Abstract
Over the past fifty years, several proposals have been advanced to harness the exceptionally high tides of the Bay of Fundy region for the generation of electricity. Each proposal, however, has been rejected on the grounds that it was uneconomical. Changes in the world energy supply, culminating with the Arab oil embargo in the 1970s, have however stimulated serious reconsideration of tidal powerpower2. That reconsideration has included examination of the environmental consequences of a large-scale tidal energy facility constructed in the Bay of Fundy in Nova Scotia.
