Indonesian archipelago has ca.17.508 islands and 81.290 km coastline length. From 17,508 islands there are only five big islands, 992 islands populated and only 5,700 islands have names. The characteristic of small islands is poor resources, such as clean water and electricity supply. To build installation for clean water and electricity is very expensive. In addition, after the development, maintenance installation is difficult. In the state islands are like Indonesia, many handicaps to develop small islands because small islands spread in very large area from Sabang in Aceh Province to Merauke in Papua Province.

Indonesia, as a large and one of the most populous countries in the world, has problem to supply the energy needs, with more than 220 million people in Indonesia with diversity of jobs such as farmers and fishing. Indramayu and Cirebon regency with most people are dependant on paddy field and one of the main rice productions in Indonesia, long dry season occur every year. In the past, during the dry season the farmers used to use diesel pump machine to irrigate their plantation because the price of petrol-diesel was still cheaper. But since the global oil price increased more than USD 70 per barrel and government decreased subsidy to petrol-oil consumption, the farmers were difficult to irrigate their plantation as they have not enough money to buy petrol-diesel. Beside that many plantations are located in rural area which has no electric current from PLN (Indonesian National Electric Company). So, during the drought time many plantations in Indonesia have no productivity.

To anticipate that condition, we need to develop renewable energy such as solar, wind and water energy which could fulfill the need of energy consumption with cheaper price. One of the cheaper energies is wind energy or we may call it as free energy. Wind Energy as one of renewable energies, its kinetic and potential energy which should be changed to mechanic energy to fulfill the need of energy consumption by utilizing of the wind turbine which will generate to pump water from wells or rivers.
