  A smart city main objective is to provide a better living for the citizens by managing the resources both in a sustainable and cost-effective way to benefit the people at maximum., One of the key building factors of future smart cities is to generate its energy needs by clean renewables, the analytical approach results show that 37.5% countries in Asia & Pacific, 67% countries in Europe could reach 100% renewable energy generation by 2050. Some cities in North America and Canadian regions have already met the 100% renewable target. African countries could generate about 22 % of its energy by 2030. Further, a solution in four steps is presented to achieve the 100% renewables generation in building our future smart cities by 2050. Considering such an advanced energy system in smart cities, there is a strong need to strengthen the cybersecurity. A strategy with priority objectives to achieve a rigid cybersecurity system in the smart cities is also discussed.
