I have no idea that because I own some stock in CPOW, I will soon be driving a canola powered car.
There are many sources of biodiesel and oil.
Petroleum is not going away anytime soon either.
The world's population is expanding. Huge populations have a new and burgeoning middle class. That means more cars, more energy demand.
There is plenty of money to go around in energy - solar, wind, biofuels, nuclear, oil, natural gas, etc. Energy is such a multi-billion dollar industry the numbers are staggering.
There are hundreds of new companies out there making big money helping to supply the world with energy. Not all of them are public. Here's an example of a non-public one.
Good to CPOW for dipping their toe in the pool. It will pay off.
