电力部门约占美国二氧化碳（CO2）排放量的40%，减少发电产生的CO2排放量是美国减少温室气体排放战略的重要组成部分。为了实现这一目标，已经提出了几项关于清洁能源标准（CES）的建议，其中包括奥巴马政府支持的一项建议，该建议要求到2035年将目前约40%的清洁电力水平逐步提高到80%。本文着眼于这种政策对电力部门二氧化碳排放量的影响，用于供电的技术组合，电力价格和清洁能源信用的区域流动。CES将在2013年至2035年期间减少30%的累积二氧化碳排放量，并大幅减少传统煤炭的发电量。该政策还导致全国电价相当温和的上涨，但这掩盖了各地区的各种影响。
The electricity sector is responsible for roughly 40% of U.S. carbon dioxide (CO2) emissions, and a reduction in CO2 emissions from electricity generation is an important component of the U.S. strategy to reduce greenhouse gas emissions. Toward that goal, several proposals for a clean energy standard (CES) have been put forth, including one espoused by the Obama administration that calls for 80% clean electricity by 2035 phased in from current levels of roughly 40%. This paper looks at the effects of such a policy on CO2 emissions from the electricity sector, the mix of technologies used to supply electricity, electricity prices, and regional flows of clean energy credits. The CES leads to a 30% reduction in cumulative CO2 emissions between 2013 and 2035 and results in dramatic reductions in generation from conventional coal. The policy also results in fairly modest increases on national electricity prices, but this masks a wide variety of effects across regions.
