Summer needs are quite location dependent. In Seattle, we run our A/C, but it takes far less power than somewhere farther south, heating needs in the winter are much higher. The car is also more efficient in the summer time, I use 15kwh commuting vs 22.5ish.

Of course, in the summer we have less hydro potential depending on rainfall, but a lot more solar. No one thing is or should be the answer.
