Selection of Topic: Energy Crisis is a shortfall in or interruption to the provision of energy supplies. The planet is progressively marching towards a serious electric energy crisis‚ owing to an escalating desire of electric energy becoming greater than its supply. We have always accepted that the energy we make use of each day is not unrestricted‚ still we take it for granted. Coal‚ petroleum‚ electrical power‚ even water has inadequate availability. Nevertheless‚ we have not taken sufficient

Cinddy Solar energy Today‚ people make full use of solar energy and it benefits them a lot‚ especially in Spain and China. Due to their favorable conditions‚ solar energy has good practicality. It is much more convenient to use solar energy as people’s main energy resources than other renewable energy. The government gives financial support of solar energy which largely stimulates the growth of renewable energy. In addition‚ solar energy has a huge amount of influence on people’s life such

forces involved. Two of the main forces experienced are called potential energy and kinetic energy. Potential energy is the energy an object has depending on the position of it. For example the higher an object is the higher the potential energy is and the lower an object is the less potential energy it will have. Kinetic energy is also a main type of force that is involved with rollercoasters. Kinetic energy is the energy an object will have as it is in motion. There are many different types of

release of nuclear energy occurs when the nuclei of atoms are changed. Hydrogen and uranium are two kinds of matter used to produce nuclear energy. In a nuclear reaction‚ the tremendous binding energy inside a hydrogen or uranium nucleus is released. Nuclear energy is released during atomic fission‚ when uranium nuclei are split. It is also released during fusion‚ when hydrogen nuclei combine to form a helium nucleus. In fission and fusion‚ nuclear energy produces thermal energy‚ which is given

Energy systems Creatine Phosphate system The creatine phosphate system is an immediate energy system. ATP (adenosine triphosphate) is created without the presence of oxygen for short‚ fast bursts of power and energy. This is the first system used when performing any sporting activity. However this short burst of energy only lasts for a short moment in time for round about 10 seconds. Running events like the 100 meters sprint would be an example of using the creatine phosphate system. During the

Energy Conservation 1 Mitigation Strategies and Solutions: Energy Conservation Katie Shuker Axia College of University of Phoenix Energy Conservation 2 Energy conservation is the practice of decreasing the quantity of energy used while achieving a similar outcome of end use. This practice may result in increase human comfort‚ personal security‚ national security‚ environmental value‚ and financial capital. Energy conservation is a reduction or elimination of unnecessary energy use

Renewable energy is energy that originates from natural sources‚ which is a continuing and nonpolluting energy that is replenished due to its perpetual natural motion. These sources are commonly solar‚ geothermal‚ wind and tidal energies. Comparing different countries’ use of renewable energies -- in Portugal this year‚ close to 45 percent of its electricity will come from renewable energy sources (Rosenthal‚ 2010). This compared to 10.1 percent in the United States (U.S. Energy Administration

more than enough energy to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun’s energy and make it useable. Solar Energy is the energy from the Sun. The Sun is a big ball of heat and light resulting from nuclear fusion at its core. The nuclear reaction releases energy that travels outward to the surface of the Sun. Along the way to the surface the energy transforms so that by the time it is released it is primarily light energy. The two major

Energy is the fuel that runs the engine of the world economy. Believe it or not our need for energy is not primarily to run economies but intrinsically to create order in the world. Wind energy Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing‚ grinding grain‚ and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is an
