Hey
don't feel too bad, i don't think anyone feels that confident for geography, there is just ridiculous amounts to remember, especially if you're revising all 6 topics in the beginning like me, although i am focusing on energy, superpowers and probably development as they link nicely together.
For energy i'd say your case studies want to focus on the global supply and demand for energy, The one about Russia supplying most of Europe is actually quite interesting, the power of how it can cut off the gas to any country it likes through the giant pipelines! (as it did to the Ukraine in i can't remember what year) (This case study is also good for superpowers, see how they link?)
It's also interesting Russia has decided to build a brand new pipeline straight to Germany, which by-passes the other poorer eastern european countries. This is thought to be because Germany at the moment, has the strongest economy in europe. Russia is cleverly increasing its international relations buy supplying them, but cleverly will cut out countries like Estonia, and Latvia who offer no benefit to Russia. (Other than having some sort of legacy through the break down of the soviet union) You could also look at the demand for oil, what happened in the Iran-iraq war, 1980-1988, and stuff like the oil crisis, peak oil, etc. Corruption also occurs in LEDC's that can't control who takes the oil or are in constant conflict over it. Countries like this include Nigeria who have a natural abundant supply of oil but have corroded pipes and a corrupt government in charge of distribution. You often have conflict between indigenous tribes who claim leaked oil in the river is theres, and they should be recieving profit from the state. Interestingly, the mangrove swamps absorb this oil and re-secrete it every year, killing themselves (ecocide) not really relevant, just interesting. Other corrupt oil rich countries include the smaller eastern european and eurasian countries like Azerbaijan, terrible for their corruption, but Baku the capital city looks like a lovely place. Anyway, The 10 marker though rarely asks for case studies, you can drop in a few for a few extra marks, it mainly wants you to focus on explaining the reasoning behind the figure it gives you, unless it states "Using specific examples" Which the 15 mark usually focuses on
I personally think a question about the future of energy may come up for the 15 marker, that's the one where you have to give a lot of specific examples. For this you could examine how it's becoming increasingly dangerous to transport Oil and Gas (explosive and targeted by terrorists) So countries are turning to LNG (liquified natural gas) which is safer and can be transferred over much longer distances, as far as Australia to Poland! This means that the energy players lose a bit of power which they won't be happy about !
Future energy security will decline in a business as usual approach, and we will tend to turn to coal more as reserves run dry, and cause major environmental degradation - Look at what's happening in Canada with the extraction of Oil Shale and Oil sands. The next future is to have a rich energy mix, so not being so reliant on one type of import from one country. England in particular is looking a wind power, a new farm is being built off the south east cost, (There is also a really big one in denmark or something too?) They are good, but unsightly to some people, make loud noises and are a danger to birds. It's also thought they interfere with the Ministry Of Defences satellite signals, which isn't good! Biodiversity of fish species actually increases around them though, as no bird prey or fishermen go near them! Energy can also come from nuclear energy, This is thought to be 'clean' as no net emissions are actually produced in the process (uranium through nuclear fission produces steam that turns turbines for energy) however, CO2 is obviously produced in the extraction of it. France is currently the country that uses the most nuclear power. It's dangers thought are obvious, the incidental radiation poisoning and birth defects from Chernobyl and more recently, the 2011 Fukushima power plant in Japan means it lacks public trust. Coal is also thought to provide up to 55% of energy in the future as it is more of abundant supply. There are obviously costs and benefits for other types of energy as well Hydroelectric power, Solar energy, Wave Energy, you know blah blah blah. The third type of energy is energy conservation which is obviously, if we use less, there's less CO2 less demand for energy, everyone is happy! (but with countries like China, this is not going to be achieved.)
Anyway i hope some of these case studies help you, Most all of them can be found in the big green A2 Book they're highlighted in there, just look at them and try to remember numbers and percentages for some - That's my downfall!
Also, try writing out a comment like this, I was pleasently surprised with how much i remembered! i last looked at energy on friday.
I personally think the technological fix is a very wishy-washy unit the case studies are poo and it's hard to define things and pick up marks, you may want to focus on superpowers or development that have clear, easy to remember case studies and theories you can apply to (They make you look 10x better!)
Hope this helps you get revising and good luck everyone!!!
