Mr. Speaker, as I mentioned earlier, the problem is that that this 20 per cent was not simply dreamed up. It was a figure above which the diesel system became erratic or undependable. Now, if we had a system that provided 100 per cent of the power needs and we no longer needed diesel that would be one thing, but it would seem to me that a system that went up to 40 per cent, say between solar and some other system, would exacerbate the problem with the diesel system.
