Component 2 : Consuming Energy Resources

Question 1

What are the three types of energy resources?

Answer 1

The three types of energy resources include renewable, non-renewable and recyclable

Question 2

What factors affect the distribution of energy?

Answer 2

Factors that affect the distribution of energy include climate, development, geology

Question 3

How does geology affect the distribution of energy?

Answer 3

Countries that live close to plate boundaries or oil reserves have higher access to energy. Living on plate boundaries increase geothermal energy

Question 4

How does climate affect the distribution of energy?

Answer 4

Climate affects the distribution of energy as for example, in sunnier areas they have more access to solar energy whereas in areas of high rainfall there is more access to HEP

Question 5

How does the development of a country affect the distribution of energy?

Answer 5

More developed countries have access to better, new technology

Question 6

What can the increased demand for oil lead to?

Answer 6

The increased demand for oil leads to increased extraction. If oil is in higher supply, it will cost less.

Question 7

Why may prices of oil increase?

Answer 7

Prices of oil can increase when there is a shortage in supply or where there are disruption in supply such as oil spills

Question 8

How does traditional fuel sources cause variation in energy use?

Answer 8

Traditional fuel sources can be biomass fuels that are used in rural areas of developing countries

Question 9

What is energy effeciency?

Answer 9

Energy effeciency is when you are being provided with the same service but using less energy

Question 10

What is energy conservation?

Answer 10

Energy conservation is not using as much energy

Question 11

Name ways of which homes can increase energy effeciency

Answer 11

Homes can increase energy effeciency with:

• double glazing
• solar panels
• loft insulation
• energy monitors
• energy efficient supplies

Question 12

How has London contributed to energy-efficient transport?

Answer 12

London has introduced congestion charges, saving 19% in traffic-related CO2 emissions

Question 13

How has Paris contributed to energy-efficient transport?

Answer 13

Paris introduced the cycling scheme, which resulted in thousands of tonnes of CO2 being reduce

Question 14

What are the positives of using wind turbines as a renewable energy resource?

Answer 14

The positives of using wind turbines as a renewable energy resource include less pollution and offshore can generate lots of energy

Question 15

What are the negatives of using wind turbines as a renewable energy resource?

Answer 15

The negatives of using wind turbines as a renewable energy resource include that it is unattractive and that it increases bird deaths

Question 16

What are the positives of hydroelectric power?

Answer 16

Hydroelectric power is reliable and constant, and HEP plants can also build dams for reduced flooding

Question 17

What are the negatives of hydroelectric power?

Answer 17

The negatives of HEP are that they are expensive to build and can change river flow which can impact wildlife

Question 18

What are the positives of biofuels?

Answer 18

Biofuels produce fewer carbon emissions when burned and it recycles crops and organic matter which leads to less waste and landfill

Question 19

What are the negatives of biofuels?

Answer 19

Biofuels require a lot of water and it can also increase deforestation as demand increases

Question 20

What are the reasons for increased renewable energy?

Answer 20

Renewable energy has increased as there has been rising affluence leading to environmental concerns and education, which means there is a greater awareness of climate and more people support the need for cleaner energy

Question 21

How can individuals reduce their energy consumption?

Answer 21

Individuals can reduce energy by calculating their carbon footprint and increasing their energy efficiency or conservation

Question 22

How has organisations affected the use of energy?

Answer 22

Some organisation has increased their use of sustainable practices however some companies still prefer cheaper nonrenewable energy

Question 23

How has governments affected the use of energy?

Answer 23

Governments have a choice between sustainable living and cheap energy for economic growth, especially in developing areas eg India
