Based on three years of research involving a literature review, interviews, surveys, and an international workshop, this study first conceptualizes energy security as consisting of the interconnected factors of availability, affordability, efficiency, sustainability, and governance. It then...

Today, there are concerns related to security of energy supply, growing energy demands, limitations of fossil fuels, and threats of disruptive climate changes. To overcome the challenges, diversification and utilization of renewable energy resources are defined as the main strategies. However,...

World energy demands have been increasing rapidly, so natural gas sources in the world play significant role in order to meet those demands. The fastest consumption growth rate of the world's primary energy sources belongs to natural gas; in addition, it has the highest consumption growth rate...

Nowadays, the European natural gas production has declined having, as a consequence, increased import dependence, which is estimated to reach 85% by 2030. Therefore, the implementation of a European energy policy, towards the viability, competitiveness and security of energy supply, is more than...

A Compressed Air Energy Storage System is a means of storing energy which can then be used when the demand for energy increases. In this system, air is compressed in a cavern when power prices are low, and this air is used to run a natural gas-fired turbine to generate power when prices go up,...

Natural gas is a finite resource that may be estimated directly, through geophysical methodologies, or indirectly, through historical production data. The rapid growth in consumption of this limited natural resource, strictly connected to the oil economy, may lead to its imminent depletion and a...

This paper focuses on the relationship between bioenergy industry and energy security. The situation of fuel ethanol, biodiesel, biogas and biomass power industry of China in recent years has been introduced comprehensively. With a quick look at the existing bioenergy industrial development...

Facing the challenges of global warming, energy scarcity and energy price fluctuations, many countries consider energy security to be a major part of their energy policy and have started to develop relevant strategies. This study applies multi-dimensional energy security indicators to review the...

Industrialization, development and social transformation has brought together issues of over exploitation of limited energy resource base (e.g. fossil fuel), accelerated threats of energy insecurity, and liberation of greenhouse gas emissions across the continents. The global challenge for the...

The increasing prices and environmental impacts of fossil fuels have made the production of biofuels to reach unprecedented volumes over the last 15 years. Given the increasing land requirement for biofuel production, the assessment of the impacts that extensive biofuel production may cause to...
