Uh-Oh! Government Motors Buys Carbon Offsets!

February 1st, 2012 | by Susan Kraemer

In a move that almost seems calculated to enrage the Right with its Fox- and Rush-driven rage against the Volt, Chevy has announced it will voluntarily buy "8 million tonnes" worth of carbon offsets for $40 million to help it meet "voluntary emission reduction goals" within five years.

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.)
