Water Power: Out with the New, In with the Old

January 31st, 2012 | by Zachary Shahan

Below is the original version of an article I wrote for GE's ecomagination site (full disclosure: I am being paid for the ecomagination article,.. but not for any extra views I drive to it). Water power has been fairly invisible in recent years as wind and solar have stolen the spotlight, but I think we're going to see a lot more attention put on it soon (and have already begun seeing that in 2012).


Organic Rankine Cycle: The Evolution of Water

August 21st, 2011 | by Guest Contributor

Industry can’t exist without water. Producing anything involves heat. When you’re a manufacturing facility, you’re lucky to be pushing out exhaust heat at less than 400 degrees Fahrenheit. It costs water to make steel, water to make cement, even water to make solar PV panels and wind turbines. And then it costs water to continue to run things. For example, your average solar parabolic plant sucks up between 760 and 920 gallons for every megawatt hour produced. (Editor's Note: wind and solar PV use a ton less than other power generation options, though.)
