It can be very misleading to compare the energy costs for wind and solar to the energy costs for more conventional generation technology and assume the difference is the cost of providing for “clean” energy.There are a bunch of comments that are really good, too.
The power grid requires so much more support than the injection of energy. Unfortunately wind and solar do not provide support “services” as well as many other generation resources do. Accounting and providing for these extra “services” should be part of any comparison of resource types and inform any directives or plans impacting the provision of electric power. To the degree that wind and solar resources make up a larger portion of the supply mix, significant costs will be incurred to maintain system functionality and reliability. This posting is focuses solely on how various resources impact just one of these “services”, the balancing of system loads and resources.

Renewable energy will mess up the power grid
Great in-depth article that shows that an amp from solar is not at all the same as an amp from coal generation. And that an amp from coal isn't the same as an amp from gas.
