Visualizing energy information on mobile devices

One of the efficient ways to reduce the carbon dioxide emission is the optimization of household customers' energy usage behavior. The suitable visualization of energy data, corresponding costs and tariff information on mobile devices depicts an important prerequisite to achieve this goal. The household customer is enabled to manage his energy usage in order to hold the optimal load an meet the optimal price. Energy data are acquired by a smart meter and transferred over wireless networks to a mobile device to provide the customer with relevant information about his current energy usage. Suitable visualization methods, specific for different tariffs, are identified and presented together with according specific technologies and methods for communication and data access.
