Electric Power Voltages and Frequencies (Hertz) Around the World

Categories: Commercial Wind Power

Countries around the world operate with different voltages and electric power frequency commonly know as Hertz after Heinrich Hertz, who worked from 1889 until his early death in 1894 as a professor at the University of Bonn. Before coming to Bonn, Hertz had already demonstrated the existence of electromagnetic waves experimentally and therewith proved the "Maxwell equations" of electromagnetic theory. These equations, unchanged to this day, are known as the basics of the description of all electrical and magnetical phenomena. One fundamental ... Read More

Siemens Closing In On Major Players With $900M In Wind Turbine Contracts

Categories: Wind Power News

Line of Offshore Wind Turbines

    [ad] By Camille Ricketts - Engineering giant Siemens has made its presence felt in the wind business, winning six contracts to build 565-megawatts worth of wind turbines, valued at more than $900 million. About 250 of the turbines will be installed in Ontario Canada, with the other 750 (enough to power 170,000 homes) destined for wind farms in California, Oklahoma, Washington and Wyoming (for a project owned and operated by Duke Energy). Having first entered the wind market five years ago, Siemens is steadily climbing ... Read More

Solar Panels

Alternative Energy - SOLAR POWER (solar panels) [ad] Solar energy is one the most resourceful sources of energy for the future. One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man. However, about 1/3 of this energy is either absorbed by the outer atmosphere or reflected back into space (a process called Albedo). Solar energy is presently being used on a smaller scale in furnaces for homes ... Read More

Plans to build a windmill

Instructions to build your own windmill. Windmills are rather simple machines powered by wind energy. Wind turbines make use of wind to turn rotating blades. In earlier times, windmills were used to produce energy to grind grain and pump water. Nowadays, windmills are used to turn wind energy into usable (electricity) energy by making use of its rotating blades. Windmills which created centuries ago can be constructed with a set of simple tools, materials and know-how. Today’s windmills are very high tech and are made from ... Read More
