I'm looking for an eco-friendly no-load mutual fund with no or low (under $500) minimum investment. I am so sick of investing in Chevron and Merck.

Yea, I don't blame you for not wanting to invest in oil companies!I know there are a few green mutual funds out there, but when I researched them a few years ago, they all had expense ratios around 2%, which is crazy high! I have started to put some money in an alternative energy ETF, the Market Vectors Global Alt. Energy Fund, ticket GEX. There's a couple of other alternative energy ETFs out there too: QCLN, PZD, PUW, and PBW. There's also a good water infrastructure ETF: PHO.good luck.
