Pros
Everyone like a win win situation... SolarCity is a win, win, win, win, win, win and so on situation. I win my doing WELL for my family, my customers win becauase they keep money they would otherwise surrender to a monopoly, the monopoly wins because we are helping them achieve a mandate for clean electricity with letting investment on their part AND we reduce stress on the aging grid AND we impose competitive pressure on them so, eventually the monopoly will no longer be a monopoly and will actually have to WORK to keep customers. The local community wins because we create and retain great paying jobs in the community at the same time as freeing our customer's budget to have more money to invest in local businesses. Local non profits win because of partnerships we create that put money in their coffers. And the EARTH wins because we are using the only unexhaustible completely non polluting source of energy thus reducing our dependance on finite and polluting sources of energy.
Cons
When you work for a cause you get caught up in it. Free time gets very limited so learn to make the most of it.
