Will 'green grads' have an upper hand over geology majors?

Current energy industry downturn have you a bit concerned about pursuing that engineering or geology degree? You could try an undergrad degree in solar energy, notes USAToday:

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.

Some of these new offerings really are about “energy” as a general policy topic, not necessarily just renewable energy. But unless you’re at a university community that has some foundation in the energy industry (as say Texas A&M, University of Texas or University of Houston) is one likely to get many offerings from those fields?
