Geothermal energy which is heat energy can be found in almost everywhere on Earth. It is a renewable energy derived from heat deep in the Earth’s crust. The word “geothermal” comes from Greek words meaning “Earth” (geo) and heat (thermal), it means using the nature heat produced inside the Earth. (Davor Habjanec,2008)The use of geothermal energy occurred more than 10,000 years ago with the settlement of Paleo-Indians in hot springs. The technology of geothermal energy improved each year. In 1904, the first geothermal power plant was built in Larderello, Italy. Although geothermal energy's installation is expensive, it is an efficient and reliable energy resource which does not cause significant pollution, it is renewable, and we can predict the output power with remarkable accuracy.
Commercial geothermal power projects which is the geothermal power plant, are expensive. The exploration and drilling of new reservoirs come with a steep price tag. Total costs usually end …show more content…
Geothermal reservoirs come from natural resources and are naturally replenished. In other words, geothermal energy is a resource that can sustain its own consumption rate, unlike conventional energy sources such as coal and oil; they are not sustainable. According to scientists, the energy in our geothermal reservoirs will literally last billions of years. The geothermal energy source is the unlimited amount of heat generated by the Earth’s core. Earth’s heat is being constantly replenished. The Earth’s heat mostly originates from the radioactive decay of elements such as uranium. This make the geothermal energy more useful than oil and coal energy. Both coal and oil are nonrenewable and contain the most CO2, which is considered the largest contributor of global warming. Even though there are some limitations for geothermal energy, there are a lot more advantages for geothermal energy than its disadvantages which is high

Alternative Energy

...Daniel Munoz English135 Prof Layton 3/24/13 Essay#1-Explanatory Alternative Energy What is Alternative Energy? It’s an energy generated, in ways that do not deplete natural resources or harm the environment. There are about four types of natural alternative energy. Each energy has a different element used to create energy. The types of energy are wind power, solar power, geothermal power, hydroelectric power, and nuclear energy. In the next paragraphs, I’m going to explain the reasons why the world needs alternative energy and how the energy is harnessed. First type of alternative energy is wind power. Using large blades can capture the winds power. The wind causes the blade to rotate turning into electrical current. Electric generators harness all the energy and distribute it to small towns or larger scale towns. There are some advantages for using wind power. First, it causes no pollution. Meaning there are no harmful by-products. Keeping the world safe. Second, wind power is a renewable source; we will never run out of wind. Third, wind turbines can be placed practically anywhere. All you need is a good source of wind. As with any energy source, there are always some concerns. One concern is that wind is never constant. Some days there is significant amount of wind. Then the next day no wind at all. Another concern is that residents that live next to turbine blades think they are ugly. Second type of alternative energy is solar power. This is created by capturing...

...Renewable Energy hotmail2008 Table of Contents Executive Summary 2 Introduction 3 Wind Energy Data 5 Analysis 6 Conclusion 8 Bibliography 9 Executive Summary The majority of our nation’s energy is highly dependent on finite fossil energy sources, like coal and oil. Using fossil fuels to create electricity creates emissions that are both harmful to the environment and our health. Renewable energy sources provide a clean and viable long term alternative to fossil fuels. Renewable energy is energy generated by natural resources in the form of solar, wind, geothermal, hydroelectric, and tidal waves. Among the diversity of renewable energy, wind energy is the fastest growing power technology in the world. According to the U.S. government Energy Information Administration, the production of wind energy will be at least 20% by the year 2030. This report will prove the validity of this statement by using hypothesis analysis. Hypothesis analysis will reject the null hypothesis that wind energy production will be less then 20% in favor of the alternate hypothesis that states wind energy production will be at least 20% or greater. Introduction The majority of our nation’s energy is produced from the burning of fossil fuels, like coal, oil, and natural gas. Life as we know it and our economy revolves around these finite resources. Unfortunately, with our great demand for energy, especially gasoline, world production of oil has already reached its maximum...

