I disagree with the statement that highly variable sources of generation won't make the grid less stable. The more non-dispatchable variable generation there is the more quickly dispatchable firm generation you need to make up for the power which can suddenly disappear. Electricity systems use the frequency in the short time frame to determine if more or less power is required, big changes in generation cause changes in the frequency, which is one aspect of grid stability.

good points otherwise!
