There ARE alternatives to Gasoline, there are several in fact, however the biggest problem is not about finding an alternative, but incorporating it. Consider it, cars would have to be capable to run these other fuel sources, so thats over 500million transformations, and gas stations need to be able to sell this fuel source...so gas stations also need to conform.

It's an expensive process for the government, and the world, but it's doable.

There may be corruption in the oil world--i wouldn't be surprised if that were true. The owners of opec have a lot of power, and swipping a couple smart people off of the planet to keep their black gold safe is not a big deal for them. The whole oil industry is defiently corrupted, that's why i hope that someone finds an alternative soon...but not an electric alternative.
