Global warming and climate change problem can be solved by only decreasing greenhouse gases (GHGs). About 26% of the global GHG emissions are emitted by the transportation sector. Switching from fossil fuel burning vehicles to electric vehicles is one of the most promising solutions. However, 68% of the electricity is generated by using fossil fuels in the world and if a switch to electric vehicles happens without transforming the electricity generation sector, transportation emissions might even increase. Therefore, EVs are only as clean as their energy source. Implementing renewable energy into transportation sector is a crucial step that must be taken to reduce transportation emissions. Wind energy resources have larger spatial and temporal variations compared to solar energy. In addition, solar energy is much easier to estimate and imply. PV plants can be installed in a decentralized way. Thus, every parking lot can be covered with PV. In this study, a general model is developed to estimate the energy generation from PV-covered parking lot systems and energy demand for electric cars. After the model is developed, case studies are performed using temperature and drive cycle information for Istanbul, Los Angeles and New York City. These locations are compared in terms of PV-EV feasibility considering several aspects. On the energy demand side, the effects of ambient temperature and driving style are considered to have a more accurate model. The results show that PV system can cover the annual demand for all case studies. The annual energy demand of 10 cars in Istanbul case study is about 300 MWh while the energy generation from the modeled 22.5 kW PV system is about 306 MWh. In the comparison of two cities, Los Angeles which represents mild ambient conditions is more favorable than New York City which represents the ambient conditions which include cold winters and hot summers. The results reveal that the ambient and driving conditions can increase the energy demand by 50%. As a result, PV-EV systems decreases the stress on the grid due to EV charging. Scheduled charging can increase the benefit even more.

Experimental and numerical investigation of carbon sequestration in saline aquifers
Izgec, O.; Demiral, B.; Bertin, H.; Akın, Serhat (null; 2005-07-28)
Because of the global warming threat posed by greenhouse gases, mainly by CO2, some strategies were proposed. Along those, disposal and long term storage, of greenhouse gases is important for reducing global warming. Aquifers represent the most widely available and the second largest, naturally occurring potential store for CO2. Although there are a number of mathematical modeling studies related to injection of CO2 in deep saline aquifers, experimental studies are limited and most studies focus to sandston...
Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey
Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01)
Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...
Impact of Urban Street Network on BIPV Generation Capacity of Buildings
Duran, Ayca; Akgül, Çağla; Gürsel Dino, İpek (2022-10-11)
Climate change necessitates a critical reconsideration of the built environment since buildings are among the top fossil fuel consumers. Solar energy generation through building integrated photovoltaic (BIPV) systems is one of the most common onsite energy generation methods. However, many factors regarding urban morphology can negatively affect BIPV generation. Urban block typologies and spatial patterns are commonly studied descriptive metrics of an urban morphology that affect the solar energy potential....
Greenhouse effect reduction by recovering energy from waste landfills in Pakistan
Zuberi, M. Jibran S.; Ali, Shazia F. (2015-04-01)
Landfills all around the world are one of the major sources that contribute towards global warming and climate change. Although landfilling should be prioritized last in the waste management hierarchy due to highest greenhouse gas emissions as compared to other waste management systems it is still very common around the world. In this study, methane emissions are estimated by applying First Order Decay model to landfills in Pakistan over the latest data available by Pakistan Environmental Protection Agency....
Potential impacts of climate change on wind energy resources in Türkiye
Işık Çetin, İrem; Yücel, İsmail; Arı, İzzet; Department of Earth System Science (2023-3-02)
Increasing the use of renewable energy is crucial in reducing the adverse effects of climate change. However, climate change will also affect weather-dependent renewable energy resources. Therefore, this study aims to identify the effects of climate change on the wind energy resources in Türkiye, which is in the Mediterranean hotspot, in the next century by using recent climate projections (CMIP6) with two different scenarios. The study includes four different results for wind resources in Türkiye. First, t...
