Fossil Fuel/Nuclear Fuel + Extraction Flashcards
How is coal transferred to electricity
Burnt to release heat
heat is used to create high pressure steam
high pressure steam spins turbine
turbine is connected to generator
What are the positive of coal
will last for 100’s years to come
high energy
What are the negatives of coal
produces CO2
damage nature when mined for
How is natural gas harvested
fracking - cracking up big rocks to release it
What are the advantages to natural gas
emits less CO2 than coal or oil
uk has shale gas deposits
What are the disadvantages to natural gas
flammable
pollute water
What are the advantages of oil
converts small amounts to large energy
easy transport
What are the disadvantages to oil
creates lots of air pollution
How is energy gained from nuclear power
nuclear fission occurs to create energy
this energy heats water to super steam
then spinning a turbine connected to a generator for energy
What are the advantages of nuclear power
more efficient than fossil fuels
no harmful gases
What are the disadvantages to nuclear power
Nuclear plants are expensive and last 40 years
Uranium disposal is expensive
