In the U.S.A., what would happen if everybody started driving electric cars?
About 9 million fewer barrels of oil would be used each day.
If you have a car that gets 28MPG and drive it 10k miles per year, you would use just over 300 gallons of gas and produce 5.6k pounds of CO2.
My Ford Focus Electric gets about 4 miles to a kWh. The worst coal produces 2.17 pounds of CO2 per kWh. So 10k miles per year produces 5.4k pounds of CO2.
So whats the big deal? Looks like a wash, right? No. It takes about 6kWh to distill one gallon of gas. So burning the coal to produce one gallon of gas produces about 13 pounds of CO2. Multiply that by 300 gallons of gas and you get another 3.9k of CO2 a year just making the 300 gallons of gas.
So by eliminating the gas engine and the process of refining oil into gas, you eliminate a duplication of effort and excess CO2 production.
You also eliminate the extra toxic pollution from burning gas, and the production of gas produces all kinds of toxic substances on top of the toxins burning coal produces.
Produce the electricity with natural gas and you get less CO2, but, there are still many bad side effects in the production of natural gas. Fracking uses lots of clean water and turns it into toxic water.
Produce the electricity with solar or wind and get rid of all the by-products of combustion of fossil fuels. Then the only pollution is from making the solar panels or generators.
Lets also take a look at how gasoline gets to market.
Oil is extracted from the earth and transported long distances by ship or pipeline. By ship requires burning more fuel to move the oil over long distances.
Once the oil is refined, it gets put on a tanker or pipeline again, to get to it’s next destination. More fuel is burned for transportation. And all along the way there are many opportunities for leaks and spills. That doesn’t even include the potential leaks, spills and disasters at the point of extraction. The Gulf of Mexico, Exxon Valdez, waste from tar sands piling up on the south side of Chicago. The list goes on and on.
Most Americans have electricity in their home. Most Americans drive less than 50 miles per day. All they would need to do is plug in their cars at home each night like they plug in their Smartphones. You don’t need to add a huge new infrastructure like you would for hydrogen.
If every car in the USA were electric we would use 374 million less gallons of gas per day. That’s 811 million less pounds of CO2. Wait, we figured that the CO2 burned in gas was close to the same amount used to produce the electricity needed by burning coal. OK, that’s a wash.
But, if it takes 6kWh to produce 1 gallon of gas and 2.17 pounds of CO2 is produced per kWh then the amount of CO2 produced is actually 6 times 2.17 or 13 pounds of CO2 produced or 13 times 374 million gallons of gas. Thats 4,862,000,000 more pounds per year of CO2 than our hypothetical all EV Nation needs. That’s a massive difference.
What else could go along with that. No oil changes. No air filters. No spark plugs. Fewer brake pads. That’s just a few benefits. No pollution controls needed on an electric car. No emissions inspections. I’m sure you could find a few more.
So lets sum it up.
Air polution, less.
Water pollution, less.
Noise pollution, less.
Oil Spills, less.
Carbon Monoxide deaths, less.
Burn Victims, less.
Lower Hospital Costs.
Fewer wars? Probably not?
Where’s the down side? Fewer gas stations? High School kids can’t put sugar in the gas tank of their ex-girlfriend?
Next year almost every carmaker has at least one if not more hybrids that can actually run on electric 90% of the time.
If you can afford a car that is partly or fully electric you should buy one.
It’s time to actually conserve the resources we have.
It’s time to stop polluting our air and water.
This is not a political issue anymore. It is a financial issue. It’s cheaper to burn coal to make electricity to drive a car than to make fuel to drive a car.
It’s cheaper to drive an electric car than pay for hospital costs for people with diseases related to air pollution or water pollution.
If you want make solar panels and wind power the political issue, go for it. It is still 3 times the cost of coal if you don’t price in the pollution and medical costs caused by coal. We are maybe 3-5 years away from cost parity with coal.
We are probably 3-5 years away from your next car being electric as well.
Maybe it’s time for electric companies to embrace people putting solar on their roofs instead of fighting it. But that’s a subject for another post.
