More emissions cheating
To paraphrase a song from my youth -- "Will it ever end?"
https://www.epa.gov/newsreleases/epa...-labels-number The worst mileage cheating seems to be Ford hybrids and Kia and Hyundai vehicles. The rest seems pretty immaterial to me. But I wonder about the pollution issues. How much additional pollution did the cars spew into the air? I didn't see any results on that. |

Eh, this would be accurate depending on where you live. Some places use Hydro for power instead of burning coal.

64% of global electricity produced by combusting hydrocarbons in 2018.
https://www.iea.org/geco/electricity/ Reading the iea summary on electricity in the link, electric vehicles are not mentioned once. |

The equivalent of an electric vehicle mpg is about 90mpg that taken into account everything. If that's accurate then, then electric vehicles should be more efficient, but the problem is I don't know if they take into account EVERYTHING. How about the cost of mining Lithium? How about the cost of recycling old Li-on batteries? Another thing is the amount of Lithium raw materials on the entire earth is limited and even more so than oil. So if everybody were to drive an electric car, they may not be enough lithium raw materials for everybody.
I hope they look into fuel cell. Although you also need battery to store the energy generated from fuel cell but the amount of batteries here is not as much as a pure battery-powered car. |

It's actually more efficient to burn hydrocarbons at a plant, especially a gas-turbine, and transmit the electricity to your charger, than to burn gas in your own individual combustion engine.

True, but reducing our dependence on oil in general, which would include foreign oil, would be a huge benefit, plus, that means more for the military to power their machines and train.

I understand electric cars are more efficient than ICE cars overall. My point is the amount of Lithium that can be extracted is limited just like oil so eventually you will run into supply issues. |

Not here where electricity is over 30 cents a KW hour and is randomly turned off for "fire risk".

Cost equivalent MPG converts electrical energy usage of EVs and PHEVs to its equivalent in gasoline based on cost. For example, if gas price is $4.00/gallon, an electric car that could go 100 miles on $4.00 worth of electricity would have cost equivalent MPG of 100.

US average is 14 cents per kWh?

Based on US average of $2.64/gal. Gasoline is 8 cents per kilowatt hour. Average US electrical price is 13.7 cents per kilowatt hour. Maybe we need to spend R&D on increasing the efficiency of burning gasoline...

I just did a real rough CO2 per kWh calculation comparing my local utility emissions to an X3. Far from precise but it tells me that plug power (electricity from a wall socket) generates approx an order of magnitude less CO2/kWh than running a modern IC engine.
What does that mean, and who cares? Good questions. Last edited by chassis; 10-12-2019 at 12:35 PM.. |
