Which energy is transferred to which energy in order for hydroelectric power to work?

• Kinetic to GPE

• GPE to Thermal

• GPE to Kinetic

• GPE to electrical

Why is hydroelectric power renewable?

• Water is recollected by evaporation and rain.

• It's very clean and does not produce CO2

• It uses kinetic energy and GPE

• It ruins the landscape

What is not an advantage of tidal power?

• makes no polution

• expensive to build

• cheap to maintain

• more efficient than solar power

Where does tidal power schemes occur?

• river estuary

• in the desert

• in a pool

• in a beach

Describe the energy transfer that describes wave power the best.

• kinetic energy --> electrical energy

• Electrical energy --> kinetic energy

• nuclear energy --> electrical energy

• kinetic energy --> light energy --> electrical energy

What does the generators in wave power rely on?

• The crashing of the waves on the generator

• The back and front movement of the wave

• The sea creatures that the waves bring

• The sea salt of the waves

why is geothermal energy better than fossil fuels?

• it has a greater capacity factor

• it is more expansive

• it is emits less CO2

• it is easier to set up

what is one disadvantage of of geothermal energy?

• limited by geographical locations

• not avaialbe during the year because of the weather

• extreamly espansive

• not efficient

is coal a non-renewable recource?

• Yes

• No

What type of rock is coal?
