<span>Nuclear power plants produce radioactive
waste that must be stored properly. It is very impossible for a nuclear power plant
to have no waste at all since lots of chemicals are used to create the process
as it gives energy to other machines. Nuclear energy can be used to power all
of the above choices. Radioactive waste can not be released into local water
supplies since the wastes are very radioactive and may cause mutation to the
fishes and bioaccumulation which will affect humans as well. It will also cause
air pollution if the chemicals are not stored properly.</span>
C. Space.
Radiation is a process by which heat energy is transferred through space.
