This paper introduces a new scheme called Green MPLS Fast ReRoute (GMFRR) for enabling energy aware traffic engineering. The scheme intelligently exploits backup label switched paths, originally used for failure protection, in order to achieve energy saving during the normal failure-free operation period. GMFRR works in an online and distributed fashion where each router periodically monitors i...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...

Energy costs are notoriously uncertain but what is the effect of this on energysaving investments? We find that real-option frictions imply a novel equilibrium response to increasing but uncertain energy costs: early investments are cautious but ultimately real-option frictions endogenously vanish, and the activity affected by higher energy costs fully recovers. We use electricity market data f...

Taking the provincial capital, labor and energy as inputs, regional GDP as output from 1995 to 2007, the paper quantifies the vertical and lateral energy saving potential by introducing the radial adjustment and slack adjustment of DEA. The results show that by the vertical, the achievement of energy saving in 2007 is better than their respective historical performances. By horizontal, in 2007 ...

In order to design the energy transition process, strategies to gain high energy saving potentials are needed. To assess the primary energy demand of a building stock of about 3,5 million buildings a model originally used for calculating the heat demand of rural districts was adapted. To close the gaps in the statistical data many assumptions had to be made. The impact of the assumptions had to...

In order to reduce building energy consumption and make wall insulation materials meet fire protection requirements, the authors put forward a kind of saving model exterior under green nanomaterials. Mainly using PBECA calculation software. By setting up multi-component, multi-material method. The aggregate in light device modified by nanomaterials is simulated analyzed, agent area compared. ef...

Energy saving is a paramount concern in wireless sensor networks (WSNs). A strategy for energy saving is to cleverly manage the duty cycle of sensors, by dynamically activating different sets of sensors while non-active nodes are kept in a power save mode. We propose a simple and efficient approach for selecting active nodes in WSNs. Our primary goal is to maximize residual energy and applicati...

China is one of the major energy-consuming and carbon-emitting countries. Promotion of efficient energy use is crucial in reducing energy consumption and carbon emission. Under external pressure and realizing the importance of energy conservation, many firms have adopted measures to save energy. Such measures entail active employee participation. However, employees often lack motivation and thu...
