divided into three main sections, power generation, transmission, anddistribution. The power generation consists of a power plant that produces power from renewableor non-renewable energy sources at low to medium voltage. This voltage is then increased inorder to transmit the power from the generation site to the distribution site. At the distributionlevel, the voltage is again reduced for the consumers. Power transformer, in this case, plays avery important role to step up and step down the voltage. There have been many advancementsin the conventional transformer, mainly magnetic coils, materials, cooling system, manufacturingprocess etc., but the advancements of the transformer structure and functions are first proposed in[1] where power

The major source of air pollutioncomes from vehicular emissions. Therefore, cars and truck fleets have been considered and carrymajor responsibility for the environmental issues, faced at least at urban level. The constantlyincreased total amount of vehicles worldwide corresponds to increased energy consumption andenormous emissions, both during their production and use phases. To overcome this problem, carmanufacturers have designed and developed several types of environmentally friendly vehicles,mainly based on electric motors. The types of these vehicles are battery powered
and manufacturing sectors, restructuring theutilities, smart grid, and low-carbon economy require graduates with a broader understanding oftechnology, economics, social contexts and skills [1-5]. There are growing recognition of theneeds to improve, restructure and reform electrical energy and power engineering curricula. Theissues surrounding this theme are receiving significant interests form faculty, industryprofessionals and often administration. Electrical energy professionals are required to havesignificant scientific capabilities, deep interdisciplinary understandings, and soft skills, e.g. self-learning abilities, communication or interpersonal competence. However, how and which are thebest approaches to better educate the next

Engineering program was conducted.II. IntroductionIn the early 2000’s, forecasters believed the United States was on the verge of a nuclearrenaissance. Tremendous growth in the energy industry was expected at that time since theaverage age of the nuclear power sector was 48 years of age which ranked among the oldest inany US industry 1. Many colleges and universities geared up new programs with help fromfederal agencies such as the Nuclear Regulatory Commission (NRC) and the Department ofEnergy (DOE). Over 40 college programs across the country were developed to create a pipelineto help fill the shortage of workers 2. The majority of the programs were two-year Associatedegree programs designed for entry level positions in nuclear fields. At that

In all, theproject was a difficult, but rewarding experience for everyone involved.IntroductionExperiential learning theory defines learning as "the process whereby knowledge is createdthrough the transformation of experience. Knowledge is a result of a combination of graspingand transforming experience” [1]. Experience created by overcoming the challenge to perform anenergy conversion of a prime mover is regarded as a convergence approach. The convergingstyle dominates learning areas of abstract conceptualization and active experimentation.Individuals with such learning preferences work best with technical tasks and problem solving.This learning style is best suited for people who enjoy experiments, simulations

renewableenergy technologies are explored to expand the portfolio of renewable energy, ocean renewableenergy is becoming an increasingly researched topic. The ocean is still a largely untapped sourceof energy. One type of ocean renewable energy, Ocean Thermal Energy Conversion (OTEC),can produce up to 10 TW of power (almost 4 times the power used by the world) withoutnegatively affecting the ocean environment [1],[2]. Additionally, this power source is stable andpredictable. Research on this technology is especially helpful for students to learn and applythermodynamics, fluid mechanics, and heat transfer concepts.OTEC is an energy technology that harnesses the difference in temperature between the cold ofthe deep ocean and the warmth of the ocean surface

These courseshave traditionally given students’ difficulties due to the abstract and “hard to visualize” nature ofthe course. The implementation of COMSOL into these courses is discussed.IntroductionDesign should be at the forefront of the educational process for electrical engineeringundergraduate students. Design has been defined as “a process by which human intellect,creativity, and passion are translated to useful artifacts” [1]. The National Academy ofEngineering has stated several times that design is essential to improving student learning [2],[3], [4].The EE program at the University of Pittsburgh, on the other hand, has traditionally beencentered around

. Power grids need to provide power continuously withhigh reliability. Currently, the US grid is very reliable; the grid remains down for less than0.04% of the year on average for the nation [1]. However, the rise in global temperaturescorrelates to a rise in frequency of natural disasters [2]. Heavier and more frequent rainfalls willonly increase the importance of grid reliability. Reliability represents the ability of the grid towithstand abnormal operating conditions [3]. During these potential outage conditions, whethernatural or man-made, the largest failures happen in the distribution system, not the generationlayer [3]. This was recently seen on a very large scale in Texas. While common solutions, suchas relaying or burying wires
suited as the primary power source. While hydrogen fuel cells areefficient, they cannot provide instantaneous increase in power, say if a vehicle needed toaccelerate, whereas battery power can. This group of students, in the development of FCHEV,explore these problems and determine how battery configuration, management, and switchingsystem can provide solutions. A key component to any FCHEV is the Battery Management System (BMS). A capableBMS will be able to monitor the state of charge (SOC) and state of health (SOH) of batteriesconnected to it. SOC describes the amount of potential energy the battery has remaining in asingle discharge [1], like the gas gauge on a car describing the amount of fuel left. SOHdescribes the ability of the

IntroductionSolar energy is clean, free, and abundant. It holds the potential to support a clean, reliable, andmore sustainable energy future. From the years 2000 to 2019, global cumulative installedphotovoltaic (PV) capacity has increased by 632.4 GW [1]. In 2019 alone, 116.9 GW of new PVwas installed. It was estimated that global solar PV installation in 2020 would increaseapproximately 132 GW from 2019. Despite the impact of pandemic on the economy, the UnitedStates installed 11.1 GW of solar PV in the first 9 months of 2020 which is the largest first 9-month total ever [2]. With the

Once the student has reached a certain level of confidence in their knowledge, wemove on to other stages where more theoretical concepts are introduced. Our methodology isbased on three tasks: (1) field visits; (2) literature; (3) computer applications; (4) mathematicsand science. In this work, we used the existing campus facilities to introduce students to the systemsused to heat the campus. Our aim is to expose the early college students to the installation of thepower plant, without focusing on theoretical aspects, thermodynamic cycles, and properties offluids, but focusing on understanding the functionality of systems, as it comes from the driverswho take care of the power plant
to reduce FW.Introduction and BackgroundEvery year approximately 40% of the food produced in the United States [1] (approximately onethird, globally [2]) is wasted rather than eaten. Food is wasted or discarded throughout the foodsupply chain, creating significant economic, societal, and environmental impacts. The U.S.Environmental Protection Agency (EPA) estimates that 63.1 million tons of food waste (FW)were generated from commercial, institutional, and residential sectors in the United States in2018, with an additional 40 million tons generated from industries [3], [4]. Along with thatwasted food is the wasted farm land, water, labor and energy resources required to grow,process, package and transport it. According to the NRDC, food waste
