There are two “green” inaugural balls being hosted during Barack Obama’s big party next week.

Al Gore is hosting The Green Ball, which, according to the website, will celebrate “the expanding network of diverse organizations, companies, and individuals committed to advancing our clean economy to create shared prosperity for all.” It is invitation only.

Another organization is hosting The Green Inaugural Ball, which, according to organizers, will be wind-powered. All the food to be served will be organic and, to the extent possible, locally grown. You can go to this one — for $500 per person or more.

Neither event will be hosted by — or even attended by — the Obamas. But the concept does fit with Mr. Obama’s major policy theme.
