Question

Most of the sources of energy we use represent stored solar energy. Which of the following is not ultimately derived from the Sun's energy?

• A. Geothermal energy
• B. wind energy
• C. nuclear energy
• D. biomass

Answer 1

The correct option is C

nuclear energy

The correct option is C.

Explanation of the correct option:

1. Nuclear reactions release energy through either fission or fusion. Atoms unite in nuclear fusion to create a bigger atom. Atoms split during nuclear fission in order to create smaller atoms by releasing energy.
2. Nuclear fission is the source of energy in nuclear power plants.
3. Nuclear reactions may generate enormous amounts of energy even in the absence of sunlight.

Explanation of the incorrect options:

Option A:

1. Heat from the earth is known as geothermal energy.
2. The Greek words geo (earth) and therme are the source of the word geothermal (heat). Due to the ongoing production of heat deep inside the ground, geothermal energy is a renewable energy source.
3. Geothermal energy is used to produce electricity, heat buildings, and provide hot water to people.

Option B:

1. Utilizing the kinetic energy provided by moving air, wind energy is used to generate electricity.
2. Using wind turbines or other wind energy conversion technologies, this is converted into electrical energy. Wind strikes a turbine's blades first, turning them and the turbine attached to them.

Option D:

1. Because biomass is organic, it is composed of materials derived from living things like plants and animals.
2. Plants, wood, and garbage are the most typical biomass materials used for energy. Biomass feedstocks are what they are. A non-renewable energy source that uses biomass is possible.

Final answer: Nuclear energy is not derived from Sun's energy.
