Abstract
The economic and environmental problem due to fossil fuel usage as an energy source is urgently needed to be solved. In countries like Indonesia, which is located in equatorial area, the abundant source of renewable energy is one of the solutions that can be utilized to counter this issue. However, 89% of total electricity consumption in Indonesia use fossil fuel, while public sector consumed 6% of Indonesia’s total electricity consumption annually. Converting some of the public sector source of electricity usage, streetlight for example, can help the government a great deal. Although some of the streetlights in Indonesia have already been remodeled to PV streetlights, problems arise when the inconsistency of sunlight happens. Combining PV and Wind turbine as electricity source is an alternative to solve this issue, and is becoming a trend nowadays. Due to small wind speed in Indonesia, finding the best turbine type is a major obstacle for developer. This study’s aim is to offer the best type of wind turbine in urban Indonesia’s area, and to recognize the proportion of PV and wind turbine energy support in the system. Based on ANSYS CFD 17.0, the best wind turbine’s geometry for urban area in Indonesia is Savonius Wind Turbine with twist angle of 90° and aspect ratio of 2. Based on Indonesian’s street standard, the streetlight is 3 m height, using 10 W of LED light. To support this light, the source is using 160 Wp PV systems, combined with a Savonius Wind Turbine of 2.5m heights and 1.25m diameter. The average energy given by the PV panel is 214,1 Wh, while from wind turbine is 5,8 Wh.
