1

What are the three energy resources?

non renewable
renewable
recyclable

2

What is recyclable energy resources?

for example, biofuels and nuclear power

3

What are the negatives of hydroelectric dams?

They flood all the land behind the dams

4

What are the negatives of recyclable energy resources like nuclear power and biofuels?

-nuclear waste cant be easily disposed of
-risk of accidents and nuclear meltdowns
-biofuels take up a lot of room to be grown where food could be grown instead
-deforestation occurs because biofuels are grown instead

5

Why does distribution of the amount of energy used per person vary?

-Some countries have a high amount of natural resources which can be used for energy. e.g. Iceland has access to geothermal energy, Saudi Arabia has access to high amounts of oil
- some countries are more developed than others and hence have more money, richer people tend to use more energy for technology and manufacturing.
-some countries people cant afford to have cars or gas cookers

6

Why is oil consumption rising?

-increasing population
-as countries get richer, people buy more things which require increasing amount of energy
-as new technology is developed e.g. iPhones, people want the latest one and the companies want you to buy the newest product
-increased manufacturing/consuming
-increased amount of people with cars

7

What are 3 examples of renewable energy?

-solar
-wave
-wind
-water
-HEP
-Geo power
-tidal

8

What are natural sources of carbon emissions?

-respiration
-decomposition
-volcanoes
-some combustion

9

What are the negative environmental impacts of Wind turbines and solar panels?

-non renewable energy used to make them
-wind turbines could affect marine life

10

What are the negative environmental impacts of open cast coal mining?

-destroys habitats
-scars landscape
-non renewable
-produces carbon emissions
-chemical leaks
-deforestation

11

What are the negative environmental impacts of drilling for oil at sea?

-oil leaks kills animals
-non renewable
-increases carbon emissions
-carbon emissions produced in shipping
-oil rigs are expenisive

12

What are the negative environmental impacts of HEP?

-floods land:
-destroys villages, crops, habitats and spreads disease
-deforestation
-changes fish habitats

13

How is coal formed in the UK?

Most of the coal was formed in the carboniferous period when giant tropical plants in swamps decomposed and over time, the pressure turned it into coal

14

What are the advantages of exploiting coal in the uk?

-lots of coal in the uk that can be sold or used for energy
- create lots of jobs
-boosts the economy
-income for the government
-less imported energy stores

15

What are the negative impacts of exploiting coal in the uk?

-very deep coal, expensive and energy consuming to mine
-non renewable so will run out
-carbon emissions
-damage the environment and wildlife

16

How can location/accessibility affect access and cost of energy?

-Energy stores like coal may be very deep down meaning its harder to mine
-expensive drilling techniques may be required, e.g. fracking (using high pressure water and harmful chemicals to extract the oil from the rock)
- Some areas may have stronger wind/more sunlight

17

What is fracking?

It is an oil extraction processes by which high pressure water and chemicals are fire into the rocks 'fracturing' and splitting the rock in the shale layer. Tis means the oil can pour out and pumped back up

18

What is the definition of an unconventional oil source?

-a source of oil which is hard to mine due to the location or environment. Usually using steam/water to extract like fracking.
