Answer 1

The Correct answer is nuclear energy

Key Points

Nuclear energy is the energy that is derived from the nuclear reactions involving radioactive isotopes.
This form of energy is released through processes like fission (splitting of atomic nuclei) and fusion (joining of atomic nuclei).
In nuclear fission, isotopes such as uranium-235 and plutonium-239 are commonly used as fuel, and their nuclei are split to release a large amount of energy in the form of heat.
The heat generated is used to produce steam, which drives turbines to generate electricity.
Nuclear energy is considered a powerful source of energy, with a much higher energy output per unit of fuel compared to traditional fossil fuels.
It is used in nuclear power plants worldwide to generate electricity and in other fields like medicine and industry for purposes such as cancer treatment and radiography.

Additional Information

Thermal Energy
- Thermal energy refers to the energy derived from the heat produced by burning fuels or from other heat sources like geothermal energy.
- Unlike nuclear energy, thermal energy involves combustion or heat exchange processes, such as those in steam engines or fossil fuel power plants.
Solar Energy
- Solar energy is the energy derived from the Sun’s radiation, which is harnessed through technologies like solar panels and solar thermal collectors.
- This renewable energy is not related to nuclear reactions and is considered an environmentally friendly alternative.
Geothermal Energy
- Geothermal energy is the heat energy derived from the internal heat of the Earth.
- It is produced by the natural radioactive decay of elements inside the Earth, but it is not the same as nuclear energy, which involves controlled nuclear reactions.
