Swifty Corporation has decided to invest in renewable energy sources to meet part of its energy needs for production. It is considering

solar power versus wind power. After considering cost savings as well as incremental revenues from selling excess electricity into the

power grid, it has determined the following.

Determine the net present value and profitability index of each project. $($If the net present value is negative, use either a negative sign

preceding the number eg $-45$ or parentheses eg $(45).$ Round present value answers to $0$ decimal places, e$.$g$.125$ and profitability index answers

to $2$ decimal places, e$.$g$.15\mathrm{.}25.)$
