During various periods, the United States (the US) has adopted diverse policies for achieving selfsufficiency in supplying its required energy. Technological revolution that has begun from a decade ago pursues the goal of energy independency. Using new technologies for developing its unconventional oil and gas resources, the United States has taken steps in line with the accomplishment of its objective of energy independence. Numerous articles have examined the various technical, economic and political aspects and consequences of the US technological revolution. This paper, in a new and innovative approach based on theoretical framework of neorealism, aims to show the implications of technological revolution in energy sector on the US dependency on fossil energy imports. Efforts will be made to find an answer to this main question as to what effects have the technological revolution occurrence in energy sector had on the US dependency on the fossil energy imports? In response, the study's main hypothesis is that, the US policy to exploit the unconventional oil and gas resources through technological revolution can be elaborated within the framework of the self-sufficiency strategy for energy production in line with the reduction of the threats stemming from dependency on the oil and gas imports.

There is no doubt that Saudi Arabia exports the most oil. The country has considered notable investments in Renewable Energy to diversify its economy and decrease dependence on oil export. The research aims to analyze the key factors that have influenced Saudi Arabia's renewable energy policy. The main question of our article is: What are the influential factors in Saudi Arabia's energy policy on renewable energy sources? In response, the research hypothesizes that the growing energy consumption of Saudi Arabia and its favorable geographical location for renewable energy production caused the country to invest in renewable energy for its energy mix, economy, and carbon emission reductions. To investigate the research hypothesis, we have used the theoretical framework of energy security by Benjamin Sovacool. The findings show that Saudi Arabia’s capital investments in renewable energy provide opportunities for the government to create a modern industry that creates jobs and revenue with the support of the private sector. Furthermore, industries and residences use renewable energy for electricity. Therefore, renewable energy has decreased fossil fuel dependence and diversification of the country's energy mix consumption. Data are collected through the library method. The analysis method is descriptive.

«Soft power» is a set of activities designed by a government or regional and international actors aimed to influence external public opinion, promote external image or attract support for a particular policy, which is implemented through all the available tools and new technologies. The non-governmental actors also play an effective and important role in this diplomacy. Considering the public diplomacy and soft power of the Islamic Republic of Iran as a deliberate and conscious approach can be of great importance in the country's grand strategies that will strengthen national interests in the domestic sphere and influence them at regional and global levels. The article analyzes the role of Iran’s soft power in confronting Iranophobia. The study is aimed at presenting a theoretical definition of public diplomacy and soft power in foreign policy and international system, and then examines its role in the foreign policy of the Islamic Republic of Iran with an emphasis on confronting Iranophobia.The authors answer the research question: “What is the role of soft power in the foreign policy of the Islamic Republic of Iran in confronting Iranophobia?” The research method is descriptive-analytical based on historical evidence, documents, and analytical issues of theorists, authors, and media being expressed in the theoretical framework of soft power. The paper is based on a synthesis of Stephen Walt’s “balance of threat” theory with Alexander Wendt’s social constructivism to explain the Iranian “threat” in American foreign policy.The findings of this research show that without the use of force and disturbing the balance in the international relations, using a variety of tools and instruments the Iranian public diplomacy and soft power might be effective to reduce the global and regional atmosphere of Iranophobia and undermine anti-Iranian solidarity.
