You won't really be able to power a house consistently with wind turbines because there are long periods (many days) without enough wind. No amount of storage can compensate for that, you'll need a generator or a grid tie-in.

The average capacity factor over the last year was about 30%, and they live in a rather windy location.

If you supplement that with some solar panels and a battery, a generator wouldn't have to run that often.
