Governments and the Private Energy Sector: Analysis of Energy Sector and Relationship between State

: A symbiotic relationship exists between the state and the energy sector that often leads to conﬂicting relationships between the two. The best example of this complicated relationship is between the state and free markets is the case of the United States, European Union, and Global Energy Sector. The decline in the gas import—due to sanctions placed on the Russian Federation—to Europe from Russia, along with other counties that import gas from Russia, has negatively affected the economies of European counties. The Russian government has restructured the exporting of gas to other counties in order to continue to sustain companies’ growth. This literature review will analyze how sanctions against Russian Federation have affected the energy market and how it will affect entire energy markets.


Introduction
A symbiotic relationship exists between the state and the energy sector that often leads to conflict between these two entities in the global market.The best examples of such complicated relationships are the cases of the United States, the European Union, and the global energy sector.The main industries in the world market are oil and natural gas, which play essential roles in the economy worldwide and are the main fuel sources for every country on every continent [1].Oil has been the leading cause of wars since 1973 [2].Conflicts over oil can occur due to competition over shipping lanes and pipelines, oil-related terrorism, petrol aggression, and resource scarcity in consumer states [3].In 2014, the Autonomous Republic of Crimea became part of the Russian Federation after a referendum that took place, and people voted in a referendum for integration with the Russian Federation, which resulted in integration with the Russian Federation.This has led to sanctions on Russia that remain in place today.Russia has received 5532 to date, which is more than Iran has received (3616) [4].The countries that have imposed sanctions on Russia are Switzerland (568), the European Union (518), Canada (454), Australia (413), the United States (243), the United Kingdom (35), and Japan (35) [5].
In September 2021, Gazprom (a Russian energy company) completed Nord Stream 2, which has provided an additional pipeline to import oil in order to support the growing economy of Europe and its consumers' needs.Figure 1 shows that Nord Stream 2 and Nord Stream connect Germany and Russia directly, eliminating transit countries such as Ukraine, Austria, Belarus, and Poland.Even though Nord Stream 2 is complete, the pipeline has not received certification to begin operation.This situation will be analyzed by economists of the European Union to determine how this decision has affected the German, EU, and global economies and energy markets.In this research paper, I will analyze the energy market and how it has changed due to the current economic and political environment.It is quite important to gain an understanding of how the state influences and affects the energy market and economies worldwide.

Results
Oil and gas have been some of the leading causes of global conflicts among vario nations.
These are the mechanisms that explain such conflicts:  Resource wars: state(s) attempt to obtain oil sources by force;  Petro-aggression: state(s) take on risky international policies;  The exteriorization of civil wars in oil: internal conflict for oil and gas;  Financing uprising: funding terrorist organization(s) such as ISIS;  Divergences triggered by the expectation of oil-market supremacy: for example, th United States began a war with Iraq to take control of Kuwait's oil sources in 1990;  Conflicts over control of oil transit channels: for example, pipelines and shipping o

Results
Oil and gas have been some of the leading causes of global conflicts among various nations.Oil-related impediments to multidimensional support: when a distributor's attempts to show preference for a petrostate preclude multidimensional collaboration on security concerns [11].
There is a link between oil and global conflicts that is strengthening due to a significant transition in the global energy sector.A major shift has occurred in the energy industry today, which has affected the energy industry and, as a result, economies worldwide.Natural gas prices have increased by 46% or more this year [12].For example, the cost of gasoline in Aventura, FL, on 10 June 2022, ranged from USD 4.99 to 5.99 per gallon; in the United Kingdom, the average price of gas is USD 9.77 per gallon [13], and in the European Union, it is USD 7.78 per gallon [14].Despite the ability to diversify using clean energy, we still rely heavily on gas and oil, as well as coal.
The energy industry has been evolving as the demand for clean energy has increased to preserve the climate and clean air.Figures 2 and 3 below show how energy consumption has changed over the years as demand from consumers has increased due to population growth as well as the growth of factories, plants, and other commercial infrastructure.In 2018, oil accounted for 31.6% of the energy supply, whereas in 1973, it accounted for 46.2%, revealing a decrease of 14.6% [15].However, the share of coal in the energy supply increased from 24.5% in 1973 to 26.9% in 2018, a 2.4% increase [15].Also, the share of natural gas in energy supply increased from 16% in 1973 to 22.8% in 2018 [15].In addition, there is a shale oil reserves at global estimation is at 345 billion barrels, which 75 billion of barrels reserves belongs to Russia, 58 billion barrels belongs to United States, and 35 billion barrels belongs to China [16].The rest of shale oil reserves belong to: Argentina (27 billion barrels), Libya (26 billion barrels), Venezuela (13 billion barrels), Mexico (13 billion barrels), Pakistan (9 billion barrels), Canada (9 billion barrels), and Indonesia (8 billion barrels) [16].One could argue that the demand for clean energy has increased and will continue to increase due to newly developed polices and regulations for clean and renewable energy [17].

