I recently watched a very interesting documentary about the perilous state of our planet, and things we can do to affect the course of necessary change. Narrated by Leonardo Dicaprio I highly recommend seeing this film,  The 11th Hour 

Creating fields of renewable energy themselves, a herd of cattle leisurely does what cows do best on a warm summer day, twenty five miles west of Amarillo, just outside Adrian, Texas at the Wildorado Wind Ranch where there are 70 wind turbine generators spanning the horizon. Each turbine measures 450 ft. from ground to the tip of one of three blades. Wind will generate power to parts of eight southern States: Texas, New Mexico, Oklahoma, Colorado, Kansas, Oklahoma, Arkansas and Louisiana.
