The location where the technology is installed plays a major role in providing the energy resource for renewable energy technologies. Solar installations close to the equator have more energy production capability. Wind energy variations are more extreme, windiest regions are favorable to install wind turbines that generates significant amount of electrical energy such as New Zealand and United Kingdom (Freris and Infield, 2008). Table 3.1 shows the main parameters related to renewable energy technologies and conventional plant. It also indicates the three major components of energy generation cost which are: (1) the cost of the plant, land acquisition, grid connection and initial finance cost, (2) operation and maintenance cost (OM) and finally fuel cost. From the table it is noticeable that most of the renewable energy technologies have zero fuel cost and it varies in conventional plant. Table 3.1: Comparison of cost and performance data for renewable energy and conventional plant (Freris and Infield, 2008) Levelized cost method is the main traditional approach used to compare cost generating electricity from various energy technologies. The levelized cost of energy technologies is measured as it is shown in Equation 3.1: LOCE = (Eq. 3.1) The LCOE method is concept from reality and is used as a ranking tool to measure the cost-effectiveness of various energy generation technologies. Where CF is the capacity factor; OC is the overnight construction cost; CRF is the capital recovery factor; OMC is the series of annualized operation and maintenance costs; FC is the series of annualized fuel costs; r is the discount rate and T is the economic life of the plant. 3.1.1 Cost of photovoltaic Cells Solar radiation is a finite and free source of energy but despite that, there is cost for utilizing this form of energy. The calculation of the cost of solar energy can be made in the following manner. Assuming the solar system would have a specific lifetime of T years at initial cost of C0 Dollar. The amount of energy the system can generate during the lifetime of the system is Q (Goswami et al., 2000). The unite cost of energy, neglecting the interest charges, is equal to the cost of the installation divided by the total energy generated during the lifetime as it is shown in Equations 3.2: Cs = (Eq. 3.2) For example if the solar energy collector cost $200/m2 , has an expected life of 20 years, and is installed in a location where the mean annual horizontal surface irradiance is 300 W/m2 averaged over 24 hours, the cost of solar energy Cs will be equal to: = = $0.00380/Kw.hr However it is clear that no solar energy collector can perform at 100% efficiency. According to thermodynamic laws only a fraction of incident energy can be transformed into useful heat. Assuming the efficiency of the collector Ãâ Ã
¾c is 40 percent, the cost of solar will be given by Equation 3.2: Cs = = $0.00951/Kw.hr (Eq. 3.3) The efficiency of photovoltaic device plays a major role in the cost of the technology as we notice from the previous equation along with the optic of the device. The price of photovoltaic materials is usually expressed on a per-unit-area basis but the units are often sold based on cost per watt that is generated under peak solar illumination conditions. Equation 3.4 is used to convert the cost per square meter to cost per watt for photovoltaic technologies: $/WP = (Eq. 3.4) The return on investment made for specific equipment or material used for the photovoltaic system also is estimated. The payback time of PV unite of cost $/m2, is associated with the efficiency of the system, the installation location and the price of at which electricity generated is sold on the market $/kWh. Equation 3.5 is used to estimate the payback time which is: Payback time = (Eq. 3.5) The generate a significant quantity of energy in commercial application, several elements should be mainly considered such as the average illumination, cost of land, batteries, support structure and the life time of the PV unite. Balance of system (BOS) cost must be considered and it includes the mounting, wiring, operation cost and maintenance cost. The cost of electricity generated by solar cells can be calculated using Equation 3.6a and Figure 3.1 illustrate breakdown of the cost in PV system. Figure 3.1: PV Solar System Cost Breakdown (Source: the Rocky Mountain Institute) (Eq. 3.6a) Inserting the relevant terms, in Equation 3.6a and it becomes: = (Eq. 3.6b) The amortization rate is estimated from the real discount rate of i, and a PV lifetime, N, as shown in Equation 3.7: Amortization = (Eq. 3.7) The global annual production of solar energy technologies is estimated to be at approximately 12,400 MW in year 2007. Annual growth of PV production remains to be at 40-50% and according to Earth Policy Institute, the photovoltaic industry has grown by an average of 48% each year since 2002. This rapid growth of PV production made the solar energy became the world fastest-growing renewable energy resource (Henry and Healey, 2007). The wide variety of photovoltaic panelââ¬â¢s technologies