概述	Executive Summary Comparing the cost of renewable energy options to traditional electricity supply is critical for decision-makers, policy experts, investors, and regulators to determine the most efficient and cost-effective way to supply electricity. The problem is that comparing these costs “apples-to-apples” can be difficult and confusing. That means that businesses, policymakers, and other groups may be choosing an electricity option based on inaccurate or incomplete information. With the cost of renewable energy systems falling globally—particularly large-scale wind and solar energy in the United States—these comparisons will become more and more important. WRI’s new fact sheet, Understanding Renewable Energy Cost Parity, outlines, the accuracy of these comparisons is drastically improved by clearly defining the perspective from which the comparison is being made; the electricity supply options being considered; and what other factors should be taken into account.
结论	Behind-the-meter generation is cost-competitive for end-use consumers when its average cost of energy (calculated from past projects or LCOE) is at least equal to the retail electricity price over a project’s lifetime. In developing economies, this generation unit’s cost-competitiveness is determined by the retail price plus the amount saved in backup generation costs. A power purchase agreement (PPA) option is cost-competitive (and can save end-use consumers money) when the price paid for the electricity is lower than or equal to the retail electricity price over the renewable project’s lifetime or contract. Renewable energy projects can lower the wholesale generation price in the short-term through their low marginal cost of production but is only cost-competitive in the long-run when its average cost of energy (past projects or LCOE) is at least equal to the average wholesale costs when the project is generating power. In the traditional market context, a renewable energy project is cost-competitive (and presents economic savings) against other technologies that provide the same service when it has at least equal average cost of energy (past projects or LCOE) and/or lower risk.
摘要	This factsheet is a simple, go-to resource outlining how electricity supply options (renewable vs. traditional) can be appropriately compared. This publication is the first in a series of three tools to help breakdown these analyses for greater clarity and precision in weighing the cost effectiveness of renewable energy options.
