...Law of Conservation of Energy: Statement: The law of conservation of energy states that the total amount of energy in a system remains constant ("is conserved"), although energy within the system can be changed from one form to another or transferred from one object to another. Gravitational Potential Energy: Definition: Gravitational potential energy is energy an object possesses because of its position in a gravitational field. Kinetic Energy: Definition: Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). Elastic Potential Energy: Definition: Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched. After defying of relevant theoretical terms here I am mentioning little comments on the given query. A real life example for conservation of energy is a ball falling from a building. The total mechanical energy is sum of equal to kinetic energy with addition of gravitational potential energy at different periods of time and height. The K.E. and G.P.E. is changing but...

...altogether needs to understand what energy conservation provides because energy conservation may save human lives as well as the entire human population as a whole; the greatness about energy conservation is that it can save households and businesses money. The world today is built upon speed, demand, and the power of energy. Today's human way of life works around consuming energy in many aspects of daily life because we use an enormous amount of transportation, heat, and electricity. Energy conservation is the basic performance of diminishing the amount of energy consumption that takes place in our daily lives. Enormous amounts of human and governmental effort may bring forth a massive reduction of energy costs, as well as cause many humans to become healthier in various ways. In this dissertation, I will provide background information on energy conservation. I will focus on factors and contributors that affect all things on earth non-living and living. In scope, I will also focus on the positive and negative issues that arise with energy consumption, which in turn impacts humans. The reader will review a complete evaluation of current sustainability strategies and solutions for energy conservation. This research will also provide a sustainability plan of its own to deliver to the reader. The sustainability plan will include benefits and challenges of the plan as well as the required government, societal, and global support. In many forms, energy is probably one of the world's...

...Energy Conservation Tips for Energy Efficient Home Robin Pitts Axia College Energy use and conservation is a much publicized topic in the world today. There are many different sources of energy and the focus of this paper will be on home uses. Energy used in the homes comes from a few different sources. Most home uses as of today are from nonrenewable resources. Resources that cannot replenish will be depleted forever, and future generations will need to create alternative sources of energy. Electricity is used to light homes and run appliances. Many electric companies use coal to create electricity. Oil and natural gas are used to heat our homes. This energy is wasted at an alarming rate and will soon be obsolete if we do not address the issues at hand. Nonliving and living factors are affected by the lack of energy, when mining for coal the environment is vastly affected. Valuable land is destroyed and can take years to replenish, if it ever does. Coal is mined two different ways, subsurface and surface mining. There are advantages and disadvantages to both. Strip mining, a form of surface mining is used for the retrieval of 60 % of the coal in the United States; is done if the coal is close to the surface, approximately 100 feet down. Surface mining, a less expensive form than subsurface mining, allows complete removal of coal and is safer for the miners. This is the preferred method, but with this comes an environmental impact. Large trenches...

...Energy Conservation Preston L. Judd SCI/275 Environmental Science Axia College / University Of Phoenix April 10, 2011 Tisha Samosky It can begin simply by turning off a light switch as someone leaves a room or unplugging a device when not in use. From these small acts, the beginning seeds of energy conservation can be sown. Energy conservation has become one of the most hotly debated subjects in the world. Old power plants are struggling to keep up, sometimes causing power shortages or “brown outs”, and new power plants are being built, but most of the new plants still use the same technology as their predecessors. Some have even been ‘repackaged’ to appear cleaner in respect to exhaust, but they still pollute the atmosphere and use a dwindling source of fuel. Still others argue that fields of petroleum at deeper levels are more than sufficient to supply the world with oil1. The only real hope of the world is to either perfect some of the newer, greener power generation techniques such as wind, solar, or geothermal, or invent some new as-of-yet undiscovered method. Until that time, energy conservation is not just a good idea, it is a necessity. 1. The Population Explosion and Power Usage As the world’s population gets closer to the seven trillion mark (estimate as of April 2011 is 6,911,382,8582), the demand for power increases exponentially. The added strain on the generation facilities is causing rolling blackouts, or “brown outs”, in some...

...Final Environmental Science Tiffany Garris April 15, 2012 Marc Romine Energy Conservation Energy conservation is a simple way to solve many problems but the one we are focusing on today is called acid rain. Acid rain is a devastating effect of energy consumption. The only way to reduce it is to use less natural resources, or energy conservation. Energy consumption and air pollution has become a hot topic recently and is so linked to each other that you cannot have one without the other. One of the worst places for acid rain is China. This is due to their massive consumption of energy sources. The nonrenewable resource they mostly use is coal. Their high usage rate is in direct correlation to their high population. The more people they have the more of a need for coal and other nonrenewable resources. The higher usage of nonrenewable energy resources causes higher amounts of acid rain. If we are not careful we will be as bad if not worse than China. Our energy use increased 40% from 1970 to 2000. They are charted to grow another 40% by year 2020. That is at an even faster rate and we are at 2012 so in eight years we will have used 80% more energy than was used in 1969. That is a scary percentage. Acid rain damages everything from steel buildings to water supplies. One of the many things acid rain destroys is plants. That means it destroys the food we eat by destroying the grass and other flora that animals eat, the animals that eat the...

