We've all heard about the promise of green technology in regards to carbon emissions, the ozone layer and polar bears up on the ice cap. But, it could also save your portfolio.

One of the worst mistakes you can make right now is to withdraw money from your 401(k). Not only will you lock in the stock losses, but you'll pay a 10 percent penalty plus income tax on the money you take out.

If you are younger than 59 1/2 and withdraw funds, you're looking at an additional 35 percent reduction.
