This was a pretty hard poll. First, a lot of people feeling personally challenged, which wasn't the intention of the poll.
Second, a lot of discussion of what qualifies as "clean energy" or if that's even a worthwhile term.
For me, qualified yes. I'm in Quebec, which is almost entirely on hydroelectric power. That's low emissions, but some serious environmental impact.
I also burn wood for heat once or twice a week, which is renewable but not particularly clean.
