Although the electric vehicle reduces pollutant emissions and results in reduced energy costs, lack of battery charging infrastructure and relatively high vehicle prices create challenges to the automobile industry and affect government support policies. To create a battery charging...

This empirical study examines changes in industrial productivity in Korea between 1980 and 2009, focusing on how investment in information and communication technology (ICT) and energy use, influence productivity levels. A dynamic factor demand model is applied in order to link inter-temporal...

Energy consumption has been drastically changed because of energy source depletion, price fluctuations, development and penetration of alternative energy sources, and government policies. Household energy sources are interrelated, and energy price and household characteristics, such as income...

With the increasing importance of natural gas (NG) in the energy mix, the search for a reliable liquefied NG (LNG) supply has received great attention along with energy security in Korea. However, the current level of LNG supply reliability in Korea is much lower than that in other...

This empirical study examines productivity changes in Japan and South Korea during 1973–2006 and 1980–2009, respectively, in order to assess how investment in information and communications technology (ICT) affects energy demand. A dynamic factor demand model is applied to link...

E-mail is an efficient communication tool, but at the same time it is an efficient vehicle for Internet pollution in the form of spam—unsolicited, bulk e-mailings. Spam is a global phenomenon, and debate about possible means of controlling it is lively. Spammers impose a negative externality...

National energy planning has become increasingly complex owing to a pressing need to incorporate sustainability considerations. In this context, we applied least-cost and cost-risk optimization models to allocate energy sources for sustainable development in the Korean electric power generation...
