As colleges and universities set up new majors and minors in green studies, students are filling them up fast, according to an article in USA Today.

Nationwide, more than 100 majors, minors or certificates were created this year in energy and sustainability-focused programs at colleges big and small, says the Association for the Advancement of Sustainability in Higher Education. That's up from just three programs added in 2005.

Two factors are driving the surge: Students want the courses, and employers want the trained students, says Paul Rowland, the association's executive director.

"There's a great perception that there's a sweet spot with energy to do good and do well, and it appears to be the place of job growth," says Rob Melnick, executive dean of the Global Institute of Sustainability at Arizona State University, USA Today reported.
 
Arizona State's program has more than 600 students who have declared sustainability a major. Illinois State University has 65 majors in renewable energy, the report says. MIT and the University of California–Berkeley, among many others, have also seen more students drawn to sustainability programs.
