Mixed Bag
Is hydro energy or nuclear energy older?
Hydro energy is older.
Is nuclear energy a renewable or non-renewable source of energy?
It's a non-renewable source.
What is a disadvantage of Nuclear Energy?
- The same raw materials could be used to create nuclear weapons
- Risk of an accident that could cause damage to people and the environment
- The used uranium must be carefully disposed of to avoid contamination.
What is hydro electricity made from?
What is renewable energy?
Energy that comes from limitless sources like the sun, wind, water, and plants.
How does water actually make electricity?
Water falls -> turbine spins -> electricity is generated.
Are turbines used in nuclear power plants?
Yes! Steam turbines are used.
What is the waste created with nuclear energy?
Radioactive waste.
What is a disadvantage of hydro electricity?
- Impact on fish
- Can only be built where water already flows
- High cost to build dams
What is a disadvantage of renewable energy?
- Unpredictable (weather dependant energy production)
- High initial costs (Setup can be expensive)
- Large land requirements (Facilities can take up lots of space)
Name 3 sources of renewable energy.
- Hydro energy
- Wind Energy
- Solar Energy
- Biomass Energy
- Tidal Energy
Nuclear energy is produced by splitting a certain type of atom into 2 smaller atoms. What type of atom is it?
Uranium.
What is an advantage of Nuclear Energy?
- Does not use large amounts of land to generate electricity.
- Is a stable and consistent source of energy.
- Does not emit greenhouse gasses.
What is an advantage of Hydro Energy?
- Renewable source of energy we won't run out of.
- Does not emit greenhouse gasses.
- Reliable, as water always flows.How does solar energy work?
Solar energy is energy given off by the suns rays. It's harnessed by solar panels which store the suns energy. The stored energy is potential energy to be used on demand.
What is a disadvantage of wind turbines?
- Noisy
- Expensive to setup
- Wind doesn't always blow
- Dangerous to birds and bats
Nuclear energy creates __% of energy used worldwide.
10%. (If you got close I'll give it to you)
What is nuclear fission?
The process of splitting an atom to release energy in a nuclear power plant.
Hydro energy creates __% of all electricity used by Canadians.
59%. (If you got it kinda close I will give this to you)
How does wind energy work?
A wind turbine is spun by wind, which is connected to a generator. This generator converts mechanical energy into electrical energy.
What are the disadvantages of solar panels?
- Only collected when sunny
- Costs a lot to install
- Batteries store solar energy, but don't decompose. They will end up in a landfill when they stop working.Would you build a nuclear power plant in Alberta? Why or why not?
Up to individual answering.
It is! Heat is released from the nucleus of a uranium atom which is used to create steam, which then spins turbine blades.
Do you think hydro energy is a good idea in Alberta?
Up to individual answers.
If you had to build any type of energy source we've discussed so far in Edmonton, which would you choose and why?
Up to individual answers
