Efficiencies of case-1 and cases 9-11 in winter

Winter Hydrogen input Hydrogen input Usable energy efficiency Used energy efficiency Usable energy efficiency Used energy efficiency 

Summer Space cooling Water heating Electric cons. Fuel cell run time Total Unused energy Usage of Usage of Surplus  

In this case, all energy requirements of the residential are supplied by electrical energy. 

Summer Summer energy requirements and results of case-12 are same as at case-10 (Tables VI. 19 and VI.20). For I. and II. law of thermodynamics, used energy efficiency values are lower than at case-8 but for II. law efficiency value is almost same as at case-8 (Table VI.20).
