All things being equal, if a potential employer paid for your time away from the office to volunteer for an earth-friendly cause or provided you with free compact fluorescent light bulbs and an energy audit of your home, or even a hybrid car, would you be more inclined to join them? Leading by example, renewable energy firms are developing "green" or environmentally friendly employee benefits that align the core values of a CEO and culture of their organization with the core values of each employee.

"I think now, more than ever before, acting in an environmentally responsible way is top-of-mind with our employees and potential employees. Our core business is about helping utilities and companies think differently about energy consumption, we want to attract employees who share these values." --David Samuels, Senior Vice President of Human Resources, EnerNOC
