The use of energy especially electrical energy is indispensable by the whole community. Very much alternative energy that can be produced from nature especially in Indonesia. One of them is the wind. The wind is an earned source of energy and does not require a large charge. The wind also includes a refurbished energy source and will not be in-leaned by time. Electrical energy can not be produced directly from nature, then to utilize this wind it takes a tool that can work and generate electricity well. The tool that can be used is windmill. The power of wind power electric is a power plant that produces electric power by the wind as its energy source. Electrical energy with wind power can convert wind energy into electrical energy using wind turbine or windmill. Electrical energy that comes from this wind uses battery or battery as an electrical energy storage tool. This windmill will capture wind energy and move the generator which will then produce electrical energy. This windmill can be improved its efficiency. To get the maximum power coefficient, one of which by using the eldest suds. This maximum power coefficient will increase the number of watts (power) generated so that it is to obtain a certain wattage of enough by using a fewer number of windmills.
