Take for example Pacific Gas and Electric which got C for general happiness and a C for commitment to green technologies.  Should be more like F/B.

The utility is killing people, for heaven’s sakes. It scrimped on gas line inspection, upgrade and safety measures resulting in an explosion and fire that wiped out a neighborhood and killed eight people in 2010: http://en.wikipedia.org/wiki/2010_San_Bruno_pipeline_explosion. There have been other explosions since then including one in Cupertino. Pure negligence. If that isn’t an F, what is?

On the other hand PG&E has had solar incentives for many years resulting in one of the biggest uptakes of residential solar and now utility scale solar in the country. It took a boot in the rear from the Public Utilities Commission to do this, so just a B.
