1
Q

name the three fossil fuels

A

coal, oil and gas

2
Q

what do we mean by the term non-renewable energy

A

a non-renewable energy source is one that will run out eg coal, oil and gas

3
Q

what do we mean by the term ‘renewable’ resources

A

a renewable resource energy source is one that will NOT run out.

4
Q

when and how were fossil fuels created?

A

they were created millions of years ago from the squashed remains of plants and animals

5
Q

how do we get electricity from fossil fuels

A

burn them to heat up water to form steamsteam turns a turbineturbine turns a generator which produces electricity

6
Q

name three advantages of fossil fuels

A

reliableeasily storedproduce lots of energy

7
Q

name three disadvantages of fossil fuels

A

burning fossil fuels causes pollutionfossil fuels WILL run out

8
Q

name as many renewable sources of power as you can

A

wind power wave power solar powerhydro electric power tidal power geothermal power

9
Q

name three advantages of renewable energy sources

A

they WON’T run outthe are freethey DO NOT harm the environment

10
Q

name three disadvantages of renewable energy sources

A

the equipment is expensivenot always availablesome can only be used in certain areas

11
Q

what do we mean by the term Geothermal power

A

Geo means from the earth and thermal means heatgeothermal is heat from under the earths surface

12
Q

name two advantages of Geothermal power

A

no pollutionno fuel neededfree energy once built

13
Q

name two disadvantages of geothermal power

A

not available in all areasunpredictableban bring harmful gases to the earths surface

14
Q

what do we mean by tidal power

A

energy harnessed from the incoming and outgoing tide

15
Q

how does tidal power produce electricity

A

water flows over a turbine, the turbine turns a generator and the generator produces electricity

16
Q

how do we get electricity from geothermal power

A

the heat in the earth boils water to make steam, the steam turns the turbine and the turbine turns a generator which produces electricity

17
Q

two advantages of tidal power

A

once built the energy is freeproduces no greenhouse gasestides are predictable

18
Q

name two disadvantages of tidal power

A

can affect wildlifenot many suitable sitesexpensive to build

19
Q

what are biofuels

A

fuels produced from natural sources like wood and sugar cane

20
Q

name two advantages of biofuels

A

it uses waste materialthe fuel is cheapless demand on fossil fuels

21
Q

name two advantages of wind power

A

free once turbine is builtland beneath turbine can be farmedNO POLLUTION

22
Q

name two disadvantages of wind power

A

not always reliable - not always windyturbines are expensivewind can be too strong for the turbinespeople think they spoil the view

23
Q

name two disadvantages of solar power

A

its not always sunny ( night time)not reliablesolar panels can be expensive

24
Q

what is wind power

A

wind energy captured by a wind turbine and turned into electricity

25
Q

what do we mean by solar power

A

capturing energy from the sun

26
Q

name two advantages of solar energy

A

free energy - once solar panels in placethe suns energy will not run outNO POLLUTION

27
Q

name two advantages of wave power

A

free energy once set upnot expensive to runcan produce lots of energy

28
Q

name two disadvantages of wave power

A

dependent on the seasome designs are noisyrough weather at sea

29
Q

name two disadvantages of nuclear power

A

produces toxic wastewaste is expensive to dispose ofexpensive to build and maintain safety

30
Q

what is wave power

A

wave power is captured energy from the waves

31
Q

how do we get energy from nuclear power

A

nuclear reaction produces heatheat boils watersteam from boiling water steam turns the turbine which then turns the generator

32
Q

name two disadvantages of biofuels

A

collecting or growing food takes timecan CAUSE POLLUTION
