A walk in the Cotswold countryside to the slightly unlikely destination of a solar farm. The panels are in long lines, following the slope of the field, protected by strong metal fences, warnings of death and lines of cameras – but with not a single person anywhere to be seen. 
There is a public footpath through the middle and around the perimeter which hasn’t exactly been blocked but which avoids attracting any attention to itself – only the Ordnance Survey offers any confidence that it exists at all. I wonder whether to be a walker here is to be instantly suspicious, but the cameras do not turn, and even poking a camera over the fence prompts no reaction.
The solar panels stand in grassland which would be hard and inefficient to keep tidy with machinery. There is of course a simpler and long-established method for keeping parkland tidy – and so the impersonal modernity of renewable power generation is supported by some gently grazing sheep. It’s tempting to call it Combined Sheep and Power.
Along the way, the light and clouds keep shifting, the threatened downpour never quite materialising.
