Home Are Network - nothing to discover..

Every house has a large number of electronic appliances that are able to gather information about the energy habits of the occupancies. These device are able can communicate each other through Bluetooth, Wi or usb. At the same time the possibility to have a broadband Internet connection, year by year, is covering the majority of the EU territory. These two factor could be joined together to reduce the energy consumption. Utilizing the HAN to meter the energy consumption and to increase the awareness of the people is one of the main goal of the smart grids. Many hypothesis on the development of smart grids and home area networks for energy optimization are been made during the last years. Basically a smart grid is a power grid with capabilities of self regulation and energy optimization. Smart grids can transmit data to buildings about energy tari , energy load and peak use. Unfortunately the implementation of a smart grid it required a large amount of capital and it is hard to draw a payback plan. The network and hardware technologies to implement energy e ciency house systems are available at low cost and could be really e ective. This is the reason why many companies are selling devices that can meter the energy consumption. Manyof these devices are able to turn on or o devices with a smart phone or from an outside house location using the internet connection. These networks could be used in a more extensive way for demand side management or to draw house pro le to target energy improvements measures.
