Q

Fossil fuels:

Disadvantages

A

Pollutes - releases lots of carbon dioxide
Using it too sparsely
Non renewable
When burnt carbon dioxide is released = global warming
Can cause acid rain

16
Q

Advantages hydroelectric

A

Creates water reserves as wells

17
Q

Disadvantage hydroelectric

A

Natural habitat destroyed

Flooding in near by areas

18
Q

Biofuel advantage

A

Cheap
Always available
Won’t run out if replaced
Takes in CO2 and releases CO2 = carbon neutral - when burnt

19
Q

Disadvantage biofuel

A

CO2 causes greenhouse gases

Land could be used for more useful things e.g. Food

20
Q

How generates electricity solar

A

Convert sunlight into energy

21
Q

How generates electricity wind

A

Wind turns the turbine

22
Q

How generates electricity tidal

A

Movement of the tide coming in and out turns the turbine

23
Q

How generates electricity hydroelectric

A

Moment of falling water turns turbine

24
Q

How generates electricity biofuel

A

The heat water used to burn CO2 the steam turns the turbine
