The cities of the future will see a lar e number of intelligent homes that can interact with their owners. In fact, things that were earlier considered science fiction are already coming to lie in smart cities such as Masdar in the United Arab Emirates, where an automated underground transport network fully fueled by solar power is already running circuits. With smart technology, the possibility of having huge savings on electricity and power is within our reach. Sensors are being developed so that street lights of the future will switch on only when you are close by. The smart technology in self-driven cars will enable you to save on gas and other non-renewable energy sources. In fact, smart cities will ai m to neutralize the use of fossil fuels completely. The cities of the future will have to adapt quickly to rapid technological advancements in IT and engineering. The gap between technological leaps is going to decrease over time. Technology will help bridge the current gap between the government and public in the cities of the future, given that IT and digitization will make these cities more open and social. Another thing that we can all agree on is that the cost of building in these smart cities is going to be considerable. An estimate can be derived based on the latest smart city developments in India. With the booming population, the Indian Prime Minister Narendra Modi is pushing to attract investments to fuel rapid development projects in the country.