Geophysics

...Joseph N. Frederick III PSC 1121C Spring 2011 Geophysics Geophysics can be broken down into several groups that deal with physical science and the earth. It is a field and profession that combines geology, mathematics, and physics all in an effort for people across the world to understand the ways of the world and exactly what it takes for certain seemingly unnatural events to happen. Geophysics covers a range of ideas from gravity, heat flow, seismic waves that cause vibrations through the Earth’s layers, radioactivity both geothermal and geochronological, electricity, electromagnetic waves and magnetism, fluid dynamics, and even condensed matter physics. So as we see, geophysics is indeed a very broad subject, yet when looked at under specific lights, we see that geophysics is no more than a name, a container, for all matters Earthly related. Most of these topics will most definitely be covered in this essay and if not talked about in depth, definitely mentioned seeing as how all of these ideas are valuable to everyone worldwide in getting to know and understand the way our home planet works in relation to ourselves and the space we occupy in the universe. (Beroza, Nelson, and Ilich, "The Department of Geophysics"). History The first traces of anything geophysically related first appear in regions inside of China during the Qin dynasty somewhere between two hundred twenty-one and two hundred six B.C. when Chinese fortunetellers used lodestones to create their fortune...

Energy Independence

...Essay 1 Energy Independence 9/28/2011 Persuasive Writing Charles Mountin Thesis Statement  America needs to achieve energy independence and reduce its dependence on foreign oil.  Abstract The United States need to lower its dependence on foreign oil. The U.S. dependence on foreign oil has created a huge trade deficit that puts billions of U.S. dollars into the hands of countries that are not U.S. allies. This dependence also could lead to an economic downturn if there is another spike in oil prices. The U.S. needs to find alternatives to foreign oil that are environmentally sound and U.S. made to achieve energy independence. America needs to find new energy sources and better energy conservation to meet its future energy needs. As of now America is far too dependent on foreign oil for its main energy source. Many experts say that the world is at peak output for oil right now and will be decreasing into the future. Right now the world has about 6.7 billion people, but by 2050 the estimate for world population is more than 9 billion people. That means we need a lot more oil than we now produce and our production capacity is already almost at its peak. If are still powering our cars, factories, and homes with oil when oil starts to run out we will be in a lot of trouble. In 2008 when oil supplies were near capacity the price of gas shot up to over $4.00 a gallon and I could barely keep up with my bills because of the extra money spent on gas. The price spike also...

Natural Resources

...Introduction The energy consumption of western cities' households stands at about one-third. Energy is a very good example of a natural resource. In as much as it is surprising, efforts have been made since the 21st century to try and conserve these natural resources (Montana Conservation Council, 1956, p. 12). The essay seeks to discuss how some of the activities carried out have been used to promote resource efficiency and sustainable management of natural resources. The essay seeks to detail information on some of the case studies depicting the impacts of these activities. Promotion of Energy Efficient Bulbs The energy efficient bulbs are energy economical due to its insignificant consumption of electricity. According to the results obtained by conducting a series of tests, the bulb converts about 80 percent of the electrical power to light energy. The other 20 percent is therefore converted to other forms of energy such as heat. When compared to traditional bulbs, the results were opposite to having 80 percent of the energy wasted by being converted to other forms while 20 percent being converted to light energy. Adoption of Renewable Energy One of the ways adoption of renewable energy has contributed towards the conservation of natural resources is through enhancing energy security. When one looks at some of the renewable sources of energy such as solar, wind and geothermal, all these sources provide viable energy sources that do not run out unlike the fixed energy sources...

