Companies that want to build new nuclear inevitably meet opposition groups, so it is always a struggle to get new nuclear built. However the realisation that fossil fuels are going to get scarcer and hence more expensive, and that producing more CO2 may be bad for the planet, is I think gradually changing attitudes.
Using nuclear energy is possible, and in fact being done. It has been done since the 1940s. The first nuclear electric plant came on line some time after that, but I worked at one in the 1980s.
work is being done when you use energy
Energy produced by nuclear power cannot be stored, it has to be used as soon as it is produced. This is done by producing steam from the thermal energy released and using this in a conventional power plant
Every atom contains nuclear energy inside it. That nuclear energy can be released by splitting the atom. The uranium atom is one of the ones that is easier to split. Usually to release the nuclear energy atoms are collided with each other which breaks them releasing the nuclear energy. This is done in a machine called a particle accelerator in which atoms are fired at near the speed of light and when they collide and split they release nuclear energy. I Hope that answers your question.
getting lots of energy is done for peaceful reasons and kill lots of people if done in war
As usual these get inter-twined. Nuclear energy originates from the nucleus, when U235 fissions or splits, energy is released because the resulting products have lost mass, and energy = mass x c2. This energy appears as kinetic energy of the fission fragments, and to a smaller extent as a gamma ray. The fission fragments recoil and their kinetic energy is lost and appears as thermal energy in the uranium fuel. The gamma is also absorbed in the reactor. So it is basically a potential energy, but you can regard all mass as a potential energy through E = mc2.
nuclear power is going to be around for much longer, more fission reactors will be built to compensate in the increase in energy usage and more research is being done to make fusion energy which will replace fission reactors(this is quite a while yet before fusion reactors can be used to produce use usable energy for long periods of time).
I don't know of any way to do this. Nuclear energy simply provides heat, so could conceivably be used to drive chemical reactions, but I don't think this has ever been done.

YesIt is true that solar energy can be changed into thermal energy without any work being done. The solar energy is thermal energy from the sun.
Nuclear power does not produce emissions like CO2 and sulphur dioxide that are produced when fossil fuels are burned.
They both utilise nuclear fission, in which nuclei of U-235 or Pu-239 are split apart which releases enormous energy. In nuclear power this is done at a comparatively slow controllable rate, in a weapon you want a very rapid reaction to create a huge blast of energy.
