Large ground mounted PV arrays DO shade the ground beneath them and render it less usefull, or entirely uselss for agrigculture. This argument does not apply to arrays placed atop buildings, these do not remove any ADDITIONAL land from farming, beyond that ALREADY taken up by the buildings.Pepperman wrote:------I fail to see how renewable energy impacts farming, fishing or air transport.

Some types of hydroelectric plant do interfere with fishing in that they prevent fish from returning to the upper reaches of rivers to spawn. This largely affects sport fishing, rather than bulk food production.
Large wind turbines would interfere with air transport if too close to airports, this is normally prohibited. There are plenty of sites not near airports.
Rural wind turbines require access roads and this reduces available farmland, but only very slightly.
In general Renewable have fewer adverese effects than fossil fuel plant.
