Hybrid power system solution application on smart eco-building in IndonesiaDeveloping countries need a lot of energy resources to help their economic growth. Those resources can be gain through making use of alternative energies to decrease the use of fossil energy which is known as un-renewable energy which is a real challenge for todays world. As one of developing country, Indonesia faces the same challenge. And, Indonesia has its solution by making se the alternative resources which can be obtained from the climate and phenomenon happened. Known that Indonesia is a tropical country which has its own advantages. Seen from the climate, when it is in dry season, it has abundant amount of sunlight. When it is in rainy or wet season, the intensity of rain is quite high. And, from the phenomenon happened, in the big cities there are a lot of pollutions and one of them is noise pollution caused by vehicles.Those conditions can be made as an alternative to produce electrical energy and new energy which is renewable by using heat of the sun, rain, and noise. Those three alternative resources can be converted to electrical energy through utilization of power electronic device. The implementation of this hybrid power plants can be applied on office building complex in Indonesia to overcome the burden of lights which are used in the buildings.
