Question

There are three main ways to make electrons move to create what we call electricity. The major one is using physical movement to turn an axle to turn a generator which makes electrons move. The second is through a chemical process called separated oxidation and reduction, which moves electrons chemically into and out of a wire, better known as a battery. The third is by use of light photons to move electrons. Which of these ways of producing electricity or energy for chemical reactions is the basis for each of the following ?

a. Coal- or natural gas-powered steam plant

b. Nuclear power plant

c. Automobile battery

d. Doped-Silicon cell

e. Solar reflector power plant

f. Tidal or wave generator

g. Hoover Dam

h. Automobile generator

i. Geothermal power generation

j. Wind turbines

k. Photosynthesis
