This document summarizes key topics in electricity pricing and environmental economics:
- The levelized cost of electricity (LCOE) is the price required to equate the net present value of revenue from electricity production with the net present value of production costs over the lifetime of a generating asset. LCOE is important for policy decisions but difficult to estimate due to uncertainties.
- Externalities like environmental costs are not included in LCOE but should be through "shadow pricing" to properly evaluate generation options.
- Subsidies have been used to promote renewable energy but a better approach may be taxing "brown" or polluting power to reflect externalities rather than just making "green" power artificially
