A.biomass

B. wind

C. Power tower

D. Geothermal hot water

2. Which of the following is not a form of energy?

A. Potential

B. chemical

C. Mechanical

D. Radiant

BIOMASS: Through the process of photosynthesis biomass takes and stores energy from the Sun.

WIND: Winds are caused by differences in pressure and temperature, these are caused by heat energy from the Sun.

POWER TOWER (Solar Tower): Uses reflected solar energy to heat water and generate electricity.

GEOTHERMAL HOT WATER: Comes from the ground and is heated by radioactive decay and heat energy present when Earth coalesced, also heated by solar energy absorbed at the surface.

Strictly speaking, all the options use solar power. Geothermal hot water uses the least and in some cases doesn’t use any, this is the best answer although it’s not strictly correct.

POTENTIAL ENERGY: This is the amount of energy ‘stored’ in something relevant to it’s position. For example, when you draw back on a bow the released energy is imparted into the arrow and it flies forward.

CHEMICAL ENERGY: This is the energy in the chemical bonds of molecules and atoms. If you burn gasoline for example, a chemical reaction takes place and energy is released.

MECHANICAL ENERGY: This is the energy associated with motion (kinetic energy) plus stored energy (potential energy). It’s a measure of the amount of energy of movement plus potential movement.

RADIANT ENERGY: This is the energy that’s radiated outward from something in the form of electromagnetic waves. Sunlight is one example, a nuclear reaction is another.

All four are types of energy and as such there is no answer to your question.
