I'd like to see it pared down to the extent little, if any, grid is necessary. Localized, personal, nuclear power. Might take a while, but it could be done.
You might never be able to hook a nuke up to your home but the day that you can get off the grid by buying an efficient fuel cell that uses a variety of fuels including natural gas isn’t too far away.
Large scale nukes aren’t going to happen because the Dems closed out the Yucca mountain storage facility. There are however small nukes being developed that can be buried in the ground and power about 25,000 homes or provide power for industrial processes in remote locations such as the tar sands fields in Canada. The first of these should be activated within the year providing they aren’t banned as well.
