Topic 1 - Energy Flashcards
What are the advantages of fossil fuels?
- Reliable
- Short start-up time
- Good to meet basic demand
What are the disadvantages of fossil fuels?
- Pollution(CO2, SO2)
- Fossil fuels will run out
- As fossil fuels run out they become more expensive
What are the advantages of nuclear power?
- Reliable
- No CO2 or SO2
- Lots of energy released
What are the disadvantages of nuclear power?
- Radioactive waste is hard to dispose of
- Radioactive materials are dangerous
- Expensive to decomission
- Expensive to setup
How are biofuels carbon neutral?
They are carbon neutral becuase they took in as much CO2 during their life as released when burning.
What are biofuels?
Plant and animal waste.
What are the advantages of biofuels?
- Carbon neutral
- Renewable
- Provides jobs

- Still requires burning
- unreliable
- Requires more fuel to release as much energy as fossil fuels
- uses crops for fuel instead of food
- requires lots of water to grow
- Uses farm land
What is the difference between solar panels and solar cells?
Solar panels heat water, solar cells convert light into electrical energy.
What are the advantages of solar power?
- Once setup energy is free
- No CO2 or CO2
- Can be used in remote places
- Renewable
What are the disadvantages of solar power?
- Initial setup is expensive
- unreliable
- only works during day
- requires lots of land
What are the advantages of wind power?
- No CO2 or CO2
- wind is free
- can be used in remote locations
- land beneath turbines can still be used.
- Works at night
What are the disadvantages of wind power?
- Unreliable
- Noisy
- ugly
- not very efficient
What are the advantages of Hydroelectricity?
