Whaaattt?

Yes the house is the concrete bit.

 

Stone here @pete and timbers and tiles in and on the roof!

 

Its a solid structure, if you just put rows of panels in a field and want it to last 20 30 years you cant just put it on something flimsy, its going to need a base of some kind.
I'm referring to solar farms, massive fields of panels.

 

But that suggests the land is finished forever, its just never going to become farm land again.
Its lost.

 

There lies the problem, earlier windfarms can't always be used for future farms due to spacing needed for larger more efficient turbines, plus significant upgrades to the grid are needed. Just because an energy company is granted a permit to build and generate renewable energy, does not mean they will be granted again 25 years down the line on the same area of land. There is numerous on shore windfarms that will be decommissioned, with probably a good percentage of them leaving huge masses of concrete buried in the ground.
