It is important to evaluate impacts of fossil fuel price hikes and climate stabilization that force the global energy system to adopt alternative and efficient technologies by routing future energy system dynamics into a different technology roadmap. Hence, a high-regional-resolution and...

Given its importance as a practical phenomenon underlying the progress of learning technologies, attention should be paid to the role of subsidisation in learning theory, particularly in the case of nascent climate-related sociable learning technologies, in order to examine its benefits. Thus,...

This study estimates global time-series consumption-based GHG emissions by region from 1990 to 2005, including both CO2 and non-CO2 GHG emissions. Estimations are conducted for the whole economy and for two specific sectors: manufacturing and agriculture. Especially in the agricultural sector,...

Industrial energy efficiency is of paramount importance both for conserving energy resources and reducing CO2 emissions. In this paper, we compare specific energy consumption among countries in fossil power generation, steel, and cement sectors. The evaluations were conducted using common system...

Maximizing renewables in the country's power system has been a key political agenda in Japan after the Fukushima nuclear disaster. This paper investigates the potential of PV resource, which could be systematically integrated into the Japanese power system, using a high time-resolution optimal...

This paper examines the potential roles of Fischer-Tropsch (FT) synfuels in the 21st century with a global energy model treating the entire fuel supply chain in detail. The major conclusions are the following. First, FT synfuels become a major alternative fuel regardless of CO2 policy due to...

As of November 2008, a new market, the CO2 free electricity market, started pilot trading within the Japan Electric Power Exchange (JEPX). The electricity in this market comes from renewable resources, nuclear or fossil thermal power with CDM credits. The demanders of the CO2 free electricity...

In this study, emission reduction potentials in greenhouse gases (GHG) are assessed by country, sector, and cost using a GHG emission reduction assessment model with high resolutions with respect to region and technology and high consistency in terms of assumptions, interrelationships, and...
