<prompt> Human: So I have a small amount of spare cash, about 1000. I want to invest it in ethical ways, preferably into renewable energy. Would the best way to do this just be buying stocks in renewable energy companies? Is there a better alternative? Or is this just too low of an amount to even bother with? Thanks.  <response>: Dont bother investing in single stocks - too much risk.Unless you are just doing it for fun I suppose.
