BOSTON, July 21, 2021 /3BL Media/ - U.S. power sector carbon dioxide emissions fell 10% between 2019 and 2020 according to a new analysis released today. This is the largest year-over-year decrease since the Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States report was first released in 1997.
While the coronavirus pandemic may have been a contributing factor, the drop in emissions in 2020 is part of a long-term trend fueled by increased renewable generation and coal-to-gas transitions. This year’s report highlighted several dramatic shifts, as the share of power produced by non-hydro renewables jumped 20% from 2019 levels and the share from coal decreased by roughly 17%.
“Industry-wide, the pace of decarbonization is picking up, and as renewables come online to displace fossil fuels, we have the opportunity to accelerate that trend,” said Dan Bakal, senior director for electric power at Ceres. “The growth in renewables has allowed us to separate economic growth from emissions, and this year represents one of the most dramatic decoupling points that we have seen.”
Power companies face intensifying pressure to decarbonize amid a steady drumbeat of net zero commitments and regulatory actions. In April, President Joe Biden announced a nationwide goal of 100% carbon-free electricity by 2035, and his administration faces rising calls from a variety of sources, including power companies, to set an interim goal of 80% clean energy by 2030.
A month later, a report from the International Energy Agency (IEA) modeling pathways consistent with limiting warming to 1.5°C called for all developed countries to reach net zero CO2 emissions by 2045. Under that scenario, renewables would provide 60% of all generation by 2030 and 90% by 2050.
“The power sector continues its march away from fossil fuels, replacing them with clean sources like wind and solar. But there is still a ways to go,” said Starla Yeh, director of the Policy Analysis Group in the Climate & Clean Energy program at NRDC. “We’ll need to at least double the share of clean electricity in the generation mix by 2030 to meet the administration’s goals for the sector of 80% clean by 2030 and 100% by 2035. Now is the moment for the Biden Administration to act. It can accelerate this progress by putting in place a performance standard – either via new legislation or EPA action.”
The benchmarking analysis examines and compares key air pollutant emissions from the 100 largest U.S. power producers, including nitrogen oxide (NOx), sulfur dioxide (SO2), carbon dioxide (CO2), and mercury. This is the 17th edition of the report, marking a consistent record of the sector’s environmental performance and progress. It uses publicly reported generation and emissions data from the U.S. Energy Information Administration and the U.S. Environmental Protection Agency.
The benchmarking report consistently demonstrates that reduced emissions and economic growth can go hand in hand. Between 2000 and 2020, power sector CO2 emissions decreased 37% while GDP grew 40%. Over the same period, generation from non-hydro renewables more than doubled. In 2020, power sector CO2 emissions were roughly 40% below the industry’s 2007 peak. Alongside the steep annual decline in CO2 emissions, power sector SO2 and NOx emissions have decreased 93% and 85% from 2000 levels, respectively.
While many of the largest power producers have announced commitments and specific strategies to reduce their carbon emissions, achieving the type of rapid decarbonization embedded in company and country commitments will require increased ambition from power companies. Electricity is expected to account for a growing share of energy consumption in the U.S. as the transportation sector and other end uses electrify, the report explains, making a clean power grid a critical part of the pathway to the net zero economy.
“As we enter our third decade of voluntary emission reduction commitments, Entergy takes pride in its leadership of the electric utility industry’s clean energy transformation while recognizing the work we still must do,” said John Weiss, Entergy’s vice president of sustainability and environmental policy. “We are focused as an organization on reducing the carbon footprint of our power generation portfolio, both by ensuring the continued, safe operation of our carbon-free nuclear fleet and significantly expanding our renewable generation assets. At the same time, we’re working aggressively to accelerate beneficial electrification of other sectors through innovative cross-industry partnerships. The report is a critical resource because it allows all of our stakeholders to accurately track, and hold us accountable for, changes in our emissions performance.”
In 2020, zero-carbon power resources produced 38% of all power in the U.S. — an all-time high and continuation of an upward trend. Zero-carbon power increased 6% as a share of total production between 2019 and 2020.
“The Benchmarking Air Emission report is an important measure of the progress we have made in addressing climate change by maintaining investment in renewable energy and existing carbon-free nuclear resources,” said Kathleen Barron, Exelon’s executive vice president of government and regulatory affairs and public policy. “As the nation’s largest producer of zero-emission electricity, we believe it’s critical that policymakers and power companies work together to ensure that competitive power markets recognize the value of new and existing clean energy sources that are essential to addressing the climate crisis and reducing the health impacts of air pollution, which disproportionately affect underserved communities.”
The report also includes extensive analysis of company-level emissions and production data, based on 2019 numbers. The 100 largest power producers in the United States collectively accounted for more than 80% of the sector’s total generation and reported air emissions across nearly 3,500 owned power plants. Fuel mix, emissions, and emission rates still vary widely between companies.
Other key findings from the report include:
- For the electric sector overall, power plant SO2 and NOx emissions were 95% and 88% lower, respectively, in 2020 than they were in 1990 when Congress passed major amendments to the Clean Air Act.
- For the fifth consecutive year, natural gas was the leading source of electricity generation in the U.S. (40%), followed by nuclear (20%).
- Non-hydro renewables made up 11% of total U.S. generation in 2020. Of that, 20% came from solar, 76% from wind, and 4% from geothermal sources.
- Power plant mercury air emissions, as reported to the EPA’s Toxic Release Inventory database, have decreased 92% since 2000. The first-ever federal limits on mercury and other hazardous air pollutants from coal-fired power plants went into effect in 2015.
