what is a non-renewable energy source?
Will eventually run out it's not replaced at the used
what is a renewable energy resource
Will not run out he's being replaced at the same rate used
what are the main nonrenewable resources
Coal
oil
gas
nuclear
what are the main renewable resources available?
Solar
tidal
wave
wind
geothermal
biofuel
hydroelectric
what are the main advantages of using coal as an energy resource?
Enough available to meet current demand
Reliable
Cheap to extract and use
what are the main disadvantages of coal an energy source?
Will eventually run out
Releases CO2 which contributes to climate change
Release of sulphur dioxide which causes acid rain
what are the main advantages of using a nuclear fuel as an energy source?
Lots of energy from a small amount
Reliable
Enough available to meet current demand
No polluting gases
what are the main disadvantages of using nuclear fuel as a energy source
Waste is dangerous and expensive to sort
Expensive to shut down and run
what is the main advantages of using solar energy?
can be used in remote places
No polluting gases
no waste products
low running cost
what are the disadvantages of using solar energy?
Unreliable
cannot control supply
Set up is expensive
cannot be used on a large scale
what are the advantages of using tidal power? 
No polluting gases
No waste products
Reliable
Can produce large amounts of electricity
Low running cost
No fuel cost
what are the main disadvantages of using tidal power?
Harm habitats
Set up is expensive
Cannot increase supply when needed
Hazard for boats
what are the main advantages of using wave turbines?
No pollutants
no waste product
low running cost
no fuel cost
disadvantges of using wave turbines
unrelliable
dependant on weather
can't control suppply
set up is expensive
harm habitats
hazard for boats
cannot be used on large scale
main advantage of wave turbins
no polluting gases
no waste products
low running cost
low fuel cost
advantage of geothermal
no polluting gases
disadvantage of geothermal
set up expensive
availability in limited location
advantage of bio fueld
can be carbon neutral
reliable
disadvantages of biofuels
expensive
use land and water that can be used to grow food
advantages of hydroelectric
no polluting gases
no waste products
low running cost
no fuel cost
can be controlled to meet demand
disadvantage of hydro electric
expensive
dams can harm animals
