The world needs a new source of energy, an unspillable source.

if we implement alternative fuel, what will the fate of the Middle East be?

if we somehow develop alternative fuel sources (electric cars,hydrogen power, ect.) that completey replaces the need for fossil fuels, what will likely happen to the middle east?
oil is their biggest, most profitable resource, right?
They basically have not much else of an economy,
they are already thirld-world countries and that is with oil.

Wouldn’t the middle east completely implode with extreme poverty and religous fanaticism tearing the entire region apart with war and strife?
