Yes, Of Course. Any nation has a role in this world even Liechtenstein with 35,365 ppl can make a change, what about Arabic countries that contains more than 350 millions of ppl?!
I’ll give you just few examples in 2 minutes,
I think that it would be better if you say : " provide the world by petrol and gaz " , I'll tell you something , the Next generations of energies are the renewable ones , and the Solar one is the 3rd most important renewable source with 105 GW.
Look at this picture:
http://en.wikipedia.org/wiki/Image:Solar_land_area.png
Solar power systems covering the areas defined by the dark disks could provide more than the world's total primary energy demand in 2006 (assuming a conversion efficiency of 8%). That is, all energy currently consumed, including heat, electricity, fossil fuels, etc., would be produced in the form of electricity by solar cells. The colors in the map show the local solar irradiance averaged over three years from 1991 to 1993 (24 hours a day) taking into account the cloud coverage available from weather satellites.
2 Of the 6 dark disks are in Arabic work:
-The most important is in Africa, Sahara exactly in ALGERIA (My region exactly ;-) ) and the other one is in the Arabic Gulf . Also it has a big reserve of underground water.
-Morocco and Tunisia have one of most important Phosphate reserves.
-knowing that the Arab world has Coasts on : Mediterranean Sea, Atlantic Ocean , Arabian Sea, Horn of Africa, Red sea , Suez Canal , Bab-el-Mandeb ,.....
-It has all the necessary to build up a strong nation, but unfortunately it lacks the wise management.So ,when the good managers come, it will be revolution believe me.
Finally , I think that next years the struggle will be for 3 things : Water reserves and sources ,energy sources ,Food and all this factors are widely available in Arab world .We deduce that the Arab world will play a major role next years , and will be a Big piece in the world's puzzle ;-)
Peace Out,
