...Energy Tammy Malugen Professor Trena Woolridge Environmental Science and Sustainability SCI201-1501B-15 When you were a child you always heard the phrase “turn off the lights!” or “close the door you weren’t raised in a barn!” The Law of Conservation of Energy is the corporeal code that the entire extent of energy in a method is perpetual, even though energy is different from some form to a different or moved from one purpose to another; this can too be called the first law of thermodynamics. What this means is that since you cannot destroy energy but you can transform it into another form of energy. By using energy efficient appliances doesn’t mean you don’t use energy it just means that that energy is being converted into a different form of energy within your home. There are many forms of energy: Fossil Fuels, Nuclear Energy, Solar Energy, Wind Power, Water (hydro) Power, and Bioconversion (biofuel). Fossil Fuels: In 2007, “The U.S Energy Information Administration (EIA)” has determined that 86.4% of the main energy depletion that can be traced back to non-renewable sources. Pros: Well Developed: the reason fossil fuels is used is because it is the one that is well developed and has been used all around the world Cheap and Reliable: this is cheapest source of energy and the most reliable to use for the base-load. Cons: Contribute to Global Warming: this source of energy is not “green” and contains high amount of carbon Non-Renewable: Fossil fuels are a...

...use of different energy which include fossil fuel: oil, natural gas, coal, nuclear energy, solar energy, wind power, water (hydro) power, and bioconversion (biofuel) these laws could allow the possibility of tax incentives. The use of different types of natural energy can pave the way for a greener earth. Although, some may argue that there are pros and cons of such energy. In this paper we will be discussing these pros and cons as well as two provisions of the Energy Policy Act, 2005, including its tax incentives. 1.) The law of conservation of energy states that energy may neither be created nor destroyed (The law of conservation of energy, n.d). 2.) The pros and cons of fossil fuel: oil, natural gas, and coal. The pros are its high efficient, cheaper than non-conventional forms of energy because it is easy to extract and process them and it the potential to power the entire globe. The cons are Fossil fuels are believed to be the largest emitters of greenhouse gases, responsible for global warming and climate change. It is also believed that coal mining creates earthquakes. The biggest con of all is that they are non-renewable. Nuclear Energy creates little amount of CO2 and it can generate a great amount of electrical energy in one single plant. But these plants produce radioactive waste; the energy source is uranium which there is limited supply. Also nuclear power plants could entice terrorist to attack. Solar energy is renewable source of energy, its clean, provides...

...Clement Yedjou 12/08/214 The amount of energy in an isolated system is conserved eventually, energy can be changed from its original form to a different form are from one object to another. This energy law applies use which is taken energy and changing into a different form, one example is Solar Energy; energy from the sun can be changed in to useable energy for homes, schools, hospitals etc. The energy conservation law also applies to considering that some energy is wasted during the change, it’s impossible to change energy and not waste some of it. Cons and Pros of fossil fuel and oil, natural gas, and coal are pros consist of higher efficiency, it’s less expensive than none conventional reason being it’s easy to change and process them also has the ability to power the globe, the cons of fossil fuels are they have the biggest emitters of greenhouse gases which is mainly the reason for climate change and global warming. Coal mining creates quakes that’s also believed, they are none renewable so that makes it the biggest con. Nuclear Energy creates small amounts of oxygen and it generates huge amounts of electrical energy. Waste is radioactive when produced in these plants. Uranium is the energy source which has a limited supply; nuclear power plants could encourage terrorist attacks. This source of energy is renewable. Solar energy it provides energy to homes with solar panels and there’s no up keep required most of the energy is produced in the light because the panels...

