Solar is not great for heating in winter because solar produces very little energy in winter (which is literally the reason why winter is cold in the first place: less solar radiation).
So even if you have solar, unless your installation is massively oversized you generally don’t have spare every in winter for heating.
Small consumer wind turbines make sense only in limited cases, and I say that as someone who had been building some. Because places with a strong constant wind are limited and generally this is not when houses are built.

No, what we need is seasonal batteries. A way to store the surplus or solar energy in summer to use it for heating in winter.
Wood is exactly that, solar energy stored in a stable chemical form that is easy to use.
