This is a fun one for your product/service/experience development team: come up with green innovations that are truly superior—not just eco-friendlier, but better-looking and cheaper than incumbent offerings. Like:

• Luna Road produces and installs a range of LED based road lighting with the aim of replacing traditional reflective “cat’s eyes”. Luna Road lights don’t have to rely on a car’s headlamps for reflected illumination, which means they provide drivers with visibility for miles ahead. The solar-powered lights offer 12 hours of after-dark lane lighting from 8 hours of daylight charging
• Philips (who by the way claim that 25% of their total sales now comes from green products) has introduced an ecological lighting concept called the Light Blossom. The Light Blossom collects energy and monitors light emissions differently in its ‘day’ and ‘night’ modes: at night the LEDs beam light only when and where needed through proximity-sensing technology, and during the day the Light Blossom imitates a real flower with petals that open toward (and follow) the sun, storing solar energy. The Light Blossom can also function as a wind turbine.