...Paper Alternative Energy The continued use of the planet’s fossil fuels will eventually come to an end and will require an ultimatum to be made. Other sources of energy must be found to sustain this dependency that society has created, so it can continue to fuel our everyday needs. Although scarcity is a leading factor in the search for newer resources, the damaged caused by fossil fuels need to be reversed, including pollution and global warming. Every day there are more and more advancements, innovations, or even inventions of new alternative resources that need to be taken advantage of to maintain a stable and reliable source of energy. Alternative energy sources such as solar, wind, and hydrogen energy are more durable and efficient to be used as a substitute for current natural resource uses. Foremost, fossil fuels have been a primary source for energy for years, and had some major consequences alongside them. Pollution is no new name to the harm our environment receives and it comes from the burning of fuel. As well as pollution being created, global warming, which is a huge debate in today’s society, is also caused by burning fossil fuels (Rinkesh “What are fossil fuels”). Not only does it damage our environment, but it causes health problems for its wildlife and our own lives. These hazardous effects will have a long term duration and require a cleaner solution and that is natural resources (Rinkesh “What are fossil fuels”). These alternative energy sources would...

...08 IP3 August 9, 2014 . The first law of thermodynamics would consist of energy not being able to be formed or demolished. Energy is all around and it is made up of everything no matter if it’s the smallest particle or biggest. Being that energy can reorganize itself, it will always change from one form to another. The second law of thermodynamics would consist of the entropy; if it is not in a thermal balance then it will almost always increase. You can say that in the second law would state that if a room is not cleaned it will perpetually become more messy and unsystematic with time. The third law of thermodynamics would be that when a entropy reaches a constant value as it approaches zero. Fossil Fuel pros and cons, the pros of using fossil fuel is that we are able to develop new technology to harness energy from this natural source. Fossil fuel is cheap and there are no other things needed to gather energy from this fuel, it is considered being a reliable source of energy. Think about load-based needs, fossil fuel is more preferred then other sources of energy that are consider being unreliable. The cons of using fossil fuel are that it contributes to the worsening of global warming. Fossil fuel is not an environment-friendly source of energy even dough it is consider a natural source. It is the main contributors in global warming due to it releasing high amounts of carbon. Nuclear energy unlike fossil fuel does not release smoke in the atmosphere. It is ran off electricity...

...Sources of Energy The law of conservation of energy states that the total amount of energy stored in a system will be constant throughout time. Since energy remains constant in a system, it cannot be created or destroyed, but it can be converted into other forms of energy (Law of Conservation, n.d.). Other forms of energy use include fossil fuels, nuclear energy, solar energy, wind power, water (hydro) power, and bio-conversion (biofuel). There are both pros and cons in using these various forms of energy. Fossil fuels are a common source of energy used that are naturally occurring substances found on the surface of the earth. It is a non-renewable source of energy. One major advantage of fossil fuels is their availability. They can easily be found on the surface of the earth. However, depletion of this non-renewable source of energy is increasing because of the demands. Therefore, in the future there will a high demand and a low supply of fossil fuels (Energy.gov, n.d.). Nuclear energy is a controversial non-renewable source of energy. According to Maehlum, about twenty percent of the entire electricity generation is produced using nuclear energy. Generating electricity at a nuclear power plant is relatively low in costs as well as low in pollution. However, the nuclear waste is potentially harmful to both humans and the environment (Maehlum, 2013). Solar energy is a renewable energy source. As long as there is sunshine, solar energy will be available. Solar...

...The renewable energy debate has pros and cons coming from both sides. My viewpoint on the issue is that renewable energy can benefit the environment, if we can keep the cost of the sources to a minimum. There are many sources for renewable energy from solar power and wind power to biofuel. Although the sun and the air are free, it does take sufficient amounts of money to build the devices that can harvest these natural things and turn them into energy. In opposing renewable energy people are afraid that we will use up massive amounts of land to put up solar and wind power plants. If these people would think outside of the box, they would be able to see that there is so much land out there that we are not currently using and probably never will, so that land would be getting put to good use and it would be saving the environment. One of the biggest reasons that people resist change is due to fear (Ruggiero, 2012). There are many of situations where renewable energy will benefit our country. We have so much pollution from the current energy sources that we use and we are also to the point where oil is a day by day fuel, it is hard to tell when our supply will run out. When it comes to promoting renewable energy, some people take their belief that this is best for our environment a little too far. They begin protesting the forms of energy that we currently use. According to Ruggiero (2012), Too many people do not make up their own minds, but have their minds made up for them...

