are biofuels renewable or non-renewable

renewable

10

are tidal waves renewable or non-renewable

renewable

11

is geothermal renewable or non-renewable

renewable

12

is wind renewable or non-renewable

renewable

13

how is oil obtained

traditional drilling and pumping methods

14

how is natural gas obtained

it is a product of decomposed organic matter burned over time. it flows easily up wells to the surface.

15

how is coal obtained

surface or underground mining

16

how is nuclear obtained

created from the release of energy from nuclear reactions, usually from uranium or plutonium. byproducts are radioactive.

17

advantages of using nuclear

small amount of fuel needed
low carbon emissions
cheap running costs

18

disadvantages of using nuclear

nuclear waste highly radioactive
storing nuclear waste is expensive
decommissioning power stations are expensive

19

how is HEP obtained

trap flowing water then release it under greater pressure

20

how are biofuels obtained

manufactured from from living things or from waste

21

how is tidal/wave energy produced

The movement of seawater in and out of a cavity on the shore compresses trapped air, driving a turbine.

22

how is geothermal energy obtained

Cold water is pumped under ground (in a hot volcanic region) and comes out as steam. Steam can be used for heating or to power turbines creating electricity.

23

how is wind obtained

wind turbines capture the wind, which makes the rotors spin and the movement of the blades drives a generator that creates energy.

24

economic advantage of nuclear power

increase in curent electricity generation capacity

25

economic disadvantage of nuclaer power

high costs to start up and begin

26

social advantage of nuclear power

employment opportunitites

27

social disadvantage of nuclear power

public fear of widespread radioactive contamination

28

political advantage of nuclear power

could be part owned with another country to futhur international relations

29

political disadvantage of nuclear power

potential terrorist target

30

envrionmental advantage of nuclear power

abundant and low carbon emissions
