Casa Verde: Texas Approves Wind Power Superhighway
According to an Associated Press article, Texas has preliminarily approved "a $4.9 billion plan to build new transmission lines to carry wind-generated electricity from gusty West Texas to urban areas like Dallas," and "build a slew of new turbines."

Casa Verde: Energy Saving Programs
A few days ago, I received an unusual thank you note in my mailbox and thought I'd tell you about it.
