When I took The Fundamentals of Energy, Environment and Sustainabilty at the University of Alberta in 2010, petroleum geologist professor Murray Gingras handled the geological side of the multi-disciplinary course.
He was one of the better teachers I've ever had, able to present his material in a way that was interesting, fascinating and somehow stuck in your mind!
Murray has been writing an oil and gas blog
that's covering some important aspects of Alberta's oil and gas, i.e. the pros and cons of fracking and other social issues surrounding oil and gas extraction.
He's good, because A) he knows his stuff inside out, B) he's not writing from any pre-determined ideological viewpoint and C) he writes clearly, in a style most of us can read.
Good bookmark for anybody who follows the sociological issues around Alberta's #1 industry and the source of most of our wealth.
