Question: Assume electricity is generated by three technologies: a base load technology with cost function C b (x b ) and proportional emission coefficient b
Assume electricity is generated by three technologies: a base load technology with cost function Cb(xb) and proportional emission coefficient αb; gas turbines with cost function Cg(xg) and emission coefficient αg< αb; and an emission-free renewable energy source with cost function Cr(xr). All cost functions are convex, and there is a total emission cap of L. The inverse demand function for electricity is given by P(X).
(a) Characterize the optimal allocation given the emission cap.
(b) Investigate the comparative static effects of lowering the emission cap on quantities, total output, price, and the percentage of renewable energy, denoted by β=xr/(xb+xg+xr).
(c) Assume now that in addition to the emission cap there is a quota for renewable energy. Show that a quota raises the total cost of electricity production.