The global population is increasing by 1% each year.According to data from World Population View [19], the world population in 2022 was 7,953,303,361, a 1% increase from 2021, whereas in 2021, the population was 7,874,965,825 [19].This leads to increased demand for energy, which in turn consumes two billion oil barrels, and electricity usage is expected to increase by 52% by 2040 [20].The population currently obtains 80% of its energy supply from fossil fuel, which includes nuclear power; biofuels; and hydro, solar, wind, and geothermal energy [21].

Fossil Fuel History
A black rock that was found to be coal was discovered in China 4000 years ago.According to some archeologists, this is when humans used the first fossil fuel [22].About 1900 years ago (100-124 CE), in present-day Iraq, natural gas was discovered, but at that time, people did not realize its importance as a fuel source for domestic use [22].Today, natural gas is used for domestic purposes, such as heating and cooking.Figure 5 shows how fracking is conducted and extracted.

Natural Energy Consumption/Import
Renewable energy plays an important part in U.S. and global energy and in decreasing greenhouse gas emissions.The United States planned to diversify the energy imports from five main countries in 2021: Mexico, Canada, Russia, Saudi Arabia, and Colombia.It imported around 8.47 million barrels per day of petroleum from 73 countries.Petroleum consists of crude oil, hydrocarbon gas liquids, and refined petroleum products (gasoline, diesel fuel, and biofuels).The United States imports around 6.11 million barrels per day of Scientists have established that fossil fuels (coal, oil, and natural gas) are made of the remains of plants and animals which are found in the earth's crust and contain carbon and hydrogen that can be burned for energy [23].Today, many scientists around the world are seeking to ensure that there will be enough fuel and that the environment is not affected, because this would have a negative effect on human life.

The International Energy Agency (IEA) [27,28] reported that the development of capricious gas generated in the United States and its future expansion to China and Europe will challenge business operations for gas exporters [29].Russia is ranked ninth in terms of recoverable shale gas in the industry; the top nations that recover shale gas are China, Argentina, and Algeria [30].The IEA (2012) predicted that the United States might surpass Russia in shale gas development and become the world's largest natural gas producer [31].
The U.S. Energy Information Agency [32] estimated that China possesses the world's largest recoverable shale reserves, of 31.6 tcm (1275 tcf).In addition, BP (2013) has stated that Russia will remain the largest gas exporter to the European Union and the United States.Despite numerous sanctions imposed on Russia, the European Union and the United States still depend on imports of natural energy.Sanctions placed on Russia's financial sector prevent the receipt of payments for gas and oil exported to European countries.
The Russian state will provide all necessary support to ensure Gazprom's effective and efficient operations in the global energy industry and maintain its competitiveness in the global energy market [33].Gazprom resumed the development of South Stream in 2017, and it was competed in 2020, resulting in diversification due to the use of the Ukrainian pipeline.Gazprom no longer relies on this transit line as of the end of 2019 [34].This led Ukraine to object, as it will be losing great financial gain from transit, but the objections did not affect the South Stream project, which was completed and is being used today as one of the main routes for importing gas to Eastern Europe and Europe itself.
In turn, Russia has decreased exports of natural energy to the European Union and the United States.How will the energy market be affected, considering the current decrease in gas/oil imports to European countries and the United States?