Common Ground

...English 101 17 July 2012 Common Ground Essay The first commercial coal mine in America was started in the 1748. ("History of US Coal Use.") The first commercial oil well in the United States was drilled in 1859. (Yergin, 7) These two fossil fuels were the power behind the American Industrial Revolution, and wealth behind Edward Berwind and John Rockefeller(Brinkley, 435), respectively, that continue to provide power and fuel in present day society. Natural gas is another fossil fuel that helps to provide for the needs of today. Oil, coal, and gas companies tout new technologies that make their products cleaner and safer for the environment. Opponents of fossil fuels say there is no way to burn them cleanly. Proponents for fossil fuels believe there are plenty of reserves to keep America running on fossil fuels for years to come. Advocates for newer technologies, “green” technologies, such as solar power, geothermal energy, and biofuels claim that the time to move on from these fossil fuels has arrived. The new energy sources claim to be renewable so as to never run out. (E.g., the sun would have to supernova for solar power to run out.) They believe the point of “Peak Oil”- the point at which worldwide oil production begins to decline, has already passed and the country will need their new technologies to keep pace during the changing of the energy guard. There are many lenses through which to look at the use of all these energy sources. The end of the debate as to which...

Alternative Energy

...Essay on alternative energy Since hundreds of years oil and gas has been pumped out of the Earth. They are the lifeblood of the modern world and the combustion engine, their heart. The amount being pumped every year is increasing and so is the demand. But how long can this go on for? Oil and gas, the energy lifelines of the world today, will come to an end someday. That someday is not so far, and the world must look for new sources of alternative energy. When we speak of alternative energy, we don’t refer to any which consume fossil fuels or nuclear energy which have undesirable consequences. Alternative energies are energy sources that are renewable and free. As our climate is already suffering from dire consequences of industrialization, we must look for energy sources that release the least amount (if not none) of carbon emissions. These may include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources. One of the best choices from environmental perspective could be the use of Solar power which has already been implemented in many countries on test basis. A 1.5 killowatt Pv system will keep more than 110,000 pounds of carbon dioxide, the chief greenhouse gas out of the atmosphere over the next 25years. With solar, there’s no acid rain, no urban smog or pollution of any kind. The energy relies on the nuclear fusion power from the core of the Sun. It can be collected and converted in different ways. Even though solar power is still not sufficient...

Examples of PTPs E. Benefits of PTP’s IV. Conclusion   Publicly Traded Partnerships (PTPs) and the passive loss limitations According to the IRS Publication 925, there are two sets of rules that may limit the amount of deductive loss from a trade, business, rental, or other income producing activity. These rules apply to individuals, estates, trusts, personal service corporations and closely help corporations. When it comes to PTP the rules must be applied separate to income or loss from a passive activity. In this essay I will tell what a PTP is and I will also give examples of some PTP’s. I will also tell what benefits these PTP’s claims will result from their investments. A publicly traded partnership (PTP) is a partnership between limited partners who provide the capital for the company and the general partners who manage the company. Limited partnership shares in the company are publicly sold by the partnership, offering equal equity or dividends of a public traded company. The publicly traded partnership must withhold tax on any actual distributions of money or property to foreign partners Real estate, energy (including alternative energy fuels), transportation and commodities are some of the PTP’s that the IRS restricts to limited partners...

Interesting Facts About New Mexico

...Monument(as mentioned earlier in the essay,)Bandelier National Monument,and last,but not least,the Chaco Culture National Historical Park. New Mexico’s richest natural resource turns out to be minerals,and,interestingly enough, New Mexico is one of the U.S. leaders in output of uranium and potassium salts,as well as petroleum,natural gas,copper,gold,silver,zinc,lead,and molybdenum. And although I don’t know what half of these things are,it is still pretty interesting. Speaking of Uranium,did you know,that since 1945 New Mexico has been a leader in energy research and development with very extensive experiments conducted at Los Almos Scientific Laboratory which was mainly a research facility in the in the nuclear,solar,and geothermal areas.So some very interesting experiments have happened in New Mexico,like the atomic bomb that was mentioned in the third paragraph. As you know,New Mexico wasn’t always part of The United States of America. In fact most of New Mexico was acquired in 1848 as a result of the Mexican War. The rest of the land would be purchased in a document that would be called the Gadsden Purchase. Later,The Union would capture New Mexico from the Confederates in the Civil War. Just a little interesting fact. All in all,New Mexico is a very beutiful,interesting,and cultural state. I would recommend visiting it at some point in your life so uou can experience its beuty for yourself. But that is just my opinion. Thank you for reading my essay. ...

