For Haas and Ross, it seems like you have a good chance. I think in all your bschool apps, you're going to want to emphasize:
- your formal and informal leadership experiences at work
- your passion for the energy sector and why you want to stay in it post-mba
- why you're involved with the non-profit (ie make sure schools know that you didn't do it just to get into school!)
Since you have two years of WE and are relatively young by bschool standards, I think adcom might pay extra attention to the "why now" aspect of your essays. So I'd be sure to have a good reason for why school now, as opposed to, say, two years from now is key to your achieving your goals.
Sorry, I can't really speak to the indian schools!
good luck!
