Question by Michael: what is the cost of one Kilowatt-hour of coal and 6 different energies?
This is for an engineering project and this is all the information the teacher gave me, so sorry if it is missing stuff.

Should that be “cost *in* 6 different energies”? In terms of conservation of energy the kilowatt hour of electricity starts out as potential thermal energy in the coal. Then it’s burned as kinetic thermal energy, which is used to boil water which I guess would be chemical energy since it’s inducing a phase change. The steam is used to move a turbine with mechanical energy, the turbine moves magnets with elastic energy, and the magnets induce an electric current which is electromagnetic energy. That’s six.
