Adequate insulation in construction is increasingly used with strict regulations for new buildings, repairs and reconstruction projects, although they do lag behind the UK by about five years.
There are some innovative and successful projects, however. The only fresh water available is rain that seeps through to valleys on the southern end of the island and heads for the sea as small streams or duits, as they are called. There is a reservoir in the centre of the island, but it cannot store enough water to last the summers. A bright spark realised that all this rainwater was running off and wasted at sea. Now, each duit has a pipe buried in its bed, and a pump at the bottom, recycling the water back to the top or, if feasible, into the reservoir. The process is completely invisible to the holiday walkers.
There is a strong focus on setting priorities and goals for sustainable and renewable systems to make Guernsey greener, with increased interest in solar power, high-efficiency building materials and energy conservation in all its forms.
Are there any lessons to be learned from all this? Probably tricks could be learned from each other, but it appears that adapting to one's own special circumstances, and having an administration and support group who are dedicated to a sustainable and green community, are essential.
