Professor Michael McMahon:

I will add one thing on that. A little like the discussion we had with Deputy Doherty about the housing market and investments in that, in some of these areas, especially now as energy costs have gone up, many countries are trying to do this and so there are supply constraints emerging on, for instance, the insulation and the highest-quality materials we need to in order to do it. There is also the number of qualified people in this country who could roll out a widespread package like that. In theory, however, these are sensible investments from a long-term point of view.
