Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.

Explanations below

Explanation:

A. Wind power:

In the principle of wind power energy, the wind turbine used in the process has blades that look like propeller. When the wind turns the blade around a rotor, it spins a generator and electricity is being generated.

B. Water power (also called hydroelectricity):

The hydro power process is similar to that of the wind power. At the hydropower plants in different localities, one would notice the flow of water through a pipe, which turns the blades in the turbine, to spin a generator and electricity is being produced.

C. Solar power:

In solar power generation, solar panels are used. The required solar energy is produced when sunlight strikes the solar panels and that converts the solar power into electricity that can be used.

D. Ethanol:

Ethanol is a renewable biofuel which can be made from different things such as grasses, corn cobs and stocks, rice straw, sawdust, and wood chips. During the process, yeast is used to ferment the start and sugars in the corn and sugar cane. The starch is fermented into sugar which can also be fermented into alchohol [ethanol].
