    Desert Winds and Electrical Energy 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

    wave power as a renewable energy sources and specifically details three types of generators that makes that conversion possible. These three generator types are: permanent-magnet tubular linear generators, hybrid air-wave turbine generators and wave tunnel generators. One of these types of tidal generators is a permanent-magnet tubular linear generator , also known as a linear buoy generator. A linear buoy generator converts the “linear motion of waves into electrical energy” (A 2392). There ...

    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

    The energy demand all over the world is expected to be 28 terawatts by 2050, which can lead to increase of energy consumption patterns and greenhouse gas production. (P.Alivisatos et al. 2005) One of the most significant issues the industrialised world is facing today is the energy challenge, issues associated with energy production, storage and reducing consumption of energy use. The use of energy has reason to rise over time due to an increase in the world population and the discovery of new technologies

    For electricity to be generated there is a need for a source of energy. Some of these sources will include Wind, liquid water forced to move at high velocity or steam projected at high pressure. The energy harnessed from these sources is used to run large turbine devices which in turn run attached generators that produce electricity that is the extracted and distributed. These sources produce mechanical and kinetic energy that is extracted by massive turbine devices that have blades spinning at great

    The current worldwide electric generation is estimated to be about 20terra-watt hours [1]. Almost 68% of the electrical supply is generated by using fossil fuels as the raw material, nuclear accounts for 14%, hydro 15% and the remaining 3% is from renewable resources. The worldwide electrical demand is going to double by the mid-century and triple by the end of century. As the demand will increase so will the generation, which means more fossil fuels will be used which in turn will create more environmental

    Since the early ‘90s, the electrical energy sector has undergone profound and dramatic changes. More and more countries moved towards the deregulation of their energy sectors, from a regulated and monopolistic industry to one were the market forces of supply and demand determine the unit price of electricity. The first case of energy sector deregulation in Europe was recorded when the United Kingdom with the Electricity Act of 1990 created the Electricity Pool for England and Wales. Norway soon followed
