“…Specifically, the impact of ICT can be disaggregated into positive effects (e.g., income effect) and negative effects (e.g., substitution effect and direct technological effect). For different economies at different development stages, the relative magnitudes of these disaggregated effects may vary so that the dominant effects would represent the direction of ICT's overall impact [4,25]. Thus, the so-called controversy over the role of ICT in reducing energy demand is reasonable, since the complicated impact mechanism and varying dominant factors would make both positive net effect and negative net effect possible in theory [4].…”

“…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 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].…”

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

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.

Using satellite remote sensing data and the threshold panel model, this research explores the impact of urban spatial structure on urban energy intensity. The evaluation index of urban spatial structure includes compactness and elongation rate. Results from empirical studies of 30 cities in China from 1996 to 2016 indicate that urban spatial structure has a significant impact on urban energy intensity. There is a positive correlation between urban spatial structure elongation rate and urban energy intensity. However, with the increase in urban fixed assets investment, there is a negative correlation between elongation rate and energy intensity, which implies an inverted‐U relationship. The results also indicate that urban compactness is negatively correlated with urban energy intensity. Therefore, proper management of urban spatial structure can effectively promote the reduction in urban energy intensity. The elongation of urban suburb space and the compactness with the internal space of the city can be developed simultaneously. While playing the role of a spatial agglomeration economy, the negative effects of over agglomeration are avoided, which jointly promote the reduction in urban energy intensity.

An intelligent grid system makes the combination of various renewable energy technologies and changes in power supply and demand become more possible. Technology and innovation are considered the primary drivers of the next stage of economic growth in China, and smart grid (SG) energy management has developed as an emerging industry with the goal of lowering greenhouse gas emissions and increasing energy efficiency to attain sustainability. In this study, high‐level, middle‐level, and low‐level managers from 102 successful grid companies in China completed questionnaires. The particular characteristics of four business models for innovation (novelty, lock‐in, complementarities, and efficiency) are discussed, three distinct levels of SG (power supply side, grid side, and customer demand side) are considered (addressing process and elements), and effects of each business model for innovation are identified. Our findings yield important considerations for companies in the SG energy industry on how to successfully adapt their business models for innovation.
