I’m really interested in investing a portion of my portfolio into areas such as sustainable green energy or robotics. I feel we are slowly moving in that direction and I’m investing now (23) for the long hall (30-40 years) so it seems a good time to get into it. I’ve been looking into funds such as Jupiter ecology, Guinness sustainable energy and black rock next generation technology. I was wondering what other people think of this and whether you have any suggestions for funds to look into or steer away from? I use HL currently and plan to stay there.
