Answer:
'Renewable' energy refers to energy from sources that are constantly replenished - like the water for hydroelectric dams that is topped up by the rain, or the sunlight that reappears every day for solar panels. Because nuclear power uses up radioactive fuel, it is not renewable in the same way.
Step-by-step explanation:
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