competing in different energy markets was a major role in the rapid growth of solar energy technologies in a short period of time. For instance, largeââ¬âscale photovoltaic panels and concentrated solar power technologies are competing with other technologies that seek to serve the centralized grid. Whereby on the other hand, small-scale solar systems compete with other types of technologies such as; diesel generation sets and off-grid wind turbines (Timilsinaa et al., 2012). Along with the variety of PV technologies, with the advancement of science and technology sector, the efficiency and power generation capacity of solar technologies have been improved to generate electricity that can compete with the conventional sources power plants. Photovoltaic technologies have been experiencing, the price of PV models haven been steadily decreasing during the past few decades. A lot of elements such as; Technology improvement using lower cost feedstockââ¬â¢s, efficiency increases, thinner solar cells, reduction in technical losses and increased manufacturing through had played a major role in decreasing the cost of PV modules throughout the years (Sioshansi, 2011). Figure 3.2 shows the declination in photovoltaic panelââ¬â¢s price per watt from 1978 until 2012. Figure 3.2: Historical photovoltaic module price per watt from 1978-2012 (Source: Navigant Consulting, 2008) From the Figure3.2, the price of PV modules were at it maximum in 1976 with 75$ per watt but in year 1978 the price drop to reach almost 55$ per watt. PV modules price kept decrease with the time passage and between 1986 and 1988 the price of PV module reached below the 10$ per watt. The declination of PV modules cost did not stop and between years 2010 and 2012 the price reached the lowest rate which was 1$ per watt. Photovoltaic technology system have no moving parts, this property reduces the cost of PV modules significantly along with the minimum operation and maintenance costs (mainly to remove the dirt and dust off the module) which is around 0.5% of the capital investment per year. The cost of PV unit presently is 60% of the total cost of PV system cost and the remaining 40% is covered by the structures, inverters and cabling costs (Aswathanarayana et al., 2010).

Coconut Oil
Coconut oil is a popular nutritional oil derived from the flesh of matured coconuts. Coconuts have long been a primary source of food throughout the tropics and their many industrial and cosmetic applications have made them a valuable commodity. Coconut oil is heat stable, making it suitable for cooking at high temperatures, itââ¬â¢s slow to oxidize, resists rancidity and has a shelf life of approximately two years or more (virgin coco creme created through a wet-milling process has an indefinite shelf life). Coconut oilââ¬â¢s compositionCoconuts have a variety of health benefits due to their fibre and nutritional content, but itââ¬â¢s the oil that makes them a remarkable source of food and medicine. Coconut oil has definitely earned its reputation as the healthiest oil in the world despite the fact that its high saturated fat content was once falsely claimed to be unhealthy. What makes coconut oil different? Oils and fats are composed of molecules known as fatty acids. They are classified either according to saturation or based on molecular length and size of the carbon chain within each fatty acid.Monounsaturated fats and polyunsaturated fats are an example of the first class. The second classification is based on molecular size or length of the fatty acidââ¬â¢s carbon chain. Long chains of carbon atoms consist of each fatty acid with an attached hydrogen atom. There are short chain fatty acids known as SCFA, medium chain fatty acids (MCFA) such as coconut oil and long chain fatty acids (LCFA). Whether unsaturated or saturated, the majority of fats and oils in our diet are composed of long chain fatty acids.In fact, a majority of the fatty acids commonly consumed are LCFA. Coconut oil is predominantly medium-chain fatty acid (MCFA) and the effects of the MCFA in coconut oil are distinctly different from the LCFA found in other foods. In fact, the saturated and unsaturated fat in milk, eggs, meat and even in plants and most vegetable oils are made of LCFA. Why is this relevant? Itââ¬â¢s important because our bodies respond and metabolize each fatty acid differently. The MCFA found in coconut oil makes it special because these fatty acids donââ¬â¢t have a negative effect on cholesterol.In fact, theyââ¬â¢re known to lower the risk of heart disease and atherosclerosis. There are only few dietary sources of MCFA, and one of the best sources by far is coconut oil. The liver and gall bladder donââ¬â¢t need to digest and emulsify MCFA, resulting in instant energy, increased metabolic rate and subsequently greater heat production and increased circulation. Anyone with an impaired fat digestion or removed gallbladder will benefit from coconut oil as this oil isà easily digested. Lauric acid Many of coconut oilââ¬â¢s health benefits are attributed to its lauric acid.Lauric acid in the body is converted into