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 developing countries continues to be the strengthening of energy security in order to supply their increasing energy demand. Climate change is one of the major global commons problems of our society which requires long-term and ambitious strategies in order to transform the socioeconomic development to low-carbon energy pathways. The role of nuclear energy in transformation of the energy sector has been assessed by the climate change community on regional and global scales using various integrated assessment models. However there is a gap between the results of these studies and the quantitative commitments of countries for climate change mitigation in their NDCs submitted to the UNFCCC resulting in higher GHG emissions. In this study I show that the role of low-carbon energy supply options for climate change v mitigation depends on global socioeconomic development pathways especially for developing countries already facing a transition in their economies and energy systems. The role of nuclear energy for supplying the electricity required for developing countries is dependent on global socio-economic pathways supporting investment in most stringent GHG emissions scenarios. Expert elicitation was used for MCA of energy supply system modeling results by integrating CO2 emissions from power sector, flexibility of the electricity grid to supply peak load demand, change in welfare from carbon tax and transfer of revenues for subsidizing renewable energy, and the total discounted energy system costs. The results show that for the second commitment period of the Paris Agreement, the role of nuclear energy is for supporting the transition of the energy system to a low carbon future for both green transformation and regional rivalry scenarios.

GIS-based site selection methodology for hybrid renewable energy systems: A case study from western Turkey
Aydin, Nazli Yonca; Kentel Erdoğan, Elçin; Duzgun, H. Sebnem (Elsevier BV, 2013-06-01)
Renewable energy sources are presently being considered as alternatives to fossil fuels, because they are perpetual, environmentally friendly, and release negligible amounts of greenhouse gases to the atmosphere while producing energy. A disadvantage of renewable energy systems, however, is that continuous energy generation is not possible by using only one type of renewable energy system, since renewable energy resources depend on climate and weather conditions. Two or more renewable energy systems can be ...
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...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
Preliminary Study on Site Selection For Floating Hybrid Wind And Solar Energy Systems In Turkey

It is well-known that even though fossil fuels are the main energy resource in Turkey, use of sustainable energy resources such as wind and solar energy has been increasing in the past years and expected to continue on this trend in the next years to come. The suitable land for land-based wind turbines and photovoltaic (PV) systems could also be convenient for various other purposes, such as agriculture. This study aims to investigate the suitable sites for a combined floating wind and solar systems in the ...
Multi-criteria decision making in site selection for nuclear power plants
Tuncer, Berna; Dener Akkaya, Ayşen.; Department of Statistics (2019)
Nuclear energy is an important alternative energy source. However the construction of nuclear power plants (NPP) requires the consideration of various factors, such as environmental, economic, socioeconomic, health and safety. Accordingly, selection of the most suitable site for the construction of a nuclear power plant yields to a multi-criteria decision making problem. Seismic hazard, environmental conditions, population, health hazards, availability of water resources (for cooling purposes) are among the...
