Food, Water and Energy Resources Flashcards
What is a HIC?
A high-income economy is defined by the World Bank as a country with a gross national income per capita of US$12,056 or more in 2017, calculated using the Atlas method.[1] While the term “high-income” is often used interchangeably with “First World” and “developed country”
What examples of Energy use can you think of in a HIC?
Transport: Planes, Cars, Trains, Buses
Modern Technology: Mobile phones, games consoles, oven
Services: Hospitals, schools, Police
Leisure: Xbox, Concerts, football matches
Manufacturing: Cement, Car making, Steel production
Where does the UK get its energy from?
Nuclear
Fossil Fuels
Renewables
What are advantages of fossil fuels?
They generate large amounts of energy quite cheaply.
As technology improves, more reserves can be accessed.
Locating where fossil fuels are is quite easy.
Oil and gas can be transported through pipelines.
The means for extracting fossil fuels is already in existence.
What are disadvantages of fossil fuels?
They release carbon dioxide when they are burnt, creating pollution.
Carbon dioxide contributes to the greenhouse effect and global warming.
Mining can create ugly scars on the landscape.
Mining can be dangerous, especially as the most easily accessible deposits are used up.
Oil spills can cause environmental damage.
Supplies are running out and new sources are harder to get to. Oil and gas are both predicted to run out within 100 years.
Oil is mainly produced outside the UK, so prices are set by other countries.
Is Nuclear power renewable or non-renewable?
Non-renewable
How do we get Nuclear power?
Nuclear power is created from the release of energy from nuclear reactions. These reactions usually use uranium or plutonium. A relatively small amount of fuel is required to produce the energy. Most by-products of the reactions are radioactive. There is a debate about whether or not nuclear power should be used.
What are the advantages of Nuclear power?
Only small amounts of fuel needed to produce lots of energy compared to fossil fuels.
Low carbon emissions.
Tends to be supported by large companies and governments.
Once up and running it is cheap to produce electricity.
There has been a lot of investment in making sure it is as safe as possible.
What are the disadvantages of nuclear power?
Nuclear waste is highly radioactive.
Accidents and leaks can be deadly and last for a long time.
Storing nuclear waste is very expensive.
Decommissioning nuclear power stations is very expensive.
Uranium and plutonium are not renewable so will run out.
Give some examples of renewable energy
Hydro-Electric Wind Solar Biomas Geothermal Wave or tidal
Which energy source do you think we should be using in the UK? Support your argument
no right answers here but I would say that burning fossil fuels is NOT the answer because they are running out, we don’t have any so we have to buy them and they contribute to global warming.
Renewables are the way forward BUT the technology is still new and we cannot currently get enough energy from it and its not stable or consistent because you need wind for wind turbines..
I think that we need to invest in renewables BUT for now we also need nuclear as the advantage outweigh the negatives.
What is the Greenhouse effect?
The retention of heat in the atmosphere caused by the build-up of greenhouse gases which include CO2 and methane
Why is Antartica important?
It holds 90% of the worlds ice and if it melts then the sea will rise by 58-60 metres causing floods and destruction
What increases global warming?
Burning fossil fuels
Increased consumption of meat means cows and other animals produce more methane
What is food security?
The entire population has access to enough safe and nutritious food
