Advantages of wave power

Renewable
Wont run out
Low fuel cost
no cardon dioxide
Doesn't cause acid rain

32

Disadvantages of wave power

Unreliable
Difficult to maintain and repair
Restricts shipping lanes

33

Advantages of tidal

Reliable - as tides can be predicted
Renewable
Wont run out
Low fuel cost
no cardon dioxide
Doesn't cause acid rain

34

Disadvantages of tidal

Difficult to maintain and repair
Restricts shipping lanes

35

Advantages of Biomass

Reliable
Renewable
Carbon neutral

36

Disadvantages of Biomass

Release carbon dioxide
Take up land which can be used for crops

37

What are the nine types of energy?

Kinetic, sound, light, thermal, electrical, gravitational potential, elastic potential (strain), chemical, nuclear

38

What is 'wasted energy'?

Energy that is transformed to either the wrong place or the wrong form

39

What is 'useful energy'?

The energy transformed to where it is wanted in the form wanted

40

If energy can not be created or destroyed why are we concerned with waster energy?

A lot of energy is wasted as thermal which dissipated and spreads out to the surroundings. This energy becomes so spread out it can't be reused usefully again.

41

What is the equation for work done?

Work done = force x distance in direction of force

42

What is the relationship between work done and energy transferred

Work done = energy transferred
