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. :)
Nice. Solar if fine I suppose. I'm not a fan of it because of kW limitations and because of their quick degradation.
