Alternative fuel vehicles: worth the trouble?

In Portland, we have the following fuel options:

1. Gasoline
2. Diesel (VW, Audi, BMW, full size trucks)
3. Biodiesel (any diesel converted to bio, for around $2k)
4. Electric (Leaf & Volt)

The bottom line, if money is your #1 priority, is that gasoline is your single best choice for now.  Electric is fast becoming an attractive offer because of our low energy costs (via hydroelectric).
