The most recent auction of carbon dioxide (CO2) emissions allowances in the major U.S. northeast regional trading hub reached near record-high prices, as the number of allowances available was reduced. The latest Regional Greenhouse Gas Initiative (RGGI) quarterly auction, held September 6, 2023, resulted in a clearing price of $13.85 per ton … [continued]
U.S. energy-related CO2 emissions drop 25% to 38% below what they were in 2005 by 2030, according to our projections in the Annual Energy Outlook 2023 (AEO2023). We use 2005 as an emissions reference year because the United States’ nationally determined contribution (NDC), submitted as part of the Paris Agreement, calls for a … [continued]
Power generation from wind energy has the benefit of not contributing to global warming or polluting the air. But what is the monetary value of this benefit? Before diving into estimating the societal benefits of wind energy, let’s first look at the amount of carbon dioxide (CO2) emitted into the … [continued]
Nearly half of the energy consumed in U.S. buildings in 2021 was used for heating and cooling, according to modeled estimates in our Annual Energy Outlook 2022 (AEO2022) Reference case. An Issues in Focus analysis on alternative weather assumptions highlights how different long-term weather projections affect space heating and space cooling demand in the U.S. … [continued]
The latest findings from the IPCC paint a grim picture: Despite some signs of progress, the world’s chance of holding global warming to 1.5 degrees C (2.7 degrees F) is shrinking — and with it, our ability to prevent the most dangerous climate impacts. The goal is still within reach if global … [continued]
In 2021, U.S. energy-related carbon dioxide (CO2) emissions increased by 296 million metric tons (MMmt), or 6%, compared with 2020 levels. This increase followed a rise in economic activity and energy consumption once the initial economic impacts of the COVID-19 pandemic began to subside. Despite this increase in total emissions, … [continued]
