Past, present, and potential future California adoption methodologies for renewable energy resources

I believe there are a lot of misconceptions about how renewables are used right now and what are the actual benefits.  The current adoption approach is what I would characterize as using renewable energy to reduce GHG generation.  But they are not being used for actual real time grid support.  The actual support is provided by controllable conventional generation resources.  So, at high penetration levels, the renewables need to provide the necessary grid and load support since the controllable generation that are enabling the higher renewable penetration may be forced to retire and no longer be available to provide grid support.   Then, until the renewables can be designed and operated to provide real time support, the grid may go unstable if the conventional resources are retired prematurely.  PV is not available at night and we still have loads at night.  So, until the renewable resources are set up as controllable resources, we may have more and more grid issues.  Electricity is critical to modern life and the US economy depends on it.  We should not muck up the power grid in our attempt to address GHG issues.  Both are important and I believe I presented a method to address GHG issues and grid issues at the same time.
