Wind turbines and solar panels are already being installed and, being unfamiliar, causing controversy over their visual effect.

We will later be able to accept these intrusions but there needs to be some planning thought to reduce the impact.

A single wind turbine can be a pleasant statement; I like the one in Glynde with the post of an early windmill nearby. If there were more of this windmill, a preservation society would be busy restoring it. Will anybody, later on, be looking after the defunct turbine?

Wind turbines across plains and hillsides may possibly look better if arranged in closer groups, and also when out at sea.

During the Second World War, huge hollow concrete barges were formed and towed across the Channel, then sunk to form Mulberry Harbours. This system would be an ideal way of setting up six or nine wind turbines in a ring with similar concrete sections as foundations.

Wiring connections and prepared platforms for turbine masts would provide great economic savings.

The visual impact of groups of turbines out to sea is neater than a wide spread of individual ones.

Solar panels positioned above roof slopes are not pleasant to the eye. If they were lower and part of the roof covering, they would be more acceptable.

It is up to architects to plan new buildings with slopes orientated towards the sun, using integral solar panels blending with the roof.

There are swathes of ground below high-tension power lines that supply rural areas. Where these lines pass through woodland, the trees and shrubs have to be kept low and in check. These areas would provide secluded sites for solar panels on frames, as now used on some farmland.
