Its high spontaneous fission rate.
Americium is scarce and expensive.
Fission power is the only realistic source of ecologically sound power, for at least the next 50 to 100 years.
The breakup of large nuclei into two nearly equal fragments is called nuclear fission. It sometimes produces neutrons, protons or other nuclei. This is important in nuclear reactor and bombs, where neutrons emitted from one fission event cause other nuclei to fission, releasing more neutrons and so causing chain reaction. If this chain is controlled then you have a nuclear reactor whose heat can be used to boil water and generate electricity. If the chain is uncontrolled it causes a nuclear explosion.
We generally consider nuclear fission as the "splitting" of atoms. In this process, a large atomic nucleus splits into two smaller nuclei. The smaller nuclei are called fission fragments, and they are radioactive. Making nuclear energy, which we do in nuclear reactors, results in the production of large quantities of highly radioactive fission products. These byproducts require that we cool the spent fuel for long periods, and also that we store it for centuries so that the radioactive materials have a chance to decay and become less hazardous.
No one currently uses nuclear fusion, as the technology has not yet been developed to actually put nuclear fusion into practical use. The only place nuclear fusion is used on a large scale is in nuclear weapons...bombs.
Fission is used for electricity because it can generate a vast amount of energy (electricity) for very little fuel. Fission also emits no greenhouse gases, or gas pollutants of any kind (all of its waste is solid or suspended in a liquid), thus making it possible to dispose of in safe locations (as opposed to just released into the air with coal plants).

That would be Americium (Am). No, I am not making this up. It is an element that cannot be found in nature due to its nuclear instability, and can only be created synthetically.

Read "The making of the Atomic Bomb" by Richard Rhodes, it will answer all your questions better than could ever be done here.

Yes, plutonium IS used in nuclear weaponry it is one of the two fission fuels (the other is enriched uranium) that provide the energy for the explosion. Traditionally plutonium has been the prefered fission fuel, as it is less expensive to manufacture in quantity with nuclear reactors than is enriching uranium and also has a lower critical mass than enriched uranium. However because plutonium is manufactured in reactors it is "contaminated" with heavier plutonium isotopes that have high rates of spontaneous fission and are more radioactive, making it unsuitable for a few bomb designs for which enriched uranium must be used.

A nuclear reaction - either fusion or fission - is required to turn matter into energy.
Weapons are designed to explode and produce blast waves to destroy targets. Peaceful nuclear energy uses a controlled steady fission reaction to produce heat, which then is used to generate electricity
Fuel rods containing uranium are placed close together, causing a nuclear reaction as the uranium fissions. This produces heat. Heat is transferred to cooling water, making steam. Steam spins a turbine onnected to a generator.
