Cornwall has a long history of heavy industry and is proud of its visible mining heritage. Throughout Cornwall, derelict engine houses can be seen inland and on cliff tops from a great distance. The engine houses vary in size, but they tower above the ground with a stack or chimney up to 30m high. A geothermal power plant will be a fraction of this height, can be painted to camouflage the main structures and screened with native trees and shrubs. GEL are keen to ensure power plants do not detract from the existing vista that is peppered with the relics of past industry.
