I just saw interesting stats on the news the other day.
Firstly they showed a graph about past oil spikes and how consumption dropped straight after. However with the current oil spike consumption has risin. I'm assuming that this means oil is not over-valued and the price can still move higher.
Second, it showed the rises in consumption on the G7 nations rose only 2%(I'm guessing over a year, I can't remember the time period..) Whilest China's consumption has risin by 17%.
This sounds really nerdy but I think it'll be interesting times to come with the price of energy.
