Every million BTUs released from burning coal releases an average of 208 pounds of CO2 (see note below). Since a ton of coal has 20.025 million BTUs, that means it creates 4,172 pounds of CO2 when it is burned. Running our 100-watt bulb for one year will produce 1,670 pounds of CO2.
How much CO2 is produced per kWh from a coal power plant?
| Electricity generation | million kWh pounds per kWh | Coal 947,891 2.21 | Natural gas 1,358,047 0.91 | Petroleum 15,471 2.13 |

Do coal power plants release carbon dioxide?
Those existing coal and other fossil fuel-fired power plants emit billions of tons of CO2 each year and account for about 26 percent of global greenhouse gas emissions — double that of the transportation sector.
How much CO2 do power plants release per year?
Globally, power generation emits nearly 10 billion tons of CO2 per year. The U.S., with over 8,000 power plants out of the more than 50,000 worldwide, accounts for about 25 percent of that total or 2.8 billion tons.
Why is coal the worst energy source?
Coal contains more carbon than other fossil fuels such as oil and gas, resulting in the release of greater quantities of carbon dioxide into the atmosphere when it is burned. Coal therefore contributes more to climate change than any other energy source.
What are disadvantages of coal?
- Coal is nonrenewable. ...
- Coal contains the most CO2 per BTU, the largest contributor to global warming.
- Severe environmental, social and health and safety impacts of coal mining.
- Devastation of environment around coal mines.
- High cost of transporting coal to centralized power plants.
Does electricity emit CO2?
In 2019, total U.S. electricity generation by the electric power industry of 4.13 trillion kilowatthours (kWh) from all energy sources resulted in the emission of 1.72 billion metric tons—1.90 billion short tons—of carbon dioxide (CO2). This equaled about 0.92 pounds of CO2 emissions per kWh.
How many tons of CO2 do companies produce?
Total Emissions in 2019 = 6,558 Million Metric Tons of CO2 equivalent.
How much CO2 is emitted when natural gas is burned?
| Coal (anthracite) 228.6 | Diesel fuel and heating oil 161.3 | Gasoline (without ethanol) 157.2 | Propane 139.0 | Natural gas 117.0 |

Is coal the dirtiest fossil fuel?
Coal is the dirtiest of the fossil fuels and responsible for over 0.3C of the 1C increase in global average temperatures – making it the single largest source of global temperature rise. Oil releases a huge amount of carbon when burned – approximately a third of the world’s total carbon emissions.
What is the cleanest type of coal?
Anthracite is used for space heating as it is one of the cleanest types of coal to burn—producing less smoke than other types. Its clean burning properties allows anthracite to burn longer than wood, making it appealing to use in home heating stoves.
Why we should stop using coal?
Coal-fired power plants have been linked to developmental defects in 300,000 infants because of their mothers’ exposure to toxic mercury pollution. Asthma rates are skyrocketing in communities exposed to particulates from burning coal, and now one out of ten children in the U.S. suffers from asthma.
What are 3 disadvantages of using coal?
- Mining coal is incredibly destructive to the environment. ...
- Coal is actually radioactive. ...
- Burning coal emits harmful substances. ...
- Coal generates carbon emissions. ...
- Coal mining and combustion contributes to climate change. ...
- Coal is a non-renewable energy source. ...
- Coal mining is a dangerous industry.
What are 5 advantages of coal?
- It is available in an abundant supply. ...
- It has a high load factor. ...
- Coal offers a rather low capital investment. ...
- Carbon capture and storage technologies can reduce potential emissions. ...
- It can be converted into different formats. ...
- Coal can be used with renewables to reduce emissions.
What is the major disadvantage of using coal?
The major disadvantage of coal is its negative impact on the environment . Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
What is the biggest contributor to global warming?
Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.
