The objectives of this study are to find the best way to calibrate data that are collected from the energy maps of Turkey and take advantage of alternative electric energy source in construction projects. To achieve these goals, renewable energy maps of Turkey were collected. Four types of energy maps such as solar, wind, geothermal, and wave energy were utilized. Cost effectiveness was proposed for the construction projects that have a total cost of more than a million dollars. Thus it is considered that alternative energy maps in the study could be utilized for construction projects instead of spending too much money using the traditional methods for on-site energy generation. This study is just a research that aims to figure out renewable energy availabilities on construction site(s) and it is also proposing that construction projects need much more research about green energy; thereby the real engineering methods will find their meanings.
