A

Most part of the world are not suitable, expensive to build

40
Q

What energy store is tidal energy?

A

Kinetic energy

41
Q

What are some uses of tidal energy?

A

Electricity generation

42
Q

What is the relative power output of tidal energy?

A

Potetially very high but hard to harness

43
Q

A

Electricity generation and heating

47
Q

What is the relative power output of solar energy?

A

Dependant on weather and only available during daylight

48
Q

What are some advantages of solar energy?

A

No harmful emissions, low maintenance and can reduce energy bills long run, renewable energy resource

49
Q

What are some disadvantages of solar energy?

A

Expensive to build, only available during daylight

50
Q

What energy store is water waves?

A

Kinetic energy

51
Q

What are some uses of water waves?

A

54
Q

What are some disadvantages of water wave energy?

A

Tidal barrages destroy habitats for fish and marine life, difficult to make wave machine big enough to produce large amounts of electricity

55
Q

Why are some energy resources more reliable than others?

A

Because some are reliant on factors that cannot be controlled by humans such as weather and are inconsistent in producing the needed amount of energy.
