Do you like to shop and be green? Well, now you can do both by joining Carrotmob KC at World of Spirits (1722 W. 39^th St.) on Oct. 21. Recently, Carrotmob KC went to 15 different Midtown area businesses in Kansas City. They asked them to commit a percentage of revenue towards making their business more energy efficient if the team brought a mob of paying customers. And World of Spirits won with the highest bid. That means that 24 percent of the revenue collected between 5-10 p.m. on Oct. 21 will go towards making this business greener.

Carrotmob originally started in San Francisco as a plan to make sustainability profitable for businesses through contests. Now, it has moved to a new level with the company Vigrance, which plans on creating a social network to create thousands of Carrotmob-type contests around the world.

So be a part of the carrot madness! Start on Oct. 21 by stocking up on beverages for the year — or even the decade — and help World of Spirits become greener. Or start a Carrotmob in your city! Check out the video below to get an idea on how.

San Francisco is paying its way to become a more energy efficient place by helping its citizens afford solar panels. The city’s board of supervisors recently approved the Solar Energy Incentive Program, GoSolarSF, which is now the country’s largest municipal solar program. With an annual budget of $3 million for the next 10 years, the program offers up to $6,000 to residents and up to $10,000 for businesses in the form of tax incentives for private solar installations. It will give out even more than that to low-income San Franciscans and nonprofit, multi-family residences. The program’s goal is to eventually have 10,000 solar rooftops in the city compared to the 770 they have right now. The program started accepting applications on July 1, 2008. Once they begin building, other cities will hopefully start to spend a little also.
