This is the third iteration of a practical how-to handbook for local municipalities on the roll-out of sustainable energy measures. The first section focuses on governance and legislation (e.g. mandates, green procurement, institutionalising of sustainable energy concerns, etc.); the second on municipal sustainable energy initiatives (e.g. solar water heating, efficient buildings, sustainable transport, etc.); and the third on macro developments (e.g. smart grids, concentrated solar, ocean energy, etc.). Interactive icons assist in skipping between chapters (SEA, 2017).