monolaurin, a compound thatââ¬â¢s highly toxic to viruses, bacteria, fungi and other microorganisms because of its ability to disrupt their lipid membranes and virtually destroy them. Monolaurin is effective for treating candida albicans, fungal infections and athleteââ¬â¢s foot. It also targets bacterial infections and viruses like measles, influenza, hepatitis C and even HIVââ¬âresearchers from the Philippines are studying the effectiveness of lauric acid against HIV/AIDS due to its strong antiviral properties.Moreover, lauric acid is non-toxic, making it a better alternative to modern drugs prescribed for viruses, fungal and bacterial infections. Without lauric acid, monolaurin cannot be produced by the body. Breast milk is the only other source of lauric acid, which could explain the lower incidence of infections among breast-fed infants. Regular consumption of coconut oil has also been found to boost immunity and reduce the frequency of sickness. The health benefits of coconut oilHair careà ââ¬â The unique fatty acids in coconut oil have a small molecular structure and pas s freely into the hairââ¬â¢s cell membrane, allowing the oil to penetrate the hairââ¬â¢s shaft, which brings out the deep conditioning from within as compared to other conditioners that work from the outside in. Massaging the oil into the scalp can offer relief from dandruff. Dandruff is caused by dry skin or an internal fungal condition that reached the scalp. With regular use, coconut oil can kill the fungus and eliminate dandruff issues. Forà deep hair conditioning, a teaspoon or two on damp hair left for as long as possible can give a nice shine.Leave it on overnight and see startling results. Skin careà ââ¬â Coconut oil is an excellent skin conditioner that contains medium-chain triglycerides, naturally occurring fats which deeply penetrate, moisturize and act as a protective barrier against environmental and free radical damage. The oil also provides sun protection by screening 20 per cent of ultraviolet exposure. Coconut oil is rich in antioxidants and the natur al microbial and antibacterial agents caphrylic and capric acids. Its ability to smooth the skin while infusing with antioxidants make it a perfect anti-aging moisturizer.Moreover, it contains vitamin E, another antioxidant popular for hastening the recovery of skin abrasions, burns and other trauma. Weight lossà ââ¬â Medium-chain fatty acids found in coconut oil can speed up metabolism faster than long-chain fatty acids because they are easily digested and converted into energy. In fact, aà study reportedà medium-chain fatty acids to be three times more effective in raising metabolism than long-chain fatty acids, leading researchers to conclude that effective weight loss can be achieved by replacing long-chain fatty acids with medium-chain fatty acids.Natural remedy for pneumoniaà ââ¬â The American College of Chest Physicians found that coconut oil offers pneumonia patients faster and more complete relief from symptoms. This could be a welcome development for many a s this means a shortened hospital stay, lower medical expenses and lower exposure for the patient to a hospital environment. Moreover, itââ¬â¢s anà inexpensive addition to traditional antibioticsà and has no known side effects.Lowers risk of diabetes, heart disease and improves cholesterol levelsà ââ¬â In a study of 20 to 40-year-old women, half were instructed to take a 30 ml soybean oil supplement while the other half were instructed to take a 30 ml coconut oil supplement while maintaining a moderate exercise routine over a 12-week period. Results showed that although both groups of women had a decrease in body mass index (BMI), only the women who were taking coconut oil showed a notable decrease in waist circumference, significantly lowering the risk of conditions like type II diabetes and heart disease.Furthermore, the study also showed that the subjects who experienced an improvement in their cholesterol profile along with higher HDL levels and higher HDL to LDL ra tio were the ones taking coconut oil. Those taking soybean oil did not receive theà same benefitsà but reflected a higher total cholesterol as well as higher LDL cholesterol lower, lower HDL cholesterol and a lower HDL to LDL ratio. Assists in bone health and chronic fatigueà ââ¬â Research has found coconut oil to help prevent osteoporosis because it helps in the nutrient absorption of minerals such as calcium and magnesium ââ¬â important minerals that fight steoporosis. Moreover, the medium-chain fatty acids in coconut oilà produce energyà rather than body fat, thereby improving metabolism and preventing fatigue. The oil has also been shown to destroy organisms in the body that sap its strength and contribute to the condition of fatigue. Alzheimerââ¬â¢s Diseaseà ââ¬â Dr. Mary Newport, after failing to get treatment for her husbandââ¬â¢s dementia, discovered that coconut oil contained natural medium-chain triglyceride (MCT). The same substance was used in a drug trial her husband failed to qualify for.So, she gave her husband 1 tbsp. of coconut oil twice a day for a month