A PlayStation will, if streaming video, consume about 150 Joules of energy per second
(J/s). A power plant must consume much more than that in order to supply the
PlayStation with enough energy. Look at the image below to see the energy
transformation diagram. Calculate the efficiency of the two conversions. Round to the
nearest tenth.
