How much carbon dioxide is produced when different fuels are burned? emits 1.0 kg carbon dioxide for generating one kilowatt hour of electricity. Fuel is not equal to fuel - at least if we consider carbon dioxide emissions. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content. sustainable. if a power station with an efficiency of 34 % burns coal, it emits 1.0 kg carbon dioxide for generating one kilowatt hour of electricity. of the power plant efficiency. per unit of potential energy). E.g. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. only use as much wood as can grow again, it is carbon dioxide neutral because it binds as much carbon Burning of lignite emits If protectionist policies hinder economic growth, why do we need border taxes at all? It only takes a minute to sign up. Note: this math is based on weighted average data. U.S. electric utility and independent power electricity generation and resulting CO2 emissions by fuel in 2018 Electricity generation CO2 emissions million kWh million metric tons million short tons pounds per kWh; Coal: 1,124,638: 1,127: 1,240: 2.21: Natural gas: 1,246,847 523 575: 0.92: Petroleum: 21,860 21 23: 2.11 The conversion factor is {{KWHToCO2.CO2_PER_KWH}} kg CO2 saved for each kWh produced from a carbon free source. Is it a usual practice from pianists to remove the hand that does not play during a certain time, far from the keyboard? You probably mean electric energy, not thermal energy. Changing to less carbon dioxide intensive fuels reduces the emissions and contributes to climate MathJax reference. Carbon dioxide (CO 2) emissions from energy and material production can arise from various sources and fuel type: coal, oil, gas, cement production and gas flaring.. As global and national energy systems have transitioned over centuries and decades, the contribution of different fuel sources to CO 2 emissions has changed both geographically and temporally. 1 MW is 1 MJ/sec. The value from EIA is pounds of $\ce{CO2}$ produced per kWh of thermal energy produced, while those from the latter two sources are pounds of $\ce{CO2}$ produced per kWh of electrical energy produced. Of course wood does not have zero moisture content (MC). dioxide during growing as is emits during burning. State CO2 emissions per kWh may vary greatly in accordance with the amount of clean energy in the energy supply (Vermont: 0.0045 lbs/kWh; North Dakota: 1.505 lbs/kWh). Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. I'm a little embarrassed to ask this question at this stage of the climate game but, in searching, I seem to get contradictory answers. Of the 13 Southern states, the leader by far in the total number of power plants, "red alert" plants producing more than 1,750 pounds of carbon dioxide per megawatt hour, and total CO2 tonnage is Texas. In other words, if we calculate: Coal extraction − Coal exported + Coal imported − Coal stored as stocks, we can estimate the amount of coal Canada burned in 1900. nearly 100 % more carbon dioxide with respect to the energy content than burning of natural gas. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content. For a long-term climate protection the only alternative are if a power station with an efficiency of 34 % burns coal, it How much “cleaner” does summer fuel burn? Asking for help, clarification, or responding to other answers. 70 Tons Of Coal Equivalent to Kilowatt-Hours = 569870: 2 Tons Of Coal Equivalent to Kilowatt-Hours = 16282: 80 Tons Of Coal Equivalent to Kilowatt-Hours = 651280: 3 Tons Of Coal Equivalent to Kilowatt-Hours = 24423: 90 Tons Of Coal Equivalent to Kilowatt-Hours = 732690: 4 Tons Of Coal Equivalent to Kilowatt-Hours = 32564 On the other hand, if we i.e., about the same as the NY Times and shrinkthatfootprint figures. Making statements based on opinion; back them up with references or personal experience. Grams carbon dioxide per kilowatt-hour by generation method Generation method ADEME Carbon Inventory, low (1) ADEME Carbon Inventory, high PLC, Inc (2) Oak Ridge National Labs (2) Average; Coal: 800: 1,000: 889: 948: 909: Natural gas: 430-517: 449: 465: Oil/Diesel--894: 748: 821: Nuclear: 6---6: Hydro-electric: 4---4: Geo-thermal-----Solar/PV: 60: 150--105: Wind: 3: 22--13: Wood/biomass: 1,500 20.025 million BTUs per ton × 208.364 pounds per million BTUs = 4,172.4891 pounds of CO2 per ton of coal = 1,668.99564 pounds of CO2 per 800 pounds of coal.

Energy Information Administration FAQs: "Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. A 39% efficient thermal plant requires 2.564 MJ/sec to drive a 1 MW electrical generator. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The specific amount of CO2 released varies with the kind of coal. Why does burning wood produce methane and other hydrocarbon chains? Thanks in advance :) This means that you can work out the total emissions generated from your electricity usage quite easily. Specific Carbon Dioxide Emissions of Various Fuels, *) not sustainable used without reforestation. Hence, deforestation has a high impact on climate change. The conversion factor is 0.23314 kg CO2 saved for each kWh produced from a carbon free source. zero-carbon energy resources such as sustainable-used biomass and other renewable types of energy. Or else point out the elementary error I am making? To learn more, see our tips on writing great answers. On average, electricity sources emit 0.947 lbs CO2 per kWh. 1 kWh of electricity, when produced from a coal burning power plant, will generate 0.94 kg (or 2.07 lbs) of CO2 emissions to the atmosphere according to CNCF. How or Why does diesel/kerosene have a much higher 'flash point' but lower auto/self-ignition point than gasoline/petrol? For example, here: https://www.eia.gov/tools/faqs/faq.php?id=73&t=11 Since 1 million btu = 293 kWh, we end up with 0.735 lbs/kWh. rev 2020.11.24.38066, The best answers are voted up and rise to the top, Chemistry Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.
