A method and system for determining a net energy consumption are described. Information is received descriptive of a power output generated by at least one source of renewable energy (1) associated with a user (100). Further information describes power consumption at premises (102) associated with the user and located remotely from the at least one source of renewable energy (1). A difference is determined between a value of the power consumption and a value of the power output. An energy bill may be generated dependent on the difference.