...Energy Conservation Plan Keenan Williams SCI 275 April 15, 2012 Sarah Franklin Energy Conservation Plan Energy is something that is a necessity for the human race to function. People are very ignorant when it comes to conserving energy, which in turn wastes what little non renewable resources remaining and becoming scarcer. A non renewable energy source is something that cannot be reproduced or grown; it comes from sources that can be completely depleted, such as fossil fuels, oils, and natural gases ("U.s. Energy Information Administration", ). When our non renewable sources start becoming harder to obtain, the price to use them goes up. The majority of the energy we use comes from non renewable sources. Energy is wasted daily basis. Leaving lights on during the day, leaving televisions on when no one is watching it, having multiple electronics plugged in to the wall instead of a surge protector, leaving the air conditioner running when no one is home, and doing laundry all throughout the day instead of doing it when the rates of electricity is lower are all ways that energy is wasted. A good way to stop the wasting of energy is to avoid those mentioned activities. These are just small things people can change in order to conserve energy, and if everyone would do it, it could make a big difference. The issue of energy conservation has both living and non living contributing factors. The biggest living contributing factor...

...Energy Conservation SCI 275 Rochelle Troyano May 9, 2010 It would be hard to imagine a life without the use of energy. So many of the products that we use on a daily basis are powered because of electricity, which in turn is generated because of energy. American’s use a mixture of different energy sources to cool and heat our homes, offices and means of transportation. We also use energy sources to illuminate and power these same places. Oil has provided the United States with less than 50% of energy needs and supplies almost 97 percent of the energy used for transportation (Dale and Kluga, 1992). There are two sources of energy that we depend on: renewable and nonrenewable energy. Renewable energy is energy which comes from natural sources which is constantly renewed. Some examples of renewable energy is wind, water, sun, vegetation, and geothermal. Nonrenewable energy comes from natural resources that are unable to be replenished like, fossil fuels i.e. oil, gas, and coal. Also, a large percentage of electric power that is located in the United States primarily comes from nuclear power plants. Current plants that operate possess a significantly large amount of waste disposal problems which in turn mean that there are currently no plans of building any additional nuclear power plants. A mass amount of electricity is generated because of the burning of nonrenewable energy sources. Due to this massive problem, the conservation of energy is a process we need to take more seriously...

...Global energy consumption has increased steadily for much of the twentieth century, particularly since 1950. In 2011, the world consumed 88 million barrels of oil per day, a 7% increase from 2010 (Statistical Review of World Energy, 2014). Most of the energy increases came from non-OECD countries (Statistical Review of World Energy, 2014).In current scenario, for the first time, oil demand in the developing world is expected to be higher than in industrialized world (Global energy usage, 2012).The dynamics of energy markets are increasingly being determined by emerging economies. In recent years, there has been an explosion of growth in energy demand from Asia, which eclipsed North America for the first time in 2003 as the world’s most energy...

...ENERGY POLICY AND CONSERVATION IN NIGERIA: IMPLICATIONS FOR RURAL DEVELOPMENT BY O.ADEGBUYI AND O.O. FASORANTI (PhD) ABSTRACT To impact visible advances in rural communities in Nigeria for achieving meaningful economic goals, the effective policy of energy usage as a vessel for the acquisition and utilization of required technologies to develop and recover the present depreciating national economy associated with poor food production must be focussed strategically. The socio-economic growth of any developing nation is generally a function of the level of maintenance of her energy demand supply balance and sustainable food production. Nigeria may attain the potential status of an industrialised nation by the year 2010 if all available manpower and other natural resources are well utilized before then to effectively harness her potentials of cheaper alternative energy technologies for long term economic and rural developmental goals. This paper presents the nation’s requirement of a well- articulated energy policy and urgent implementation strategies emphasizing on appropriate energy conservation concepts to promote optimal utilization of existing energy resources in her rural areas. It is therefore suggested that the development of available alternative energy resources be encouraged for integrated rural growth, sufficient food production and small scale industrialization thereby alleviating poverty in the rural communities of the...

Conserving energy for these corporations doesn’t only improve their bottom line but also helps to ensure that they are doing their part and are attending to their corporate social responsibility. Within the hospitality industry there are many different ways that a manager can choose to improve the management and conservation of energy. Ensuring that all of the machinery on the property is up to date, well maintained and the most energy efficient model available is a good start to reducing the energy consumed on the property. However, there are other things that can be done as well. For instance, instead of just upgrading the machinery they could replace it entirely with energy conserving technology alternatives. They also have the options of choosing a completely different source of energy, one that...

...solve social problem. After introduce their think tank, a novel topic is show on our eyes. Energy Poverty. Energy Poverty is meaning the family use 10% of their income to pay the utilities, which is a high expense. Beside economic aspect, there are two other aspect we should consider, they are social and environmental. For social aspect, poor people are easier to pay more utilities expense. They maybe turn on the air-conditioning for a long time because they have no window in the house. And they need use the natural gas, and natural gas is a high expense resource for them, so that is also relate to the economic aspect. For the environmental aspect, the poor people are lack of money to buy the energy-saving products to decrease the utilities expense. They will use rice cooker to boil water, they don’t know to use fan and air-conditioning alternately to save energy. So these three aspect are relate to each other, and we should use the social worker to teach people how to use electrical in a right way to reach the purpose of social aspect. And should find some company to invest the fund in economic way to subsidize people. And for the environmental, improve energy efficiency is the most important thing, I think everyone should take a part in this action, to saving the energy and help other people who need helps.
