Electricity production from modern renewable technologies (wind energy, solar energy, water power in small scale, and geothermal energy) is growing rapidly worldwide. In addition to the large-scale power generation, applications in the residential sector is also of interest which are classified into stand-alone systems (without connecting to the grid) and grid-connected systems. Zero energy building (ZEB) is a concept based on minimized energy demand and maximized harvest of local renewable energy resources. In this paper, the electrical energy consumption of a typical residential building is modeled. In addition to the electrical grid, the house is connected to a hybrid wind turbine and photovoltaic array together with a battery storage system. The cost of electricity purchased from the electrical grid was optimized to its minimum level. The results showed that, considering a load profile with 21.675 kWh of daily consumption, a 3 kW PV array with a 2 kW wind turbine and a 5 kWh battery could save 96% of the monthly electricity bill; from 2’377 to 66’960dollars. Excluding battery storage, this saving was reduced to 74%.
