Most of the MBA programs in energy management are aimed at people who want to land managerial jobs in the bigger energy sectors like oil and gas. If that's what you're looking for, Aberdeen has a good program, as do many schools in Texas like McCombs.

But there aren't many specialized MBAs for a career in the alternative energy fields. A lot of Haas grads go into the renewable sector, but this is arguably because of the school's focus in innovation and its proximity to Silicon Valley, where a lot of the renewable energy startups are.

There's Warwick as well - its Global Energy MBA program has some focus on alternatives.
