"Perhaps the nation's off-grid housing stock can be classed as an investment in a carbon-free future. Every off-gridder automatically reduces their energy and water consumption by up to 90% compared with a typical household. They live each day aware of the sun and the wind - dependent on the elements, and so closer to them."
He adds that off-grid living could help the government meet two of its main aims - more affordable homes and lower domestic carbon consumption - but that this would require a major change in planning laws. Well worth a read.
