The externalities for wind and solar is the reserve energy that currently consumer expects governments (in EU) to supply and pay for. It is the most expensive form of externalities in the grid, it is one of the dirtiest, and since the government is paying for it it is also the most subsidized. This socialization of costs is sadly mostly unknown to the consumer. Governments could try moving the costs closer to the consumer by putting the costs onto the power company, forcing them to either cut off consumer when demand exceed supply or build enough storage to cover periods of suboptimal weather conditions.
