YANTAI, CHINA – AUGUST 4, 2023 – A huge amount of coal is ready for shipment in Penglai Port region … [+] of Yantai Port, East China’s Shandong province, Aug 4, 2023. From January to June 2023, home manufacturing of raw coal turned into 2.3 billion tons, an delay of 4.4%. China imported 220 million many of coal, up 93% 365 days on 365 days.

The is the fifth article in a series on the recently launched 2023 Statistical Overview of World Energy. Earlier articles discussed the trends in world carbon dioxide emissions, the overall highlights of the Overview, the manufacturing and consumption of petroleum, and pure fuel manufacturing and consumption.
Recently let’s discuss coal.
Coal Emissions
In 2022, coal comprised 26.7% of the enviornment’s significant vitality consumption. That turned into in the abet of oil (31.6%), but earlier than pure fuel (23.5%). However, coal turned into accountable for extra carbon dioxide emissions than its fossil fuel counterparts.
Enable me to illustrate.
Fossil fuels are essentially tranquil of carbon and hydrogen. They are hydrocarbons. When hydrocarbons are combusted, the carbon varieties carbon dioxide and the hydrogen varieties water vapor. Coal contains a bigger percentage of carbon than does oil or pure fuel. So, when coal is combusted, it generates extra carbon dioxide per unit of vitality than oil or pure fuel will generate.
In accordance with the Energy Data Administration (EIA), combustion of coal emits on average about 220 pounds of CO2 per million British thermal fashions (BTU) of vitality. When put next, oil emits about 160 pounds of CO2 per million BTU, and pure fuel emits 117 pounds of CO2 per million BTU.
Meaning that for every million BTUs of vitality consumed, in 2022 coal emitted 26.7% time 220 pounds, oil emitted 31.6% times 160 pounds, and pure fuel emitted 23.5% times 117 pounds.
Sum all of it up, and the relative cumulative contributions of these three fossil fuels to carbon dioxide emissions are coal at 43%, oil at 37%, and pure fuel at 20%.
Coal also produces quite a lot of more than a few sinister emissions when burned in strength flowers. Historically, coal flowers emitted quite a lot of sulfur dioxide, which causes acid rain. Rules finally reined in that topic, but coal-fired strength flowers tranquil emit air pollution savor mercury. They even emit extra radioactive parts into the atmosphere than a nuclear strength plant. Thus, there were many regulations passed which beget tried to lower coal’s affect on the atmosphere.
In consequence of the many air pollution issues related to coal, most developed international locations beget moved some distance from coal-fired strength. However because coal is affordable, constructing international locations proceed to count heavily on coal as a provide of strength. Coal consumption in constructing international locations is currently the supreme world driver of rising carbon dioxide emissions.
Coal Consumption
Over the past decade, coal consumption has declined in developed international locations, and grown in constructing international locations.
At some stage in the 38 international locations that comprise the Organisation for Financial Cooperation and Style (OECD), coal consumption has declined by an average annual rate of three.9% over the past decade. In non-OECD international locations, coal has grown at an average annual rate of 1.4%.
Consumption in the European Union (EU) has confirmed the identical downward trend because the OECD. Over the past decade, EU coal consumption has declined at an average annual rate of 4.2%. However, in 2022, coal consumption in the EU reversed direction and grew by 2.0%. This turned into a consequence of Russia’s invasion of Ukraine, and EU international locations changing Russian pure fuel with coal.
The rep result turned into a world delay in coal consumption to the second-highest diploma on drawl, most moving 0.01% below the drawl diploma arrangement in 2014. In actuality, in spite of all of the enviornment’s efforts to in the low cost of carbon dioxide emissions, coal consumption is as excessive because it has ever been.
Global Coal Consumption 1965-2022.
Six of the enviornment’s ten supreme patrons of coal are in the Asia Pacific suppose. China tranquil dominates world coal consumption (and manufacturing) and could well additionally simply seemingly proceed to attain so for just a few years. Below were the enviornment’s Top 10 coal patrons in 2022. “Change” refers to the growth or decline from the old 365 days.
Top 10 Coal Consumers in 2022.
Coal Production
A total lot of the international locations that eat quite a lot of coal also compose quite a lot of coal, so there might perchance be form of a lot of overlap with the old table.
Top 10 Coal Producers in 2022.
The supreme exception is Australia, which is a most important coal producer but most moving the 14th supreme client. Colombia can be a Top 10 producer, however it barely cracks the Top 50 amongst coal patrons.
In the following installment, I will elevate a nearer sight at world nuclear strength trends.
