A Closer Look at Watts and Joules, Power and Energy
This article makes a good point about the distinction between energy and power. We really don’t want energy (all the wind and sunshine around us represents energy), what we want is power.

GOES-PUERTO RICO WATER AND ENERGY BALANCE (GOES-PRWEB) IS NOW OPERATIONAL
GOES-PRWEB is finally operational. 
I would like to thank my student, Victor Reventos, who made it possible through his Python programming skills. Here is a link to the results:
http://academic.uprm.edu/hdc/GOES-PRWEB_RESULTS/
New results will be published daily. Historical results are available from January 1, 2010. A list of the available output is provided below.

ACKNOWLEDGEMENTS: This research received partial funding from the following sources: NOAA-CREST (grant NA06OAR4810162) and USDA Hatch Project (Hatch-402). Special thanks to Dr. John Mecikalski for providing the solar radiation data, and Alejandra Rojas for providing various GIS maps used in this research.

GOES-PRWEB TO BECOME OPERATIONAL
Dear Friends
Total estimated actual evapotranspiration for 2010 derived from the GOES-PRWEB algorithm.
I am sending out this “heads up” to let you know that within the next few days the GOES-Puerto Rico Water and Energy Balance (PRWEB) model will become operational. “Operational” means that the results will appear on the website everyday. The water and energy balance results, and all other environmental parameters will be published in “near real-time” (i.e., through yesterday’s date). In other words, if you visit the website on April 2, 2012, for example, the results will be current up through April 1, 2012. In addition, graphic results will be provided on a daily basis starting from January 1, 2010.
As always, feel free to respond to my posts with questions or comments.

Harnessing nature’s solar cells
MIT researcher Andreas Mershin has a vision that within a few years, people in remote villages in the developing world may be able to make their own solar panels, at low cost, using otherwise worthless agricultural waste as their raw material.
