California has been working on increasing its use of renewable energy.  It had a goal of 33% renewable energy by 2020. This article talks about how California has already been working on doubling this goal.  One of the ideas that will help to reach this goal is to eventually create buildings and homes that have zero net energy.  Photovoltaic projects are the main source of this new renewable energy.  San Diego has more power from distributed energy, mainly from solar panels, than any other city in California.  There are almost 5000 solar installations in San Diego alone.  Then next energy project is trying to connect all of the rooftop solar panels to create one grid.  The good thing about all of these future projects, besides the use of renewable energy, is that it seems to be very cost efficient.  The good these projects will bring will be worth the money that is needed to design these projects.
