Energy Sources Energy is a mysterious force that appears to propel everyone and everything within the known constructs of the universe. All things both require and expend energy in all types of forms and systems. The purpose of this paper is to examine my own personal energy use to determine the extent, sources and destinations of this practice. This essay will include the different forms of energy I consume and expend

Cost and CO2 reduction analysis were performed using local data available from both commercial and professional bodies. A majority of current thermal rating programs require the equipment to be tested in accordance to a standard test under specified testing conditions. This approach provides reliable data because it is possible to replicate such tests within an accepted uncertainty band. There are, however, some rating programs which combine a standard test

Economic Indicators The change in the United States Real Gross Domestic Product (GDP) ratings has shown both ups and downs in the U.S. economy over the last two years. In the most recent quarter, the first quarter of 2011, the U.S. GDP increased over 2%. While the GDP has increased every quarter since mid-2009, the quarterly increase in each of the last four reported periods was weaker than the quarterly increase

9% Yard Trimmings - 12.9% Food scraps - 12.4%; Plastics - 11.7%; Rubber, leather and textiles - 7.3% Metals - 7.6% Wood - 5.5% Glass - 5.3% The following figure shows the number of landfills in the United States between 1998 and 2006 Number of Landfills in the United States 1998-2006 Source: EPA (1997) The work of van der Zee and de Visser entitled: "Assessing the Opportunities of Landfill Mining" states: "Long-term estimates make clear that the amount of solid waste

Notwithstanding these disadvantages, some regions of the European Union, though, are particularly well suited to the installation of wind farms. For example, a 5-megawatt wind farm featuring 10 wind turbines with 500 kW capacity each, has already been constructed in Crete (Greece: Renewable Energy Fact Sheet, 2007, p. 3). Although this wind farm facility is generating electricity, it is also serving as an experimental operation that uses two kinds of

Reasoning for Alternative Fuels All other things being equal, the energy source with the lowest cost will always be pursued after in the cargo transportation world. The supremacy of petroleum-derived from fuels is an outcome of the comparative ease with which they can be stored and competently used for the internal combustion engine vehicle. Other types of fossil fuels (propane, natural gas and methanol) can be used as transportation fuels
