1. What provides some of the most favourable conditions in the world for the utilization of tidal power?

2. Why is future exploitation of the UK's tidal energy potential unlikely?

The unusually high tidal range along the west coasts of England and Wales provides some of the most favourable conditions in the world

Unit 7. Tidal Energy

for the utilization of tidal power. If all reasonably exploitable estuaries were utilized, annual generation of electricity from tidal power plants would be some 50 TWh, equivalent to about 15% of current UK elec­tricity consumption.

Feasibility studies have been completed for two large schemes: Sev­ern estuary (8600 MW) and Mersey estuary (700 MW), and for small­er schemes on the estuaries of the Duddon (100 MW), Wyre (64 MW), Conwy (33 MW) and Loughor (5 MW). Given the combination of high capital costs, lengthy construction period and relatively low load fac­tor, none of these schemes is regarded' as financially attractive² in present circumstances. Future exploitation of the UK's tidal energy potential is unlikely unless there is a substantial increase in the cost of electricity generation from fossil fuels.

• Complete the following sentences using the information from the texts.

a) Australia's best tidal energy resources are located (in the north­east, in the north-west, in the south-east).

b) The 20 MW Annapolis Tidal Power Project is located at Annap­olis Royal (on the Bay of Fundy, Nova Scotia), where the tidal range is (between 4.4 and 8.7metres, between 4.8 and 7.8metres, between 3.4 and 7.4 metres).

c) The Kislogubsk pilot tidal plant (400 kW) was commissioned in 1968 near Murmansk (on the Black Sea, on the Barents Sea, on the Laptev Sea).

d) The unusually high tidal range along the west coasts of England and Wales provides some of the most favourable conditions in the world for the utilization of (thermal power, nuclear power, tid­al power).
