One of the main benefit of networking the businesses computers and information is that business processes are speeded up and inefficiencies are squeezed out. This is because information flows more freely. Everything happens much faster. All kinds of documents - from emails to spreadsheets and product specs - can be exchanged rapidly between networked users. In the Special Salmon case, the headquarters can update the different varieties of fish, prices for each type of fish, quantity demanded and…

Renewable power for electricity production is a largely controversial topic in Australia, with benefits and detriments ranging environmentally, politically and financially. Producing about 23 percent of the world 's energy needs, coal-burning is a cost-efficient way for Australia to create electricity, however there are negative impacts to coal-burning, such as its harmful fumes and damaging emissions. Clean alternatives to coal-power, despite being costly, already exist and are widely used…

Chernobyl Explosion 1986 On April 26, 1986, the Chernobyl nuclear power plant that was in Ukraine, which at that time was a part of the former Soviet Union, exploded causing fires and it released 5% of the radioactive reactor core into the atmosphere (Institute, 2015). This accident caused the largest uncontrolled radioactive release into the environment that was ever recorded and large amounts of radioactive materials were released into the atmosphere for about ten days (Association, 2016). The…

the water wheels and mills of the Middle Ages to the photoelectric effect in solar panels of the early 1900’s, renewable energy is constantly being renovated and improved upon. Due to fossil fuels’ negative effects on the environment and lack of supply, renewable energy should be used in substitute. When fossil fuels are burned, greenhouse gases are released into the atmosphere. Greenhouse gases trap heat around Earth’s surface making temperatures slightly warmer and changing the climate. In…

2.2.2 ECONOMIC LOAD DISPATCH The primary concern of an economic dispatch problem is to minimize the fuel cost of thermal power plants for a given load demand subject to the operating constraints of a power system. Therefore, it can be formulated mathematically with an objective function and constraints 2.2.2.1 Objective Function The primary objective of any ELD problem is to reduce the operational cost by fulfilling the load demand within limit of constraints. The various kinds of objective…

elements produced enormous sums of energy in the form of both heat and radiation; these hazardous explosions covered entire cities in an iconic mushroom smog cloud. The infamous explosive smog can be seen in Figure 1 to understand the catastrophic power of this energy release. The meticulous challenge for scientists since then has been to research how…

With growing widespread use of nuclear power, around the world and the historic nuclear disaster, of Chernobyl, still in peoples minds it begs the question of whether or not the pros outweigh the cons. Nuclear power provides 20% of the power inside the United States according to the Nuclear Energy Institute and with 104 nuclear power plants inside the US alone the security of these power plants can not be overlooked. Since 911 the security of nuclear power plants took a drastic reform as it…

Describe 5 major advantages associated with High Voltage Direct Current (HVDC) distribution systems when considered alongside alternative solutions. [5 marks] i) HVDC have lower losses when compared to the equivalent AC cable distribution. The DC power transmission lines run at losses of approximately 0.3-0.4% per 100km. Converter stations also need to be considered which have losses of around 0.6%. Overall HVDC transmission losses are nearly always lower than AC transmission. ii) HVDC can…

Building a fusion nuclear power plant is not an impossible dream. After the disaster at the Fukushima nuclear power plant in March 2011, more countries and experts have shifted their focus to conduct more research on fusion. If a fusion power plant is far more environmentally friendly compared to a conventional fission power plant, more funding should be given to the research and development of fusion technology. By examining the pros and cons of fission and fusion, fusion is superior to…
