AbstractThe Japanese power system has unique characteristics with regard to variable renewable energies (VREs), such as higher costs, lower potentials, and less flexibility with the grid connection compared to other major greenhouse-gas-emitting countries. We analyzed the role of renewable energies (REs) in the future Japanese power sector using the results from the model intercomparison project Energy Modeling Forum (EMF) 35 Japan Model Intercomparison Project (JMIP) using varying emission reduction targets and key technological conditions across scenarios. We considered the uncertainties for future capital costs of solar photovoltaics, wind turbines, and batteries in addition to the availability of nuclear and carbon dioxide capture and storage. The results show that REs supply more than 40% of electricity in most of the technology sensitivity scenarios (median 51.0%) when assuming an 80% emission reduction in 2050. The results (excluding scenarios that assume the continuous growth of nuclear power and/or the abundant availability of domestic biomass and carbon-free hydrogen) show that the median VRE shares reach 52.2% in 2050 in the 80% emission reduction scenario. On the contrary, the availability of newly constructed nuclear power, affordable biomass, and carbon-free hydrogen can reduce dependence on VREs to less than 20%. The policy costs were much more sensitive to the capital costs and resource potential of VREs than the battery cost uncertainties. Specifically, while the doubled capital costs of VRE resulted in a 13.0% (inter-model median) increase in the policy cost, the halved capital costs of VREs reduced 8.7% (inter-model median) of the total policy cost. These results imply that lowering the capital costs of VREs would be effective in achieving a long-term emission reduction target considering the current high Japanese VRE costs.

Bioenergy contributes significantly towards the share of renewable energies, in Europe and worldwide. Besides solid and liquid biofuels, gaseous biofuels, such as biogas or upgraded biogas (biomethane), are an established renewable fuel in Europe. Although many studies consider biomethane technologies, feedstock potentials, or sustainability issues, the literature on the required legislative framework for market introduction is limited. Therefore, this research aims at identifying the market and legislative framework conditions in the three leading biomethane markets in Europe and compare them to the framework conditions of the top six non-European biomethane markets. This study shows the global status and national differences in promoting this renewable energy carrier. For the cross-country comparison, a systematic and iterative literature review is conducted. The results show the top three European biomethane markets (Germany, United Kingdom, Sweden) and the six non-European biomethane markets (Brazil, Canada, China, Japan, South Korea, and the United States of America), pursuing different promotion approaches and framework conditions. Noteworthy cross-national findings are the role of state-level incentives, the tendency to utilise biomethane as vehicular fuel and the focus on residues and waste as feedstock for biomethane production. Presenting a cross-country comparison, this study supports cross-country learning for the promotion of renewable energies like biomethane and gives a pertinent overview of the work.

The challenge of renewable energies has now come to a strategic step. While 80% of the energy still comes from fossil fuels, the role of renewable energies is in constant growth. The challenge of renewables is not only a technological transition, but also the indispensable response to the needs of the planet, from the incessant demographic growth to climatic emergencies and to the development of the poorest countries, and eventually to medium to long term challenges such as the colonization of Mars. Researchers are therefore committed to developing innovative, clean and efficient solutions to meet such challenge. In particular, organic dyes, organic molecules such as those founds in drugs or liquid crystals, represent key actors of one of the most fascinating chemistry frontiers to produce low cost and clean renewable energy. As the true colors of the Sistine Chapel frescoes, wanted by Michelangelo, have now emerged and visible to everyone, also in this field only specific colored dyes are able to address effectively the energy challenge. The scientist, especially the chemist, starting from the state of the art and innovation, is engaged in the design of new molecules owning the correct colors.

This article provides an overview of the structure and utilization of the new EU member states (EU-13) energy consumption. During the analysis, it was determined which non-renewable energy carriers were replaced by renewables ones. The replacement of energy sources with each other was analyzed by means of a correlation matrix. Results indicated that coal was replaced by renewable energies in Poland, Czech Republic, Slovakia, Bulgaria and Cyprus. Furthermore, the renewables basically replaced oil in Malta and gas was replaced by renewables in Lithuania. In other countries the relation between renewables and non-renewables could not be detected. The structure of energy production in the EU countries were different due to the differences of natural endowments. The main goal of the European Union energy policy is to reduce the CO2 emission by decreasing the fossil fuel consumption and this finding new ways to replace traditional energy sources is of utmost importance.

The Subject

In the search of sustainable process and products, ecofriendly policies have been developed over the years, aiming at reducing the environmental impacts as a step toward sustainability. Among the environmental impacts, alternatives to mitigate the greenhouse gas emissions - GHG stand out due to the concerns with climate change. Then, the development and use of renewable resources become relevant. Considering that supply chains are intense in energy consumption and GHG emissions (since involves processes related to supply, production, transport, consumption), it becomes relevant to investigate if the management of sustainable supply chain are considering the renewable energies in their processes. Therefore, this paper aims at mapping the role of renewable energies in the context of sustainable supply chain, analyzing the literature published at Web of Science database - WoS about the subject. The main researchers, organizations, collaboration networks were presented, and the 21 most cited studies were mapped in this paper. The research was carried out with the papers published at WoS until 2019, using VantagePoint software to handle information. The findings show that the research about renewable energy in the context of sustainable supply chain has been growing, especially since 2010. Moreover, biomass, biofuels and photovoltaic energy were the most recurrent sources of renewable energy studied by most cited papers. However, the theme presented itself as new and that there are still potential to be explored.
