Wind Power

Wind power has been an effective energy source for nearly twenty years. At the end of 2007, worldwide capacity of wind-powered generators was over 100 gigawatts. It accounts for upwards of 19% of electricity production in countries like Denmark.

What is Wind Power?

Wind power is the transformation of wind into energy, usually in the form of electricity. Wind technology brought the Nina, Pinta, and Santa Maria to North America in the 1400’s and ran Dutch wind mills, so it is well-established in terms of its potential. Farmers have used wind power to pump water. Human beings have known about the power of wind for a long time and have been using it for thousands of years.

Broken Light Bulb

The incandescent light bulb was invented in about 1802. Practical incandescent light bulbs were not invented until 1878 when tungsten was used for the filament. In many respects the technology hasn’t changed much after the initial refinements. First let me explain how an incandescent light bulb works.

How Incandescent Light Bulbs Work

Electricity goes through a thin strand of material called a filament. The material gives off light after it is heated in a process called incandescence. The filament is tightly would like a spring so that there is more length to give off light. Being enclosed inside a glass shell protects the filament. The excessive heat produced by the electricity would cause the filament to burn up if it were exposed to the oxygen in the air. Incandescent light bulbs are usually filled with an inert gas such as nitrogen to prevent the filament being exposed to oxygen. To better project the light outward a pear shaped bulb is usually used.
