The idea of "smart homes" has really taken off in the past decade.. In the case of smart homes, a person will have access to everything in their home (appliances, devices, utilities, etc.) through Bluetooth and wireless internet. In the future, this will extend to the point where the "Internet of Things" (IoT) becomes a reality.The concept refers to the way in which the digital world and real world will become intertwined like never before. On the one hand, this will be driven by the trillions of devices, sensors, and geo-tags that connect countless points in the real world to the internet. On the other, people's experience of the real world will be increasingly mediated through augmented reality, virtual reality (AR/VR), and the help of artificial intelligence. For IoT to be a necessity of life we need constant supply of electricity with no redundancy. This will be sufficed by: energy concerns of the future will be moving away from the centralized grids and become more localized. By 2050, cities will have distributed power stations that run on solar, wind, piezoelectric, geothermal, biomass, and other "green" sources of energy. These localized centers will provide power for a specific area, and large buildings are likely to provide their own power using built-in solar arrays, turbines, and biofuel generators.
