A lot depends on the seasonal variations in sun and wind in your area.
Here in southern Ontario, Canada, the good winds are in the period
October-May peaking in January. July and August are poor. Correspondingly
we have little sunshine in winter. So wind and solar go well together.

It seems that solar photovoltaic systems are very expensive but need
little maintenance and are durable. Wind turbines need regular
maintenance (rotating machinery, subject to fatigue loads, and they
vibrate). Also, everything depends on durability and reliability.
There are some makes of good machines, and some not so good, as well as
scam artists who seem to be attracted to the wind energy field.

Wind turbines that don't last and are often out of service can be even
more expensive than PV.

I wouldn't worry too much about climate change producing more clouds.

Noise is a factor, there are some poorly designed and noisy wind turbines

Site location and the local windspeed are very important for wind
turbines. Buildings and trees can seriously affect windspeed and
turbeulence with resulting metal fatigue and vibration. Good locations for
solar collectors are somewhat easier to come by. On the other hand wind is
more amenable to DIY than solar *electricity* - for those who know what
they are doing.

Solar thermal energy for water and space heating is should be fully
exploited before bothering about renewable electricity.

Conservation and efficiency are the keys to economical use of renewable
