Just before the holidays, we put up a list of green heroes and green villains for 2008 and asked readers to vote for their favorite (or, um, unfavorite).

Readership is low around the holidays, so I just want to bring those lists to your attention one last time, because voting closes in 24 hours! At that point we will declare winners and start handing out prizes, as soon as we come up with some prizes.

Currently the top hero is Sierra Club’s anti-coal activist Bruce Nilles, with 661 votes — a healthy lead over the second place hero James Hansen at 437. (Guess it helps to have a very large club at your back.)

Third is Barack Obama with 399 and fourth is Michael Pollan with 258.

Dead last? Poor Jim Rogers, CEO of Duke Energy, with 6 votes.

Meanwhile, flaccid apparatchik Stephen Johnson, head of the EPA, is walking away with the top villain spot. He’s got 397 votes, far outpacing second place Sarah Palin (240) and third place (and personal favorite) Massey Energy CEO Don Blankenship (236).

Amusingly, Jim Rogers is losing this one too — just 12 votes. Perhaps we should come up with a new category for this dude.

Anyway: Go vote now while you still can! We’ll announce the final winners tomorrow.
