Carbon emissions from U.S. power generation fall to 25-year low

. . . Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA). The EIA attributes this partly to the short-term impact of mild weather, but also to the replacement of fossil fuels with renewable energy sources.

In addition to noting the 25-year low for carbon emissions in the first six months of the year, the EIA believes the full-year total for 2016 will be the lowest since 1992. U.S. energy-related CO2 emissions totaled 2,530 million metric tons in the first six months of 2016, and the EIA expects the total for the entire year to be 5,179 million metric tons.

The agency attributes the decrease in emissions to both weather and changes in the energy-consumption mix. Thanks to mild weather last winter, the first six months of 2016 saw the lowest number of "heating degree days"—an indicator of home heating demand—since at least 1949, according to the EIA. . . .

Overall, the total primary energy consumption for the first six months of 2016 was 2 percent lower than the same period in 2015. At the same time, coal and natural gas consumption decreased compared to the first six months of 2015. Coal saw the more dramatic decline, with consumption decreasing by 18 percent, compared to 1 percent for natural gas. The decreases for these fossil fuels more than offset a 1 percent increase in petroleum use, notes the EIA, which attributes the increase to low gasoline prices.

While coal and natural gas declined, use of renewable-energy sources increased 9 percent during the first six months of 2016, compared to the same period in 2015. . . .
