Which of the following is not a renewable source of energy? wind nuclear solar hydroelectric - Leaving Cert Physics - Question b - 2007

To determine which option is not a renewable source of energy, we need to assess the following options:

1. Wind Energy: Wind energy is produced by converting wind currents into electricity using wind turbines. It is considered a renewable source because wind is a naturally replenishing resource.
2. Nuclear Energy: Nuclear energy is generated through nuclear reactions, primarily fission. This process does not involve renewable resources and is, therefore, considered non-renewable.
3. Solar Energy: Solar energy is harnessed from sunlight using solar panels. It is a renewable resource, as sunlight is abundantly available and easily replenished.
4. Hydroelectric Energy: Hydroelectric power is produced by harnessing the energy of flowing water. It is also a renewable source of energy, as water cycles naturally in the environment.

Based on the analysis, nuclear energy is the option that is not a renewable source.
