Energy Resources Flashcards
where are most nuclear power stations?
MEDCs
europe
USA
china
japan
good location for nuclear power plants
space, flat land near water supply near cities (workers, & send power) away from natural hazards local community accept it country's laws accept it government support good transport/communication workers, raw materials
case study
thermal energy
Ratcliffe-On-Soar in Nottinghamshire, England
(use fossil fuels)
close to Derbyshire & Nottinghamshire coal mines (supply of raw materials)
close to river Trent, water used for cooling
close to major pop. centres of Derby
Leicester & Nottingham - workers supply
outside of major cities
what is the problem with fossil fuels?
polluting gases are created when they burn - contributes to global warming + greenhouse effect
non-renewable - won’t last forever
dangerous to get out of earth
subsidence - ground collapse
dangerous to transport
hot water back into river - damages ecosystem
what is the greenhouse effect?
why is it good?
when is it bad?
greenhouse gases (CO2, methane, etc) that trap heat from the sun inside the earth
without it the earth would be too cold, about -30°C
it is only bad when there is enhanced greenhouse effect, when there is too much of the gases and too much heat gets trapped & earth gets too warm
what is water scarcity?
when the demand for water is higher than the supply available
what are the 2 types of water scarcity?
physical - not enough water, arid, dry
economic - no money to get water & store it
what is most of the world’s water used for?
agriculture (75%)
what are the effects of contaminated water?
cholera
diarrhoea
children lose school days due to water related illnesses
girls lose school days in search for water
contaminated rivers damage ecosystem
every minute 1 person in india dies from water-related illnesses
case study
oil
foreign companies use nigeria’s oil
advantages: cheap for who buys it nigeria earns money, helps economy new jobs good location - easy transportation
disadvantages: pollution acid rain oil spills shore erosion fish migrated to deeper waters - fishermen lost jobs
describe the social & environmental impacts of the collection & burning of fuelwood
increased demand for wood due to population growth
deforestation - landslides, animal habitat loss, climate changes
health issues due to gases produced
dangerous - may burn houses down
school days lost to get the wood
dangerous place for children to go to get wood
free - don’t pay for it, however there’s a lack of funds for alternatives
what are solutions to fuelwood?
better type of stove that uses less wood & transports smoke away
educate people about problems of using it
make other cheap alternatives available
