“…While many studies revealed that the ICT had an energy saving effect [15][16][17], there are also some studies argued that it could stimulate energy use through various mechanisms [18][19][20][21], and some studies noted the differences of ICT's impacts among sectors [22] or groups of economies [23]. According to Takase and Murota [24], the overall impact can be divided into an income effect and a substitution effect. Regarding the income effect, the ICT, as a type of general purpose technology, is broadly related to production activity and residential life which involve energy use, so that its development can induce energy demand by stimulating economic growth [25].…”

“…Regarding the income effect, the ICT, as a type of general purpose technology, is broadly related to production activity and residential life which involve energy use, so that its development can induce energy demand by stimulating economic growth [25]. Regarding the substitution effect, the ICT sector may reduce energy use by replacing the traditional sectors, given that the ICT sector and its products are relatively less energy-intensive [24][25][26]. Moreover, Hilty and Hercheui [27] argued that, while the above effects happened in short and medium term, the most meaningful impact of ICT on human behavior and society might happen in the long run.…”

ICT Development and Sustainable Energy Consumption: A Perspective of Energy Productivity

2018

View full text Add to dashboard Cite

Abstract:The information and communication technology (ICT) is closely related to the future of global energy consumption, not only because the ICT equipment itself increasingly consumes energy, but also because it is a general-purpose technology which may affect energy use of almost all sectors. Given the controversy over the net energy-saving effect of ICT, this paper focuses on a new perspective, i.e., energy productivity, to investigate the relationship between ICT development and energy consumption. Using a data panel of 50 economies over the period of 1995 to 2013, results of the Malmquist energy productivity index generally indicate an unbalanced development of energy productivity across the globe, while results of the patent-based ICT knowledge stock indicate a huge gap of ICT development comparing the high-income economies with the others. Furthermore, regression results indicate that ICT development is significantly related to energy productivity improvement. Finally, this paper suggests accelerating ICT development in underdeveloped economies, given the global common task of sustainable energy consumption.

“…In Japan and the USA, Takase and Murota (2004) examines the effects of ICT investment on energy consumption and CO 2 emissions. They divide the effect of ICT investment on energy use into substitution and income effects, and they conclude that Japan energy saving as a result of investment in ICT, but the increasing ICT investment in the USA would increase energy use.…”

Impact of Information Communication Technology and Economic Growth on the Electricity Consumption: Empirical Evidence from 67 Countries

2015

View full text Add to dashboard Cite

This study investigated the impact of information communication technology (ICT) and economic growth (GDP) on electricity consumption (EC) for a global panel consisting of 67 countries using a dynamic panel data model. We also implement these empirical models for three income panels, namely, high income, middle income, and low income panels. The panel model was used in this study from the period 1990-2012. Our main findings show a positive and statistically significant effect of ICT on electricity consumption when ICT measured using Internet connections and mobile phones. Moreover, the results indicate that economic growth has a positive and statistical significant effect on electricity consumption for four global panels. Financial development is found to have a positive impact on electricity consumption in global panels, middle income, and low income panels. For the high income and middle income, the population has a positive and statistical significant effect on electricity consumption.

“…Our analysis compares with the studies listed in Table 1 as follows. First, we based our analysis on the computable general equilibrium (CGE) model, whereas most previous analyses are based on input-output analysis [8] or econometric analysis [9]. A CGE model enables us to carefully analyze the effects of structural changes on an economy and on industries.…”

SUMMARYWe created a mathematical model of the Japanese economy using a macro-economic modeling framework called a computable general equilibrium model. We used the model to estimate the impacts of the ubiquitous network technology advances on CO 2 emissions in Japan. Four scenarios of the ubiquitous network society in Japan in 2010 were selected. The four scenarios correspond to four different levels of ubiquitous society advancement. In each scenario, we estimated electricity consumption by electronics products, the effects of ubiquitous network application systems on improving energy efficiency, and the industrial structural changes induced by the expansion of the ubiquitous network application services market. Our results indicate that advanced ubiquitous technologies would potentially reduce the CO 2 emissions of the Japanese economy by 2.8%.
