Interesting article. I haven't used the hut and agree he increase is neither here nor there. I'm sure the architects have got it covered in their plans but is there any scope for solar panels and/or wind turbine technology with associated grants if any. As users of the hills and mountains we all need to see the bigger picture and apply sustainable energy to facilities. Otherwise what's the point of complaining about wilderness areas being subjected to the large scale march of wind turbines and pylons if we can't demonstrate alternative and sensible micro generation. The example of island energy schemes such as that on Eigg can surely provide guidance on what is possible.
