Energy Flashcards
Reasons why developed countries use more energy
population
POPULATION
- more people consume more energy if they have wealth
- more people= more consumption
Reasons why developed countries use more energy
wealth
WEALTH
-if people have more money, then they can buy more appliances such as TVs/Laptops/ heat their homes, which all increase the amount of energy consumed
Reasons why developed countries use more energy
more access to technology
MORE ACCESS TO TECHNOLOGY
-now, farming uses more machinery and fertilisers, and people have more iPads/ lighting in their homes
Reasons why developed countries use more energy
larger industries
LARGER INDUSTRIES
-heavier industries consume more energy(steel), where as service industries use less(banking)
Reasons why developed countries use more energy
transport
TRANSPORT
-people in developed countries have higher car ownership rates, whereas in LEDC people walk/cycle to work
Reasons why energy use is slowly rising in developed countries
(people are switching to energy efficient)
energy prices are rising, so people are switching to energy efficient appliances such as lights and washing machines
- people are using smart meters to monitor their usage
- all helps to reduce energy usage
Reasons why energy use is slowly rising in developed countries
(population is steady/declining)
- no added demand for energy
- service industries require less energy(IT compared to steel)
Reasons why energy use is slowly rising in developed countries
(emissions are controlled)
- CO2 emissions are strictly monitored, to allow factories to be more efficient
- these laws reduce the energy usage
Reasons why energy use is slowly rising in developed countries
(good education)
- education about climate change is good so people can make the decision to use less energy and use more efficient boilers reduce energy usage
- government policy such as insulation and more efficient boilers reduce usage in the home
Reasons why energy use is rising in developing countries
wealth is rising
-people can buy more household appliances such as fridges which use more energy
Reasons why energy use is rising in developing countries
Geographical location
- people heat their homes when its cold or use air conditioning units when its hold which increases energy usage
- in CHINA in 1995 there were 8 air conditioning units for every 100 households, whereas in 2009 there were 106 units for every 100 households
Reasons why energy use is rising in developing countries
population is rising
-more people require street lighting and electricity in their homes, these require more power stations so more energy is used
Reasons why energy use is rising in developing countries
less education
- people are less aware of how energy use impacts the environment, and the government do not have the money to improve insulation in buildings
Reasons why energy use is rising in developing countries
car ownership is increasing
- in INDIA in 2003, there were 600,000 new cars bought, and in 2010, 2,300,000 cars were bought
- this increases the overall energy usage
Potential solar energy
- higher near the equator
- due to the light being concentrated
- in AFRICA< countries receive up to 325 days of sunlight a year
Wind energy potential
-countries that are in the central part have more potential for wind energy
Reasons why energy use is rising in developing countries:
People heat their homes
when its cold people heat their homes and when its hot they use air conditioning which uses gas/electricity
-In 2009 there were 106 air conditioning units for every 100 households
Reasons why energy use is rising in developing countries:
Have many heavy industries
steel= uses lots of energy and farming is becoming more mechanised and fertilisers are more widely used which results in the burning of fossil fuels
Renewable energy:
Nuclear case study (France)
-France contains 59 nuclear fission reactors which generate 78% of the countries electricity
Dissposure of nuclear waste
- underground lab at Bure= resting place for most of the highly radioactive waste
- half a km underground
Renewable energy: Wind power (Denmark)
- great potential in Denmark for wind power as its very flat and has a lot of wind
- they have invested heavily in wind power and have become world leaders in manufacturing wind turbines
KEY ISSUES
- the wind blows more consistently at night when energy needs are lowest, therefore they end up exporting it to Norway/Sweeden
- energy cannot be stored
- people object them because the way they look
Renewable energy: Coal mining (Australia)
australia has 9% of the worlds coal reserves
-75% of the countries electricity comes from coal fired power stations
Key issues
- distributes biodiversity over the barrier reef
- looking to open the worlds biggest coal mine which will damage the great barrier reef
Renewable energy: Tidal energy (Scotland)
-could produce 42% of Scotlands energy requirements
Key issues
- great potential, but would go through entire firth, so would disrupt marine life
- very expensive
Renewable energy:
HAP- Belomonte Dam (Brazil)
3rd largest dam in the world
provides a clean fuel source that will help reduce brazil’s CO2 emissions
more efficient, as technology has improved
Key issues
- between 12,000-20,000 people will be displaced
- disturbing wildlife/ migrating fish
Renewable energy: Oil pipelines (Alaska)
1 million barrels of oil carrie in the Trans Alaskan pipeline per day
Key issues
- crosses over rivers and streams, the pipe could leak into the river
- if oil gets into sea, it will affect marine life
Renewable energy:
Biofuel (Sierra leone)
Planting large area with sugar cane to produce bio-ethanol
Key issues
99% of population living here said that food production has gone down, due to international companies buying the land
less efficient than petrol
