Question 1

What do non renewable and renewable energy sources both have in common

Answer 1

They are both used to generate electricity

Question 2

3 main fossil fuels

Answer 2

Coal, oil, gas

Question 3

What are 3 things fossil fuels do or will do

Answer 3

• all run out one day
• all harm the environment
• provide most of our energy

Question 4

7 renewable energy sources

Answer 4

• sun (solar)
• wind
• water waves
• hydro-electricity
• bio fuel
• tides
• geothermal

Question 5

3 things renewable energy sources do and will do

Answer 5

• never run out
• they do damage the environment but in a less harmful way
• dont provide as much energy as most are unreliablem

Question 6

1 obvious place in which fuel is used

Answer 6

Transport

Question 7

Transport - non renewable energy resources

Answer 7

Petrol, diesel created from oil. Coal used in steam trains

Question 8

Transport - renewable energy resources

Answer 8

Vehicles that run pure on bio-fuels or mix bio-fuels with petrol and diesel (hybrid)

Question 9

Heat - non renewable energy resources

Answer 9

Natural gas, coal burnt on a fire, electric heaters

Question 10

Heat - renewable energy resources

Answer 10

• geothermal heat pump
• solar water heaters

Question 11

How is wind energy generated

Answer 11

Lots of wind turbines exposed in places like moors or round coasts. Each turbine has a generator inside of it and the rotating blades produce electricity.

Question 12

Adv of wind turbines

Answer 12

No pollution, no permanent damage to the landscape, does produce electricity

Question 13

Disadv of wind turbines

Answer 13

Spoil the view, noisy, when the wind stops or wind is too strong, its impossible to increase supply when there is extra demands, initial costs are high, unreliable, little energy produced

Question 14

Solar cells

Answer 14

Generate electicity from sunlight.

Question 15

Disadv of solar

Answer 15

Only work in day, use energy to manufacture in first place, not effective in cloudy countries, can’t increase power output when there is extra demand, initial costs are high

Question 16

Adv of solar

Answer 16

No pollution, reliable source of energy

Question 17

Geothermal power

Answer 17

Energy collected from underground thermal energy stores. Possible in volcanic areas, hot rocks lie close to the surface.

Question 18

Adv of geothermal

Answer 18

Free, reliable and little damage to environment

Question 19

Disadv geothermal

Answer 19

Are not many suitable locations, and the costs are high

Question 20

Hydro-electric power

Answer 20

Uses falling water to generate electricity. Requires the flooding of a valley by building a dam. Water is allowed through turbines where electricity is generated,

Question 21

Disadv hydroelectric power

Answer 21

Big impact on environment due to flooding of the valley - rotting vegetation releasing methane and Co2. Also a possible loss of habitat for some species. And the reservoirs can look unsightly when dried.m

Question 22

Adv of hydro electric power

Answer 22

Immediate response to demand of electricity, no pollution, reliable except for drought which is rare in britain. No fuel costs and minimul running costs. And useful way to generate electricity on a small scale in remote areas

Question 23

Wave power

Answer 23

Small wave powered turbines connected to generatores which generate electricity.

Question 24

Adv of wave power

Answer 24

No pollution, no fuel costs and minimal running costs

Question 25

Disadv of wave power

Answer 25

Disturbing sea beds, habitats of sea creatures, spoil view, unreiable, high intial costs, never likely to provide energy on a large scale

Question 26

Tidal barrages

Answer 26

Produced by the gravitational pull of the sun and moon. Big dams built across river estuaries with turbines in them. Tides come in and fills these estuaries and the water is then allowed out throuh turbines at a controlled speed,

Question 27

Adv tidal barrages

Answer 27

No pollution, reliable, potential of generating high amounts of energy and low running costs

Question 28

Disadv tidal barrages

Answer 28

Preventing boat access, spoils view, altering habitats, initial costs are high

Question 29

Bio fuels

Answer 29

Made from plants and waste and can produce energy or run cars in the same way as fossil fuels. Carbon neutral

Question 30

Adv biofuels

Answer 30

Reliable

Question 31

Disadv of biofuels

Answer 31

Can’t respond to immediate energy demands, costs are very high

Question 32

3 reasons we burn fossil fuels

Answer 32

Oil to fuel cars, generate electicity, gas to heat homes and cook food

Question 33

Reasons against renewable energy sources

Answer 33

Price - costs are extremely high with low output and fossil fuel prices are very effective
Location of where to put these sources
Most are not reliable and could waste significants amounts of money
Personal changes are expensive (cars)

Question 34

What is natural gas used for?

Answer 34

To heat homes. The gas is used to heat water which is then pumped to radiators throughout the home

Question 35

Use of geothermal heat pump?

Answer 35

Uses geothermal energy resources to heat buildings

Question 36

How do solar water heaters work?

Answer 36

They work by using the sun to heat water which is then pumped into radiators in the buildings
