I got the latest energy brief from the Guinness Atkinson Global Energy fund. You can sign up to receive it via e-mail here.
If you're interested in investments in the energy sector, I highly recommend you sign up for the newsletter, it is very good and contains a nice overview of events in the energy markets, the fund manager's musings, and the portfolio's holdings.
There are not a lot of energy focused funds out there, so if you're interested in one, I'd take a look at this one.
There are others I like, but there are problems with them. Vanguard Energy is currently closed to new investors, and AIM Energy and Blackrock Global Resources both have loads.