and a half and saw him recover almost completely. Other benefits: â⬠¢ Protects against cancer, HIV and other infectious diseases â⬠¢ Kills bacteria and parasites like tapeworm and liver flukes â⬠¢ Eases acid reflux and aids in proper bowel function â⬠¢ Lowers incidence of hemorrhoids â⬠¢ Heals and relieves intestinal problems â⬠¢ Soothes earaches â⬠¢ Deals with symptoms connected with prostate enlargement â⬠¢ Strengthens the liver and protects against degeneration Reduces incidence of epileptic seizures â⬠¢ Reduces joint and muscle inflammation â⬠¢ Eases neuropathies and itching from diabetes. How much oil should be taken? According to researchers, an adult should consume around 3 1/2 tbsp. of coconut oil daily: an amount equal to the MCFA a nursing infant would receive in one day. The benefits of coconut oil are derived fr om the nutritional value of medium-chain fatty acids (MCFAââ¬â¢s), and the best comparison in nature as to the percentage of MCFA consumed in a diet is in human breast milk.For those who arenââ¬â¢t used to having coconut oil in their diet, itââ¬â¢s best to start out with a smaller amount and see how the body reacts before following the recommended amount. Does coconut oil have any adverse side effects? Coconut oil has no known side effects. However, if youââ¬â¢re used to a low-fat diet, a common adverse reaction would be diarrhea. Itââ¬â¢s probably not advisable to start with a large amount right away. Spreading the recommended amount over the course of one day and building up to a larger dose can help to avoid unwanted effects.In coconut-producing countries, itââ¬â¢s considered beneficial for pregnant and lactating women to enjoy coconut oil; Westerners used to a low-fat diet, however, are cautioned not to experiment with coconut oil while pregnant if the body is not used to it. If youââ¬â¢ve been consuming coconut oil regularly with no adverse reactions, thereââ¬â¢s no reason to discontinue consumption.

The History of the English Language
The story of Englishââ¬âfrom its start in a jumble of West Germanic dialects to its role today as a global languageââ¬âis both fascinating and complex. This timeline offers a glimpse at some of the key events that helped to shape the English language over the past 1,500 years. To learn more about the ways that English evolved in Britain and then spread around the world, check out The History of English in 10 Minutes, an amusing video produced by the Open University. The Prehistory of English The ultimate origins of English lie in Indo-European, a family of languages consisting of most of the languages of Europe as well as those of Iran, the Indian subcontinent, and other parts of Asia. Because little is known about ancient Indo-European (which may have been spoken as long ago as 3,000 B.C.), well begin our survey in Britain in the first century A.D. 43ââ¬âThe Romans invade Britain, beginning 400 years of control over much of the island.410ââ¬âThe Goths (speakers of a now extinct East Germanic language) sack Rome. The first Germanic tribes arrive in Britain.Early 5th centuryââ¬âWith the collapse of the empire, Romans withdraw from Britain. Britons are attacked by the Picts and by Scots from Ireland. Angles, Saxons, and other German settlers arrive in Britain to assist the Britons and claim territory.5th-6th centuriesââ¬âGermanic peoples (Angles, Saxons, Jutes, Frisians) speaking West Germanic dialects settle most of Britain. Celts retreat to distant areas of Britain: Ireland, Scotland, Wales. 500-1100: The Old English (or Anglo-Saxon) Period The conquest of the Celtic population in Britain by speakers of West Germanic dialects (primarily Angles, Saxons, and Jutes) eventually determined many of the essential characteristics of the English language. (The Celtic influence on English survives for the most part only in place namesââ¬âLondon, Dover, Avon, York.) Over time the dialects of the various invaders merged, giving rise to what we now call Old English. Late 6th centuryââ¬âEthelbert, the King of Kent, is baptized. He is the first English king to convert to Christianity.7th centuryââ¬âRise of the Saxon kingdom of Wessex; the Saxon kingdoms of Essex and Middlesex; the Angle kingdoms of Mercia, East Anglia, and Northumbria. St. Augustine and Irish missionaries convert Anglo-Saxons to Christianity, introducing new religious words borrowed from Latin and Greek. Latin speakers begin referring to the country as Anglia and later as Englaland.673ââ¬âBirth of the Venerable Bede, the monk who composed (in Latin) The Ecclesiastical History of the English People (c. 731), a key source of information about Anglo Saxon settlement.700ââ¬âApproximate date of the earliest manuscript records of Old English.Late 8th centuryââ¬âScandinavians begin to settle in Britain and Ireland; Danes settle in parts of Ireland.Early 9th centuryââ¬âEgbert of Wessex incorporates Cornwall into his kingdom and is recognized as overlord of the seve n kingdoms of the Angles and Saxons (the Heptarchy): England begins to emerge.Mid 9th centuryââ¬âDanes raid England, occupy Northumbria, and establish a kingdom at York.
