With increasing population and developing regulations, wastewater treatment plants (WWTP) have started to become a higher energy consuming sector in order to serve higher capacities. In the design and management phases of a treatment plant, energy consumption and carbon footprint of the plant should be considered. In this regard, hypothetical and real case models are created to simulate and compare WWTP systems. In this thesis study, first, municipal WWTPs of Turkey were analyzed to determine the traditional technologies concerning biological treatment and sludge stabilization of municipal wastewaters. Combinations of different units and processes were used to build 105 hypothetical WWTP models. These models were then used to determine sludge production amount, energy consumption, and carbon footprint. It was observed that specific energy consumption ranged between 0.002 kWh/m3 and 0.89 kWh/m3, while, carbon footprints varied between 588 kgCO2eq/h and 5,697 kgCO2eq/h. In addition, Bursa East Domestic WWTP was considered for the simulation-based optimization of a real WWTP. It was shown that both energy consumption and carbon footprint of this treatment plant can be reduced by 10%.

Investment needs for climate change adaptation measures of electricity power plants in the EU
Lise, Wietze; van der Laan, Jeroen (2015-10-01)
Climate change is expected to have impacts on the power sector, leading to, among others, a need for adaptation measures in the sector in the near future. This paper analyses the need to adapt to climate change impacts for power generation technologies in Europe until 2100. Europe is broadly divided into four geographic climate zones, for which regional climate change impacts are quantified with the help of the ENSEMBLES RT2b data. The European future technology mix is based on two Eurelectric energy scenar...
Operating policies for energy generation and revenue management in single-reservoir hydropower systems
Ak, Mumtaz; Kentel Erdoğan, Elçin; Savaşaneril Tüfekci, Seçil (Elsevier BV, 2017-10-01)
We study the reservoir management problem in hydropower plants, and propose operating policies to maximize the average annual energy generation or the average annual revenue. Under revenue maximization, our policies allow for short-term electricity price variations to be incorporated into the long-term plan. First, we provide a detailed review of hydropower plant operation, focusing on implicit stochastic optimization approaches and integration of energy price variations in reservoir management. Then, we ex...
Life cycle assessment of two different renewable energy systems for a selected region: Bozcaada island
Şentürk, Ayşe Eylül; Oğuz, Elif (2020-01-01)
Energy production without destroying the environment has been one of the most crucial issues for the people living in today'sworld. In order to analyse whole environmental impacts of energy production process, life cycle assessment (LCA) is widely used. In this study, two distinct renewable energy systems are assessed. First, a land-based wind farm which has been operating in Bozcaada Island since 2000 compared with a proposed solar photovoltaic power plant in terms of Energy Pay-Back Time (EPBT) periods an...
Energy consumption and income in G-7 countries
Soytaş, Uğur; Sarı, Ramazan (2006-10-01)
Several industrialized countries have signed the Kyoto Protocol, promising to reduce greenhouse gasses (GHG) emissions. To reduce or mitigate such emissions several policies including reducing energy consumption, increasing energy efficiency, decreasing energy intensity and forestation may be possible. The viability and effectiveness of each policy may differ due to country specific factors. This paper tries to assess the impact of a change in energy consumption on income and vice versa in G-7 countries. We...
Literature review on BIM-based building energy performance optimization
Can, Esra; Akçamete Güngör, Aslı (İstanbul Teknik Üniversitesi; 2020-11-14)
Buildings comprise a large part of global energy consumption and make a significant contribution to overall CO2 emissions in the world. Therefore, increasing the energy efficiency of buildings becomes a priority to reduce these undesirable effects. Building energy performance assessments are complex multi-criteria problems as the energy performance is affected by many factors such as building orientation, envelope design, climate conditions, daylighting levels, and HVAC system usage schedules. This complica...
