Webinar on "Experiences and Learned Lessons from an Air Free-Cooled Tropical Data Center Testbed
Date: April 20, 2021, 9 AM Singapore Time (GMT+8)
The air free-cooling has been long thought infeasible in tropics due to the unique challenges of year-round high ambient temperature and relative humidity. In recent years, the increasing availability of servers that can tolerate higher temperatures and relative humidity levels sheds light upon the feasibility of the air free-cooling to enhance the data center energy efficiency. However, building an air free-cooled data center in the tropics requires extensive experiments to understand the details of how the realistic tropical environment conditions will affect data center power consumption, computing throughput, and server hardware reliability. This presentation will talk about the key observations, experiences and learned lessons from the experiment that was conducted. The experiments show that (1) the air free-cooling design that uses fans only can reduce the power usage effectiveness (PUE) by 38%, compared to the global average PUE, (2) the tropics’ year-round high temperatures up to 37 degree Celsius do not impede the air free-cooling, and (3) the implementation of the air free-cooled data centers in tropics requires special cares to deal with airborne contaminants to avoid fast corrosion rate and dust-induced server faults. Presentation will also highlight the energy resilience of Singapore and its carbon footprint..

Webinar on "The importance of Solar Resource Assessment and Monitoring in PV Power Plant Performance"
Date: April 23, 2021, 7 PM Indian Standard Time (GMT+5:30)
This presentation will provide an overview of the importance of Solar Resource Assessment and Monitoring in the feasibility study and in the performance of Solar PV projects, along with a case study of a Solar Radiation Resource Assessment (SRRA) station in Southern India. Simulation models and meteorological forecasting resources for specific PV plants are the well proven technologies which are currently in use. In this context, data collection and monitoring represent a valuable opportunity to improve PV plant performance and yield forecasting. The improvements in communication procedures between devices would contribute to improving daily and intraday forecasting, calculation of performance expectations, and the exchange with the energy grid. Solar Resource Monitoring is also important for monitoring the performance of Microgrids in remote areas which can help the unprivileged and vulnerable communities. The traditional and advanced data monitoring techniques like IoT, Big Data Analytics etc. are also discussed in this presentation.

Webinar on "Electric Vehicles and the Electric Grid"
April 29, 2021, 11 AM US Eastern (GMT -4)
How will the electric distribution grid manage the adoption of electric vehicles? This talk will review how the electric distribution grid will manage the growing adoption of EVs. It will discuss the early concerns by electric utilities and automotive manufactures and how they have adapted since the early plug-in electric vehicles arrived over 10 years ago and what the challenges are today and in the near future. It is not only the large rollout of light duty EVs that are being introduced but also the great challenge of how electric utilities will manage the multi-MW charging by EV fleet vehicle owners. There will also be a discussion on how various standards bodies are helping to ensure that EVs can become a friendly grid load and a resource asset.

Webinar on "Clean Energy: Using Supercomputing Simulations to advance our understanding"
Date: April 6, 2021, 4 PM US Eastern (GMT-4)
Supercomputing has come a long way from simple weather forecasting to advanced predictions about many phenomena, such as ocean, atmospheric, land, high altitude and critical land-water-air ecosystems. A lot of this became possible thru giant strides in computer calculation power, connection capability as well as improved scientific models and extensive simulation supporting software. In this talk we will learn a little bit about how, when all this is combined with ever growing data plus expert domain knowledge, it can be employed to better explore and design clean energy solutions and its potential impact on our society.

Webinar on "Nuclear energy: The Need, the Perception and the Reality"
Date: April 9, 2021, 9 PM Indian Standard time (GMT+5:30)
Nuclear energy arises from and holds together the binding energy that is accumulated in the
centre of an atom. Nuclear power refers to the use of nuclear reactions that trigger nuclear
energy to produce heat, which is then used most commonly in steam turbines to generate
electricity in a nuclear power plant.
Electricity from nuclear power plants has a vital role to play in India’s energy mix and future development. Nuclear power also has inextricably got linked to the broader issue of climate change. Nuclear power has now been strongly linked to the larger topic of climate change.The passive safety relies on natural factors such as pressure differentials, gravity or natural convection to ensure protection during emergency situations. This includes the fast injection of high pressure boron and the provision of extra tanks for long term supply of borated water to the reactor in a passive way. The reactor building has a series of passive hydrogen recombiners to convert abnormal production of hydrogen into water. The presentation will also provide an overview about Nuclear Energy, its application & future scope. We will also be discussing various reactors used in Kudankulam Nuclear Power Plant.
