“…There is a need to change the location of CDCs to reduce cooling costs and it can be done through placing the CDCs to that area which has availability of free cooling resources. Due to consumption of large amount of energy, CDCs are acting as a heat generator [130] [131]. The vapor-absorption based cooling systems of CDCs can use waste heat, then it takes away the heat while evaporating.…”

The cloud computing paradigm offers on-demand services over the Internet and supports a wide variety of applications. With the recent growth of Internet of Things (IoT) based applications the usage of cloud services is increasing exponentially. The next generation of cloud computing must be energy-efficient and sustainable to fulfil the end-user requirements which are changing dynamically. Presently, cloud providers are facing challenges to ensure the energy efficiency and sustainability of their services. The usage of large number of cloud datacenters increases cost as well as carbon footprints, which further effects the sustainability of cloud services. In this paper, we propose a comprehensive taxonomy of sustainable cloud computing. The taxonomy is used to investigate the existing techniques for sustainability that need careful attention and investigation as proposed by several academic and industry groups. Further, the current research on sustainable cloud computing is organized into several categories: application design, sustainability metrics, capacity planning, energy management, virtualization, thermal-aware scheduling, cooling management, renewable energy and waste heat utilization. The existing techniques have been compared and categorized based on the common characteristics and properties. A conceptual model for sustainable cloud computing has been proposed along with discussion on future research directions.

Surging in energy demand makes it necessary to improve performance of plant equipment and optimize operation of thermal power plants. Inasmuch as thermal power plants depend on fossil fuels, their optimization can be challenging due to the environmental issues which must be considered. Nowadays, the vast majority of power plants are designed based on energetic performance obtained from first law of thermodynamic. In some cases, energy balance of a system is not appropriate tool to diagnose malfunctions of the system. Exergy analysis is a powerful method for determining the losses existing in a system. Since exergy analysis can evaluate quality of the energy, it enables designers to make intricate thermodynamic systems operates more efficiently. These days, power plant optimization based on economic criteria is a critical problem because of their complex structure. In this study, a comprehensive analysis including energy, exergy, economic (3‐E) analyses, and their applications related to various thermal power plants are reviewed and scrutinized.

“…There are some other studies are done on ORC and VCC with separate cooling and power cycles with different working fluids to find desirable results [13,14,15,16,17]. Some other studies is also done using single working fluid for separate cooling cycles of ORC and VCC and found desirable combination for their system [18,19,20,21].…”

Cooling sector is highly dominated by conventional vapour compression system which have negative effect on environment. The solar rankine cooling system which runs on renewable energy and with environmental working fluids. Solar rankine system consists of two cycles, one is power cycle and another is cooling cycle. Power cycle is either solar rankine cycle or organic rankine cycle(ORC) and cooling cycle is vapour cooling cycle(VCC). To optimize the system there are some modification discussed in this paper. Solar heat source are widely available, so solar energy as a heat source for generator is an good option. This paper covers the basic rankine cooling system and modification in rankine cooling system to enhance the performance of system. But this cooling system still needed lots of work and research to make it as an alternative to conventional cooling system.
