This question is derived from Environmental, Social and Economic Development topic.
Sustainable development is a concept that intersects with the environment, encompassing three key dimensions: environmental, social, and economic variables.

Energy demand encompasses the dynamics between the price and quantity of energy, specifically in the form of fuel or electrical power

Energy intensity is just the opposite of energy efficiency; however, many additional factors might contribute to a shift in energy intensity. The energy intensity is influenced by both the energy efficiency at the firm level and the mix of industries (Schwarz, 2017). The formulation of energy intensity can be expressed as follows: Energy intensity = Energy input /Energy output

Elastic energy demand is observed when the % change in the quantity of energy demanded surpasses the % change in energy price.

Non-renewable energy resources encompass coal, natural gas, and oil. Coal undergoes a supply chain that begins with exploration and continues through various stages, including mining, washing, transport, processing, transformation, and consumption. The primary actors in the coal supply chain are the companies supplying the coal, the coal companies, the logistical service providers, and the end consumers (Man-zhi et al., 2009). Nevertheless, there are several adverse environmental effects that occur simultaneously, particularly during the power generation process. For instance, the mining and processing of coal can have negative effects on landforms, water quality, air quality, and other environmental factors (Wang et al., 2021).

Natural gas is commonly regarded as the fossil fuel with the lowest carbon content.

The renewable energy supply chain can be described as the process of converting raw energy into usable energy, encompassing a well-structured framework of management principles that govern the procurement of energy resources and the subsequent consumption of usable energy. The process primarily comprises five distinct stages, namely supply, production, transmission, distribution, and demand. These stages encompass the entire renewable energy supply chain, from sourcing raw materials to delivering the end product (Luthra et al., 2015)

Geothermal energy is considered a sustainable energy source due to its lack of harmful emissions. Additionally, in many geothermal sites, the waste generated from extracting heat is safely disposed of by being returned to the subsurface (Yadav et al., 2022). In addition to the direct utilization of heat resources, similar to other renewable energy sources, the conversion of heat energy into another form of energy is necessary for its application in industrial and agricultural contexts. Heat-pump systems have the capability to store geothermal energy, enabling the management of fluctuations in demand between low and high peaks. Nevertheless, the utilization of geothermal energy is limited to specific geographical areas in order to maximize its efficiency potential. The process of collecting and converting necessitates significant financial and technological investments (Wee et al., 2012).

The social and economic aspects of sustainable development can be measured with a variety of energy indicators. In terms of the social dimension, the most important indicators are availability, affordability, inequality, and security.

Variable costs for energy encompass expenditures related to fuel, operational and maintenance activities, and potential charges associated with CO2 emissions.

Green banks and green bonds possess considerable promise for facilitating the advancement of sustainable energy initiatives. Green banks possess several advantages. Firstly, they provide improved credit conditions for clean energy projects. Secondly, they have the capability to combine numerous small projects to attain a commercially appealing scale. Additionally, green banks contribute to the development of innovative financial products. Lastly, they contribute to the expansion of the market by disseminating information regarding the advantages associated with clean energy initiatives (Sachs et al., 2019).

This question is derived from Global Oil Supply topic.
Several factors influence the global oil supply. The main one is the production capacity of countries and companies, which includes both traditional and new sources such as shale oil. Advances in technology and investment also help increase the supply (Mohaddes and Raissi, 2018). Political and geographical factors can also affect the supply of oil. For example, political stability and conflicts can disrupt production, whereas the location of oil reserves plays a role in how much can be produced. Market conditions such as the price of oil can either encourage or discourage production. Higher prices make it profitable to produce more, even from difficult sources, whereas lower prices can lead to production cuts. The idea of “peak oil” is also relevant. This is when the world reaches its highest level of oil production before it starts to decline. Opinions differ on whether we have reached this point, but some believe that new technologies and discoveries could delay this decline. Finally, the move towards renewable energy affects the oil supply. Efforts to lower greenhouse gas emissions have led to a focus on alternative energy sources, which could reduce the long-term need for oil and change the global oil supply dynamics.