How the Energy Market Has Changed since Sanctions against Russia
In 2014, the first sanctions were imposed on Russia, and more sanctions were imposed in 2022.Some of these were economic sanctions that restricted Russia from receiving funds in both EUR and USD for exported gas/oil.In addition, Germany did not issue a certificate for the Nord Stream 2 pipeline, preventing the export of gas from Russia to Germany [35].Furthermore, Russia has refused to export gas/oil until payment is made in its local currency (RUB).On 28 March 2022, Russian President Vladimir Putin asked the Russian Central Bank, the government, and Gazprom to develop a proposal by 31 March 2022 for a gas payment plan in RUB that would be applied to "unfriendly countries" and the entire European Union [36].The Russian president's statement means that the European Union, Britain, Canada, Japan, Switzerland, Ukraine, and the United States, which have imposed sanctions, will have to purchase RUB with USD or EUR at a rate that Russia's Central Bank determines in order to purchase gas for exports [36].receiving funds in both EUR and USD for exported gas/oil.In addition, Germany did not issue a certificate for the Nord Stream 2 pipeline, preventing the export of gas from Russia to Germany [35].Furthermore, Russia has refused to export gas/oil until payment is made in its local currency (RUB).On 28 March 2022, Russian President Vladimir Putin asked the Russian Central Bank, the government, and Gazprom to develop a proposal by 31 March 2022 for a gas payment plan in RUB that would be applied to "unfriendly countries" and the entire European Union [36].The Russian president's statement means that the European Union, Britain, Canada, Japan, Switzerland, Ukraine, and the United States, which have imposed sanctions, will have to purchase RUB with USD or EUR at a rate that Russia's Central Bank determines in order to purchase gas for exports [36].This policy would strengthen the Russian RUB because the demand to purchase would increase.Today, the price for crude oil per barrel is USD 113.06, and it has been increasing for the past 3 months.Once governments become involved in industry, such as the energy sector, in negative ways, it will result in a negative outcome.Gas prices have increased greatly worldwide, especially in countries that have implemented sanctions against Russia.These countries did not analyze the outcome of the sanctions placed on Russia's banking system and the energy sector, and this will result in a negative outcome and hinder their own economies.Ping [38] stated that 13,382 sanctions were imposed on Russia between 2014 and 2022.
For example, gasoline prices in the United States range from USD 5 to 7, depending on the state, which results in increased prices for all goods for citizens.In March 2022, inflation in the European Union stood at 7.8%, an increase from 6.2% in February 2022 [39].According to the European Commission, inflation had increased in July 2022 to 8.9% [40].According to Branis [3], sanctions against Russia have affected the profits of corporations in the United States and Europe, as well as the GDPs of some countries.In other countries, including in the European Union, prices for energy and goods have increased as well.
The UK government has been informing its citizens that energy prices will increase; as a result, many families have begun to limit their spending by minimizing the use of their heating system for long periods and dining out less often [32].This policy would strengthen the Russian RUB because the demand to purchase would increase.Today, the price for crude oil per barrel is USD 113.06, and it has been increasing for the past 3 months.Once governments become involved in industry, such as the energy sector, in negative ways, it will result in a negative outcome.Gas prices have increased greatly worldwide, especially in countries that have implemented sanctions against Russia.These countries did not analyze the outcome of the sanctions placed on Russia's banking system and the energy sector, and this will result in a negative outcome and hinder their own economies.Ping [38] stated that 13,382 sanctions were imposed on Russia between 2014 and 2022.

Nelson [8] [14] According to the EU Commission, as Figg [11] stated that this will make it possible to save enough oil to fill 120 super tankers and save enough natural gas to heat 20 million households [39].European leaders are asking citizens to reduce energy usage to support their leaders' agenda, which is quite destructive to these leaders' economies and citizens.
In January 2022, Germany shut down the last 6 nuclear reactors that were left of a total of 19, and the last 3 will be closed at the end of 2022 [1].Many will argue that this is an unwise decision that will prevent Germany from decarbonizing and will place Germany in a challenging position and increase the energy crisis in the country, leading to factory and plant shutdowns [37].In addition, Russia is a major supplier of palladium (40%), which is essential for vehicles (it decreases harmful emissions into the atmosphere), and 30% of titanium, which is essential for the aerospace industry (such as Airbus, which will be complying with sanctions), is exported from Russia [7].This will greatly affect Airbus and its production, but to comply with European sanctions, the company is willing to endure a of titanium.Despite accusations that gas/oil prices have risen due to Russia, the supply of gas/oil has been disrupted by the COVID-19 pandemic, the interlinking of the natural gas industry globally, and unpredictability in the pricing of energy due to diversification from fossil fuels to green energy [39].

