Following from McRover's post, in my view a lot could be done to encourage households to install solar collectors. Apart from the fact that going to solar hot water would make a substantial decrease in power use, encouraging installation of photo-voltaic collectors to supply the house and sell extra power to the grid has the advantage that it would forestall the need not only to build new coal fired power plants, but also reduce the need to upgrade the network. These exist at present, but the biggest disincentive is that currently they sell power back to the grid at base load rates - even if the power is supplied at peak times. With smart meters there is no need for this.
As far as fuel supplies go, Australia at least has vast supplies of natural gas, including coal bed methane. It also has even more vast supplies of coal, which can be transformed to synthetic natural gas or coal to liquid processes such as Fischer-Tropsch, or gasified in-situ. This technology is in place today, being used to some extent, for example coal to liquids is being used in South Africa, having been established during sanctions, and there are coal to diesel plants and in-seam gasification on an experimental basis in the USA. The only problems are cost and carbon emissions - but to say that fuel will become unavailable in the foreseeable future is inaccurate. Expensive, yes.

PS I do not supply power to the grid, but run entirely on solar and wind power, so I do know a bit about it. There is at least one solar installation locally that supplies surplus to the grid.
