Financial Tribune - The gradual expansion of green energy since 2009 has helped Iran save close to 800 million liters of water in 10 years.

Over the last decade close to 3.5 billion kilowatt hours of electricity was generated from renewable sources like wind farms and photovoltaic (PV) stations. For producing the same amount of power with natural gas, close to 1 billion cubic meters of the fuel would be required.
