...How can energy be converted from one form to another? All forms of energy can be converted to another form of. For example: A pendulum is an object is suspended by a string or wire for support. If the object is moved to one side and then released, it will swing back and forth in an arc. At that moment the object reaches the top of its swing, it stops for an instant, and then begins another swing. At that instant of stopping, the object has 100 percent potential energy and no kinetic energy. The object starts back down through the swing, the object is gaining kinetic energy and losing potential energy. At the instant the object is at the bottom of the swing, it has 100 percent kinetic energy and no potential energy. As the object climbs through the other half of the arc, it is gaining potential energy and losing kinetic energy until it again reaches an instantaneous stop at the top, and the process starts over. The kinetic energy of the object at the bottom of the arc is equal to the potential energy it had at the top of the arc. Disregard the friction, the sum of potential energy and kinetic energy remains constant throughout the swing. The fossil fuels are objects that are decomposed over a period of time. The fossil fuels are usually having lots of carbon which is produced into natural gas, coal and petroleum. Fossil fuels also have lower numbers of carbons and create methane. The fossil fuels are an attractive source because they can be burned and create more enough energy...

...Industrial Revolution provided us many technologies that required the burning of fossil fuels to work properly. Today, most of the world’s energy comes from fossil fuels. Whether it is coal, oil, or natural gas, these fossil fuels are burned to help produce electricity for our use. The burning of fossil fuels can have detrimental effects on our environment. Greenhouse gases and other air pollutants are released from the burning of fossil fuels. Additionally, the continued use of fossil fuels will eventually deplete its supplies. In the interest of preserving the environment and maintaining the supply of fossil fuels throughout the world, we must look for alternative methods that will provide us the electricity that we are so dependent on. A Fossil Fuel Alternative Nuclear energy is perhaps one of the most economical and reliable sources of energy in the United States and probably the world. Out of all the forms of energy, it has the least environmental impact – air, land, and water – if handled properly. Nuclear power plants do not emit harmful gases, like nitrogen oxide or any other greenhouse gas. Various forms of wildlife and even endangered species are able to thrive around nuclear power plants because neither the cooling water that is discharged from the plant nor the emissions contain pollutants that are harmful to the environment. Also, nuclear power plants can produce large amounts of energy in a smaller space, so they require less land for sitting and operation. ...

...of alternative energy like solar power aims to decrease the impact humans have on biodiversity due to the issue of enhanced greenhouse effect. Solar power is electricity generated from the levels of natural energy contained within the sun’s rays . Supporters of solar power maintain that this energy source is able to lower greenhouse gases as it is a natural resource that does not require further processing. It can be supplemented entirely or partially which may possibly rule out the use of fossil fuels. Solar power is an infinite energy source which reduces the world’s reliance on fossil fuels. Opponent’s claims that solar power is not constant, it contributes to Global Warming as the production of solar panels used in generating solar power create pollution and is costly. There is a great need for alternative renewable energy such as solar power as the world’s reliance on fossil fuels increases the levels of greenhouse gas emissions. 86% of primary energy used is generated from burning fossil fuels . Due to the large consumption of fossil fuels utilised in providing electricity, fuelling transport, and heating and cooling,large quantities of carbon or hydrocarbons, and carbon dioxide is released when fossil fuels such as petroleum and coal are burned. Approximately 21 billion tons of carbon dioxide is released into the atmosphere yearly which is too much for the atmosphere of Earth to neutralise or utilise naturally. The production of carbon dioxide from burning fossil fuels...

...ASSIGNMENT #1 Energy can be converted from one form to another by one form of energy decreases, other forms increasing, because the total energy has to stay constant and that’s only if you're looking at an isolated object. Potential energy can be converted to Kinetic and kinetic can be converted to potential. (Tillery, Enger, & Ross, 2009, p. 67). Energy can be converted in three basic ways through 3 actions of forces. Gravitational Forces is when gravity accelerates a falling object, its converts its potential energy to kinetic energy. Electric and Magnetic Force Fields can convert charged particles, which electrical fields use forces, possess potential energy of an electric field in a way similar to that of an object in a gravitational field. Frictional Forces can be converted into thermal energy, which is heat, whenever the object slides against another object. An example of an energy being converted from one form to another is a lightbulb. It converts electrical energy to radiant energy. A car can covert chemical energy to mechanical energy. A solar cell converts radiant energy to electrical energy to mechanical energy. A fuel converts to chemical energy to heat energy. What we mean by fossil fuels is that Fossil fuels are energy resources that come from the remains of plants and animals. These remains are millions of years old. Fossil fuels, like coal, oil, and natural gas, provide the energy that powers our lifestyles and our economy. Fossil fuels are a finite, non-renewable...

