A low speed wind energy conversion for home system in a developing country : design, technology and policies for rural electrification in Indonesia

Wind energy is a fascinating natural phenomenon that is interesting to study as, due to unpredictability it can either be a friend or cause disasters. However, with experience and through technology it can be tamed to become useful and have a direct influence on our daily life. Although wind energy can be harnessed and converted for many different purposes, the topic of this dissertation focuses mainly on the conversion of wind energy into electric energy, especially for village electrification programmes. Indeed, electric energy has become an essential source of energy for the modern world. Wind energy conversion systems (WECS) have long been known in most parts of the world, yet their implementation is not as popular as fossil fuel energy. The uneconomical cost of energy production, and uncertainty of wind energy availability are the main reasons for this. Nevertheless, when the oil crises, environment, and sustainable energy sources become issues, it should be looked into again. In addition, improved technology has made WECS more acceptable and reliable. Despite this, although it is free energy to be harnessed, in countries where the average windspeed is low the technology is less competetive than other source of energy. For some developing countries this technology may become appropriate. However, some modifications should be made until it becomes reliable and acceptable for the surrounding conditions. Technology, economy, policies and socio-cultural issues should also be taken into consideration
