O Solar → Electric

Answer 1

In a photovoltaic cell, the correct order of energy transformations to produce electricity is directly from Solar energy to Electric energy, without intermediate conversions to heat or kinetic energy.

Step-by-step explanation:

The correct order of energy conversions necessary to form electricity from solar panels is Solar → Electric. In a photovoltaic cell, solar energy is directly transformed into electrical energy without the intermediate steps of heat or kinetic energy transformations. This process leverages the photoelectric effect, where solar energy, in the form of photons of light, excites electrons in a semiconductor material, creating an electric current. Photovoltaic cells are designed to convert sunlight directly into electricity, which can then be used for a variety of applications, such as running an electric motor. It's important to clarify that while solar energy can also be used to generate heat, which in turn can produce steam to drive turbines in Concentrating Solar Power (CSP) systems, this describes a different technology rather than the direct conversion process that occurs in photovoltaic cells.

Answer 2

The correct order of energy conversions needed to form electricity from wind is Wind → Kinetic → Electric.

How is the process of transforming energy through the winds?

The basic operating principle of wind turbines is through the transformation of the kinetic energy of the winds into electrical energy at the generator terminals. The wind moves the blades and turns the rotor, which transmits the rotation to the generator, which, in turn, converts this mechanical energy into electrical energy.

With this information, we can conclude that the correct order of energy conversions needed to form electricity from wind is Wind → Kinetic → Electric.
