...Enron: The Smartest Guys in the Room This documentary explores the fall of the Enron Corporation. This is one of the most shocking modern corporate corruptions. The company is linked with several illegal schemes including instigating the California energy crisis as a way to drive up utility prices at the expense of the average American citizen. This was one of the largest business scandals in the history of America. The film examines Enron and how the criminal trials are for several of the company’s top executives. It explains the involvement of the Enron traders in the California electricity crisis. This organization started out as an ethically company but over time greet and performance was the most important no matter what happened. Enron’s company motto is “Ask Why” which is interesting because in the end all the employees are out of their 401 (k) as they file bankruptcy. Jeffrey Skilling was the captain of the ship. All this avaricious man desired was performance and to see how high the stock can go. When the stock market crashed there were a few questions why Enron’s stock kept climbing. Only after one dove into it did they start to undercover what was really going on with these invisible numbers that have no capital to back it up. At what point could this unethical situation be fixed is a good question. This scheme was like a tumble weed that kept getting bigger and bigger. In the year 200 Enron ran out of ways to show they were actually making money. The traders exported...

...of the project is to reduce the global energy crisis, using manpower. The world is in a very critical situation in the sector of energy. All the natural resources are limited, and they are running on. That’s why everyone is searching for new sources of energy. We will now discuss on only electrical energy. We know that energy can’t be produced. It can only be transformed form one kind to another. The cheapest and the most available source of energy is the sun. We can use the solar radiation, which is transformed in to electrical energy directly using PV cells. Now, to solve the electric energy crisis, we need to do a few things. * Increase the production * Decrease use, specially misuses * Reduce dependency on bio energy We will try to work on all the solutions altogether to solve the energy crisis in our project. The main idea of the project is consumers of electricity will turn into the producers of electricity. Every house will turn into a mini power plant using PV panel. It will produce electricity for that house, and whatever will be left after using in the house will be supplied in the national power grid. Government will pay the owner of the house, as well as the owner of that Mini Power Plant. The power meter will run in the opposite direction, and the producers will get cash payment from the government. Where to work: * We can make the model more effective. * The way of supplying the electricity to the national grid. * We can work on making...

...A simple definition of PV system is converting the light coming from the sun to useful electricity. In the case of LAWANG BATO NATIONAL HIGH SCHOOL, their PV system supplies the School library and T.L.E. room, wherein the reality this places is not commonly used by the students. As a student of Electrical Engineering and knowledgeable on this matter, I suggest that instead of supplying those places why not give the free electricity to the rooms used by the majority of the students of LBNHS. As I also recall waste of electricity encounter in weekends, I suggest to use that free electricity in some places like school’s hallways or for school’s lamp posts at night. On the other hand, I have learned a lot regarding this topic when we visited LBNHS. We are all aware about the issue of Electricity price hike. And I see one solution to solve this issue, let’s use renewable energy, it is free and efficient if we use and install it properly. Instead of wasting our time complaining to the government, why not think solutions that may help everyone and solve this crisis. Be educated on this matter. It will start on us, LBNHS is now using PV system, and I hope in the near future our city will develop and help every school in Valenzuela City to provide and encourage them to use renewable energy or PV system. No more complain let us do something to develop our City/Country. Be Eco-friendly. Use renewable energy. BSEE...

...Electricity has occupied in every corners of our lives. It can be clearly seen that cooking, working and entertaining directly or indirectly involve using electricity. People are slowly turning from fire as the source of heat to electric device that has capability to produce heat. Nevertheless, the growth of using electricity has pushed the world into energy crisis where demand is surpassing supply. In order to solve the issue, people must cut short electricity use and increase power input. It means that devices should be off when they are not in use, replace obsolete bulbs with energy efficient bulbs and at the same time build more energy harvest systems to enhance electricity production. Electrical energy can be produced by renewable sources and non-renewable sources of energy. With development in the technological field, renewable resources like water, solar, and wind current are preferred to produce electricity in order to replace fossil fuel which would not last very long. In fact, natural resources can produce multi-folds of electricity without being eradicated. However, this essay is comparing solar panel to wind turbine. Their major differences are location, method and efficiency. Initially, the difference of both solar panel and wind turbine is method of generating electricity. Since the solar panel has defined as an object that absorbed the sunlight and turns it into electricity. The method to generate electricity by solar panel is complex. Firstly, after the sunlight...

