May 10‚ 2012 Reality Check to America’s Energy Policy The invention of electricity‚ to many‚ can be considered one of the greatest inventions by humanity‚ behind writing and the wheel. From its first discovery in the 1600s till present day‚ electricity has fascinated the minds of scientist everywhere. Over time society has been established with a very high dependency on this commodity. Imagine our world today without electricity or any of the inventions derived from it. Modern societies would

Using natural energy resources doesn’t necessarily mean you will conserve any energy‚ yet we do advise every household to research the possibility of implementing natural energy resources to influence their home power supply. This will conserve the fossil fuels we are currently consuming at an alarming rate. Many little things can be done in an attempt to conserve energy in the home. It is knowing how to do these little energy conservation processes that many people do not know about‚ understand

assess personal energy use and speak about the forms of energy that I currently rely on and the sources they originate from. It also talks about renewable energy sources that would be most and least appropriate to use in a certain location. Then it refers to the advantages and disadvantages of the energy source that I currently use‚ also about renewable ones that have been identified. The last part of the paper addresses energy conservation and its impacts on the environment. Energy is embodied in

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Energy Production Controversy Imagine the U.S. without cars‚ motorcycles‚ planes‚ or boats. The daily lives of U.S. citizens would be completely different. The common denominator for all those modes of transportation is that they run on gas‚ which is made from fossil fuels. Fossil fuels such as oil‚ coal‚ and natural gas are nonrenewable resources. They will run out one day and that’s what the U.S. relies on for gas and electricity. Renewable energy such as solar‚ wind‚ and hydropower are infinite

Lucky Koritela #23 The Rock Cycle The rock cycle begins when Earth’s plates shift around leaving gaps in between them making a volcano. The magma under Earth’s crust come through the gap and spill out of the volcano. Then the magma (lava) cools down and hardens into igneous rock. As time passes the igneous rock weathers (using substances such as water) away into little chips. After getting smaller‚ erosion (using elements such as wind) transports the little rocks to different places. The deposition
