Wind energy has been used in some countries for a long time, but disappeared when the widespread use of fossil energy technologies. Utilization of wind energy that extends back when fuel prices soared, but receding back when fuel prices dropped in 1985, but the system competitive. The use of highly competitive systems as alternative energy supply continues to grow.
Small turbine applications outside the network (off-grid) power is directed to water pumping in rural or farm / ranch, while large wind turbines connected to the network (grid-connected) directed to the generation of large scale. Wind resource is a basic consideration in the design, application and feasibility of wind energy systems.
Utilization of wind energy in Indonesia today is directed to rural electrification, and contribute as alternative energy in the future. Wind speed information suggests that the use of small wind turbines is the potential, while the use of large wind turbines is also possible. With the continued development of wind energy technology and the growing need for energy, wind energy systems will be increasingly competitive.
