I am in most energy stocks - CVX (Chevron) BPT (Prudhole Bay), Exxon, etc. . .APU is just a nice stable company with a needed product, and a steady income/dividend stream. I have a lot of friends up in Napa and Sonoma who are too far out of town for gas lines - they are all customers, that is how I ran across APU a few years ago. . .lots of new houses in Calif (and elsewhere) that are off the grid.
