The oil prices

My prediction then when the oil prices reached one hundred and fifty U.S. dollars that it was going to go higher and higher tell other sources of energy like wind and solar energy nearly cost the same as oil energy. But it didn't. Instead it went down and down. What were the causes that made the oil prices go up and then down so fast like this? It took the prices of oil to dabble about two years, and then after the west financial crises just less than six months for the prices of oil to drop down to the third and less. What happened to the world in the latest three years? The problem lies with consumers of oil first. We have seen the prices of food and oil rising fast but also we are now seeing them falling down faster, and all of this was caused mainly by consumers of oil ,the developed world, USA, China for example and its booming economy and other emerging economies was the causes of higher oil prices. And the third world has no effect on any thing at all, neither in oil prices nor in food prices, Saudi Arabia the largest oil producer and its King Abdullah could not do any thing then when the prices of oil was high although he knew that the high prices was not the result of the shortage of supplies