...discuss how energy can be converted from one form to another, giving specific examples. The ability to do work is how energy can be defined. “Energy is never created or destroyed. Energy can be converted from one form to another but the total energy remains constant” (Tillery, Enger, & Ross, 2009, p.65). There are various forms of energy and terms are used to distinguish one from the other. There are not different kinds of energy even though there are various forms. These five different forms of energy are categorized as mechanical, chemical, radiant, electrical and nuclear. Mechanical energy is a combination of potential and kinetic energy resulting from the force of gravity or the movement or release of a machine component. An example of mechanical energy would be bowling ball (kinetic energy) striking a pin and displacing it (potential energy). Chemical energy is a form of potential energy that is absorbed or released by chemical reactions. Dried wood stores chemical energy and when burned, releases chemical energy that converts to heat and light. Radiant energy is energy that travels through space. An example of radiant energy would be light. The light from the sun makes it possible for living things to live on earth by providing fuel and warmth. Electrical energy is a form of energy from electromagnetic interactions. Electrical energy is the presence and flow of an electric charge. Lightning or a light bulb would be examples of electrical energy. Nuclear energy is regarded...

...Since the beginning of time, mankind has been using energy and converting it to different forms. This conversion of energy from one form to another is known as Thermodynamics. Energy conversion takes place in our every day lives. Many conversions of energy are possible, such as chemical to heat, heat to mechanical, hydraulic to electrical or mechanical. Almost all energy can be converted from one form to another (Kehmani, 2010). Examples of energy conversion can be seen in day to day life. For example, in cars, the chemical energy of fuel is converted into the mechanical energy of the vehicle; in motor electrical energy is converted into mechanical energy, in hydro power plants the hydraulic energy of water is converted into electrical energy, in nuclear power plants the nuclear energy is converted into electrical energy etc. With the Green movement we are seeing increased use of solar energy, such as solar water heaters and solar cookers where solar energy is converted to heat energy (Kehmani, 2010). While mankind has learned to harness energy and convert it to useful forms, Thermodynamics is governed by scientific laws. The first law of Thermodynamics is that energy can’t be created or destroyed (Kehmani, 2010). The second law states that heat energy can only be transferred from a body of higher temperature to a body of lower temperature. The third law refers to the law of absolute zero on the Kelvin temperature scale, stating that entropy of the body at absolute...

...Renewable Energy Page 1 Renewable Energy Nathan Wenzel University of Phoenix Renewable Energy Page 2 “According to a new UN report, the global warming outlook is much worse than originally predicted, which is pretty bad, when they originally predicted it would destroy the planet.” (Jay Leno). Humans are creating a lot of damage to the planet’s environment, and if we don't do anything to prevent the carnage soon, the results could be disastrous. Most people have knowledge about global warming and believe it may be a sincere dilemma in the future. What most people don't know is that global warming is currently happening, and we are already experiencing some of what it is capable of doing. Knowing of the harmful effects of global warming, alternative energy sources need to be pursued. Finding and using alternative energy sources may be the only way to stop the increase of global warming. Global Warming is something that is greatly influenced by the energy crisis. Most of global energy production is produced from fossil fuel such as coal, oil and natural gas. The vast majority of fossil fuels generate energy which is used for many purposes for residential, transportation and industrial...

...Material Fossil Fuels and Alternative Energy Resource Worksheet Using the textbooks, the University Library, or other resources, answer each of the following questions in 150 to 200 words. 1. Select a fossil fuel. How is this fossil fuel used? What are the adverse effects on the environment? The fossil fuel I am selecting is coal. Coal is very important and is very important worldwide for its many uses. There are many different types of coal that are used for many purposes. One of the most important usages of coal is in electricity generation, steel production, cement manufacturing and as a liquid fuel. About 6.6 billion tons of hard coal was used throughout the world last year, and 1 billion tons of brown coal. Coal making needs great amounts of water, which disturbs the environments of the marine and land-based wildlife as well as individuals who use the water. The methods of burning coal for energy gives off greenhouse gases with additional dangerous toxins which include carbon dioxide, mercury compounds and sulfur dioxide. Toxins made from coal mining can also add to acid rain, mainly in the Appalachian area. Also, burning coal creates ash, a solid waste that has alkali and metal oxides. 2. Select a local or regional alternative energy resource. How might this resource be used to supplement or replace fossil fuels? Alternative energy is the term that is used for an energy source that is an alternative for the use of fossil fuels. An alternative energy source...

...2012 Oil vs. Ethanol In today’s society most people get from point A to point B with a car. That car that society drives, however, doesn’t run all by itself. All cars need some form of energy to operate. The world’s primary use of energy for cars is oil. As we know, our global amount of fossil fuels, especially oil, gets a little more scarce everyday. Researchers have developed different kinds of alternative energy to help slow down the use of fossil fuels. Ethanol has turned into a top source of an alternative for oil. So why not use those alternative forms of energy like ethanol for every car? Through studies and research, scientists continue to evaluate the downside of fossil fuels, possible harm of alternative energy, the benefits of fossil fuels, and successes of alternative energy. Earth’s primary energy supplier has always been fossil fuels. Fossil fuels are made from animals and plants that lived many millions of years ago. Those plants and animals became buried underneath the surface of the Earth where they transformed into what we use today for oil. We have depended on those fuels to meet our most basic energy needs, to our most complex. Society runs into the problem that fossil fuels are a non-renewable resource. Once they have been depleted, the fossil fuels are gone forever. The problem comes up when miners, oil companies, and oil consumers destroy different ecosystems. The mining and oil production that occurs has caused a major dent our environment...

