1.
In a hydroelectric station the energy store of water at height is
gravitational potential
thermal
chemical
nuclear
2.
Tides are mainly caused by
wind
Earth's rotation only
the Moon's gravity
ocean temperature
3.
An advantage of tidal power is that it is
unpredictable
always available
cheap to build
predictable
4.
A disadvantage of hydroelectric schemes is
they flood large areas of land
they produce CO2 when running
they have no start-up speed
they need fuel
5.

49 kW
5.1 kW
490 kW
50 kW
6.
Pumped storage is used to
create fuel
store energy for periods of high demand
boil water
cool power stations
