Three old coal boilers, including two vintage 1944 stoker boilers and a 1955 vintage steam boiler, will be permanently retired in early September.
The majority (69%) of primary energy imported into the United States in 2018 was crude oil, with petroleum products and natural gas also having significant shares, according to the US Energy Information Administration (EIA). Small amounts of biofuels, electricity, and coal were also imported. Coal category includes coal coke.
Siemens Energy will provide compressor trains for three LNG (liquefied natural gas) plants in China for liquefying synthetic natural gas produced from coal. The Houma Tongsheng Yitong Natural Gas Company will operate one of the plants. These plants have a capacity of half a million standard cubic meters of gas per day.
In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. The United States now emits less CO 2 from coal than from motor gasoline.
Stay-at-home orders, travel restrictions, and work-from-home arrangements reduced demand for motor gasoline, distillate fuel oil (primarily consumed as diesel), and jet fuel. Natural gas accounts for the second-largest share of energy-related US CO 2 emissions, at 33% of the 2019 total.

The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% Natural Gas.
In the United States, emissions associated with the consumption of petroleum fuels—motor gasoline, distillate, jet fuel, and more—have consistently made up the largest portion of CO 2 emissions. Natural gas surpassed coal to become the most prevalent fuel used to generate electricity in the United States in 2016.

Carbon intensity changes in the electric power and industrial end use sectors. In 2009, the carbon intensity of the electric power sector decreased by nearly 4.3%, primarily due to fuel switching as the price of coal rose 6.8% from 2008 to 2009 while the comparable price of natural gas fell 48% on a per Btu basis.
over the prior year, according to the EPA’s newly published Inventory of US Greenhouse Gas Emissions and Sinks: 1990–2013. By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution. MMT CO 2 Eq.) Total US emissions have increased by 5.9% from 1990 to 2013.

The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. The electric truck is relatively more cost-effective on the NYCC and when VKT demand is higher. Cost-competitiveness of the electric truck diminishes in drive cycles with higher average speeds. Credit: ACS, Lee et al.
They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Over an array of possible conditions, the median TCO of electric trucks is 22% less than that of diesel trucks on the NYCC. However, the cost-competitiveness of the electric truck diminishes in drive cycles with higher average speed.

Climate Change Coal Emissions Fuel Efficiency'
Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