...May 25th, 2010 English 1010 Prof. Mrs. Betancourt Energy emergency! Starting from humanity history, humans have been trying to create and establish new things to have better conditions at life. We know from physics lessons that if we want to do a new invention, we need energy in progress. The variety of energy sources actually enables people to obtain their needs in terms of this issue. Due to this fact, the usage of those energy sources has beneficial effects when they are used in the right progress. Sustainable and renewable energy sources such as solar, wind; hydro, oceanic and geothermal energies provide the needed energy for people efficiently and are the best options to improve our planet future. Firstly, economic benefits are very important for societies nowadays in the world. As a result of this, societies are trying to find cheaper way to produce energy. Here we can suggest geothermal energy. The source of geothermal energy is hot underground water. This kind of water can be found by sounding and this technique is not expensive. After making canals that water flow inside it is enough to finalize the progress. Energy types which are produced by sun are example of this situation. Besides from the normal risks, geothermal energy can also provide a cleaner source of energy. According to Energy Consumers Edge (ECE) “geothermal energy use does entail some environmental impact, but it is safe to say that the environmental benefits far outweigh the costs’’. Most geothermal...

...My Thoughts on Renewable Energy My Thoughts on Renewable Energy Renewable energy is a much debated topic in our society today. There are those who are supportive of the idea and then there are those who are strongly opposed to renewable energy efforts. Individuals who encourage renewable energy typically make a good argument about our fossil fuel shortage, harmful gases, and pollution caused by fossil fuels. They declare that renewable energy is “clean energy”. However, those opposed to renewable energy also make a convincing argument on their behalf. They claim that renewable energy is a great expense we cannot afford, it requires a large amount of land, and causes environmental damage. I have always been “pro” renewable energy. I am 23 years old and have grown up in a society that endorses and promotes renewable energy. There are commercials on television about renewable energy. There are ads on the internet about renewable energy. I see many charities and financial efforts being made to help with renewable energy. America’s motto nowadays is “go green”. I suppose because I have always seen renewable energy put in such a positive light I have always thought it was the best energy solution for us. Reading the opposing material this week has actually been the first time I have really heard about renewable energy being frowned upon. I believe that the habit that hinders my thinking in this situation is conformity. I am guilty of conforming to what society thinks is the best...

...1. Solar Energy/ Solar Architecture (What is it? Is it a problem? How does it aid or cause problems both for our environment and our personal health? Research uses, types, etc. What are the issues, discuss the pros and cons of the issues and suggest environmentally safe choices. Solar energy can be used for day lighting, cooking, heating water or other fluids, distillation, disinfection, making saline water potable and high temperature process heating. Solar energy in building is used by orientating the house relative to the sun, making it more compact, including patterns of selective shading and choosing building materials with certain thermal mass (heat capacity of a material). Every house should also be tailored to a certain climate it’s going to be located in. In agriculture solar energy is used to increase the productivity of plants. There are such methods of ensuring growth as timed planting cycles, row orientation for the plants to get as much sun as possible etc. The commonly known greenhouse in fact also uses sun energy that is converted into heat to provide for the year-round growth of certain plants. Passive Solar Energy doesn't use mechanical means to collect, store, or distribute the solar energy. For example, a thermosyphon (solar water heater) will use natural convection to circulate the water through the system. Active Solar Energy uses mechanical devices to collect, store, and/or distribute the solar energy. For example, active solar water...