...First discuss how energy can be converted from one form to another, giving specific examples. The seven major forms of energy are: sound, chemical, radiant (light), electrical, atomic (nuclear), mechanical, thermal (heat). Remembered as “SCREAM Today” The two states of energy are potential and kinetic. (Clarkson, edu.2008). Energy can be converted to useful forms by various means. Energy and its conversion between forms can be expressed quantitatively. When converting energy, a significant fraction of that energy can be lost from the system (in the form of heat, sound, vibration, etc.) For example: in a power plant burning coal will produce heat energy, heat energy transfers to the water causing water to turn into steam, steam move the turbine due to pressure, energy is now transfer from heat to mechanical energy, then mechanical energy is converted to electrical by the generators, here we have a good example of energy converted to another form. Another example: leave a stone from a certain height and it will fall straight down. all the potential energy has been converted into kinetic energy. (YahooAnswers.com, 2012). Define what we mean by fossil fuels and explain why there an attractive source of energy. Fossil fuel consists of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content. They are attractive because they are or were, readily available, can be easily transported and can be refined to several...

...concerns with wider environmental needs, thereby allowing the benefits of renewable energy to be realized through careful design and consultation. Additionally, it also provides a profile of a major wind power company in Canada. Problem Electricity generation produces more pollution than virtually any other single industry in Canada. Pollution, air quality, acid rain, nuclear waste and global warming are the unwanted side effects of traditional power production that endanger the environment. Every day, many fossil fuel consuming contraptions spew out gases that pollute the environment. However, when the fuel supplies for these devices run out, they will grind to a halt. To prevent this, Canada needs to find an alternative to unstable and polluting energy sources. Purpose The purpose of this report is to examine wind energy as alternative energy source and effectiveness at reducing emissions by replacing power generated from fossil fuels. Scope The report will examine wind power as an alternative energy source and nonmarket issues. Wind power usage in Canada has been growing at a significant rate in the past few years and has generated considerable interest in industry, government and the public. Introduction As a renewable energy source, wind power is gaining popularity as an alternative to fossil fuel, nuclear and hydro power generation. In Canada, provinces are required to achieve 15% of their energy consumption from wind by 2012 as provinces...

...Assignment #1 Energy Student: Instructor: Course: Introduction to Physical Science Date: First discuss how energy can be converted from one form to another, giving specific examples. Energy can’t be created or destroyed but it can be converted from one form to another. It can also be transferred from one object to another (Phun Physics). An example would be a car accelerating. When a car accelerates the gasoline has energy stored in it that is released as heat by burning it inside the engine. At least 10% of the heat energy is converted into the cars energy of motion. The rest stays in the form of heat which is released by the cars exhaust (Phun Physics). Another example could be when two cars collide in a traffic accident. When the two cars collide they release an energy that can be transferred from one to the other (Phun Physics). Define what we mean by fossil fuels and explain why they are an attractive source of energy. Fossil fuels are natural resources that can be converted into energy by a simple combustion process. The main types of fossil fuels used are coal, natural gas, and petroleum (Oracle). Some of the advantages of fossil fuels are that they are easily distributed, relatively inexpensive, are readily available, and can be converted through a simple combustion process (Oracle). Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs (Word Coal Association). ...

...Salako Tejumade Dr. Matthew Lerberg ENGL 1302-019 20 October 2014 Fossil fuel: Are they worth it? A very reasonable percentage of the UTA faction is definitely aware of the fast rising problems fossil fuels are costing our global environments and the controversy with intent of finding alternative energy sources. Nevertheless the public has appreciated most of this interference with no doubt but some others have resulted in some real dissension. One of the most common controversies that can be put before us is reason for the rise in sea level that deviates from anatomic evolution to the management of water resources to the highly debated issue of climate change. One can think that it is developing as a result of natural instability of the climate system or that it is human-induced, mainly from the burning of fossil fuels. Moreover, our global environment has many problems, If the extent of carbon radiation increment is one, low level of intellective involvement accompanying some of the extreme concurrent objections are definitely in addition. Furthermore, there is several captivating and scrutinized investigation on selective concurrent complications just as global warming, and yet some of the foundational issues have remained unresolved and unaddressed. In this paper I will review three main positions areas of neglected environmental analyses that demand immediate attention. First, is the widespread problem of not possessing anything like a general normative infrastructure...
