Dave,
It seems to trouble people to think that NG would be backing up renewable energy. Even now many NG peak plants are only used at <10% capacity, so we may have a situation with expanding NG peak capacity but less NG being used for both heating and electricity generation. Some coal fired electricity rather than being retired may also be kept in reserve as back-up for example for peak summer demand.

Any realistic transition roadmap would read just so. For example, in the US Southeast, little renewable energy is available in the summer when A/C is running flat out, so while some renewable can be shipped in, coal plants would likely be needed unless supplanted by nuclear.

Of course there is: plenty of sunshine.
Especially during noon peak hours this may produce plenty of photovoltaic electricity. Or the solar heat may be converted directly to cold for air conditioning using sorption technology.
The problem is not the technology - nor the economical viability as soon as prices went down due to mass production. The problem is the same that the IEA is complaining about oil production: lacking investment.
