Electricity is a secondary form of energy, the primary being fossil fuels, which are used to generate it. The world’s production of electricity was twelve trillion kilowatt hours in 1997, and is expected to be close to twenty-one trillion kilowatt hours by 2020. (Fay and Golomb, 2002, 16) This is a cause of concern because based on the United States Department of Energy’s International Energy Outlook 1997 the world’s electricity generation is primarily (63%) from fossil fuels, which release large amounts of carbon dioxide into the atmosphere when burned. The unnatural amount of carbon dioxide in the atmosphere is already beginning to make some changes in our weather patterns, and predictions for the future look grim. Therefore, alternatives in electricity generation must be explored.
In order to be able to take alternative electricity generation techniques into consideration, one must know the basics about how electricity is generated. The generation of electricity is usually done in a power plant of sorts and then sent out over the power grid to homes. The employment of step up transformers that convert the twelve kilovolts normally outputted by the power plant, into four hundred kilovolts for long range transmission over high voltage transmission lines are critical to insure minimal power loss during transport. (Urone, 2001, 573) A step down transformer is then used to bring the voltage down to levels that are safe for home use, thirteen kilovolts over normal power lines, and two hundred forty volts or one hundred twenty volts (Europe and United States respectively) to the actual home.
The actual driving force behind electric powered appliances is electric current. Electricity is merely electric current used as a ...

...logy, could take off in the future. Of course, as with any type of technology, each method does have it’s own list of pros and cons. However, one thing is for sure, the current trend calls for fossil fuels to continue their domination of the energy market, which poses severe environmental risks for the future. Advancements in research and technology are making people more aware of the dangers that lie ahead. The time is now to demand a responsible energy policy from the government, in hopes of a brighter tomorrow.

Charles Robert Darwin was an English naturalist who was born in Shrewsbury, England on February 12, 1809. He was the second youngest of six children. Before Charles Darwin, there were many scientists throughout his family. His father, Dr. Robert Darwin, was a medical doctor, and his grandfather, Dr. Erasmus Darwin, was a well-known botanist. Darwin’s mother, Susannah Darwin, died when he was only eight years old. Darwin was a child that came from wealth and privilege and who loved to explore nature. In October 1825 at age sixteen, Darwin enrolled at Edinburgh University with his brother Erasmus. Two years later, Charles became a student at Christ’s College in Cambridge. His father wanted him to become a medical doctor, as he was, but since the sight of blood made Darwin nauseous, he refused. His father also proposed that he become a priest, but since Charles was far more interested in natural history, he had other ideas in mind (Dao, 2009)
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Some people will like P.F Changes just because they have always went there and do not want to go anywhere else. Another person might not care spending extra money for the same tasting food because all they care about is the friendly service. On the other hand, others might say that the food is the same so there is no need to pay more to get the same tasting food. It all

· B-phase transformer (EMTU-TT01) · Feedback electronic wattmeter · Multi-range moving-iron ammeter · Instrument voltage transformer THEORY AND INTRODUCTION ----------------------- Transformers are used all over the world to step-up and step-down electricity. The transformer is one of the most commonly used electrical devices. The reason the transformer is so popular is because they range in size from 240V to well over 240kV, stepping -up and stepping-down electricity all over the world.
Within the development of Europe, one would think that religion and politics played the key roles in shaping the regions, in which they did, but many individuals don’t realize the true impact of the role spices played in the evolution of the economy and expansion of Europe. Food alone represented a vast field of human experience and shaped peoples’ beliefs and values, aesthetics and most importantly their social attitudes toward one another. Spices contributed to these attitudes, providing a potential window for the individual to change their understanding of the political and social life of certain cultures and nations. The main question that the author, Paul Freedman poses within the text is, why did the Europeans and the Romans before them, maintain such a high demand for spices for almost a millennium?

Environmental science refers to the study of the effects that occur through natural and unnatural processes. The study involves the interactions of the Earth’s physical components that take place on the environment. Notably, the natural environment consists of all existing and non-existing things that exist on the planet. Full ecological systems that operate as natural practices without requiring the intervention of human beings are also included in the environment. Furthermore, physical units such as animals, vegetation, rocks, microorganisms, natural phenomena, and atmosphere usually occur within the boundaries of the environment (Altman and Wohlwill 113). Although the environment embraces natural resources and physical phenomena that need clear limits, it is worth noting that renewable and non-renewable energy resource is an environmental science topic that should receive top priority next year due to various reasons.
