10. (8 points) Suppose a new carbon price raises the price that consumers pay for electricity from fossil fuels. Now consider the perfectly competitive market for renewable energy, which is a substitute for electricity from fossil fuels. For the purposes of this question, suppose renewable energy does not generate carbon emissions. In an analysis of how the carbon price will affect the renewable energy market, an economist makes the following claims: "By raising the price of a substitute, a carbon price will raise the price of renewable energy in the short-run.

Use graphical analysis to illustrate and explain the economist's claims
