how much co2 does coal produce per kwh

Energy Information Administration FAQs: "Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. The factor is based on the carbon emissions generated by the current UK power stations per kWh generated. The results of our analysis shows that wood is generally about the same or perhaps a bit lower in CO. 2. emissions on a dry basis (zero moisture content). 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. Burning of lignite emits 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. we see 215.4 lbs CO2 giving 1 million btu heat. Can someone be saved if they willingly live in sin? For a long-term climate protection the only alternative are How much carbon dioxide is produced when different fuels are burned? of the power plant efficiency. On average, electricity sources emit 0.947 lbs CO2 per kWh. If protectionist policies hinder economic growth, why do we need border taxes at all? Of course wood does not have zero moisture content (MC). Why does burning wood produce methane and other hydrocarbon chains? E.g. But at this site: http://shrinkthatfootprint.com/electricity-emissions-around-the-world How much CO2 is emitted by burning coal to produce 1 kWh of energy. E.g. zero-carbon energy resources such as sustainable-used biomass and other renewable types of energy. Thanks for contributing an answer to Chemistry Stack Exchange! Asking for help, clarification, or responding to other answers. But as it turns out neither does coal. This means that you can work out the total emissions generated from your electricity usage quite easily. 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. 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 Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. Did medieval people wear collars with a castellated hem? 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. sustainable. 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 If fuels are used for electricity generation, carbon dioxide emissions increase with the reciprocal These are very different numbers (too different for the problem to be type of coal, at least for eia vs NYT) and I have found other numbers at other sites. 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 Hence, deforestation has a high impact on climate change. Is there (or can there be) a general algorithm to solve Rubik's cubes of any dimension? How to migrate data from MacBook Pro to new iPad Air, How could I align the statements under a same theorem. Ask Question Asked 6 months ago. Viewed 40 times 0 $\begingroup$ 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. Or else point out the elementary error I am making? In our calculations, we convert kWh to kg of carbon released based on Greenhouse gas reporting: conversion factors from Department for Business, Energy and Industrial Strategy. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content. 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.. 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. Examples of back of envelope calculations leading to good intuition? On the other hand, if we Fuel is not equal to fuel - at least if we consider carbon dioxide emissions. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Making statements based on opinion; back them up with references or personal experience. Calculate the CO2 emission intensity (kg CO2 emitted/kWh delivered).Assume complete combustion where all the available carbon in the fuel is converted to carbon dioxide gas. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content. Changing to less carbon dioxide intensive fuels reduces the emissions and contributes to climate Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. per unit of potential energy). Can anyone point me to a site that I can trust for this number and others like it (related to energy production)? Active 6 months ago. Even natural fuels such as wood or peat have high specific emissions, if they are not used protection in the short-term. Since 1 million btu = 293 kWh, we end up with 0.735 lbs/kWh. Step 3: converting energy produced to CO 2 emissions. nearly 100 % more carbon dioxide with respect to the energy content than burning of natural gas. Since the thermal efficiency of coal-fired plants is ~37% (~37% of the coal's thermal energy is converted to electrical energy), converting the EIA figure to pounds of $\ce{CO2}$ produced per kWh of electrical energy produced gives us: $$ 0.735 \frac{\text{lbs }\ce{CO2}}{\text{kWh thermal energy}} x \frac{\text{1 kWh thermal energy}}{\text{0.37 kWh electrical energy }} = 1.99 \frac{\text{lbs }\ce{CO2}}{\text{kWh electrical energy}}, $$. A 39% efficient thermal plant requires 2.564 MJ/sec to drive a 1 MW electrical generator. 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). It only takes a minute to sign up. The specific amount of CO2 released varies with the kind of coal. The conversion factor is 0.23314 kg CO2 saved for each kWh produced from a carbon free source. Convert x y coordinates (EPSG 102002, GRS 80) to latitude (EPSG 4326 WGS84), How to look back on 10 years of photography. we see 1 kg/kWh = 2.2 lbs/kWh, New York times https://www.nytimes.com/2007/11/07/business/businessspecial3/07carbon.html This means that you can work out the total emissions generated from your electricity usage quite easily. Changing to less carbon dioxide intensive fuels reduces the emissions and contributes to climate protection in the short-term. Use MathJax to format equations.
