World Of Difference In college, you've got the whole green business world in your hands.

Unless you've been living on Mars, you know that many consumers are going green and that businesses are rising to the challenge of providing environmentally sound products and services. Nowhere is that more evident than on college campuses, where student entrepreneurs are developing cutting-edge environmental ideas.

One example is the student-run Babson Environmental and Energy Club at Babson College. Comprised primarily of MBA students, the organization promotes entrepreneurship and career opportunities in the green sector. The club is even bringing clean-tech ideas--such as a residential-scale wind turbine to generate power--directly to the campus. "That's been one of our most exciting accomplishments," says Clinton White, co-president of the BEEC and a recent MBA graduate. "We know this is the future of energy and what companies are doing now: providing innovation to the space and looking at new solutions to address these larger global problems."

Also addressing global problems are recent Harvard University graduates Angela K. Antony and Sandra Ekong, both 22. In July 2007, they started The Beanstockd Project, a social media company that combines pop culture news and gossip with valuable environmental tips. "The Beanstockd blog uses popular culture as a vehicle to deliver environmental information to people who normally wouldn't be exposed to it," says Ekong. Things like posts detailing the latest updates on TV's Gossip Girl with a tie-in to the low-carbon dieting trend (eating foods that minimize your carbon footprint) are one way the company relays its earth-friendly message. Next month, the company will launch The Beanstockd Game, an alternate reality game that rewards users for making small green changes.
