From Wikipedia:
A radioisotope thermoelectric generator (RTG, RITEG) is an electrical generator which obtains its power from radioactive decay. In such a device, the heat released by the decay of a suitable radioactive material is converted into electricity by the Seebeck effect using an array of thermocouples. RTGs can be considered as a type of battery and have been used as power sources in satellites, space probes and unmanned remote facilities. RTGs are usually the most desirable power source for unmanned or unmaintained situations needing a few hundred watts or less of power for durations too long for fuel cells, batteries and generators to provide economically, and in places where solar cells are not viable.
Fuels that can be produced at any time are typically referred to as "dispatchable" fuels. These fuels can be generated or utilized on demand, providing flexibility in energy supply. Common examples include fossil fuels like natural gas, as well as renewable sources like biomass and certain types of hydrogen. Their ability to be produced or accessed as needed makes them crucial for maintaining energy reliability and stability.
They are called electrical conductors
What we normally call heat or thermal energy.
Cells need many chemicals, but perhaps you are thinking of DNA.
This is an energy drink.

The energy released in a radioactive decay arises because the nucleus is moving from one energy level to a lower energy one. The link below gives a good outline explanation in the Explanation section.
Materials produced when a volcano erupts are called volcanic products or volcanic materials. These can include lava flows, ash, gases, and volcanic rocks such as pumice and obsidian.
Something that is radioactive is called a radionuclide.
Electrical energy originates from the movement of charged particles, such as electrons, through conductive materials. In the material creation, electrical energy is produced by natural processes like electromagnetic induction, chemical reactions in batteries, and the flow of electrons in power plants.
Acoustics is the general field, and ranges from human anatomy, to architectural acoustics, to building materials, and music and speech.
Materials that help to keep temperature constant and do not absorb thermal energy are called insulators. These materials are often used in buildings to prevent heat loss or gain. Examples of insulating materials include foam, fiberglass, and cellulose.
Hydropower is the alternative energy resource that uses water to create energy. This renewable energy source captures the energy produced by falling or flowing water to generate electricity.
