Glory
Let's break it down to simplest terms: energy brokers help businesses and municipalities save money. And when such entities are able to do so, the people who work and live in those places are a little more secure in their jobs and daily lives. Stockholders get a better return on their investments, productivity increases, and cost of living in that particular town or city stays relatively low. So yeah, that's pretty good.
There's also that whole "saving the Earth" thing, too. So, though your negotiation tactics may be somewhat, er, bullish, you'll still be doing some good in the world. And with new energy technology on the rise, you'll be able to do even more good if you keep at it.
