Essays on Energy

Abstract The electric power system is facing a great number of challenges nowadays. Energy efficiency and environmental impact have to be considered for each component of the power grid. The power system operator need better grid reliability while dealing with an aging infrastructure. So, a...

Oil, coal, and natural gas are non-renewable energy sources known as fossil fuels which are currently the world’s primary source of energy. These are formed by prehistoric plants and animals that died over a million years ago and were gradually buried by layers of rock....

I’ve been really interested in renewable and sustainable energy sources for a while. While there are many sustainable, renewable energy sources that can be used on a large scale and sold to consumers, I will discuss smaller scale systems that can be implemented within an...

1. ABSTRACT In this study, phones, wearable/portable devices, detectors that detect temperature and human motion are integrated as smart sensors to reduce the amount of energy used for air conditioning and ventilation. Advanced Smart sensors get input feedback from mobile phones, smart gadgets and portable...

Introduction In the last few years, a range of energy-storage device applications has expanded from portable electronics to large-scale energy storage systems, including renewable energy storage and electric transportation [1,2]. To fulfill the energy and power density requirements for energy applications, many researchers have given...

There are many forms of renewable energy. Most of these renewable energies depend in one way or another on sunlight. Wind and hydroelectric power are the direct result of differential heating of the Earth’s surface which leads to air moving about (wind) and precipitation forming...

There are many numberless stories of science and till to date most of them are demystifying, and out, darkness is one. So far, no one can decide what darkness is and from where it continues to exist and why rights are overbearing to remove darkness....

A new kind of supervised learning approachis proposed to determine the number of occupants in aroom in order to use these estimate for improved energymanagement. It introduces the concept of Parametrizedclassifier. It relies on the predetermined structure ofsupervised learning classifiers, where any classifier couldbe used...

In this essay we will try to analyze the characteristics of different energy sources on the following parameters: Environmental Impact Coal A typical coal power plant (500MW capacity) generates the following pollutants:3. 7 million tons of CO2 equivalent to cutting 161 million trees. 10, 000...

Wind The U. S. Department of Energy estimated 404 gigawatts of wind energy capacity across the country by 2050, up from 89 GW today, if electricity demands hold steady that would fulfill one third of the energy demands of the entire country. But wind power...

Energy consumption is inevitable for human existence. There are various reasons for the search of an alternative fuel that is technically feasible, environmentally acceptable, economically competitive, and readily available. The first primary reason is the increasing demand for fossil fuels in all sections of human...

Renewable energy generation nowadays is crucial to preserve the coal reserves of our planet as well as reduce the carbon levels and other pollutants in the atmosphere. Micro/Nano energy generation means that the generation of energy is on a small scale. It was found in...

Gender inequality leads to poor management and results will have negative effect on the organizations. This article is written by Alison Kay focusing the top management of energy sector companies’ gender preferences. According to Kay only4% of the top management in the 100 top energy...

Pakistan’s energy needs are increasing day by day. At present more than 80% of its oil is being imported from abroad. Similarly since lately it is compelled to import large quantities of natural gas as LNG, which now has an important role in the energy...

Wireless Sensor Networks (WSNs) consist of tiny and low power devices that are usually scattered in a geographically isolated areas. In WSN sensors collect data, aggregate it then send it to the base station. The sensed data is then accessible to the end user. A...

The effects which cause growth and decay of the wave are ion inertia and a pressure gradient, respectively. The pressure gradient leads to diffusion, namely, is working to smooth out the density fluctuations. If left to its own, it therefore creates a decay of the...

Introduction Electric energy is moved from generating site ( source where it is converted from other form of energy) to load (where it will be used ) through high voltage transmission lines. High voltage is used to reduce energy loss, however it produces strong electric...

Upon making a move to a WFD, you might find your energy levels begin to rise. Despite the fact this diet may inadvertently decrease your caloric intake which ordinarily would diminish energy stores, studies show that people who follow a whole food diet have higher...

Abstract—This article proposed a novel method for reconfiguration of electric energy distribution network underneath regular operating prerequisites to limit the lively losses on the community or to balance the load on the feeders. The notion at the back of reconfiguration is to understand recommended load...
