May 20, 2022--Researched by Industrial Info Resources (Sugar Land, Texas)--U.S. energy-related carbon dioxide (CO2) emissions increased 6% in 2021, after a jump in economic activity and energy consumption as initial impacts of COVID-19 began to wane, according to the U.S. Energy Administration (EIA). But many U.S power utilities have pledged net-zero carbon by 2050, and their efforts to do so could keep energy-related emissions at lower levels moving forward. Industrial Info is tracking $31.4 billion worth of renewable-energy generation projects that are under construction in the U.S. Those utilities include <a href='https://www.duke-energy.com/home' target='_blank'>Duke Energy Corporation</a> (<a href='https://www.nyse.com/quote/XNYS:DUK' target='_blank'>NYSE:DUK</a>) (Charlotte, North Carolina), <a href='https://www.southerncompany.com/sustainability/net-zero-and-environmental-priorities.html' target='_blank'>Southern Company</a> (<a href='https://www.nyse.com/quote/XNYS:SO' target='_blank'>NYSE:SO</a>) (Atlanta, Georgia), <a href='https://www.sempra.com/' target='_blank'>Sempra Energy</a> (<a href='https://www.nyse.com/quote/XNYS:SRE' target='_blank'>NYSE:SRE</a>) (San Diego, California), <a href='https://www.dominionenergy.com/' target='_blank'>Dominion Energy Incorporated</a> (<a href='https://www.nyse.com/quote/XNYS:D' target='_blank'>NYSE:D</a>) (Richmond, Virginia) and <a href='https://www.wecenergygroup.com/' target='_blank'>WEC Energy Group</a> (<a href='https://www.nyse.com/quote/XNYS:WEC' target='_blank'>NYSE:WEC</a>) (Milwaukee, Wisconsin).
