Abstract: The present disclosure provides methods and systems for managing energy costs. A method for managing energy costs comprises: obtaining input data related to a property and one or more appliances associated with the property; predicting, based on the input data, energy consumption of the property over a time period; determining a set of candidate energy tariffs applicable to the property based on published utility data and the input data; determining energy costs of the property over the time period for each energy tariff; and identifying and outputting one or more energy tariffs in the set of candidate energy tariffs that reduce or minimize energy costs of the property over the time. The method may also include switching to the recommended tariff and adjusting the operation of the appliance(s) to minimize energy costs. The energy consumption of the property may comprise forecasted energy profile of one or more new appliances.

Abstract: Physical social actions are conveniently detected, characterized, and provided to a social networking system. This improves the user experience of the social networking system by more thoroughly recording the social actions of users occurring outside a social graph. This has the effect of extending an open social graph, which typically refers to social actions taken outside the social networking system but within a computer network, to physical social actions. By providing characterized physical social actions to the social networking system, the open social graph is extended to include physical social actions.
