Case Study of Hybrid Wind-Solar Power Systems for Street Lighting

Global warming, pollution and sky racketing prices of the conventional energy sources have put the governments and the power industries under and increasing pressure to invest in the renewable energy sources. In Lebanon, the demand for electric power is growing year after year, taking into consideration that the imported fossil fuel is used in the generation of about 90% of the needed power and the tremendous power crisis that the country has been living through for the past several years, the idea of working on the implementation of renewable energy sources is becoming more appealing. This research consists of a complete study on replacing the highways lights powered by conventional polluting energy sources by lights powered by hybrid Wind-Solar renewable energy systems. The results of this research show that the application of the hybrid power system will ease greatly the power crisis in Lebanon, cut the electricity bill for the street and highways lights and reduce the pollution level caused by the use of conventional sources of energy.
