EL panels: those exist, you're probably staring at one right now, it's behind your LCD. LED lighting is also fairly common these days. It's certainly possible for exactly what is described to be installed in a house, it's just not particularly desired.
Adjustable transmissivity glass is a reality but not yet practical enough for it to be ubiquitous.
Radioactive batteries very much do exist, they are called RTGs, and they have given great benefit to spacecraft and other equipment. They power the Curiosity rover, for example. However, they are too impractical and too expensive to be used for ordinary household equipment. This would be true even without the radiation problems of RTGs, which are, of course, significant.
We should have moon colonies by now and ironically the Apollo program is probably the most at fault for that. In order to make it happen a lot of political capital was expended, creating a particular political situation which has become a permanent institution within NASA manned spaceflight (specifically, billions of federal dollars flowing into a few very specific congressional districts which has continued through Apollo and Shuttle programs and now SLS/Orion). If NASA had instead concentrated on a slower program which built up long-lived infrastructure and optimized toward lowering launch costs and increasing capabilities then we would easily have cities (or at least towns) in orbit and moonbases, and Mars bases.

Asimov says windows "will be polarized to block out the harsh sunlight." That sure sounds to me like putting LCD tech in a window, sans backlight and Bayer filter. We don't use the tech architecturally, but we certainly mass-produce it at the sizes needed for use as window panes. And passive photochromic lenses are also commodity items. Either one is completely practical for integration into a window, there just isn't currently demand to do so.
The cold war ended, and there was no longer a need to prove that we could send something up into space and rain down fiery death upon anyone on the planet. Hence, no more space program.
That's not entirely true. Even after the end of the Cold War the manned spaceflight program in the US has received several billion dollars a year in funding. It's more than possible to operate a quite proficient manned exploration and colonization program with funding at that level. The problem is more that NASA and congress have been completely ineffectual at using resources effectively. The ISS was almost entirely built and launched after the end of the Cold War, and it's total cost was at least 50% greater than the entire Apollo program, for example.
