UK Energy Perspective and Energy Use

Question 1

What primary energy source is UK dominated by?

Answer 1

1. Oil 48%
2. Gas 30%
3. Coal 14 %

Than

4. Nuclear heat
5. Renewables

Question 2

What differ coal from gas and oil as primary energy resources?

Answer 2

Much of the coal is used for electricity generation which results in high energy
losses due to the conversion efficiencies. Low delivered energy

Question 3

Delivered energy by fuel?

Answer 3

1. Oil /1. Lost in conversion and delivery
2. Gas
3. Electricity
4. Coal
5. Renewables and heat

Question 4

Delivered energy by sector?

Answer 4

1. Transport
2. Domestic 30% (83% is used for heating space and water)
3. Industry 15 %
4. Services

Question 5

Delivered energy by end use?

Answer 5

1. Transport
2. Space and water heating
3. Heat > 100 C
4. Lights and aplliances
5. Machinery
6. Cooking

Question 6

How much have the energy use increased in transport sector in the last 40 years in the UK?

Answer 6

Doubled

Question 7

What are primarly responsible to have increased the energy use transport sector?

Answer 7

Increases in car and truck use combined with increase in air transport.

Question 8

Transport energy use in the UK is dominated by?

Answer 8

Road use -> oil use

Question 9

Electricty generation in the UK is dominated by?

Answer 9

Coal and gas

Than nuclear and bio mass lastley oil and renewable resources (small small fraction)

A large loss in conversion from the power station input to the electricty generated.

Question 10

What will happen with the coal plats and what will the consequenses be in the UK?

Answer 10

They are closing down due to age and the impact of pollution control making many coal plant uneconomic.

As the coal is a large part of the electricty generation this can lead to shortage in electrical supply during peak times.

Question 11

What is the situation now and what are happening with renewable energy in the UK?

Answer 11

Renewable energy is small now. Wind around 11 GW capacity but due to government policies it is rapidly growing (along with rest of Europe).

Question 12

Do Scotland and UK have different climate change bills?

Answer 12

Yes!

Question 13

What are the main points in the UKs climate change bill?

Answer 13

1. A largely decarbonised electricity generation sector by 2030, primarily using renewable sources for electricity generation with other electricity generation from fossil fuelled plants utilising carbon capture and storage .
2. A largely de-carbonised heat sector by 2050 with significant progress by 2030 through a combination of reduced demand and energy efficiency, together with a massive increase in the use of renewable or low carbon heating
3. Almost complete decarbonisation of road transport by 2050 with significant progress by 2030 through wholesale adoption of electric cars and vans and significant decarbonisation of rail by 2050

Question 14

The UK energy consumption of fossil fuels is approximately ?

Answer 14

90 %

Question 15

What is the total energy consumption in the UK per year and what is the consumption by primary fuel?

Answer 15

Total consumption 2017 was 192 MToe
Coal 5%
Gas 39%
Oil 36% 
Nuclear 11.5%
Bioenergy and waste 8.5%
