Experts believe that it may take so long to develop solar energy systems that alternative energy sources like solar energy will still make up less than five percent of our energy needs by the year 2030 (Lavelle, 2007).
Another big problem with changing over to solar energy is that it is very expensive. That is because to collect solar energy, you need very large collectors and a lot of land to build them on. The way solar energy systems work is that the sun's rays are collected by photovoltaic panels and they are very expensive to make (Lavelle, 2007).
One solution to that problem is using specially built mirrors instead of photovoltaic panels. However, even that solution still means that large solar energy systems need extremely large arrays of solar panels that are hundred of square feet. Right now, American companies like Pacific Gas & Electric (PG&E) are working on developing solar powered energy plants that use mirrors to concentrate sunlight and heat water. That water is used to power turbines that produce electricity the same way as old fashioned hydroelectric plants that use the energy of falling water in hydroelectric dams (Zuckerman, 2007).
Pacific Gas & Electric has started working on a big project of this kind and plans to increase the number of solar energy capture arrays by five times by using some of the deserts in the Southwest and Western states. They are also working...
Feminist Therapy From a feminist perspective, the foundations of contemporary psychology and therapy are a scandal. The origins of the contemporary therapeutic relationship are based on Freud's "talking cure" for "hysteria" -- and it is worth noting that "hysteria" was, one hundred years ago, a mysterious mental illness that mainly affected women, simply because they were women. The word "hysteria" itself derives from the Greek word for "uterus"! The illness that
Nursing is a science and an art, combining evidence-based practice with a practice based on caring, compassion, kindness, and respect. Evidence-based practice legitimizes nursing as a profession, as it eliminates guesswork during the delivery of care and ensuring a scientific foundation for clinical decisions. Nursing involves following and often developing the standards and procedures that promote both individual health and public health. As an art, however, nursing involves caring for
Political Science OSHA The Occupational Safety and Health Act (OSHAct) of 1970 was passed by Congress in order to make sure that every working person in the country had safe and healthful working circumstances and to preserve human resources. Under the OSHAct, OSHA was put into place within the Department of Labor and was sanctioned to control health and safety conditions for all employers with very few exceptions. OSHA was created in
Police Administration; Structures, Processes, And Behaviors 8th Edition The Evolution of Police Administration Over the centuries, police administration has evolved in several important respects including how police have been organized and what they considered their core strategy for providing value to the communities they serve (Perry, 2001). It is argued that the present police work is not very different from previous police work performed by the London Bobbies in 1829 and the
One of the major problems faced by Charlemagne in his efforts to extend the level of education was the fact that there were very few educated persons available to teach others. Years of neglect had left the educational field with few individuals possessing the background necessary to teach others. What little scholarship that still existed in Europe was concentrated in and around Rome and Charlemagne initiated an aggressive program to
English Structure vs. Russian Translation This report is about the structure of the English and Russian languages as they pertain to the unique skill of translation. Language translation has always been made difficult by the fact that languages are in constant flux. The English and Russian languages have had to remain current with new fads and technologies like that of the internet and computer technology. Consider that a word like 'cookie'