Solar energy, wind energy, various forms of water-based energies (hydro, wave, tidal, ocean, and current energy), biomass energy, and geothermal energy are the most basic renewable and sustainable renewable energy sources.
The answer is B.

A renewable energy source is described as the capacity to refresh itself at a proportion equivalent to the energy retrieved from the source and faster than the source’s consuming ratio. solar energy, wind energy, various forms of water-based energies (hydro, wave, tidal, ocean, and current energy), biomass energy, and geothermal energy are the most basic renewable and sustainable renewable energy sources. Technological advances, increasing environmental pollution, and rapid fossil fuel consumption mean the demand for and interest in renewable energy sources is rissing.
The answer is C.

According to the International Renewable Energy Agency (IRENA), renewable energy sources have five critical advantages over fossil fuels (IRENA, 2018). T he first advantage is related to employment. T he use of renewable energy sources has recently become rapidly widespread. The proliferation of renewable energy technologies in developed and developing countries creates significant employment opportunities in these sectors. T he second advantage is that they cause less or no air and environmental pollution compared to fossil fuels. In particular, wind, solar, and hydroelectric sources have the potential to create zero air pollution. Biomass and geothermal energy sources make deficient levels of environmental pollution compared to fossil fuels. Access to energy resources and uninterrupted energy supply is essential in regions where natural disasters occur. Renewable energy technologies can quickly provide energy access to areas where energy access is cut off in regions where earthquakes, floods, and hurricanes occur. The ease of installation of renewable energy technologies and the possibility of rapid installation facilitate energy access to disaster areas. Delivering electrical energy to small islands and rural areas in geographically challenging regions takes a lot of work. Meeting the energy needs of these regions with renewable energy technologies provides excellent convenience. In addition, using these energy sources will reduce dependence on fossil fuels. In this way, the adverse effects on the environment caused by CO2 emissions and the greenhouse gas effect caused by energy consumption can be minimized.
The answer is E.

Renewable energy sources can be categorized into six primary headings. The most well-known sources are solar, wind, geothermal, biomass, hydrogen, and water-based energy types. In addition, water-based energy sources can be divided into subheadings such as hydro, wave, tidal, ocean, and flow energy sources.
The answer is E.

Solar energy is preferred because it is an abundant, inexhaustible and a renewable energy source. It does not create waste such as carbon monoxide, sulfur, or radiation, and can be easily applied in every region because its technology is simple and its operating cost is relatively low. Also, it is not affected by foreign dependence on energy and bilateral country crises and solar energy can be used everywhere. In addition, the development of solar cell technology offers the opportunity for many different usage areas such as housing, workplaces, rural areas, agriculture and industry, transportation, communication, signaling, and automation as a heat and light source. Despite these advantages, there are also disadvantages, albeit limited. The need for large surfaces, the problem of storing the energy generated, little solar radiation during winter months and long nights, and high initial investment costs limit the use of solar energy.
The answer is B.

Wind energy is also natural, renewable, and environmentally friendly. The wind energy source is the sun; only 1-2% of solar energy is converted into wind energy. Since the sun does not heat the Earth equally, pressure and temperature differences occur. The wind is formed due to the displacement of air masses arising from these differences. The reasons for the differentiation of wind energy in different regions are the movement of air currents between high and low-pressure areas, the Earth’s rotation around its axis, surface frictions, regional heat dissipation, atmospheric events, and topographical differences of the terrains. The primary disadvantages of wind energy include regional variability and local variations due to factors such as differences in wind speed and intensity Additionally, wind energy entails high initial investment costs, impact on electromagnetic waves, and risks to bird deaths.
The answer is D.

Hydraulic energy, sourced from water, is the oldest renewable energy source,which started with grinding grain by operating mills with flowing water in ancient times, dates back to the past. Hydraulic energy is obtained by converting water energy into electrical energy thanks to the water’s flow and fall rate. Hydroelectric power plants offer positive externalities such as the possibility of transportation on the water in the region, the development of aquaculture and fisheries, prevention of erosion, creation of new employment, protection of water quality and prevention of water pollution.
The answer is D.

