“…In that sense, the impact of the electricity mix for heating during the winter could be higher than the one for cooling during summer when solar power or wind can be used. Based on the research of Walzberg et al (2019) an overestimation of on average 13% for GWP was found for the CandianCanadian mix. Further, this research highlighted that the influence of considering hourly mixes depends on the system and electricity mix studied (Walzberg et al, 2019).…”

Besides, on the long term, a reduction in the heating demand and increase in the cooling demand will also influence the total environmental impact.…”

“…However, Walzberg et al [17] pointed out that the time consideration factor is indispensable for evaluation of the environmental impact of DSM. In other words, accepting DSM does not always have a positive effect on the environment; only DSM that is bound to time considerations can have a positive effect on it.…”

Advances in the introduction of fluctuating renewable energies, such as photovoltaics (PV), have caused power-system destabilization. However, stability can be improved if consumers change the way they use power, moving to time slots when the PV output in an area is high. In large cities in developed countries, where the types of distributed energy resources are varied, demand side management (DSM) in which consumers share power supplies and adjust the demand has received considerable attention. Under effective DSM that uses the latest information and communication technology to maximize the use of renewable energy, we believe that sparing use of appliances is not the only solution to address global warming. If behavioral change shifts the use of domestic appliances from one time slot to other time slots, we do not have to abandon the use of these appliances. The aim of this study is to determine the possibility of such behavioral changes in people in order to provide basic information for operating an effective DSM. To that end, we conducted a questionnaire-based survey of 10,000 households in Japan. We investigated the proportion of people responding to a request for a demand response (DR) under the given presented reward in time slots when DSM by DR is required. We also analyzed the factors influencing people’s response to a request for a DR. Furthermore, based on the rewards likely to be achieved in the adjustable power market, we estimated how much adjustable power would be realized.

“…There are a wide range of fields related to ICT, and many studies have examined the environmental impact of ICT from an environmental aspect; smart cities [8][9][10], smart homes and buildings [11][12][13][14], transportation [15][16][17][18], teleworking [19][20][21], and ICT equipment [22][23][24]. In the field regarding consumer experiments, Matsuno et al [25] compared CO 2 emissions from listening to music through Compact Disc (CDs) and online streaming.…”

In this study, we analyzed the CO2 emissions of online music and video streaming services, as one of the digital contents, in Japan using life cycle assessment. As a system boundary of online music and video streaming, processes such as data center construction and server manufacturing, usage of communication networks and internet communication technology devices (personal computers (PCs) and smartphones), and disposal of data centers and servers were considered. Data were collected using statistical and online surveys, and CO2 emissions per 1 MB of communication volume were calculated. One of the results revealed that the lifecycle CO2 emissions of listening to online music using PCs and smartphones were 5.88 × 10−4 and 1.43 × 10−4 kg-CO2/MB, respectively. The overall CO2 emissions for domestic music and video streaming services in 2019 was 921 thousand t-CO2. Online video streaming accounted for 87.7% of the total emissions, which corresponded to approximately 0.23% of domestic CO2 emissions derived from electric power generation.
