Yeah, think about this for a second.
Oil companies are enormously profitable. Especially with the US's move toward more cooperation with bigger corporations, these corporations have a lot of influence in world governments. Advances to move toward another form of energy would not be supported by these oil companies. These companies obviously want to keep oil as the major form of energy. I think it must be considered that advancements in other renewable energy resources will likley be suppressed because of the money factor whether a government wants to move into a renewagle energy source or not.
I mean, if you take this example, highschool students made a car that runs on soy and gets 50MPG and goes 0-60 in 4 seconds. High school kids did this. You would think that big companies would be able to do this easily if kids can.

In my mind, same thing goes for healthcare. Companies are more involved in making pills and such to treat diseases and viruses than preventing them from happening. This is the money factor again. These's more money in prescribing someone a drug than keeping people healthy.
