This work addresses the problem of high energy consumption and carbon emissions by data centers which support the traditional computing style. In order to overcome this problem we consider two allocation scenarios: single allocation and global optimization of available resources and propose the optimization algorithms. The main idea of these algorithms is to find a server in the data center wit...

BACKGROUND Architectural methods that take into account global environmental conservation generally concentrate on mitigating the heat load of buildings. Here, we evaluate the reduction of carbon dioxide (CO2) emissions that can be achieved by improving heating, ventilating, and air conditioning (HVAC) technologies. RESULTS The Climate Change Research Hall (CCRH) of the National Institute for...

An end-use energy model is presented for assessing policy options to reduce greenhouse gas emissions. This model evaluates effects of imposing a carbon tax on various carbon-emitting technologies for reducing CO2 emissions. It also estimates effects of combining a carbon tax with subsidies. The problem can be formulated as two-level mathematical programming. An algorithm is proposed and applied...

Due to limited energy resources, excessive emission of CO2, global warming, increase of mean temperature, serious impacts have resulted on our living environment, and thus, energy saving and carbon reduction have become urgent issues. Planting grass, flowers and trees can absorb and reduce CO2, thus meeting the requirements for energy saving and carbon reduction in environmental protection. At ...

Increasing energy price and requirements to reduce emission are new challenges faced by manufacturing enterprises. A considerable amount of energy is wasted by machines due to their underutilisation. Consequently, energy saving can be achieved by turning off the machines when they lay idle for a comparatively long period. Otherwise, turning the machine off and back on will consume more energy t...
