Profile Eval: Will my work experience help or hurt?

Hi there,

I was wondering if you might be able to give me feedback / guidance on my profile. Also, I wanted to get your take on my experience, which I feel is unique to b-school applicants but am not sure if that is a good or bad thing. Finally, any schools that you may think I should focus more heavily on, or any I've missed, would be super helpful (I am not applying until next year).

Goal: Renewable Energy is my passion. Am interested in Renewable Energy marketing and entrepreneurship.

Age at matriculation: 24 (yes, I am a young applicant = another hurdle)

GMAT: 650 (V44, Q 35, AWA 6) - another hurdle....

GPA: 3.82 / 4.0 (overall and identical GPA in major) at American University, in Washington D.C. Major: Environmental Policy

Work Experience: 3 years at matriculation. Experience consists of 2 years in an exclusive (25 participants accepted nationwide), managerial (fast-track manager program), developmental (various trainings like 7 Habits throughout the 2 years) leadership program in the U.S. Environmental Protection Agency Headquarters in Washington, D.C. There, I worked directly for two Presidential Appointees, also worked with small businesses and communities in the Smart Growth arena, and also worked as the energy and environment Fellow for a U.S. Senator (worked directly with the Senator and his senior staff).

Extra curricular activities:
In college - Philanthropy chairman for Delta Tau Delta Fraternity - helped raise $1600 for Make a Wish Foundation, as well as landscaping events at a needy elementary through the Adopt a School Program. I also was a Freshman Service Experience leader, where I led a group of 20 incoming freshman to revitalize an inner-city park in Southeast D.C.
At work: Mentor to elementary students through a non-profit organization.

Schools I am looking into (and plan to apply R1)
Reach schools - Chicago Booth, Cornell Johnson, NYU Stern, Michigan Ross
In reach schools - Boston Univ, Ohio St Fisher, UMD Smith
Safe Schools - George Washington, Babson Olin, Case Western Weatherhead

Thanks so much!
