LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

The use of DG can be defined as an alternative to expand the capacity of the electrical system supply is being considered around the world. The use of small generating units‚ connected in a dispersed way at distribution/sub-transmission systems‚ can bring benefits to consumers and utilities‚ especially in places where there is deficiency of the electric energy transport system. However‚ the uncertainties involved in the planning and operation of system become bigger with the presence of DG. The impact

2.1 How Wind is Created. Wind is defined as air in motion. (1) When wind is being describe you first give the strength of the wind followed by the direction the wind is coming from e.g. extremely windy for a time‚ with strong to gale force and blustery west to northwest winds. (2) Wind is powered by the sun and by the rotation of the planet. Wind from the sun is caused by the uneven heating of the earth by the sun. The equator is heated much more by the sun than the poles. The hotter air expands
