Also, It focuses on sustainable emission targets including greenghouse gases, and aims at urban business and industry in solar and other renewable energy technology systems.
Background of Solar City Project ! Solar City Concept is firstly introduced 3 years ago, and confirmed formal IEA project in 1999. (Exco IEA task 30). ! Solar City project has implemented from 2002 for 5 years after preparatory period and during this time it has organized preparatory workshop 4 times.