...value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source. Variable power supplies are common laboratory and service shop test equipment, allowing the output voltage to be adjusted over a range. Generally, a power outage can be identified as a power cut, power failure or blackout. This can be addressed as loss of electricity power to a specific area. Nevertheless, there are different causes of power failure in electricity which can easily cause damages to human and business operations. It is fairly settled in the literature that infrastructure plays a critical and positive role in economic development. Infrastructure interacts with the economy through multiple and complex processes. It represents an intermediate input to production, and thus changes in infrastructure quality and quantity affect the profitability of production, and invariably the levels of income, output and employment. Moreover, infrastructure services raise the productivity of other factors of production. Currently in Nigeria, lack of electricity supply is one of major infrastructure problem affecting the business sector. The typical Nigerian firm experiences power failure or voltage fluctuations about seven times per week, each lasting for about two hours, without the benefit of prior warning which may likely cause damages such as spoiled materials, lost output, damaged electronic electronic equipment, restarting cost operations and...

...pursue my engineering in electrical and electronics from VIT Vellore, one of the leading engineering institutions in India. During engineering, I pursued my internship at BSES Rajdhani, New Delhi’s apex power management authority. Here I worked on the Techno-management concept of Power Trading along with Indian Electricity Act and financial model used in power trading with the Power Procurement Team. It gave me deep insight into how a power trading market operates and how to use it to solve the power crisis in Delhi. Power trading was in its evolutionary phase and I used the knowledge gained from it for my Final Year Project’s financial modeling. I undertook Reactive Power Management & Trading Model Design as my topic of final year project under Mr S P Sabberwal (Former Professor at University of Manchester, U.K and Indian Institute of Technology, Delhi). It was again a techno-management study aimed to understand various complex workings and issues associated with reactive power management in the Indian electricity market and arrive at a framework to address them. A sample framework for reactive power management, which would be especially for Indian electricity market structure, was suggested and its feasibility tested through simulation of bidding models in MATLAB. We did case studies on the New York Independent System Operator (NYISO) Voltage...

...- The implementation of the process was done so quickly, that the top managers could not trainother managers to use the new system. And they could not introduce the new system in a step bystep format so they can be more aware day by day on what is going to be changing in the future.Here are the changes that can be recommended for the new system:- Specify the different kind of costs (fixed and variable), so that managers can have an idea of thedifferences and variations of each type of costs.- Implement the proper training for the managers, so that they do not make any mistakes which cancreate problems for others.- Elaborate the correct verification of the data so it does not create differences of opinions or mistakes from period to period. 4. The first issue was about how to evaluate managers’ performances in situations where the numbers were distorted by uncontrollable factors. So Rob Cushman could try to dothe following:- Call some energy companies and ask them to diagnose the transformer problem further and figureout if there any other ways to fix the problem permanently.- Have some back up electrical units, such as generators, just in case the power failure continues toexist.- See if there is a pattern in the power failures. If there is, try to set a schedule around the power cutand work as fast an efficient as possible while power is still available.The second was an issue as to whether to increase the proportion of total compensationthat was linked to individual performance...

