Applications Of Cultural Theory And Empirical Analysis Of Sustainable Energy Policy Preferences In Arkansas, John Henry Kester Iii Dec 2015

Applications Of Cultural Theory And Empirical Analysis Of Sustainable Energy Policy Preferences In Arkansas, John Henry Kester Iii

Graduate Theses and Dissertations

The local policy arena is ripe for research on policy elite decisionmaking because where policy diffusion is concerned, previous studies focus on state-to-state and city-to-city dynamics. Therefore, there is a significant opportunity to expand understanding about the adoption of policies and policy diffusion at the local level. Identification of individual level determinants that signify policy adoption is a cornerstone to fostering this knowledge. This study examines such preference indicators found among policy elites in select Arkansas cities. For this research, the primary theoretical perspective for evaluating individual determinants is cultural theory, which has shown strong correlation to individual policy preference …

The Adequacy Of Programs In Nsw In Supporting Vulnerable Households To Transition To Renewable Energy, Madison Dell Apr 2015

The Adequacy Of Programs In Nsw In Supporting Vulnerable Households To Transition To Renewable Energy, Madison Dell

Independent Study Project (ISP) Collection

Rising electricity prices in Australia have caused low-income households to take drastic measures to reduce their energy consumption, cutting back on essential needs like food and heating. At the same time, prices for renewable energies like solar PV are decreasing, making renewable energy a more viable option for low-income households than grid electricity. In support of increasing the nation’s supply of renewable energy, the New South Wales government is funding the Zero Net Energy Town (Z-NET) project. The Z-NET project is a new initiative to create Australia’s first town that supplies all of its energy through renewable energy sources, using …

Innovative Procurement Models For Renewable Electricity, Anthony Amato Jan 2015

Innovative Procurement Models For Renewable Electricity, Anthony Amato

NECSC Conference 2015

Colleges and universities are committing to aggressive emission reduction goals as part of their efforts to reduce their carbon footprints and meet their commitments under the ACUPCC. Electricity use commonly accounts for 40 percent of a higher education institution’s emissions, and as such the purchase of renewable electricity is a common and effective means of reducing indirect (scope 2) emissions and achieving sustainability goals. To date, the vast majority of college and universities purchasing renewable electricity have been through short-term contracts (1 – 3 years) for utility products or renewable energy certificates (RECs). Only recently have a few leading institutions …

Energy Economy In Regulated And Market-Based Power System: Case Study In Serbia, Mileta Zarkovic, Ivan Skokljev

Turkish Journal of Electrical Engineering and Computer Sciences

This study presents a possible process of simulating power plant generation planning. The process combines expected overall industry costs, associated cost uncertainty, and expected CO$_{2}$ emissions for different generations, variations of future fossil fuel costs, carbon prices, plant investment costs, and demand, including price elasticity impacts. Uncertainty in the decision stems from the elasticity of prices of fuel and electricity. The aim of this paper is to apply fuzzy numbers to power generation planning and to use a Monte Carlo simulation to check. Simulations are demonstrated through a case study of an electricity industry with coal and lignite, combined cycle …
