Electricity

Paula and Daniel have discussed contracts for electricity. They might change suppliers of electricity.

While Paula and Daniel know how to make and control fire, they purchase electricity. Daniel says that human control of electricity is of equal importance as human control of fire. I have got no reason to doubt him, even though I do not know much about electricity. It provides heat and light, et cetera, which is good, I just do not know how. It is good to have humans who know.