The heat and pressure collected deep in the Earth’s crust increase the temperature underground, and with this increasing temperature, underground water, steam, and gas form an energy source. Geothermal energy is obtained from underground hot water, steam, and gas leaking to the surface of the Earth. The underground hot water, gas, and steam pass through the turbines and convert the high temperature into electrical energy.
The answer is A.

The Eastern Mediterranean has become a region where the world’s eyes are on due to the presence
of many countries and its geographical location. This region constantly maintains and even increases its strategic importance due to its energy resources, increasing importance in trade and connection between many countries due to its geographical location. The natural gas and oil resources to be discovered in the Eastern Mediterranean have a high potential to change the balance in the region.
The answer is D.

Eastern Mediterranean is identified with natural gas. The answer is B.

The transportation of resources from the Eastern Mediterranean region to European countries is likely to be a more important issue than the issue of ownership. It is anticipated that the energy resources of the Eastern Mediterranean region will be an important alternative to the global natural gas trade. The Eastern Mediterranean region is the only alternative for reducing and even ending the dependence of European countries on Russia for natural gas.
The answer is B.

The objective of the SGC project is to enhance and diversify the European energy supply by transporting gas resources from the Caspian Sea to markets in Europe. There are four projects within the scope of the SGC: Lines are the operation of the Shah See natural gas condensate field (SD1 and SD2), the South Caucasus Pipeline Project (SCP), the Trans Anatolian Natural Gas Pipeline Project (TANAP) and the Trans-Adriatic Pipeline Project (TAP).
The answer is C.

Türkiye hosts two strategically important pipelines in the region, such as TANAP (Trans Anatolian Natural Gas Pipeline), which will transport Azerbaijan gas to Europe and TurkStream, which will transmit Russian gas to Europe.

Türkiye hosts two strategically important pipelines in the region, such as TANAP (Trans Anatolian Natural Gas Pipeline), which will transport Azerbaijan gas to Europe and TurkStream, which will transmit Russian gas to Europe.

The TurkStream project, one of the largest energy projects in the world and implemented in two lines, is an extremely important project that will contribute to the energy supply security of Europe, especially Türkiye. While natural gas will be supplied to Türkiye from one line of the TurkStream project, it is planned to transport natural gas to Europe, especially the Southern and Southeastern European countries, from the other line. With TurkStream, Russia provides energy from its large gas reserves directly to Türkiye and Southern and Southeastern Europe.
The answer is D.

The TANAP (Trans Anatolian Natural Gas Pipeline Project) is one of the most important indicators of successful cooperation between Türkiye and Azerbaijan in the field of energy.
The answer is A.

Issues such as conflicts between firms, consumers, countries, etc. are considered traditional energy issues. They are not new topics of conflict.

"Energy poverty can be defined as the lack of access to affordable and high-quality energy services.”

K-III; L-II; M-I
For instance, the main energy problems are different across sub-Saharan Africa, North Africa, the Middle East, and European countries. The main focus of sub-Saharan African countries is energy poverty, while the Middle Eastern countries (especially, OPEC members) aim is to maximize their revenue from energy export. Besides, European countries are interested in energy supply/demand security and diversification of energy sources.

The IEA’s main objective is to secure the energy supply (especially oil); however, its missions have extended in recent years. It suggests measures to improve the reliability, affordability, and sustainability of energy sources (IEA, 2023b).

The Agency for the Cooperation of Energy Regulators (ACER) is mainly interested in gas and electricity issues in the European Union. When necessary, it coordinates the efforts of national regulatory authorities in carrying out their regulatory duties (European Union, 2023).

The European Community Treaty is not one of the global energy agreements.

The Paris Agreement, which was adopted in 2015, seeks to keep global warming well below 2 degrees Celsius above preindustrial levels. The agreement includes countries’ pledges to mitigate greenhouse gas emissions, improve climate resilience, and support climate financing (United Nations, 2023a).

