In the current context of environmental and global challenges, eco-innovation has become one of the European Union's priorities. A proper measurement system is a need for the promotion, long-term decision making and progress assessment of eco-innovative activities. Public and private sectors...

The objective of this study is to examine the potential for a full transition to domestically produced biofuels in the Stockholm County transport system in 2030, without exceeding the proportional share of national bioenergy assets. This target is chosen in order to test the potential of biofuel...

Providing energy without unfavorable impacts on the environment is an important issue for many countries. Wave energy is one of the renewable resources with high potential and low impact on the environment, especially in coastal regions. The estimation of the wave characteristics is essential...

Life cycle analyses of renewable energy sources focus on static accounting of energy and green house gases balances. In this work, we introduce a conceptual framework and a mathematical model to simulate the time evolution of the energy balance of energy conversion technologies. This approach...

Following the 2011 Fukushima nuclear disaster, Japan is having to re-design its energy policy. With the danger of nuclear power in an earthquake-prone country exposed, renewable energies are being seen as a potential alternative. An assessment of the feasibility of a 100% renewable energy...

There is a growing perception by society of the risks of dramatic global climate changes due to anthropogenic greenhouse gases, in particular energy related emissions of CO2. This has spurred a renewed interest in carbon free or carbon neutral technologies for converting sources of renewable...

We try to understand the role of technological change and diffusion of energy efficient technologies in order to explain the trend of energy intensity developments in the German steel industry. We selected six key energy efficient technologies and collected data to derive their diffusion since...

The importance of technology heterogeneity in estimating economy-wide energy efficiency has been emphasized by recent literature. Some studies use the metafrontier analysis approach to estimate energy efficiency. However, for such studies, some reliable priori information is needed to divide the...
