I agree with the first part, but being consumption aware brings you only so far. As an example I'll be moving into an A++++ isolated, triple glass, gass-less home using an efficient heat pump to convert 1x electrical energy into 5x heat energy using earth heat. Even then, we'll probably be at your consumption level (ballpark), for heating and ventilation alone. Many places on earth just won't work without heating (or AC), no matter how 'consumption aware' you are. Curious as well to how you came to your last remark.
