Yesterday a gang of Greenpeace “activists” descended on the San Francisco Apple store to demand that Apple use clean energy.

Some were dressed like members of a hipster, black-clad cleaning crew. Others plastered outsize decals on the minimalist retail establishment’s windows. And anyone taking an Apple device for a test drive Tuesday morning was automatically routed to a Greenpeace website.

The store takeover — carried out in sync with actions in New York and Toronto — was part of a global Greenpeace campaign to get technology giants to switch to renewable sources of energy for powering the electricity-hungry information cloud.

Unlike their OWS brothers-in-smarms, they were organized, and this is where it gets cute.

Protests like this take months of meticulous planning. And on Monday night, about 30 Bay Area activists gathered in a chilly Greenpeace warehouse in San Francisco’s industrial Dog Patch neighborhood to get their final marching orders.

Dinner was vegan and served on compostable paper plates. The cleanourcloud.com printed materials were recyclable, union-made and locally sourced. Transportation to the mid-morning action in the center of this traffic-clogged, construction-choked city would be by van pool.

Oh, how green thou art, my brother.
