The revolution of shale gas in the United States (the US) has become a phenomenon at the beginning of the 21st century. It has been significantly influencing the United States' economy and the global gas market. Like America, other countries have also been searching for shale gas. However, the conditions for developing this resource are very different among regions and nations. On the other hand, there are also many doubts, debates and even strong oppositions to the development of shale gas because of the complicated issues that arise regarding its extraction, and also due to the fact that its impacts are not fully known. Therefore, at present, the development of shale gas is still a big question for regions, countries that have potential and desires to exploit such resources. Although it is difficult to identify all necessary or sufficient conditions to develop shale gas, the experiences of the United States could be instructive for other countries. In this article, the potential development of shale gas in China and Europe is analyzed, which relies on the fundamental conditions considered as important factors for the success of the shale gas industry in the US. Through these analyses and we demonstrate the difficulty of developing this resource outside North America.

Natural gas is considered an important bridge in the transition of energy in the world. However, the development and management of unconventional gas now face many challenges. This paper aims to provide an overview of what would be required to formulate and implement the trend of energy transition and natural gas use in the world. Selected managerial issues regarding the role of natural gas are presented, including chosen statistical data on natural gas consumption, forecasts for the demand for natural gas, and the potential of unconventional gas. The empirical part of the study examines the impact of natural gas consumption on the GDP of 14 G20 countries during the period of 1994 to 2018. The pooled mean group model (PMG) is employed in this study. Based on the cointegration test results, it was found that natural gas consumption and population have a long-run relationship with CO₂ emissions. Consistent with other studies, we found a positive relationship between CO₂ emissions and natural gas consumption, GDP, and population.

The issues of energy and the environment are one of the main challenges for humanity today. Global growth in energy demand is facing environmental concerns, especially in fast-growing regions such as Asia. Transferring traditional energy sources such as coal, oil, to cleaner energy sources and renewables is an inevitable trend in the future. With good characteristics compared to other fossil fuels, natural gas can play an essential role in the energy transition process towards a low-carbon economy. The success of the shale gas revolution in the USA has created a lot of interest globally, especially in countries with potential for these resources. Asia, especially China, is estimated to have the world's largest shale gas resource. However, the question about the development of these resources is still a big question. This article will evaluate shale gas development prospects in Asia, particularly in China, by analysing the fundamental conditions that are important factors for the success of shale gas in the USA.

With high economic growth, Vietnam is now witnessing an increasing energy demand, having much potential for renewable sources such as wind energy, solar energy or biomass energy. The nation is heavily dependent on fossil energy sources such as coal and oil. This situation raises concerns about both energy security and the environment. Therefore, a question arises if Vietnam can develop renewable energy to solve energy demand, energy security and reduce climate change impacts as committed. This article analyses a considerable potential for renewable energy sources (especially wind and solar energy). The analysis also indicates competitiveness between these renewable energy sources compared to the traditional energy sources that Vietnam is dependent on, especially when there are policies to encourage the development of renewable energy and limit emissions. This article proposes some recommendations to develop renewable energy sources, with an overview of replacing fossil energy in Vietnam.
