Download file to see previous pages For years, photovoltaic cells, otherwise known as solar panels, have been used in such various items as spaceships and on the roofs of houses (Lovich and Ennan 2011, 982). Countless billions of batteries, for example, have gone unneeded as a result of solar technology being used in many calculators. Quite simply, solar energy harnesses the power of the sun. When the rays from the sun hit the photovoltaic cells, there is a near instant reaction that free electrons from their atoms, and this action results in electricity being generated (Gratzel 2007, 998). This means that there is no need for any other type of energy source when solar energy is put into place properly. In recent years, solar thermal power plants have begun to be built. This provides energy on a massive scale, using the heat from the sun to boil water. This is then used to create a steam turbine effect that can supply electricity for thousands of people in the vicinity, similar to what coal and nuclear power plants do, but without the pollution and other harmful effects caused to the environment (Grazel 2007, 999). As one can already determine, solar energy has numerous uses and is referred to as an inexhaustible fuel source. While we cannot be sure when other forms of energy will be depleted, we know that as long as the earth is in existence, we will have the sun to provide us with energy. As such, it is important to continue to develop ways to utilize solar energy on an even more massive scale in order to conserve the precious resources now being used up way too quickly. This paper will take a look at some of the various ways that solar energy can accomplish just that in the coming years. Analysis Fossil fuels have a negative impact on the environment, and countries around the world are now implementing policies that require the implementation of alternative energy sources that are friendlier to the environment (Solang et. al. 2011, 2149). This is primarily due to the increased demand for energy globally. Government leaders and concerned citizens realize that they can no longer supplement this hunger for energy with fossil fuels. Out of this has arisen a renewed interest in solar energy. Solang, et al, (2011) notes that, “Solar energy is one of the best renewable energy sources with the least negative impact on the environment” (2150). The authors note that globally countries are not developing solar energy policies that are aimed at conserving resources and further reducing our dependence on fossil fuel as a primary means of energy production. In recent years, solar energy capacity has increased an average of just under 50% per year globally (Solang, et al, 2011, 2152). This is the result of many successful incentive programs implemented by various countries. These policies are encouraging countries and private citizens to develop and utilize renewable energy technologies, of which solar energy in a primary player. Through the encouragement of developing further uses for solar energy, many interesting techniques and innovations have been discovered. Among these is the process of desalination, which is proving more successful than ever envisioned and could prove to be a great way to conserve even more natural resources moving forward. Globally, the demand for potable water is increasingly exponentially. This is particularly true in less developed areas of the world and in place where freshwater supplies are limited or ...Download file to see next pages Read More

Global Culture on Fast Track

Lifestyles are changing fast to invite international practices. Youths in large numbers are instrumental to change to live in a free environment. They are resisting ‘no change’ attitude and fighting for the new environment where they can express freely what think right to make a modern culture. The change is undergoing automatically and being accepted by most of the resistant quarters.

Globalization does not create a common culture, values, attitude or beliefs as mentioned above. It gives way to a single arena in which people of different cultures interact and present their values for comparisons, analysis, acceptance or rejection on certain standard yardsticks. This is the internationalist version of global...

Investigating the Viscosity of Vegetable Oil

Vegetable oils are essentially esters of glycerol and fatty acids derived from plant and animal sources. Due to the difference in the composition of fatty acids in different types of oils, there are differences in their viscosities also. Most vegetable oils are liquid at ambient temperatures; and are also more viscous than aqueous solutions (Lewis: 132).
In several food processing operations, it is essential to determine the viscosity of the fluid being processed so that the most suitable equipment can be selected. The viscosity may change considerably during some operations such as heating, cooling, homogenization, concentration and industrial fermentations by molds. When planning these processes, these viscosity changes nee...

Global Warming and Food Production

The carbon fertilization effect of increased carbon dioxide concentration in the atmosphere has an impact on plant growth, which benefits plant growth by facilitating photosynthesis, cannot balance the complex impact of increased temperatures around the world. Thus, although some regions will benefit from global warming, a total reduction in global agricultural production will result. This essay presents a discussion about the impact of global warming on agriculture and food production around the world.
Although the history of the planet earth suggests that for the last million years ice ages have been interspersed with warmer periods, evidence suggests that the average rate of global warming within the recent past has accele...

The Importance of Employee Empowerment in the Global World

Empowerment is the authority to make decisions within one’s area of operation without having to get approval; from anyone else. Here the operatives are encouraged to use their initiative to do things the way they like. To this end, the employees are given not just authority but resources as well so that they not only take decisions but implement them quickly. This empowerment means giving the employees the authority to make decisions and providing them with financial resources to implement these decisions (Koch & Godden, 1997 11).
Employee participation and empowerment participation means sharing the decision making power with the lower ranks of an organization in an appropriate manner (Lashley & McGoldrick, 199...

Oil Prices by OPEC and Market Fundamentals

Market failure is defined as the inefficient allocation of resources by the market, the free market is considered to optimally prices and resources in the production of goods and services, and this is because the price and quantity produced are determined by market forces which include the demand and the supply. The control of prices by a firm or an organization in the market results in market failure, therefore OPEC leads to market failure due to its nature in the market.

OPEC was formed in 1960 by 5 oil-producing countries which include Venezuela, Saudi Arabia, Kuwait, Iran and Iraq, The aim of this organization was to unify petroleum-producing countries in order to realize fair and stable prices of oil .other oil-pro...

The Bhopal Gas Disaster

In the incident, a toxic gas called methyl isocyanate (MIC) weighing around 42 tonnes was released into a city with a population estimated at 500,000 people. The incident was devastating: the immediate death toll was 2,259 people. Generally, it is estimated that 8,000 people died in the first two weeks and more than 8,000 died later from gas-related complications. It is believed this is the worst industrial incident of the recent past.
The Union Carbide India was a company that produced carbonyl pesticide, which is an intermediate product of methyl isocyanate. The methyl isocyanate is a toxic material but cheaper compared to other raw materials that could have been used. However, the chemical involved in this incident was a c...

The Effects of Financial Crisis on Supplier Selection Criteria of the Oil and Gas Industry Equipment Market

It is a difficult task to find those vendors who not only have the adequate quality and quantity of the needed raw materials but who also have an attitude of efficiency and display commitment to customer service (Sonmat, 2006). Further, organizations also strive to locate and select vendors who can be depended upon for long term relationship.

The number of factors or attributes desired from the vendor is vast, and different organizations and different industries place different importance on the attributes (Sonmat, 2006). Some of the vendor attributes may gain importance owing to the nature of the industry, for example, in the case of consumer perishables suppliers, like fresh vegetables or fruits, the buying firm would...

Pathophysiological Processes Involved in Type Two Diabetes

Changes in lifestyle and behavior, in particular, sedentary jobs combined with lack of exercise and an increase in disposable income combined with lower food prices, have resulted in a veritable explosion of type 2 diabetes. Left untreated, type 2 diabetes can lead to a series of complications and illnesses and a high incidence of premature morbidity. However, over-rich nutrition and the resulting obesity are not the only risk factors as there are different levels of susceptibility to type 2 diabetes in different ethnic groups.

According to statistics released by the World Health Organization (WHO), currently, 180 million people worldwide have diabetes, with 2.9 million deaths per year occurring due to complications cau...
