What fossil fuel was the vital energy supplier up to 1920 and list some of its disadvantages
Coal was the main fossil fuel. Its disadvantages are that it has an adverse effect on peoples health like giving the public asthma and also cancer. Smog can also be caused.
What fossil fuel had a rapid increase from 1950 and what plan played a art in this
Crude oil had a rapid increase because of the marshal plan which seen Europe have an increase in roads and cars
What are the four factors that increased fossil fuel usage
- Increase in world population - This increases demand using up more fossil fuels
- Increase in the number of goods and services - Consumers have had a growth in disposable income therefor companys offer more goods and services
- Increased travel - Increased availability of flights throughout the year
4- Capitalism- some argue that they just aim to maximise profits and don’t care about the environment
Name 4 emerging economies
India, Brazil, China and Russia
List 5 reasons demand will rise with these emerging economies
- Infrastructure - crude oil will be needed to make concrete and steal etc
- Technology- emerging economies will need plastics for the likes of telecomms
- Health care - Pharmaceuticals will be in demand which uses crude oil
- Energy - as the growth in population and new technology demand will rise for energy
- Lifestyle- as disposable income goes up more people will get phones and other cosmetics
What is the definition of fuel security
The uninterrupted availability of energy sources at an affordable price
What is uninterrupted availability
This means the energy should always be available when required.
What does a country need if they want strong fuel security
Strong foreign relations with the nations felling the fuel.
Safe transportation routes from nation to nation
How does affordable price play into fuel security
If the fuel is to expensive there is no benefit in having a good supply of fuel
How has fossil fuel reserves influenced geo politics
Nations with high fossil fuel reserves like iraq iran and other main fossil fuel suppling countries have been expoilted for years which leads to wars like the one in iran.
What are the two main causes for habitat degradation
- Deforestation - cutting down trees can kill animals who cant adapt to new habitats
- Rise in sea levels / temperature - this can cause polar ice caps to melt and polar bears losing habitats
What are the four effects burning fossil fuels has on the environment
- Land and water contamination
- Habitat degradation
- Impact on biodiversity
- Air quality reduction
explain the effects of land and water contamination
Land contamination- fossil fuel spillages on land contaminate the ground
water contamination- an oil tanker spilling can cause contamination
explain the effects of air quality from combusting fossil fuels
The combustion of fossil fuels puts harmful gas in the atmosphere which can cause acid rain
explain the effects on biodiversity fossil fuels have
when some animals lose their habitat they die off as the cannot adapt to a new one they lose their habitat because trees can get cut down due to accessing new oil reserves
