Hello @jdc. Eucalyptus is not native, but if planted and managed correctly can be very beneficial particularly with agroforestry.

We indeed intend to be completely off-grid. Currently, we just have electricity, but plan to invest in solar power. There is so much sun here, so it´s an easy and cheap way to generate energy.

In terms of heating, we don´t have any and don´t really need it , as the winter is short and not too cold! The summer can however be hot, but the house with it´s 50cm thick walls is both warm in winter and cool in summer. :)
