Abstract

In this study we try to explore the concept of renewable energy in a holistic context. The main focus of the research is on renewable energy and the sources through which renewable energy can be extracted. The research also analyzes the benefits that could be attained through renewable energy and the cost incorporated while extracting renewable energy from distinct sources. Finally the research describes renewable energy implications on U.S economic growth and the reliance on foreign crude oil; in addition the analysis aim to explore the go green concept and its impact.

Introduction

The purpose of this paper is to enlighten and explore renewable energy. This paper aims to present the benefits of renewable energy; in addition, the paper focuses on the cost of renewable energy. Nevertheless, the analysis explores implications of renewable energy on U.S economic sustainability along with the importance of “go green” concept. Fossil fuels currently account for 85% of the total U.S energy supply and are the nation's main energy source for many decades. They are relatively inexpensive and readily available from many sources, both domestic and overseas. According to many climate experts, the burning of fossil fuels elevates atmospheric levels of carbon dioxide and other "greenhouse gases," exacerbating problems with global warming.

As of 2007, many energy policy makers are asserting that the U.S. must wean itself from fossil fuel consumption. Calls to increase reliance on "renewables" have proven controversial, however. Some people question the environmental benefits of such power sources, and claim that there is nothing wrong with the U.S.'s current dependence on fossil fuels. Indeed, in the view of many energy-industry insiders, the country's future energy needs can be satisfied easily through the continued use of oil and coal, as well as the use of some non-fossil fuel sources, such as nuclear power. One of renewables' major liabilities, they say, is that they are an unsteady source of energy; the sun does not always shine, nor does the wind always blow. In addition, analysts say the public has warmed to the idea of alternative energy sources in part because oil is a major U.S. fuel source that is expected to become much scarcer over the course of the 21st century.

Renewable Energy Sources

Solar Power

Solar power is one of the best known forms of renewable energy. This form of energy-collection technology uses large panels that collect sunlight, and subsequently convert it into electricity. Though it is not the most efficient form of renewable-energy collection; it usually converts just 15% of available sunlight energy into usable electric power. In remote areas of the world where residents are unable to tap into a national or municipal energy grid, for example, solar power allows people to generate their own electricity (Blackburn, 89).

Wind Power

Growing numbers of countries and U.S. states are incorporating wind power into their energy ...
