What the item did not cover is who pays for maintaining the grid and the
generating capacity needed for when solar power and battery backup is
not enough.
When there is not enough sunshine, householders can use the grid to get
power from a remote station (currently using fossil fuel). But the
householder will have to pay for that infrastructure, even if they
rarely use it. A local generator on a micro-grid is an alternative, but
the householders will have to pay to have that installed and maintained.
ps: There are some ways IT can help cope with renewable power
fluctuations. As an example, Canberra researchers tracks clouds, so a
suburb will have a few minutes warning of a cut in solar power:
