Set forth below is a list of consulting, engineering & software firms active in clean energy and energy efficiency.  Better yet, they hire recent college graduates (and interns)!

This is a diversified list: small & large, pure-play & divisional focus, multiple RE sectors.  Some emphasize fossil-energy but are included because their roles open doors in Renewable Energy.  Engineers could get into most of them, but many do not require an engineering degree.  NGOs, VC/Pes and Incubators will be listed later.

Firms like these tend to rotate you through different projects and clients, enabling you to “try out” different things (industries, technologies, etc.) early o­n, which in turn is nice if you’re not sure of exactly what you want to do upon graduation.