...Electricity is produced in different ways from different sources. The most common sources are friction (static), heat (thermocouple), light (photo cell or solar cell), pressure (crystals), magnetism (generators) and chemical action (battery). 1. Static electricity is produced by friction. In friction, electrons in an insulator can be separated by rubbing to produce opposite charges that remain in the dielectric. 2. Heat energy is converted into electrical energy through the use of a device called thermocouple. It is a device consisting of two dissimilar metal wires twisted together at one end but open at the opposite end. When the joined end is heated, it produces a low DC voltage at the open end. The voltage produced by this device is directly proportional to the temperature of the metal wires. To produce a higher voltage, a number of thermocouples may be joined together. 3. Photoelectric matter. Some materials are photoelectric, which means that they can emit electrons when light strikes the surface. A device called photovoltaic cell or photo cell is made of a vacuum tube with two electrodes. One electrode is coated with sensitive materials such as cesium or selenium which give off electrons when illuminated. These electrons strike the other electrode which in turn, collects the electrons. If the tube is combined with a fixed voltage source, there will be electron flow in the circuit and this will activate photoelectric devices such as television cameral tubes, phototransistors...

It will also evaluate how businesses use the Internet to their advantage for communicating with employees, working with other businesses and working with ecommerce businesses. What Is The Buzz On Smart Grids? The Smart grid is a class of technology that people are using to bring electricity delivery systems to the 21st century using computer based remote control and automation. Two way communication technology and computer processing make it possible and has been used by other business for years. The “grid” is the network that carries the electricity from the plant to the consumer. The grid is made up of transformers, substations, wires, switches and more. The “smart” entity is pretty much the same as the new “smart phones” and it basically saying that the grid is computerized. It includes a 2-way digital communication technological device. (Energy.gov, n.d.) Smart grids differ from the current electricity infrastructure because of the way the electricity is delivered to the consumer. The current grid does not explain how the power is distributed or used. The smart grid was developed to digitally save the consumer money by increasing ways to save energy, reducing cost and increasing reliability. With these new smart grids the energy company will be able to send information from the electrical provider to the consumer and back to the grid allowing...

...three dimensions, which he used to control the terrifying vivid nightmares he suffered from as a child. In 1882 Tesla began working for Thomas Edison. In 1885 Nicola Tesla claimed that he can fix the problem that Edison was having with his DC generators and motors. Edison offered him $50000 if he get problem solved. And when he did and asked for the money, Edison laughed him off and said “Tesla, you don’t understand our American humor.” Tesla resigned then and there. Nikola Tesla was best known for his design of the modern alternating current (AC) electricity supply system. He started working on AC after falling out with Edison. This ignited a feud with Edison, who at that time was trying to sell the world his DC system. Edison DC system required power plant every square mile and couldn’t transmit electricity very far while AC used thinner wires, had higher voltage, and could transmit electricity over long distances. Electricity system that powers every home on the planet to this day. But who do we thank for this invention that ushered humanity into a second industrial revolution, who do we call the father of electric age? Thomas Edison. Why? Because he invented light bulb....

...#15 Aircraft Hydraulic Systems Managers should always make sure these systems are always properly serviced and bleed after any maintenance is done to prevent air in the system. Air in these systems may not seem like a big deal, but air is compressible and when entering components, they are weak. The force of air onto a spoiler surface pushes down due to air in a spoiler actuator. Pilots should watch for sudden system pressure and quantity drops, which could be the result in several things such as air that finished its way through the system or a broken component. Air in the lines vibrates and can cause the line to rupture. To prevent this low-pressure system bleed is preferred, exercising all subsystems to push the air out slowly and safely for both personnel and the aircraft. Another key fault to watch for is system demand loads. Both pilots and maintenance alike will power up the hydraulic systems and try to operate every flight control system at once over loading the work load of the pumps causing them to either shell out, crack or the spline shaft of the pump strips out (which is what is supposed to happen to prevent loss of the system). There are all kinds of emergency procedures for these hydraulic systems, some are electrically controlled, some are pneumatically controlled, and some systems have a redundancy system (two systems operating the same component). Electric one is just a switch opening up reserved pressure in an accumulator to operating a sub system...
