  • Geothermal Energy
    866 words
    I. Overview of Geothermal Energy Geothermal energy (from the Greek words geo [earth] and therme [heat], thus 'earth heat' energy) is a domestic energy resource with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). Heat is brought up to near the surface by thermal conduction (diagram: B) and magma. This heat heats ground water to form hydrothermal resources (natura...

  • Second Type Of Passive Solar Energy
    614 words
    Solar Energy The Word solar comes from the Latin word solaris, which means sun. Solar Energy is the act of catching light from the sun and converting it in to energy. This is not new many ancient people used solar energy. The Egyptians, the Greeks, the Romans and American Indians used the sun to warm their homes. There are two types of solar energy, passive and active. If no mechanical devices are used in a solar energy system it is called passive solar energy. This is an appealing energy altern...
  • Energy In Bio Fuels
    694 words
    The first question, which I must ask in order to write this essay, is, what is energy Energy gives us the ability to do thing. Everything in the world needs a supply of energy, and so energy is used to make things work. The word energy is taken from the Greeks and means the work within and nearly all energy originally came from the sun. The main type of energy used in the world is fossil fuel. Fossil fuels are called non-renewable because they are the remains of plants and small dead animals, wh...
  • Energy Per Unit Body Mass
    467 words
    ENERGETICS OF BIPEDAL RUNNING 1. METABOLIC COST OF GENERATING FORCESummarySimilarly sized bipeds and quadrupeds use nearly the same amount of metabolic energy to run, despite dramatic differences in morphology and running mechanics. It has been shown that the rate of metabolic energy use in quadrupedal runners and bipedal hoppers can be predicted from just body weight and time available to generate force as indicated by the foot ground contact. We tested whether this link between running mechani...
  • Increased Use Of Renewable Energy
    1,104 words
    Renewables, the Energy Source for America's Future When many people thing of the United States, they envision a land of freedom, prosperity, and wealth. However, environmentalists see a different land, one containing six percent of the world's population, and yet producing twenty-five percent of the world's pollution. This is because much of our prosperity is direct result of our exploitation of fossil fuels. They provide us with about ninety-three percent of the energy we consume. For this reas...
  • Direct Use And Ground Source Heat Pumps
    677 words
    GEOTHERMAL ENERGY Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and simila...

    ENERGY CONSUMPTION CRISIS Energy is important to our nation for many reasons. It is a key economic driver. It offers new market opportunities for business. Providing energy to our nation has been an exciting challenge in recent years. Many changes have been constant throughout that period. The past tells Americans that predicting the specifics of the energy future for our nation with great accuracy would be unlikely. Americans get their energy from different types of resources. With all the diff...
  • Electric Energy In The Colombian River Basin
    1,501 words
    Energy Flow Systems Richard White's Organic Machine, and William Cronon's Changes in the Land, both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White's thesis is to examine the river as an organic machine, a san energy system that, although modified by human intervention, maintains it's natural, its "unmade" qualities. White emphasizes on energy because it is a useful concept that can be easily...
  • Solar Energy A The Sun

    The sun is the source of energy for all living things. Plants use solar energy to carry out photosynthesis. Animals that eat the plants also depend on the sun for energy. Even the fossil fuels that are burned came from the sun, in directly, since the living things decayed into fossil fuels used solar energy. A. The sun produces solar energy"^3 then plants absorbs the solar energy for photosynthesis "^3 Animals eat the plants"^3 animals get energy"^3 human eat the animals and plants therefore get...
  • Electrical Energy
    1,111 words
    The energy that is used today comes from fossil fuels, which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar, hydroelectric, geothermal and wind energies can be used, to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses. Hydroelectric energy ca...
  • Growth In Energy Intensity In Industrialized Countries
    599 words
    The environmentalist view of the energy intensity is based on the legacy of the I = PAT equation in which environmental Impact equals Population, multiplied by Affluence, and further multiplied by Technology (Earth Report 2000: Revisiting the True State of the Planet. 1999). The further desegregation of this formula implies that energy intensity can be looked upon as an integrative variable describing the impact of both technology and affluence. Bruce et al. (1996) argue that intensity is invers...

    Alternate Energy Resources As most people know our energy supply is slowly running out. We are using energy sources that either pollute the air, take up natural resources or cause damage to other forms of life. Today, we are working on other forms of energy that do not pollute or cause harm to the environment. Here are some: Magnetohydrobynamic Power Magnetohydrobynamic power is where created by plasma. One way is for gases are heated to really high temperature to where the form plasma. They are...
  • Energy From Fossil Fuels
    478 words
    Entropy and Pollution The substances that we as human beings classify as 'pollutants' have always been present on the planet, because the earth is a closed system. The reason that these materials cause a negative impact on the environment, therefore, is not that they exist, but that they have been dispersed throughout the world's ecosystems in a very disordered fashion. To illustrate this, two pollutants of major concern will be considered, carbon dioxide (CO 2) and sulphur dioxide (SO 2). CO 2 ...
  • Energy Consumption The U.S.
    378 words
    ENERGY CONSUMPTION The United States of America uses more than one fifth of the world's resources. Energy consumption doubled between 1952 and 1972 and although consumption has slowed it continues to rise at an alarming rate. In the 1940's the U.S. A exported fuel but by 1952 it was importing large amounts of oil and coal. Since 1981 the cost of fuel imports has been over 75 billion a year. The U.S. A is now being forced to mine oil and natural gases in places like deep-sea basins. Only 6% of Am...

  • Current Source Of Energy
    651 words
    As we move towards the future we are beginning to realize that many of the processes that we use in our everyday lives are becoming outdated and harmful not only to us, but also to the environment that we live in. We are looking to make changes in our lives to help not only ourselves but our future generation, thus I believe that we must now start taking these steps. We must start to use other types of energy to ensure that this planet has a future. We need to move away from the current methods ...
  • Community Versus Independent Use Of Energy
    1,067 words
    The production and use of energy with respect to the technical, organizational, and cultural aspects during the Middle Ages and the 19th and 20th centuries provide both similarities and differences. The technical differences are a matter of source of energy. During the middle ages, energy came from water, while during the 19th and 20th century it came from electricity. Organizationally speaking, both time periods show a dependency of the source of energy while efficiency of standardization also ...
  • Amount Of Useful Energy
    275 words
    Second Law of Thermodynamics vs. Evolution According to the second law of thermodynamics, when energy is converted from one form to another, the amount of useful energy decreases. In relation to the theory of evolution, this law is not contradictory. The second law of thermodynamics is not relating to energy within living things because living things retain energy from the sun. The sun produces concentrated energy, which increases entropy. To maintain orderly structures, living things use this e...
