Electric cars pollute more than diesels – page 19 – chevy ss forum electricity lab activities


The carbon assumption for production being equal-there is no mention if that takes into account use of recycled materials, as part of the feed stream INTO the car, or as part of the waste stream OUT OF the car. e seva power bill payment Meaning, there may be a difference in the net carbon impact when recycling is included in the equation and since the whole point is a holistic approach to the environment, it should be included.

Giving the combustion engine the benefit of the doubt on the battery CO2 impact also assumes that there is nothing additional needed to support the battery. In reality, having an appropriate charging station at a home or business could be an issue. If the existing circuit isn’t appropriately sized, then additional wiring and circuitry may be needed. This is personal OE from one of our Senior Management having a Tesla. 9gag instagram We had to add a new distribution panel so the Tesla could be charged without turning off power to part of the admin building. gas national average This building was built in the 1990s-imagine the impact for areas built decades before.

For the average commuting time and distance; it would be interesting to have a study that breaks down the average commute distance by vehicle type. The folks at work with the longest commute bought smaller ICEs or EVs; the larger ICEs live 2-10 miles from the plant. So the averages might vary across populations by region as well. gas in oil There was no discussion or source that would help with this point.

By state, the states that have low CO2 emissions due to low emission grid inputs are in danger of losing that status-examples of New York and Illinois. Anyone else notice that CA has a 10% higher average for Natural Gas than the Nation? That would be the additional support needed for Wind and Solar. gas oil ratio for weed eater Again, should be part of the mix, but here is the data that shows what the end result looks like for the grid.

Interesting on the EVs in different states; how much is weather factored into performance? In this link ( https://elbil.no/the-biggest-electri…nderland-ever/) EVs were tested in cold weather, but the test used a charge to 80% for time and cost; but what does that do to the battery life during ownership and how does that impact the CO2 output? Decreased battery life=higher CO2 impact.

"Batteries are going to last longer than a couple years because manufactures are providing 8 year/100K mile warranties with them." So, no accounting for the batteries that suffer infant mortality and are replaced under warranty? Statistically not a high number, hence why the warranty lasts that long, but in the fairness of correct CO2 accounting, it matters.

So, for the states where a plug-in is the more ‘green’ car, what is the main power source? Everywhere that is blue or purple has nuclear plants supplying the grid. It’s hard to make the argument without that data point. (Also FYI; Az provides ‘green’ power to CA, so that swatch does make sense if you know that. la gas prices now Yay PVNS.) Click around a few states-keep in mind which states are neighbors to the most populous states-there’s usually more plants outside the dense population areas, which may mean power is provided from a different state.

It may be a myth to generalize the an EV is worse for the environment, and it is still a necessary part of the decision and conversation to be cognizant of the grid source where the EV will be charged. Knowing that in many large cities where power plants are located outside city limits, maybe the better environmental option is public transportation and minimal use of car altogether. Cities like historic Dubrovnik (Croatia) have strict control over cars allowed inside city limits-which would certainly limit the amount of CO2 produced.

• The emissions benefits of workplace charging increase as the carbon intensity of the grid is reduced. Sensitivity analysis indicates that the Workplace charging scenario continues to result in the least emissions, even when the carbon intensity of the grid varies substantially. However, the larger number of electric miles afforded by workplace charging can result in higher total emissions than other charging scenarios on high carbon grids.