Ecological Footprint

...Ecological Footprint Since the industrial revolution, human’s demand for natural resources is greater than ever. Consumption and waste are extremely high in some countries and this is negatively impacting on our natural environment. If human’s develop the world by destroying the environment, that will not be lasting and sustainable development. We need to find the way to deal with the human development and also preserve the natural resources. The definition of the ‘ecological footprint’ is a way of measuring our impact on the natural environment as a result of our resource use(WWF, n.d). The purpose of this essay is to find out the ecological footprint in different countries and how resources being used and give to my personal suggestions. This essay, will compare the ecological footprint between two countries, Japan which is developed country and China --- developing country. China consumes 15% of the global biocapacity, and is in the second place in the world but also has the largest population. In 2003, China’s ecological footprint was 1.6(China Ecological Footprint Report, 2012), under the global per capita average of ecological footprint. Carbon footprint occupies half of the whole ecological footprint. From the same year’s figure of The Ecological Footprint Countries (China Ecological Footprint Report, 2012), Japan 4.4 per capita is in the first of Asian countries. Japanese mountain accounted for 73% of total land area, in addition to agricultural land, one percent...

Global Warming

...the atmosphere will prevent most of the outgoing infrared radiation at the atmosphere from escaping into outer space. The main source of carbon dioxide emission is the burning of fossil fuels to generate energy in order to meet our daily requirements. Although the dependable energy supply by fossil fuel is essential in our every day life, because of its adverse effect is why the government should implement policies to encourage the use of renewable energy resources to conserve the environment. Fossil fuels like coal, petroleum, uranium, natural gases are non-renewable energy sources, which mean these resources cannot be re-made or regenerated. In contrast to that, renewable energy resources like hydroelectric energy, solar energy, wind energy, and geothermal energy do not deplete, or it will take a substantially long time to deplete them as it can be replenished by nature. Statistics has shown that there is an increase in the investment of renewable energy over the pass few years, in 2007 more than $100 billion was invested in renewable energy (Renewables 2007 Global Status Report 2007, p. 16). Even China which has overtaken the United States as the world’s leading producer of greenhouse gases (cited in Joseph Kahn and Jim Yardley 2007 p.1). is switching to renewable energy resources(Renewables 2007 Global Status Report 2007, p. 8).

Green Washing in Petroleum Industry

...products. to preserve and expand their markets by posing as friends of the environment and leaders in the struggle to eradicate poverty the purpose of green washing is to preserve and expand their markets by posing as friends of the environment and leaders in the struggle to eradicate poverty. The history of green washing begins with research of environmentalist Jay Westerveld in 1986, in an essay regarding the hotel industry’s practice of placing green placards in each room, promoting reuse of guest-towels, ostensibly to “save the environment. Energy sector represents “biomass, coal, electricity, geothermal energy, hydrogen, hydropower, natural gas, nuclear power, petroleum, solar power, and power wind”, companies involved in generating energy. In this research paper, main focus is analyzing major energy industry components such as Petroleum industry, Nuclear power industry and Coal power industry, in order to explore the related Green Washing phenomenon. As an example for green washing, “Australian Federal Government’s Green Washing Campaign of nuclear power as a “clean” energy source and as the primary solution to reduce Australia’s green house emissions”, analyzed in this research. As an example in coal industry “ the clean coal” campaign recognized and analyzed as an green washing propaganda done by both government and private corporations. In petroleum industry, green washing occurs in two ways such as marketing campaign and research contributions. BP’s Beyond...
