JustFacts
This quite literally is a just a place to keep raw facts and useful info.
Miles:
Miles driven per year on US roads: 3 trillion
Miles per KWh of average modern EV: 4 combined highway and city, 5 city
Miles driven per year per driver: 14,300
Miles driven per day per driver: 39
90% of the US population drives less than 40 miles per day
Force vs speed: Pounds = 42.30 ‐ 0.0212 * mph + 0.01691 * mph * mph.
CO2:
Lbs CO2 emitted for power generation at 200 grams CO2 per KWh is 2.2 lbs for 20 miles of driving. If 300 grams per KWh then 3.3 lbs for 20 miles. 400, 4.4 lbs, etc
Lbs CO2 emitted from well to your cars tank for a gallon of gas: 3-7 lbs (stanford study)
Lbs CO2 emitted from engine when it uses 1 gallon of gas: 20 lbs
For people confused about the weight:
a gallon of gasoline is composed of carbon and hydrogen and weighs about 6.3 pounds,
When gasoline burns, the carbon and hydrogen separate. The hydrogen combines with oxygen to form water (H2O), and carbon combines with oxygen to form carbon dioxide (CO2).
A carbon atom has a weight of 12, and each oxygen atom has a weight of 16, giving each single molecule of CO2 an atomic weight of 44 (12 from carbon and 32 from oxygen).
Therefore, to calculate the amount of CO2 produced from a gallon of gasoline, the weight of the carbon in the gasoline is multiplied by 44/12 or 3.7.
Since gasoline is about 87% carbon and 13% hydrogen by weight, the carbon in a gallon of gasoline weighs 5.5 pounds (6.3 lbs. x .87).
We can then multiply the weight of the carbon (5.5 pounds) by 3.7, which equals 20 pounds of CO2!
Coal Power Plant: emission 2 lbs CO2 per kwh electricity
Natural Gas Plant: emission 1 lb 3 oz CO2 per kwh electricity
CO2 passes normal sunlight without blocking it. However that sunlight heats the earth and is reflected back into space as infrared radiation which CO2 in the atmosphere basically gets excited about and holds onto that energy. Hence a greenhouse effect where light gets in and heat can't get back out. Has absolutely nothing to do with the fact that greenhouses use CO2 to aid plant growth...that is just how plants grow.