...Jordan Bailey Energy Resource, Oil Looking back in time the earliest oil well drilling was done in 4th century China, maybe even earlier. The Chinese burned the oil to evaporate brine and produce salt. They also probably used the oil for lamps and possibly to an extent to heat themselves as well as their homes. By the 10th century, extensive pipelines connected oil wells with the salt springs. In the western world, the petroleum industry started near Titusville, Pennsylvania, with Edwin Drake’s discovery of oil in 1859. The new oil industry, the fuel oil and home heating oil industry we know today, grew slowly in the 1800’s and did not become a real national concern until the early part of the 20th century. The internal combustion engine created a whole new scenario for the oil industry which provided and still provides a demand for refined fuel oil that still exists today. Early finds of oil like those in Pennsylvania quickly ran dry leading to “oil booms” in Texas, Oklahoma, and California. Other countries had much larger oil reserves and stated to develop them at an industrial level. As late as 1955 coal was still the world’s most used fuel. Oil then began to take over the scene and became the predominant fuel to heat homes. Following the 1973 energy crisis and the 1979 energy crisis there became the concern that oil is a limited resource and will eventually run out, at least as an economically viable energy source. In 2004 there was a report done by USA Today news...

...Stafford December 13, 2012 Energy of The Future In today’s day and age roughly sixty percent of citizen of the United States get their electricity from fossil fuels. This is not too bad but this is still a problem due to the fact that it causes a lot of pollution from the burning of fossil fuels. Out of one hundred percent, wind energy is responsible for giving four percent of the American population electricity. The atmosphere is not going to get better on its own so we must take action from moving from burning fossil fuels to renewable energy like wind energy. Although it would be a very slow process, the atmosphere and the wallets of every American family would benefit from the change. Wind energy, unlike fossil fuels, is available through wind turbines. These tall towers with huge blades move in a circular motion where they capture wind in between the blades. The blades in a turbine are connected to a shaft inside and this only has 18 rpm (rotation per minute), which is nowhere near enough to create electricity for homes. So because of this the shaft is connected to a series of gears that roughly has 1800 rotations per minute. With the gears moving 1800 times a minute this creates electricity, which is transmitted to a generator. From there, the turbine is connected to a transformer, which increases the voltage of the electricity in order for it to flow through the transmission lines. Once the electricity reaches the transmission lines the energy flows to the grids of electric...

...order to do that, the management of the company would raise the required financing from the later stage growth equity investors or from the Department of energy. The manufacturing of the wafers would be done by the company in the United States and then it would export those wafers to the Asian cell manufactures. On the other hand, the second option for 1366 Technologies was to go for a licensing agreement or a joint venture. Through this partnership approach, the company would rapidly gain scaling and it would also allow the Asian partners to lower their costs of production. The management of the company has always supported the accelerated growth however; the company might face significant risks if the intellectual property is exposed to the wrong partners. If the management of the company considers this option, it would lose its technology however, looking at the pace of innovation in the industry and the changes in the solar industry caused by the active involvement of the governments, Sachs and van Mierlo knew that they could not win the race by being cautious. First of all, if we interpret the Levelized cost of energy (LCOE) comparison and its sensitivity against the fuel prices as provided in the exhibit 5b, then it could be seen that the PV solar is expensive as compared to many other forms of the renewable energy in most parts of the world. Therefore, it is guaranteed that the management of 1336 Technologies needs to find a way to build its competitive edge in the...

...location that we chose is Hilo, Hawaii which has around 44,000 people and rising. The area is sunny and humid throughout the year. We want to build a small community of about 20 units using recycled shipping containers. There is an abundant amount of natural resources to be utilized such as the wind for wind turbines, sun for solar power, free flowing streams for irrigation, and geothermal energy from the Puna Volcano. The initial cost may be high because of how remote the islands are therefore making getting supplies difficult due to shipping. The purpose of a green community is to reduce energy consumption, improve health and reduce impact on the environment. Well-designed green buildings will save money by off-setting the rise of electricity and increase comfort for people by improving air quality. The cost of using electricity will continue to rise which will increase the demand for renewable energy. Since Hawaii is made of islands, we thought it would great to use green buildings to save the resources left in Hawaii without destroying anymore trees or using fossil fuels for energy that’s having an effect on global warming. Also, there would be a limited amount of land left as the population continues to grow. Another purpose of a green building in Hilo is save money on people’s pocket since the cost of living is pretty high through lowering monthly bills by an estimated $92. We would be buying 18.2 acres of land for $500,000. The average cost of a use shipping container...
