The wind turbine kit operates on a simple principle of turning mechanical energy into electrical energy. The wind blows the blades which turn a rotor shaft. The rotor shaft turns inside a motor which benefits from the magnetic field and converts that energy into electrical current. That current is then propagated down a set of wires and direct current form and must be converted to alternating current form in order to be used by a device or consumed by a battery for later use. The basic unit of energy that usually describes the performance of a wind turbine kit is the kilowatt. A kilowatt is equal to 1000 Watts. Kilowatts are units of energy that are recognized by an international standard called SI, which is the International System of Units. A Watt is equal to 1 Joule per second and is the basic unit of power that we talk about and renewable energy projects. This unit of energy was named after the Scottish physicist James Watt, who lived from 1736 to 1819. When you are looking into the wind turbine kit concept it is important to understand what a kilowatt is and how it relates to the amount of power that you will need to operate either the piece of equipment, and appliances your house, or your entire home. It is easy enough to find out what the kilowatt rating is of a particular electricity consuming device. You simply have to look at the plaque or the nameplate on the device and see what it says its maximum consumption, or rating is. This does not mean that it will consume this amount of energy all the time. It simply means that this is the most energy that it can consume. It is important to note that the wind turbine kits will be sized for a certain amount of wind. What I mean by that is if the kilowatt rating is 1 kW for example, that does not mean that you can expect to get 1 kW at of this device over a long period of time. Instead, what it means is that this is the instantaneous peak energy that you will be able to get out of the wind turbine. Also, keep in mind that the rating was made more than likely at a speed of around 29 mph of the wind. In conclusion, the wind turbine kit is rated in terms of how many kilowatts of power it will produce. While that is helpful in establishing differences between different options that you might have, it is not very instructive in terms of trying to understand how much energy will actually be able to get out of the device. So, let the buyer beware - make sure that you carefully look through the tables that and manufacture puts out and maybe even talk to them about how much energy you can reasonably expect over a period of time out of their product.
