Carol's Green Chip Index is an index of 26 alternative, renewable and or clean energy companies. The index is updated daily, the website does not express hi /lo stock prices nor trading volumes and the index metric is in US Dollars. Long term, the index should yield to a NEW metric that will model the concept of "sustainability," simular to modeling the concept of perfection which is expressed by the value of 1.0. The "sustainability" metric will revolutionize Wall Street's dependence on using such irrational numbers as p = 3.14159 or e = 2.71828.
