The main goal in this paper is to obtain low power consumption of wireless sensor nodes and collected distributed data in environmental parameters monitoring. Communication module and the controller should be in idle state as long as possible when they are not active. In design and development of Wireless Sensor Networks (WSNs), one of the main challenges is to achieve long lasting battery lifetime...
The smart grid concept offers an opportunity to design new environmentally friendly energy markets for reducing CO2 emissions. To achieve this goal, we should increase the use and penetration of green energy while softening our dependency on gray (non-environmentally friendly) energy too. In this work we show how load shifting and storage can be incorporated into new energy markets to reduce gray...
While the proliferation of cloud services have greatly impacted our society, how green are these services is yet to be answered. Although, demand escalation for green services has grown due to societal awareness, the approaches to provide green services and establish Green SLAs remain oblivious for cloud or infrastructure providers. The main challenge for cloud provider is to manage Green SLAs with...
ICT has tremendously evolved in the last decade and has now focused on sustainability. This research aims to evaluate the environmental impact of ICT for an SME. Existing ICT equipment of that organisation will be examined methodologically using ISO 14040 guidelines, the SusteIT ICT Carbon footprint Tool, the Environmental Paper Network paper calculator. Interviews have also been conducted to support...
We investigate how to manage an interactive service, where response time is a critical performance metric, to maximize the benefits of green energy produced from variable sources such as solar and wind. Specifically, we design, prototype, and evaluate a distributed structured storage system, GreenCassandra, which is representative of a class of important subsystems underlying many interactive cloud...
Due to increasing energy costs and the demand to lower CO2 emissions in the production, companies try to apply energy efficient technologies in green (new installations) and brown (modernized installation) production systems. Hence, the procedures of energy efficiency assessment have to be integrated with production systems on the machine control level. Presented work compares the energy efficiency...
Green IT is researched long time ago. IT service providers and users concerned with operating IT systems with less environmental charge. The behavior of hardware of an IT system is determined by software installed on it. Hence well behaved software participates in eco sustainability e.g. consumes less energy. Much research on ‘green software’ has been done since 2010. This paper examines the activities...
ICTs have a direct impact on the environment, consuming energy, materials and producing e-waste. But ICTs are the major enabling technology for mitigation of environmental impacts across all economic sectors. ICT applications and services can help limit energy use and material consumption. In other words ICTs can contribute in achieving more sustainable lifestyles, consumption and production. The...
China will more firmly embrace green and low-carbon development ideals and step up efforts in saving resources and protecting the ecological environment. Therefore, the green taxation policy is just part of a portfolio of possible policy changes. Under this background, this article summarizes many countries' green taxation policy, and explains the objective of polluter pays principle and the mechanism...
In response to increasing environmental problems and consciousness in relation to urbanization, more and more cities are trying to become eco-cities. We can question, however, whether these cities can be considered as sustainable cities. The eco-city concept usually includes criteria regarding energy and water consumption, transport, waste management, amount of green spaces, etc. However, food consumed...
The global is getting warm due to a great quantity of greenhouse gas which mainly consists of carbon dioxide emitted by human activities. As we all know, the majority of the total emission in greenhouse gas is emitted by Industrial enterprises. Therefore, enterprises should take social responsibilities for global action against global warming. Based on the basis of introducing “carbon neutral” conception...
Environmental policy making, green product rating, and marketing activities seem likely to drive the utilization of eco-assessments in the near future. In this paper we show from the example of EuP Preparatory Studies and other policy supporting studies some characteristics of ICT eco-assessments on different economical levels. We argue that the high diversity of individual cases coupled with technology...
