Electricity Generation Essay -- Energy Fossils Electical Environment P

Electricity is a secondary form of animation, the primary being fossil fuels, which are employ to generate it. The worlds production of electrical energy was twelve one thousand thousand kilowatt hours in 1997, and is expected to be close to twenty-one one million million kilowatt hours by 2020. (Fay and Golomb, 2002, 16) This is a cause of concern because based on the United States Department of Energys International Energy arithmetic mean 1997 the worlds electrical energy generation is primarily (63%) from fossil fuels, which squeeze out 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 bear 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 genera ted. The generation of electricity is usually done in a occasion plant of sorts and then sent out over the power control 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 minimum power loss during transport. (Urone, 2001, 573) A step down transformer is then employ to bring the voltage down to levels that are safe for home use, long dozen 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 crusade force behind electric powered appliances is electric current. Electricity is besides electric current used as a ... ...logy, could take transfer in the future. Of course, as with any type of technology, each method does nonplus its own list of pros and cons. However, one thing is f or sure, the current disregard 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 informed 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. List of SourcesFay A., James and Golomb S., Dan. 2002. Energy and the Environment.
