Solar hot water would be such a natural energy saving method in Yucatan. So would wind farms in the shallow coastline waters. The regular daily and night sea- and land-breezes are perfect.

Brenda,
there actually is a system like that on the market.
It consits of copper piping placed in the sun on the roof. Water cycles through the piping gets heated (copper is an excellent conductor for heat) and is collected in a insulated storage tank.
It’s not th sophisticated solar energy with solar panels but it works fairly good. I’m running my house on that system and I (almost) always have at least lukewarm water. Even in the morning after cold night like the past ones.
The system is pretty cheap too. As far as I remember I paid about 12000 pesos for it.

That much by 2012 sounds daunting. When I read an article written by the working gringa on the tenacas? or rooftop water cisterns becoming quite hot if they are not sheltered, I wondered if one could not utilize passive solar heating of the water by having two of them, one which would be open to heating by the sun, and route that through the hotwater heater, which would decrease the heating required, at least during the day, and another sheltered one for general use.

25% renewable energy by 2012 would be an amazing accomplishment.
It should get a lot easier as PV technology increases and the prices decrease. Good Luck!
