Hopefully the prices double again.
Short term pain it is, but consider that there has probably been more funding poured into the search for alternative energy in the last 3yrs then there has been for the last 20.
Another 2 to 5yrs of this and we will see better electric and hybrid cars, more efficient solar panels, better technology to harvest energy(biofuels) from algae and other non-food fauna etc etc.
As is, a few dusty countries in the middle east and a few oil corporations have us all by the balls.
I look forward to the day when those countries no longer hold so much relevance to us and I don't have to see some crap about the middle east every time I turn on BBC news.
