Why Blue Energy needs trading

Fossil fuel is traded as commodity in global market. Is there anything you can do with the energy you consume everyday?

While writing this webpage, ABC television aired Dick Smith's own documentary production - Ten Bucks a Liter. In this show, Mr. Smith made no discussion on engine efficiency. He failed to see the most important "attributes" that differentiate fossil energy and renewable energy. Without such in depth of understanding, the world could eventually face the reality that petrol price will be sold at (or more than) $10/L. It will happen if we don't address many important issues, such as, heat engine efficiency.
