Energy Resources Flashcards
What are energy
resources used for?
· Generating electricity
· Heating
· Transport
What are the three fossil fuels?
· Coal, oil and gas
What do the words
renewable and non-
renewable mean?
· Renewable – won’t run out
· Non-renewable – will run out
State the non-renewable
energy resources
· Fossil fuels
· Nuclear
State the renewable
energy resources
· Solar
· Geothermal
· Bio-fuels
· Wind
· Tidal
· Hydroelectric
· Wave
Which energy resources
release carbon dioxide?
· Fossil fuels
· Bio-fuels (but they also take it in when they grow so are carbon neutral
Which energy resources
are reliable?
· Fossil fuels
· Nuclear
· Hydroelectric
· Geothermal
· Tidal (can be thought as reliable as it is PREDICTABLE although it can only generate electricity twice a day
State the advantages
and disadvantages of fossil fuels
Advantages
· Reliable
Disadvantages
· Non-renewable
· Release carbon dioxide
· Coal and oil release sulphur dioxide
State the advantages
and disadvantages of nuclear
Advantages
· Reliable
· Small amount of fuel releases massive amounts of energy
· Doesn’t release carbon dioxide
Disadvantages
· Non-renewable
· Waste is radioactive for thousands of years
· Slow start-up time
· Expensive to decommission
State the advantages
and disadvantages of wind energy
Advantages
· Renewable
· No carbon dioxide emissions
· No fuel costs
Disadvantages
· Not reliable as dependant on weather conditions
· Some people don’t like the look or the noise they make
State the advantages
and disadvantages of solar energy
Advantages
· Renewable
· No carbon dioxide emissions
· No fuel costs
Disadvantages
· Not reliable as can’t make electricity at night
· Solar cells are expensive
- State the advantages
and disadvantages of
hydroelectric
Advantages
· Renewable
· Reliable
· No carbon dioxide emissions
· No fuel costs
· Short start-up time
Disadvantages
· Large scale schemes flood land which destroys habitats
· Large scale schemes build a dam which is expensive
State the advantages and disadvantages of geothermal energy
Advantages
· Renewable
· Reliable
· No carbon dioxide emissions
· No fuel costs
Disadvantages
· Can only be placed in volcanic areas (eg Iceland) · Building a geothermal power station is expensive
State the advantages
and disadvantages of tidal
energy
Advantages
· Renewable
· No carbon dioxide emissions
· No fuel costs
· Predicable
Disadvantages
· Can only generate electricity twice a day when the tide comes in
· Building a tidal barrage is expensive
· The feeding grounds of wading birds are flooded
State the advantages
and disadvantages of wave energy
Advantages
· Renewable
· No carbon dioxide emissions
· No fuel costs
Disadvantages
· Not reliable as dependent on wind conditions
· Disturb habitats of marine animals
· Hazard to boats
