The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.)

Why SF₆ emissions from the renewable energy sector should not

Feb 10, 2020 · Renewable energy installations require more switchgear in the electricity grid than fossil fuels, because it takes more solar panels and wind turbines to produce the same electrical output as a single coal power station. So as renewable power generation grows, emissions of SF₆ to the atmosphere should grow too.Get price
