energy resource management 2 Flashcards
how is coal being developed ? 3
- South Wales coal valleys
- important world energy resource
- used all over world largest producer of electricity
- in 2014 there was a 4% rise in consumption but a 7% decline in production
what are the advantages of the production and development of coal ? 4
- large quantities of coal available to 70 countries world wide
- mining coal is relatively easy and cheap
- relatively easy to convert coal into energy by burning it
- should last for another 250 years
what are the disadvantages of the production and development of coal ? 7
- greenhouse gases are emitted when the coal is burnt
- mining for coal can be dangerous
- burning coal releases harmful gases into the atmosphere causing air pollution
- acid rain is produced
- expensive to develop mines
- waste heaps are left close to coal mines
- open-cast mining significant impacts on surrounding environment
where is oil being developed ?
the Athabasca tar sands, Canada
what are the positive impacts on people of the development of oil ?
extracting resources and other jobs are linked to production process providing 514000 employees across Canada
what are the negative impacts on people of the development of oil ?
- broken pipelines and leaks regularly cause spillages that are difficult to clean up
- the spillages expose people to harmful chemicals
what are the negative impacts on the environment of the development of oil ?
- refining of bitumen releases 5-15% more CO2 into the air
- increasing greenhouse gas emissions
how is natural gas (fracking) being developed ?
USA has largest shale deposits
what are the positive impacts on people of the development of gas ?
fracking has made fuel prices much cheaper in USA because energy does not need to be imported
what are the negative impacts on people of the development of gas ?
evidence to show that fracking has resulted in gas entering people’s homes
what are the positive impacts on the environment of the development of gas ?
producing and using natural gas releases approx 1/2 carbon emissions of coal
what are the negative impacts on the environment of the development of gas ?
chemicals used to release the shale gas may leak and contaminate water supplies
how is Uranium being developed ?
USA is leading nuclear energy producer
what are the positive impacts on people of the development of uranium ?
nuclear power plants when they are operational produce relatively cheap and reliable electricity
what are the negative impacts on people of the development of uranium ?
nuclear power plants are very dangerous and if become damaged there is potential for leaks of radioactive material into the atmosphere
what are the positive impacts on the environment of the development of uranium ?
nuclear power produces much less carbon dioxide than fossil fuels lower contribution to global warming
what are the negative impacts on the environment of the development of uranium ?
waste products of nuclear energy are highly radioactive and very difficult and expensive to manage safely
how is wind being developed ?
London Array off the coast of Ramsgate, Kent is the worlds larges offshore wind farm
what are the positive impacts on people of the development of wind ?
home owners can have their own wind turbine so will benefit directly from ‘free’ energy
what are the negative impacts on people of the development of wind ?
can be unsightly many people find them visually intrusive
what are the positive impacts on the environment of the development of wind ?
do not emit greenhouse gases once in use
what are the negative impacts on the environment of the development of wind ?
need a local wind speed of more than m per second to be viable
