Good Stewardship? A Challenge to Churches

For some time this possibility for older churches seemed to have the insuperable problem that solar panels would never be allowed on a Grade I or II listed building. No longer! There are panels on Grade I listed churches and even on a Cathedral. Hence the poem/challenge below

Good Stewardship?

Every day,

powerful rays of the sun

rain down

on a multitude,

of passive,            

south-facing

church roofs.

Could those barren acres

be converted into

fruitful energy providers? 
Thus, of good stewardship, 
rendering proof.
