Claim:
1. An energy management apparatus comprising: a power generation estimator configured to estimate a power generation amount of a power generation apparatus using a renewable energy; a demand estimator configured to estimate an energy demand of an electrical device of a customer; a creator configured to create an operation schedule of the electrical device based on the estimated power generation amount and energy demand; and a controller configured to control the electrical device based on the operation schedule, wherein the demand estimator comprises: a storage configured to accumulate load data representing a result of a load of the electrical device; an extractor configured to extract a plurality of load patterns including a plurality of different load data from the accumulated load data; and a calculator configured to calculate a weight based on a predetermined standard for each of the extracted load patterns, and the creator comprises: a simulator configured to simulate, using a predetermined algorithm, an evaluated value of each operation schedule based on the extracted load pattern and the weight of the load pattern; and a scheduler configured to create the operation schedule based on the evaluated value, and wherein the extractor extracts a plurality of load data for a predetermined period before and after the same time of a past day as a current time, and the calculator calculates the weight by computing differences between load data up to the current time of a current day and the extracted load data such that the weight decreases as the differences increase.
