needed for decreasing cost and improving efficiency for next generation devices.

Production Of Biodiesel From Soybean Oil Using Supercritical Methanol, Shriyash Rajendra Deshpande

USF Tampa Graduate Theses and Dissertations

The slow yet steady expansion of the global economies, has led to an increased demand for energy and fuel, which would eventually lead to shortage of fossil fuel resources in the near future. Consequently, researchers have been investigating other fuels like biodiesel. Biodiesel refers to the monoalkyl esters which can be derived from a wide range of sources like vegetable oils, animal fats, algae lipids and waste greases. Currently, biodiesel is largely produced by the conventional route, using an acid, a base or an enzyme catalyst. Drawbacks associated with this route result in higher production costs and longer processing times. …

Application Of Recycled Media And Algae-Based Anaerobic Digestate In Scenedesmus Cultivation, Xinyi E, Czarena Crofcheck, Mark Crocker

Biosystems and Agricultural Engineering Faculty Publications

To make large-algae cultivation systems sustainable, commercial fertilizer inputs should be minimized. One means of achieving this is to maximize the recycle of nutrients used in algae cultivation. In addition to recycling nutrient-containing water from algae harvesting and dewatering, after harvesting algal biomass can be used as a substrate for anaerobic digestion, which can then generate mineralized nutrients to be used for further cultivation. In this study, the effect of recycling media and using mineralized nutrients during Scenedesmus cultivation was investigated. The recycled media proved to be able to support cell growth with nutrient replenishment, and it could be recycled …

Brief 12: Energy Transitions To Modern Renewables: Context, Barriers, And Promises, Stanislav Vavilov

Governance and Sustainability Issue Brief Series

The world is not running out of fossil fuels, as is often claimed. With technological progress and favorable economic conditions, a process of resource-base expansion occurs through the production of resources that were previously considered economically unviable. Resource-base expansion requires increasing capital investments per unit of energy extracted and an accompanying rise in production costs per unit. The world is running out of cheap fossil fuels, and in the long term, dependence on fossil fuels leads to energy services that are much more expensive and inaccessible. Given other important incentives for transitioning from fossil fuels, such as the need to …

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric …

The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler

Journal of Environmental and Resource Economics at Colby

This paper seeks to address the effect of “Spare the Air” pollution control alerts in the San Francisco Bay Area in California on the use of Bay Area BikeShare as a form of transportation. By observing the daily alerts on the duration of rides using BikeShare, this paper observes if STA ozone alerts are effective in changing human behavior. The results show that only as a subscriber to the BikeShare program and on an alert day does duration decrease whereas customers regardless of if it is an alert day will ride more often and at longer distances. The results contradict …

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.

Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda

Journal of Environmental and Resource Economics at Colby

This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.

Media Effects On Solar Panel Installations Across 20 States, Casey Romeo

Journal of Environmental and Resource Economics at Colby

This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic …

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.
