Those are great points especially the point about long life mines, they would be the most cost effective. I think the biggest issue has been cost, the batteries and solar panels and wind generators have come down in cost substantially and they are also now a proven technology. The domonstration projects have shown that they work and now I think you will see a big move towards these green initiatives in mining and powering remote communities. I like your point about the environmental impact as well, I also have stock in some juniors and a big part of the process is the environmental assessment, it would seem to me that this would assist in getting the permits.