Projection 2050
Developing countries are working towards diversifying from oil and gas consumption into clean energy that will minimize emissions into the atmosphere.During the pandemic in 2020, the global emissions decreased by 4.9%, which is recorded as the biggest drop since 1960 [41].However, in 2021, emissions have increased by 0.1%, reaching a level higher than that in 2019 [33].During the pandemic, travel was restricted; thus, less air traffic as well as less automobile traffic led to fewer emissions into the atmosphere.All countries collectively are aiming towards net zero emissions by 2050, but there are some countries that continue to contribute to the increase in emissions.There are 100 countries that contribute to emissions, but their contributions account for 2.9%, whereas three countries contribute to 42.6% of emissions [33].These countries are China, the United States, and India (emissions measured in millions of tons in CO 2 ): 1.
China → more than 10,065 million tons of CO 2 released; 2.
Russia, being fourth on the list of emitters, is working towards minimizing emissions by 33% by the year 2030 in order to minimize the greenhouse effect on the climate [42].In addition, countries such as South Africa, Vietnam, and Indonesia have come to a decision to minimize emissions, as they are major coal consumers.They are reverting to clean energy due to the Just Energy Transition Partnerships pact, an organization led by the United States and additional Group of Seven countries [14].
On 30th November 2023, OPEC+ held a meeting, and upon completion of the summit, countries have come to a conclusion to voluntarily cut down by a total of 2.2 million barrels per day [43].The countries from OPEC which have decided to cut down on oil production are: Saudi Arabia (1000 barrels per day); Iraq (223 thousand barrels per day); United Arab Emirates (163 thousand barrels per day); Kuwait (135 thousand barrels per day); Kazakhstan (82 thousand barrels per day); Algeria (51 thousand barrels per day); Oman (42 thousand barrels per day); and Russia (500 thousand barrels per day) [43].This agreement was reached in order to establish stability in the oil and energy market.

Discussion Section
This study focused on an analysis of how sanctions placed on the Russian Federation have affected the countries that imposed these sanctions, such as the European Union, the United States, some Latin American counties, Japan, and Sri Lanka.The sanctions that have been imposed on Russia are the largest sanctions that have been imposed in history.The countries that have imposed sanctions on Russia expected them to harm Russia's economy and create instability in its government, but the reality of the sanctions is not what was expected.Europe and various countries are enduring the effects of the sanctions against Russia, such as increased energy, product, and food costs.Europe has decided to decrease or completely eliminate the usage of Russian gas/oil, but has not considered how such a policy would affect its economy or industries.As aforementioned, the cost of energy and other goods has increased drastically.
European leaders are directing citizens to use less energy and water to cut the costs of energy usage.This coming winter, European countries are facing difficult times regarding energy and its usage.European leaders need to focus more on their citizens' welfare and not their ambitions to punish Russia for the so-called invasion of Ukraine.The cost of energy will continue to rise unless Nord Stream 2 is given certification and begins its operations.The German government has decided not to certify Nord Stream, which has led to an energy crisis in the European Union.If European leaders forego personal ego and consider their citizens' welfare, people will not have to decrease energy use in their homes, use less water, or spend conservatively on groceries.The question is, how long will European leaders be willing to continue on the current path of converting to "alternative energy" and leaving their citizens in dire economic conditions?Only time will tell.

These are the mechanisms that explain such conflicts: O Financing uprising: funding terrorist organization(s) such as ISIS; O Divergences triggered by the expectation of oil-market supremacy: for example, the United States began a war with Iraq to take control of Kuwait's oil sources in 1990; O Conflicts over control of oil transit channels: for example, pipelines and shipping of oil through Ukraine; stated that many citizens' energy bills have increased by 54%, which will create more dire living conditions for millions.The European Union Commission's recommendations to save energy are as follows: O Turn down heating and use less air conditioning O Adjust your boiler's settings O Work from home O Use your car more economically O Reduce your speed on highways O Leave your car at home on Sunday in large cities O Walk or bike short distances instead of driving O Use public transport O Skip the plane and use the train
