Uh-Oh! Government Motors Buys Carbon Offsets!

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.

Even the spelling in the announcement is sissified. These are not even American tons!

Organic Rankine Cycle: The Evolution of Water

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.)
