The energy of the wind can be channeled into other forms of energy besides the energy used as an erosional agent. This is especially true of desert winds. Today, some desert wind is used to make electricity.
Wind velocity is affected by air temperature. When air warms and cools, it changes density, which creates air pressure differences that cause wind. In the desert, temperatures may range from 40º F at night to more than 120º F in the daytime. Because of this temperature fluctuation, wind is generally stronger in desert areas.
There are many windy areas in California. It is usually windier during the summer months when wind rushes in from cooler areas, like the ocean to replace hot rising air in California’s deserts.
In Southern California, the hot air from the desert goes up and out over the Coast Range, reaching seaward. When it cools off it descends and flows back toward the land and re-enters the desert through such loop holes in the Coast Range as the San Gorgonio Pass – the old Puerta de San Carlos – above Indio. The rush of wind through this particular pass is quite violent at times. For wind is very much like water and seeks the least obstructed path. Throughout the San Gorgonio Pass there are wind-eroded ledges attesting to the violent winds that pass through it.

- “Is Renewable energy an economically viable option for South Africa?” “Renewable Energy is a source of energy that is not exhausted when used.” “Economical means giving good value in relation to the resources used or money spent.” “Viable means capable of working successfully; feasible.” (Soanes, Hawker & Elliot et al., 2005) So in other words, is renewable energy an affordable and successful option for South Africa. Per year South Africa uses 1.3 % of the world’s total energy. South Africa’s main energy comes from coal, but one quarter of the coal we mine is exported to other countries....

- What is electricity. The term electricity means the force that makes electronics move from place to another. This is similar to the meaning of the engine as the force that moves a car or any mechanical machine. However, here it is explained as the effect not the physical movement. Throughout the ages, scientists have realized that electricity’s behavior can be predictable pattern when subjected to given conditions (Naiah & Kamakshaiah, 1995). What Electrical engineering. Electrical engineering is a field that deals with the applications the technology of electricity, such as generating, distributing electrical energy, and programing electrical systems....

- I. INTRODUCTION There is currently a challenge that the world is facing; the need for a convenient and affordable form of transportation that does not contribute to the destruction of the environment. There are many obstacles that make this a difficult task to achieve. Hybrid cars do use electricity as one of their main sources of energy, however the batteries used in these cars do not store enough charge to ensure the car’s ability to travel great distances. Because of this, hybrid vehicles have a second engine which runs on gasoline.... [tags: environment, electrical, energy, procedures]

- Electrical motors play an important role in today’s society, from powering domestic appliances like blenders to industrial equipment such as trains. It almost seems impossible to not use an electric motor in our daily lives. In the comfort of our home, electric motors will operate fans, refrigerators, and air conditioners to just name a few. Researchers are constantly looking for new ways to incorporate electrical motors in our lives. Electrical motors function by converting electrical energy into mechanical energy by using the energy stored in the magnetic field (Sarma, 1981)....

- Two Form of Renewable Energy The Earth’s oceans and winds are two sources of primary, renewable energy (RE). Historical records show the use of sails as a means of propulsion for watercraft on the Nile River in 5000 BC. On land, humanity converted wind energy to pump (move) water and mill (refine) grains. Windmills are thought to have developed in the East, in Persia, India and Tibet. The technology traveled west into Europe where counties such as the Netherlands, exploited the technology to pump water for land reclamation.... [tags: Wind power, Fossil fuel, Renewable energy]

- The United States needs a change in its energy sources. Oil, first of all, is a scarce resource that will eventually run out, and it also makes the U.S. depend on the political situation in other countries, as can be seen at the frequent changes in oil prices due to the political situation in the Middle-East. Alternative energy sources are an important issue to consider and nuclear energy is certainly the most controversial. There are currently 104 nuclear power plants operating in the United States, but the licenses of those plants will expire in foreseeable future, the first one already in 2013 and the last one in 2046 (Nuclear Energy Inst.)....

- Rhetorical Analysis: Writing in the Major. Common sense seems to dictate that I should be an engineer. My oldest brother is an electrical engineer for Cisco, my other brother is studying mechanical engineering at UNC Charlotte, my uncle is a petroleum engineer, and so is my cousin. But despite all this, choosing this discipline wasn’t an easy choice because I wanted to be a dentist, but after much consideration, I decided to study electrical engineering. Electrical engineering might be a relatively new type of engineering.... [tags: Engineering, Electrical engineering, Electricity]

- Renewable and efficient energy is an important field of research in the power and energy side of electrical and computer engineering. Renewable and efficient energy are needed in a world that is running out of resources and is becoming polluted. While it may seem like there isn’t any hope, scientists are developing new technology to aid a world in need. Recently, scientists have been able to make transportation more efficient by charging electric vehicle batteries with grids and by creating a new type of battery....

- Household Energy Optimization With resent load shadings and unplanned power outages in the country it becomes clear that the energy crisis have not been resolved to its full. As domestic houses still uses electricity without caution, high energy consumption remains a bigger issue. An investigation will be conducted to determine one household service that uses large amount of electricity and find alternative ways to reduce energy consumption 1 Introduction South Africa is one of the country that is facing a crises in the energy sector, with resent problems such as load shadings and unplanned power outages in the country, It’s is clear that South Africa‘s energy usage is at its most hig...
