Congratulations on wanting to make money.
First, I would ask you to consider your investing strategies and risk tolerance. Are you buying strength, buying low, what's your sell point, timeframe, etc.
Second, regardless of a green trend (or fad), you should still remain diversified.
Ethanol production and the futures market that increases the cost of food due to shortages of the food products being put towards ethanol are solid bets. Corn Futures, Ethanol Producers, those who will supply parts to the producers, those with distribution networks. So start researching.
Some are leaving it to experts that know the green market and are interested in profits. Meaning they buy green funds (e.g. Winslow Green Growth). There are many to choose from.
For the record I do not own Green funds or stocks at the present time.
