The GreenLight project aims to construct a modular datacenter to improve energy efficiency. It will instrument the datacenter to closely monitor temperature, power utilization, and other metrics. Researchers will populate it with different computing architectures and investigate techniques for optimizing energy usage. The project also plans to directly power the datacenter with DC electricity from solar and fuel cell generators to avoid conversion losses.

Raritan Presents Green Data Centers Around the WorldRaritan
As cloud computing necessitates the use of more and more data centers on a global scale, technology firms have begun to embrace the use of renewable energy and other naturally available resources to increase efficiency and lower costs.

The present study focuses on the development of software (general mathematical optimization model) which has the following characteristics:
• It will be able to find the optimal combination of installed equipment (power & heat generation etc) in a Shopping Mall (micro-grid)
• With multi-objective to maximize the cost at the same time as minimizing the environmental impacts (i.e. CO2 emissions).
• To date, this tool is scarce to the industry (similar to DER-CAM, Homer).

Sizing of Hybrid PV/Battery Power System in Sohag cityiosrjce
This paper gives the feasibility analysis of PV- Battery system for an off-grid power station in Sohag
city. Hybrid PV-battery system was used for supplying a combined pumping and residential load. A simple cost
effective method for sizing stand-alone PV hybrid systems was introduced. The aim of sizing hybrid system is to
determine the cost effective PV configuration and to meet the estimated load at minimum cost. This requires
assessing the climate conditions which determine the temporal variation of the insolation in Sohag city. Sizing
of the hybrid system components was investigated using RETscreen and HOMER programs. The sizing software
tools require a set of data on energy resource demand and system specifications. The energy cost values of the
hybrid system agrees reasonably with those published before.
In this paper, a distributed incremental adaptive filter (DIAF) controlled utility interfaced photovoltaic (PV) - battery microgrid system is presented with power quality features. From protection aspects, grid tied solar inverters are required to shut down at loss of the utility. However, the multi-purpose PV-battery system is developed to provide energy to the critical loads, even at loss of distribution network. The bidirectional controlled converter with a battery also mitigates the intermittency of a PV array under rapid variations in the weather. The extracted maximum power is supplied to the voltage source converter (VSC), which is transferred to the nonlinear loads and the utility. The distributed incremental adaptive filter is used to control the VSC with contribution of PV power and the battery. In addition, the DIAF control provides harmonics mitigation, load balancing and power factor improvement functionalities in order to deal with system connected with nonlinear loads. A PV power feed-forward (PVFF) term is incorporated in the current control for injection of active power to the utility as well as to improve the dynamic operation of residential PV-battery microgrid. The battery energy storage (BES) reduces the fuel bills and it is also utilized to provide smoothing attributes to the microgrid. The effectiveness of PV-battery microgrid is validated experimentally developed in the laboratory.

Data Centers: Compute Faster and More Sustainably with Microconvective Cooling®JetCool Technologies
As the demand for AI, ML, and big data grows, data centers are facing significant energy challenges. It is estimated that 3% of the planet's total energy consumption is used by data centers with 30% of that attributed to cooling equipment.
Inferior in-rack cooling solutions use considerable energy and resources often requiring power- and water-intensive infrastructure like chillers and evaporative coolers. Depending on the local climate, these systems can be used year-round with U.S. data centers alone consuming an estimated 660 billion liters of water in 2020.
Processors rely on optimized cooling solutions to maximize power density and increase compute performance. With suboptimal cooling solutions, heat can cause processor throttling and limited device lifetime. As power density and processor performance increase so do the expectations for cooling technology.
Recognizing the need for a simple, scalable, and sustainable liquid cooling option for data centers, JetCool developed SmartPlate. SmartPlate is a simple water cooling system that outfits processors with a fully-sealed, drop-in replacement cooling solution that lowers chip temperatures by 37%. SmartPlate technology helps accelerate performance by extracting 30% faster processing for TDPs over 1,000 Watts. Sustainability is one of JetCool's primary principles. Our consumers use 50% less electricity and 90% less water than the competing liquid cooling solutions. Reach out to our team to learn more about partnering with JetCool today.
Multi-objective Pareto front and particle swarm optimization algorithms for p...IJECEIAES
The progress of microelectronics making possible higher integration densities, and a considerable development of on-board systems are currently undergoing, this growth comes up against a limiting factor of power dissipation. Higher power dissipation will cause an immediate spread of generated heat which causes thermal problems. Consequently, the system's total consumed energy will increase as the system temperature increase. High temperatures in microprocessors and large thermal energy of computer systems produce huge problems of system confidence, performance, and cooling expenses. Power consumed by processors are mainly due to the increase in number of cores and the clock frequency, which is dissipated in the form of heat and causes thermal challenges for chip designers. As the microprocessor’s performance has increased remarkably in Nano-meter technology, power dissipation is becoming non-negligible. To solve this problem, this article addresses power dissipation reduction issues for high performance processors using multi-objective Pareto front (PF), and particle swarm optimization (PSO) algorithms to achieve power dissipation as a prior computation that reduces the real delay of a target microprocessor unit. Simulation is verified the conceptual fundamentals and optimization of joint body and supply voltages (V thV DD ) which showing satisfactory findings.
