Electricity generation cost and environmental effects of electricity generation continue to be among central themes in energy planning. The choice of electricity generation technology and energy source affect the environment through released greenhouse gases and other waste. United States is the worlds second-largest CO2 emitter and electricity consumer. This thesis aims to estimate the optimal capacity expansion of electric power sector in the United States for 2022-2050. We develop a fuzzy multi-objective linear program to minimize cost and environmental effects. In sensitivity analyses, we show how different policies and price evolution may alter the mix. Later on, we examine the effects of the new capacity mix and implied generation on the cost of electricity and emissions. We find that direct modeling of capacity factors give meaningful results. According to this thesis, renewable energy is expected to reach more than 1100 GW installed capacity by 2050. This reduces average cost of electricity generation by more than 70 percent and reduces CO2 emissions by more than 80 percent compared to expected end-2021 levels.

Overcoming problems in Turkey's renewable energy policy: How can EU contribute? Sirin, Selahattin Murat; Ege, Aylin (2012-09-01) Fossil fuels cover most of the energy demand in the world, and this creates significant social, economic and environmental problems. Many countries have taken measures to increase the share of renewable energy sources (RES), especially in electricity generation, and the review of literature shows that the success of a country in RES diffusion depends on a comprehensive renewable energy policy which combines political commitment with stable and long-term support measures that stimulate technological innovati...
Performance analysis of a solar chimney power plant for rural areas in Nigeria Okoye, Chiemeka Onyeka; Taylan, Onur (2017-04-01) Diverse renewable energy technologies are urgently needed, especially for developing countries. This paper aims to create awareness of solar chimney power plants (SCPP) as a viable and sustainable alternative in rural communities with limited or no access to the grid. The study considers site-specific hourly meteorological data in assessing the feasibility of SCPP in seven selected regions in Nigeria. A theoretical model was established for power output, levelized cost of electricity (LCOE) and avoided carb...
Transformation pathways toward a sustainable energy system in Turkey Fathurrahman, Fahman.; Soytaş, Uğur; Department of Earth System Science (2019) The important factors for designing and implementing a sustainable energy system consist of a sufficient, affordable, secure, and environmentally sound energy supply along with the efficient use of energy. Given its high dependency on foreign energy resources, the current energy system in Turkey is far from satisfying the criteria of a sustainable energy system. In addition, relying solely on fossil fuels is no longer a proper alternative mainly due to its impact on climate change and vastly diminishing res...
Optimal sizing of stand-alone photovoltaic systems in residential buildings Okoye, Chiemeka Onyeka; Solyali, Oguz (2017-05-01) Solar photovoltaic (PV) system is one of the matured solar-to-electricity conversion technologies with a great potential for residential applications. For wider adoption of PV systems, there is a need for an accurate sizing and economic assessment tool to inform decision makers. In this study, we propose a new optimization model based on integer programming for the adoption of stand-alone PV systems in the residential sector. The proposed model not only determines the optimal number of PV modules and batter...
Assessment of renewable energy based micro-grids for small communities Sadati, S.M. Sajed; Taylan, Onur; Sustainable Environment and Energy Systems (2016-7) Deploying renewable energy systems to supply electricity faces many challenges related to cost and variability of the renewable resources. One possible solution to these challenges is to hybridize renewable energy systems with conventional power systems and include energy storage systems. In this study, the feasibility analysis of two cases for electricity generation systems as (i) photovoltaic (PV)-battery-pumped hydro system (PHS) and (ii) PV-wind-battery are presented as a Renewable Energy Micro-Gr...
