Looks like about half the ones I saw are in Christchurch, which is better than none but still not ideal. There don't look like there are very many overall there. I wonder where they go - Melbourne perhaps.
For reference, California is a little larger than all of New Zealand. I doubt there's that much total roof area in the entire United States. It would be an unprecedented feat of engineering.
There's a lot, though, and that's just the roofs: more could be built elsewhere, and if there's a commitment to it solar tech is likely to get much better very quickly.
On the other hand, unless Al Gore's optimism turns out to be justified, we're probably in for a century of unprecedented feats of engineering.
Al Gore isn't at all optimistic: he pulls no punches as to just how bad things are. What he does say is that there are still things the individual can do to make things better, both on a single-person and on a lobbying level. That's where the hope of his message comes in.
