Smart grid: The Smart Grid is a combination of hardware, management and reporting software, built atop an intelligent communications infrastructure.

Wireless Power Transfer: Wireless power or wireless energy transmission is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous, or impossible.

Distributed generation: Distributed generation means power is generated locally, Avoids the losses that occur in transmission over long distances; energy is used locally, Supply is robust, but precautions are required to avoid the local system feeding back the power to grid during maintenance
