Chapter 5 Hybridization of Wind With Solar Using Cuk and Sepic Converters This chapter presents a hybrid model of solar and wind energy. This gives the hybridization of wind with solar using the CUK and SEPIC converters. In this model the solar PV panel source is connected to the CUK converter and correspondingly the wind turbine source is given to the SEPIC converter. Solar energy and wind energy are the two renewable energy sources most common in use. Hybridizing solar and wind power sources…

“Waste: damaged, defective, or superfluous material produced by a manufacturing process…” (Merriam-Webster, Waste). Using this above definition, it is possible to break into the sub-branch known as electronic waste or E-waste. Due to the current large consumerism culture, many first world countries find themselves producing an unstable amount of E-waste from the constant “upgrading” or destruction of older electronics. Further in this paper, examples of how this waste is dealt with shall be…

Unfortunately, Tar Creek was added to the National Priorities list in 1983 making it officially a Superfund site ("Tar Creek," 2014.) It contains 40 square miles of waistline. It is referred to as the “Superfund Site” because Congress donated an enormous sum of money to support it. At the same time, oil and mining companies were taxed in order to support this fund. The fund was established in the early 80’s to support sites which have experienced environmental disaster. According to the…

One of the alternative plan is replacing coal-fired energy to solar energy in the industrial factories, in order to reduce the carbon dioxide (CO2), sulfur dioxide (SO2) and the nitrogen oxides (NOx). As most of scientists mentioned, the CO2 is one of the major greenhouse gas that causes the global warming; SO2 and NOx have link to several respiratory illnesses. In order to decrease the temperature globally and the cases of respiratory illnesses, the reduction of CO2, SO2 and NOx are the goals…

The Coal Ash Spill of 2008 On the Sunday before Christmas my Great Aunt, Janice James, did not suspect her and the lives of her family would change forever. I am forever grateful to still have her around to gain more insight into the traumatic event, that was not all included in the national news stories. If you just looked out Janice James ' back window you would know exactly why she and her husband, Perry James, chose to live on Lakeshore Drive, it was stunning! The Emory River widens as it…

People have been finding, and using sources of energy since the beginning of mankind. Whether it is fire to cook, use streams and rivers to ride a canoe, to help grind corn, or coal to power trains across the world, humans have always relied on the valuable riches that the earth produces to survive However, most of the energy that is currently being used is nonrenewable, which means that it will not replenish as quickly as it is being consumed. An example of a nonrenewable resource currently…

Municipalities in the USA and indeed around the World are generating growing numbers of plastic waste than ever before and the facts are that only a small percentage of it is recycled. In many developing countries plastics and other byproducts litter streets, drains, rivers and much of that ends up in the oceans. In the USA, the EPA estimates that the municipal solid waste stream contains more than 12 percent of plastic. This figure has grown consistently over the past fifty years, from one…

Protein is the building blocks of the muscles, there have lots of different kinds of protein supplements such as protein bar, protein powder, protein pill that had lots of levels with it and protein food. Although some sports nutritionists disagree, protein supplements are dangerous because they can lead to nutritional deficiencies, disease, and, in some cases, death also contain a lot of additives, sugar and too much protein, but natural protein provides immune system defense for the body and…

The Democratic Republic of the Congo is a land of resources that many have taken advantage of. Because of its remote location and foreign mining companies the people of the congo are very poor. The vast resources of the Democratic Republic of the Congo have major impacts on global societies all around the world. The Democratic Republic of Congo or simply called Congo is located in south central Africa between Tanzania and Gabon. The Congo is made up of a variety of different landscapes…

Working in the electronics retail space for over half a decade, computers can get updated and replaced very quickly. Commonly you can have several new models release shortly after the previous one, which can mind blowing. What happens to those aged computers once their owner deems such equipment obsolete? After doing a great deal of research, it turns out most of those computers make their way into local landfills and that in itself has become a major environmental issue. Below are a few of the…
