Energy policy research studies need to consider several objectives since the energy sector is closely related with economy, environmental quality, and supply security. Before 70s, studies were based on a one-way relationship between the energy sector and the economy, and they tried to estimate energy demand given the level of economic activity. However, the Arabic oil embargo, which doubled the energy prices, resulted in an economic crisis since energy is an intermediate good which is used in almost all production activities. These events brought about the consideration of a two-way relationship between the energy sector and economy. Furthermore, most greenhouse gasses (GHG) that cause global warming are emitted by energy generation or consumption activities. Consequently, the level of energy generation and resource types used directly affect the level of GHG emissions. Another point to consider on energy studies is the security of energy resources. During the Arab oil embargo, countries that import oil from Arabic countries were stranded. Therefore, whether to supply energy resources domestically or not is another important question. Above-mentioned concerns point out the requirement of a multi objective decision support system that combines engineering and economics perspectives. The main purpose of this study is the development of such a decision support system. For this purpose, the impact of GHG emissions and foreign energy dependence restrictions on economic welfare is investigated by using a mathematical model that represents economy and energy sector together. This is accomplished by integrating a one-sector neoclassic growth framework with a detailed activity analysis model representing energy sector and environmental consequences. Then, level of economic welfare corresponding to different level of emissions and energy dependence is evaluated and relationship between these objectives is presented. In addition to relationship between objectives, reaction of economy and energy sector to the restrictions is investigated so that how a country meets specific goals is presented. Literature studying energy and environmental policy analysis is based on quantification of economic burden resulting from commitment to certain international agreements such as the Kyoto protocol. On the other hand, this study explores the level of economic burden and change in energy sector for different levels of emission and foreign energy dependence restrictions. Moreover, robust policies against world energy price shocks are searched for. This knowledge is expected to help decision makers to make informed strategic decisions.

A review of Ghana's energy sector national energy statistics and policy framework Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2016-01-01) In this study, a review of Ghana's energy sector national energy statistics and policy framework is done to create awareness of the strategic planning and energy policies of Ghana's energy sector that will serve as an informative tool for both local and foreign investors, help in national decision-making for the efficient development and utilization of energy resources. The review of Ghana's energy sector policy is to answer the question, what has been done so far? And what is the way forward? The future re...
BIM based Multi Objective Building Life Cycle Energy Performance Evaluation Using Particle Swarm Optimization Altun, Murat; Akçamete Güngör, Aslı (2015-11-02) Building energy performance evaluation is a multi-objective problem that plays crucial role in reducing environmental effects and energy costs, especially for energy importing countries to minimize its adverse effect on politics and economy. Moreover, two-fifth of world energy consumption and thirty percent of CO2 emission belong to buildings and services. Building energy performance is estimated by steady state and dynamic energy calculation methods whereas dynamic simulation performs more accurate results...
Solar energy potentials in strategically located cities in Nigeria: Review, resource assessment and PV system design Okoye, Chiemeka Onyeka; Taylan, Onur; Baker, Derek Keıth (2016-03-01) Ensuring energy security increasingly requires expanding both yield and resilience of supply through source diversification. In this study, the current energy situation of Nigeria is presented through a detailed literature review. The survey reveals that access to the national grid is limited, and the power delivered to areas classified as urban with grid connection is very unreliable. An initial assessment of the potential utilization of solar based technologies for electricity generation is presented for ...
Resource efficient and cleaner production in selected foundries through environmental performance evaluation Usta Benli, Ayça; Demirer, Göksel Niyazi; Department of Environmental Engineering (2017) The main objective of this study was to develop Resource Efficient and Cleaner Production (RECP) measures for the ferrous foundry sector. For this purpose, environmental performance evaluation and benchmarking studies were conducted in six ferrous foundries. The environmental performance was calculated by using environmental performance indicators of specific energy and water use, metal yield and sand regeneration ratio. The gap between the benchmarks and actual performances revealed the improvement potenti...
Assessment of the role of nuclear power on energy policies and climate change mitigation strategies of developing countries Güngör, Görkem.; Sarı, Ramazan; Department of Earth System Science (2020) Nuclear energy is considered as one of the climate change mitigation options in the energy supply sector by substituting electricity generated from base load fossil fueled power plants reducing GHG emissions. Internalizing the costs of CO2 emissions provides an additional economic incentive for investment in nuclear energy both in developed and developing countries. While developed countries with stable energy demand are focused on the robustness and resilience of their energy systems, the priority of devel...
