The use of biofuels for road transport in Sweden has increased during the past 10years as policymakers stimulate demand in response to concerns about climate change. Using a supply chain approach, this paper analyses: (i) existing biofuel supply chains in Sweden (biogas, biodiesel and...

The question of increasing biofuels production and the development of different biofuels production technologies has become controversial. On the one hand, production of corn-based biofuels creates a ‘food/feed vs. fuel’ tradeoff condition, along with subsequent uncertainties for both...

China is facing serious issues involving energy sufficiency, greenhouse gas (GHG) emissions and air pollution caused partly by the rapid growth of vehicles. In order to relieve those problems, new energy vehicles are introduced into the bus and car market. We adopt life cycle analysis to...

The supply security of fossil fuels is one of the most important policy issues in South Korea. This is because of South Korea’s economic condition, geopolitical status, and lack of energy resources. This study investigates the Korean public’s perceptions of the supply security of fossil...

Few previous studies consider the GHG implications of biofuels in electricity generation. Yet, the biofuels have become a key replacement for residual petroleum fuel and LNG in stationary power in Hawai‘i. This stems from isolated island grid and heavy dependence on imported oil,...

This paper describes the nexus of energy justice, supply and security. It advances the case that energy justice is the relatively new concept in this triangle of issues and an area requiring research. There are three central tenets of energy justice: distributional, procedural and recognition...

There are increasing concerns that physical material constraints threaten energy security and the growth of emerging technologies. Traditional approaches to quantify material criticality utilize single-score metrics which are narrowly focused on physical scarcity and often lead to...

This research explores the relationship between technology scale, energy security and decarbonisation within the UK energy system. There is considerable uncertainty about how best to deliver on these goals for energy policy, but a focus on supply chains and their resilience can provide useful...

Transitioning to a sustainable energy supply will be critical to meeting future economic and environmental goals. This transition will require optimizing and commercializing a portfolio of new clean energy technologies. However, many promising clean energy technologies are based on materials...

After the Fukushima nuclear disaster, a reassessment of the energy system is needed in order to include such aspects as human security and resilience. More open and careful discussions are needed concerning the various risks and uncertainties of future energy options, both in Japan and globally....
