Energy security and climate change are among the top priority challenges for Turkey. High dependency on imported resources jeopardizes the economy, especially with high currency rate and conflicts in neighboring countries from where Turkey imports its energy. Besides, Turkey has already started to experience the impacts of climate change such as increasing temperature along with drought. Floating photovoltaics have proven themselves to be quite efficient in energy production, with evaporation reduction as a positive externality. The purpose of this article is to reveal the possible capacity of floating photovoltaics on constructed water reservoirs of Turkey and draw policy perspectives against existing or anticipated challenges. A total of 4,003 reservoirs were analyzed based on different water surface coverage scenarios. The results of the study proposed 125 TWh electricity generation, slightly above 40% of the nation-wide electricity demand, when 10% of suitable reservoirs were covered. This generation would be highly instrumental in reducing energy dependency and substituting renewables for conventional resource uses. Avoided CO2, thanks to this substitution, was calculated to be 77.1 Mton equivalent. This would obviously be favorable in light of the carbon emission reduction policy of the country and Paris Agreement requirements. Moreover, 1,242.1 hm3 freshwater was assessed to save resources from evaporation loss, which would help to mitigate the climate change pressure on water resources.

Preliminary Study on Site Selection For Floating Hybrid Wind And Solar Energy Systems In Turkey
Yerlikaya, Nevzat Can; Çakan, Çağatay; Başara, Ilgın; Caceoğlu, Eray; Huvaj Sarıhan, Nejan (2021-09-08)
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 ...
A techno-economic feasibility study of a gridconnected hybrid solar pv-wind power generation system in Zimbabwe
Samu, Remember; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2019-1)
The depletion of fossil fuel resources on a worldwide basis and an increase in greenhouse gas emissions and climate change as a whole have caused an urgent search for alternative sustainable energy sources to cater for the rising energy demands. The demand of energy is rapidly growing in both developing and developed nations thus making hybrid renewable energy power systems (RES), comprising Solar Photovoltaic (PV) and wind energy to be chosen as one of the best alternatives. However, on the downside, these...
The role of renewable energy in achieving Turkey's INDC
Arı, İzzet; Yikmaz, Riza Fikret (Elsevier BV, 2019-05-01)
The aim of this study is to analyse impacts of renewable energy sources in achieving Intended Nationally Determined Contribution (INDC) targets of Turkey. INDCs as a part the Paris Agreement are based on national circumstances of countries on climate change. In order to reach the global goal of the Paris Agreement, countries shall monitor, update and upgrade their INDCs. The overall target of Turkish INDC is to reduce its greenhouse gas (GHG) emissions up to 21 per cent from the Business as Usual (BaU) leve...
Transition towards urban system integration and benchmarking of an urban area to accelerate mitigation towards net-zero targets
Kılkış, Şiir (2021-12-01)
Strengthening capacity for cross-sectoral coordination has a crucial role in enabling ambitious climate mitigation. This research work integrates the Sustainable Development of Energy, Water and Environment Systems Index into a policy framework with three main components to compare possibilities for improving urban system performance. Tiers of integration are defined and compared with the index results for more transformative action. The levels range from unintegrated urban sectors and emerging integration,...
Development of a climate risk assessment method for the provinces of Turkiye
Bütün Bayındır, Gülsün Duygu; Yetişkul Şenbil, Emine; Department of City and Regional Planning (2022-8-25)
Climate change is disproportionately threatening vulnerable systems and amplifying existing risks. Considering the increasing impacts of climate change, assessing climate-related risks and identifying respective critical vulnerabilities have gained vital importance in addressing climate change. This thesis aims at examining the climate risk and vulnerability levels of provinces by conducting a climate risk and vulnerability assessment at the national scale provincial level to respond to the immediate climat...
