why are you so tough on corporate interests when the corporations are Big Agra, but not when they are Big Power??  
after all, you are giving cover to wilderness-destroying utilities by supporting the despicable and unsustainable model of new remote generation and transmission of "renewables" (snort!) even though the wind and solar farms will completely obliterate hundreds of thousands of acres of fragile wilderness.  not because URBAN DECENTRALIZED generation isn't entirely possible, but rather because it won't increase the profits and chokeholds of Big Power.

Hmmmm.  perhaps the Sierra club should give some thought to the purpose of wilderness, which is to provide crucial habitat for billions of species and which plays an extremely important role in the ecological balance of the planet, not to provide a cheapie power outlet to gluttonous McMansions and the Utilities that love them.

Sorry, no moral high ground until you rescind your endorsement of destruction of ecosystems (via dynamite, bulldozers, concrete, etc.) in pursuit of the dubious goal of preventing the destruction of ecosystems (via global warming).  eliminate the middleman and support local PV generation like San Francisco and Berkeley are finally doing.  stop selling out our wilderness!!!
