"When you come to a fork in the road, take it." --Yogi BerraNEW YORK ( TheStreet) -- Ford's ( F) earnings report suggested that at least one American carmaker's going to prosper during the coming years. Considering where Ford was barely five years ago (as Jim Cramer noted), that's no small accomplishment. But where should investors go from here? That all depends on which industry scenario you think will unfold. There are a few different ones. Scenario 1 (status quo): Let's assume nothing much changes for the industry in the next few years. In that case, Ford seems a pretty good bet. At least based on the U.S. market. But the big enchilada is fast-growing China, and the 8,000-pound gorilla there is General Motors. With a growing middle class and the inevitability of China allowing domestic consumption to expand, China is hard not to think about. There are also Korean auto companies Kia and Hyundai. It's hard not to notice their increasing presence on America's highways. So pick which market you want to invest in. (There's also the integrated oil companies and refiners to pick from.) Scenario 2 (disruptive electricity). No, I'm not thinking of Tesla ( TSLA). Tesla's the conventional electric-car company. For the disruptive scenario, you should look at Start-Up Nation: The Story of Israel's Economic Miracle by Dan Senor and Saul Singer. Among the first persons discussed in this short (under 200 well-written pages) book is a young Israeli entrepreneur, Shai Agassi, whose company, Better Place, seeks to disrupt the electric-car marketplace with a change in paradigm. Agassi astutely recognized the challenges in having a plug-in electric car -- the time needed to recharge a battery. His alternative: At a service station, just change the decharged battery with one fully charged. If it takes less time than it does to fill up a gas tank, consumers would go for it. Is it economically feasible? Pilot studies in Israel, Denmark and Hawaii (finished by the end of the year) will determine if it may be. If they're successful, roll-out starts in 2012. Who wins then? Anyone involved in electricity generation and transportation. Think USEC ( USU), Quanta Power Services ( PWR), Comverge ( COMV), EnerNOC ( ENOC), Fluor ( FLR), Jacobs Engineering ( JEC), Mitsubishi, United Technologies ( UTX), Shaw Group ( SHAW), Areva, Siemens ( SI), Pike Electric ( PIKE), General Electric ( GE), ABB ( ABB) and Powell Industries ( POWL). There are lots of choices to pick from.