The Kyoto Protocol was one of the main international accords under the United Nations Framework Convention on Climate Change (UNFCCC) that was established in 1997 and went into effect in 2005. In order to tackle climate change, it established binding emission reduction objectives for industrialized countries that were responsible for the high current emission level in the atmosphere (UNFCCC, 2023)

Emerging markets (e.g., China, India, and the Middle Eastern countries) affect global energy markets significantly because their impacts on the global economy increase over time. For instance, world oil prices hit a record in 2008 due to an increased demand for oil by China and India (Schwarz, 2018). The high energy demand that comes from Eastern countries has increased the significance of the East compared to the West in the energy markets. For example, the share of the total energy consumption of OECD countries was 70.59% in 1965, while it decreased to 38.80% in 2022. It is seen that the weight of the non-OECD countries, mostly consisting of emerging markets, exceeded the share of OECD countries in the world energy demand (Energy Institute, 2023). Especially, China has especially become a key player in the global economy and has been an important share of the world’s energy consumption. ...

The economics of environmental sustainability is complex and multifaceted, examining the interplay between human economic activity and the natural world.
The answer is E.

The term efficient allocation is a fundamental concept. Efficient allocation refers to putting resources where they are most needed and effective. The idea centers on how scarce resources such as land and water are allocated in a way that maximizes the overall gain for society. When viewed through the perspective of environmental sustainability, the maximization of social welfare is accomplished throughout a number of time periods rather than just one.
The answer is C.

The answer is A.

The ‘Limits to Growth’ philosophy, emphasizes that our economic objectives must be balanced against ecological constraints.

Central to this exploration is the social cost of carbon (SCC), a concept in environmental economics that quantifies the economic damage associated with a marginal increase in CO₂ emissions in a given year. The SCC provides a monetary estimate of the harm caused by emitting an additional ton of CO₂ into the atmosphere. By calculating SCC, policymakers and businesses can better understand the long-term consequences of carbon emissions and make informed decisions to mitigate them. This estimation takes into account various factors, such as health impacts, agricultural losses, and damage to infrastructure, providing a comprehensive assessment of the true economic impact of carbon emissions.
The answer is C.

Global warming is non-rival because one country experiencing the negative effects of global warming does not mitigate the effects of another. Global warming is also considered non-excludable because its effects impact everyone, regardless of whether or not they contribute to the problem. Global warming can be both considered a global public bad and a global externality.

Sustainable Industry Strategy targets both the green and digital transition, often referred to as the twin transition, to reduce the carbon footprint through the presentation of clean technology solutions and the development of new business models.

'To improve air quality to reduce the number of premature deaths' is among the targets of 'zero pollution'.

To meet the targets outlined in the European Green Deal, EU countries need to create a 10-year integrated national energy and climate plan for the period 2021-2030. These plans provide a roadmap particularly addressing five areas: energy efficiency, renewables, greenhouse gas emissions reductions, interconnected energy systems, as well as research and innovation.

the European Green Deal is is specific to Europe and addresses the energy consumption of buildings mainly through the Renovation Wave Strate.

The Paris Agreement was adopted in 2015 as a legally binding treaty and is an international treaty addressing climate change.

Carbon leakage refers to a situation where a company relocates its production from a country with strict climate policies to a country that has laxer climate standards. As a result, greenhouse gas emissions increase, and the emissions resulting from this relocation are defined as carbon leakage.

The circular economy is an economic model that needs transformation both on the production and consumption side. On the production side, the CEAP introduces initiatives along the life cycle of products such as the design of the production process (sustainable product policy & eco-design) and waste reduction. On the consumption side, new habits will be incentivized with the ‘right to repair’ initiative which will promote sustainable consumption by providing consumers with the opportunity to repair defective goods. The CEAP promotes business models that involve sharing, leasing, reusing, repairing, and recycling materials and products for as long as possible.
