TLDR
This chapter investigates the circumstances under which this new CloudC infrastructure is likely to reduce energy use of the authors' new digital lifestyle, or when it simply catalyses a rebound effect that could hamper ICT-related energy savings.Abstract:
Cloud Computing (CloudC) is one of the most prominent recent trends in the digital communications sector and represents a paradigm shift within the ICT industry. The supply of popular applications, such as cloud storage and cloud video streaming, has caused a surge in the demand for CloudC services, which offer the advantages of low economic cost, high data transfer speeds, and improved mobility, security, scalability, and multi-tenancy. In this chapter, we investigate the circumstances under which this new CloudC infrastructure is likely to reduce energy use of our new digital lifestyle, or when it simply catalyses a rebound effect that could hamper ICT-related energy savings. We classify CloudC rebound effects as either direct or indirect rebound effects, and we discuss the differences and overlap between rebound effects, enabling effects, and transformational effects. An understanding of these differences is important for understanding energy use associated with CloudC.read more

Digitalization and energy consumption. Does ICT reduce energy demand
TL;DR: In this article, the authors investigate the effect of digitalization on energy consumption using an analytical model, and investigate four effects: (1) direct effects from the production, usage and disposal of information and communication technologies (ICT), (2) energy efficiency increases from digitalization, (3) economic growth from increases in labor and energy productivities and (4) sectoral change/tertiarization from the rise of ICT services.

How LCA contributes to the environmental assessment of higher order effects of ICT application: A review of different approaches
TL;DR: In this article, the authors examined whether and how case studies on environmental effects of ICT already take into account related higher-order effects, such as rebound and induction effects, and found that most studies chose an attributional LCA approach.

Digitalization and the Decoupling Debate: Can ICT Help to Reduce Environmental Impacts While the Economy Keeps Growing?
TL;DR: In this article, the authors examined whether digitalization helps or hinders an absolute decoupling of environmental throughput from economic growth, and concluded that a more active political and societal shaping of the process of digitalization is needed to make ICT work for global environmental sustainability.

Digital sufficiency: conceptual considerations for ICTs on a finite planet
Tilman Santarius,Jan C. T. Bieser,V. Frick,Mattias Höjer,Maike Gossen,Lorenz M. Hilty,Eva-Maria Kern,Johanna Pohl,Friederike Rohde,Steffen Lange +9 more
TL;DR: In this paper , the authors argue for comprehensive policies for digital sufficiency, which are indispensible if ICT are to play a beneficial role in overall environmental transformation, and propose a set of strategies and policy proposals: (a) hardware sufficiency which aims for fewer devices needing to be produced and their absolute energy demand being kept to the lowest level possible to perform the desired tasks; (b) software sufficiency that covers ensuring that data traffic and hardware utilization during application are kept as low as possible.

Environmental saving potentials of a smart home system from a life cycle perspective: How green is the smart home?
TL;DR: In this paper, the authors examined the environmental saving potential of a smart home system (SHS) with smart heating in Germany from a life cycle perspective and showed that minimum savings of 6% of annual heating energy over 3.1 years for PED and over 2.4 years for GWP need to be realised by an SHS in order to exceed the environmental effects caused by their production and operation.

Review: A survey on security issues in service delivery models of cloud computing
S. Subashini,V. Kavitha +1 more
TL;DR: A survey of the different security risks that pose a threat to the cloud is presented and a new model targeting at improving features of an existing model must not risk or threaten other important features of the current model.

Energy efficiency and consumption — the rebound effect — a survey
TL;DR: In this paper, a review of some of the relevant literature from the US offers definitions and identifies sources including direct, secondary, and economy-wide sources and concludes that the range of estimates for the size of the rebound effect is very low to moderate.
The rebound effect: an assessment of the evidence for economy-wide energy savings from improved energy efficiency
TL;DR: The UK Energy Research Centre (UKERC) has launched a major new report on how "Rebound Effects" can result in energy savings falling short of expectations, thereby threatening the success of UK climate policy.

On Global Electricity Usage of Communication Technology: Trends to 2030
Anders S. G. Andrae,Tomas Edler +1 more
TL;DR: An estimation of the global electricity usage that can be ascribed to Communication Technology between 2010 and 2030 suggests that CT electricity usage could contribute up to 23% of the globally released greenhouse gas emissions in 2030.
