Today the energy consumption of Information and Communication Technology (ICT) industry is a significant contributor to the total energy demand in many developed countries. Recent studies show that the ICT industry is responsible for about 2% of the global emission of CO2 and this percentage is predicted to increase as the Internet expands in bandwidth and reach. In this chapter we highlight di...

the rice conversion process is an agricultural transformative industry that consumes a great deal of fossil fuel and electricity. in this study, the effect of different factors on energy consumption, energy consumption index and whitening index were investigated. the experimental design was a split plot design with four whitening periods (15, 30, 45, 60s) (main plot), three rice varieties (khaz...

 Among the most important factors affecting energy consumption in the building sector are social and economic conditions, the culture of energy consumption, geographical and climatic characteristics of a city, the role of a city, efficiency of energy supply and consumption systems, and physical/spatial parameters of buildings and residential fabrics. Addressing urban form through planning ...

application of appropriate agricultural operations is a strategy to reduce energy consumption and greenhouse gas emissions from agricultural productions process. in this study, fuel consumption and greenhouse gases emissions values for each farm operation was evaluated in gorgan and ali-abad katol to soybean product. all activities and production processes about operations were monitored and re...

existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. According to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

Nowadays, there are lots of problems in Cloud data center such as high energy consumption and low efficiency. We model a cloud environment with physical hosts and virtual machines, and design an Energy-Aware Virtual Machine Scheduling strategy (EAVMS) to reduce energy consumption and improve utilization rate by integrating system resource such as computing, storage and bandwidth resources. Expe...
