How much carbon dioxide does the United State and the World emit each year from energy sources?
The U.S. Energy Information Administration estimates that in 2019, the United States emitted 5.1 billion metric tons of energy-related carbon dioxide, while the global emissions of energy-related carbon dioxide totaled 33.1 billion metric tons.
Picturing a ton of CO2 “1 Ton CO2 Balloon”
- ” .. The average American car emits about 7 tons of CO2 in a year;
- the average American family, about 24 tons;
- the United States as a whole, over seven billion tons;
- and worldwide, almost 30 billion tons. “
.. CO2 is made up of atoms, and atoms have mass, and with gravity mass has weight. ..
Picture a football field, and then imagine a round balloon with one end lined up on the goal line and the other on the 10 yards line –
that is a balloon with a diameter of 10 yards. If that balloon were filled with CO2, it would weigh about 1 ton;
it would be a 1-ton CO2 balloon.
In 2006 an American family emitted the equivalent of 24 CO2 balloons by powering their home, driving their cars, and flying. In total, Americans were responsible for more than seven billion CO2 balloons in 2006. Lined up end to end they would circle the earth 1,600 times, and the number grows each year. Isn’t it about time we start taking the CO2 out of some of those balloons? “
How much tailpipe CO2 is created from burning one gallon of fuel:
9 KG or 20 Pounds of CO2 / 1 Gallon of fuel
- CO2 Emissions from gasoline: 8,887 grams CO2/ gallon
- CO2 Emissions from diesel: 10,180 grams CO2/ gallon
How much tailpipe CO2 is emitted from driving one mile: about 0.9 Pound / 1 mile
The average passenger vehicle emits about 404 grams of CO2 per mile
Greenhouse gas (GHG) emissions from transportation account for about 29 percent of total U.S. greenhouse gas emissions
…. making it the largest contributor of U.S. GHG emissions.
Between 1990 and 2019, GHG emissions in the transportation sector increased more in absolute terms than in any other sector.
What are the average annual carbon dioxide (CO2) emissions of a typical (passenger) vehicle?
(When using the assumptions below) A typical (passenger) vehicle emits about 4.6 metric tons of carbon dioxide per year.
This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.
Based on Global Emissions of 2010
CO2 PRODUCTION BY ELECTRIC VEHICLES (EFFECTIVELY)
from data on Electric Power Industry
33% of CO2 from tailpipe of traditional vehicles
Energy Consumption by Electric Vehicles:
0.346 kWh per mile (kilowatt-hours per mile)
- On average it takes 34.6 kWh to travel 100 miles (34.6 kWh/100 miles)
How much carbon dioxide is produced per kilowatt hour of U.S. electricity generation?
- 0.86 pounds of CO2 emissions per 1 kWh.
- 4.01 Trillion kWh ==> 1.55 B metric tons Co2 as byproduct;
- 2.59 Trillion kWh ==> 1.0 B metric tons CO2 as byproduct;
- 2.6 kWh ==> 1KG CO2 as byproduct;
- 1 kWh ==> 0.39 KG CO2 = 0.86 Pounds CO2
” In 2020, total U.S. electricity generation by the electric power industry of 4.01 trillion kilowatt hours (kWh) from all energy sources resulted in the emission of 1.55 billion metric tons—1.71 billion short tons—of carbon dioxide (CO2). This equaled about 0.85 pounds of CO2 emissions per kWh. “
EVs Also Cause CO2 (as a byproduct of Electricity Generation of today)
Our calculations CO2 per mile emitted by traditional passenger vehicle: 0.9 Pounds /mile
8,887 grams of CO2 per gallon; 22 miles per gallon;
8,887 / 22 = 404 (grams of CO2 per mile) = 0.404 x 2.2 (pounds of CO2 / mile) = 0.888 (0.9) Pounds of CO2 / mile
Our calculations of CO2 used for EVs per mile: 0.297 pounds of CO2/mile
(as a by-product of electricity generation)
0.86 pounds of CO2/1kWh x 0.346 kWh/mile = 0.297 pounds of CO2/mile
EV v.s. traditional Internal Combustion Engine (ICE) automobile (effective) CO2 exhaust is 33%
0.297 pounds / 0.9 pounds = 33%
