Effective energy conservation and management in the building sector : the answer to the energy predicament

Modern civilization has developed principally through man's harnessing of forces. For centuries man had to rely on wind, water and animal force as principal sources of power. The advent of the industrial revolution, electrification and the development of new technologies led to the application of wood, coal, gas, petroleum, and uranium to fuel new industries, produce goods and means of transportation, and generate the electrical energy which has become such an integral part of our lives. The geometric growth in energy consumption, coupled with the world's unrestricted growth in population, has caused a disproportionate use of these limited natural resources. The resulting energy predicament could have serious consequences within the next half century unless we commit ourselves to the philosophy of effective energy conservation and management. National legislation, along with the initiative of private industry and growing interest in the private sector has played a major role in stimulating the adoption of energy-conserving laws, technologies, measures, and practices. It is a matter of serious concern in the United States, where ninety-five percent of the commercial and industrial facilities which will be standing in the year 2000 - many in need of retrofit - are currently in place. To conserve energy, it is crucial to first understand how a facility consumes energy, how its users' needs are met, and how all internal and external elements interrelate. To this purpose, the major thrust of this report will be to emphasize the need to develop an energy conservation plan that incorporates energy auditing and surveying techniques. Numerous energy-saving measures and practices will be presented ranging from simple no-cost opportunities to capital intensive investments.

China's Building of a Blue-Water Fleet

In recent years the People’s Republic of China has begun to exhibit a more aggressive naval policy as a result of its decision to switch its naval force from a primarily green-water fleet (coastal) to a blue-water fleet (expeditionary) (“China’s New,” n.d.). This decision has brought China to loggerheads not only with other local East and South Asian powers such as India and Japan, but also with the predominant blue-water power of the world, the United States, that sees its supremacy threatened (“When Grand,” n.d.). Why would China embark on a route that would pit it against the world naval superpower, the United States, which has a huge lead on China in terms of naval blue-water power? Why would China try to challenge and match the U.S. Navy’s eleven aircraft carriers (“The World’s,” n.d.)? What could compel China to embark on a plan that would so disrupt the balance of power in the waters around Asia? To fully understand the Chinese government’s decision, one must first look at Chinese import figures and Chinese trade routes.
