Sorry if this was already posted back when it was current, this is an interesting article:

A few point of note:
In 1897, 1/3 of the homes in Pasedena heated their water with solar units.
As late as 1941 there were 60,000 solar water heating units installed in Florida, and over half of the population of Miami used solar water heaters.
OK, so the population of Miami was about 37 in 1941, but still, it seems like we're moving backwards.
Maybe this ought to go under "rants and opinions". OK, I just changed the section to R&O, so I can be a little more inflamatory.
What the %#&%$^%% happened?!?!?!? Is electricity just to $*^&$%^$# cheap and convenient?!?!?
For what it's worth,
