Are Electric Vehicles (EVs) "Green"

This is a presentation I did for my "Language and Communication: Presentation". For my research project I wanted to determine, based on pollution from the generation of electricity if an electric vehicle was any more environmentally friendly than a comparable gasoline engine.

With current power generation techniques in the US, it's not.

Please note, I am not against EVs at all, although I think the more practical way to go in the future is fuel-cell with an exhaust of pure water (H2O). We just don't have the infrastructure yet to support this.

This video, and the report it was based on is more about the inefficiencies and impracticalities of storing energy and the fact that 50% of commercial / public power generation is done by burning coal which produces the most greenhouse gasses of any source. That is all.

you are a moron!!... do you even think about how your clothes dryer is powered!?

[TheEdwardFrye]

@thecrism1 my clothes dryer uses 110v 15A alternating current to power the electronics, spin the drum, and blow the are; and it uses FIRE to heat the air. The fire is provided by burning compressed natural gas (CH4). What does this have to do with greenhouse gas emissions for power generation for the purpose of charging batteries?

You have no idea what you're talking about. This stuff has

been calculated by the best experts. They disagree. I admit

that EVs currently used use too much energy to travel, which

means we're going to have to travel less and transport supplies

less. And yes, the CO2 produced is more than it should be,

but the difference between electrical energy production using

fossil fuels and used in ICE's is wildly better, even including

transmission, which takes under a quarter of it.

[TheEdwardFrye]

The video was to make an arguable statement based on RESEARCH as part of a school project. The fact that you're attacking me personally speaks more for you.

Fact: 50% of power generation comes from burning coal

Fact: Charging an EV takes 26% more energy then available

Personally option: Mine more coal Drill for oil Use more CNG (Methane)

AND FIND A BETTER WAY

We have a long way to go

@TheEdwardFrye FACT: You're point that it takes 26% more energy than is available is false. If every car in America was converted to an EV and they were all plugged in at night (off-peak hours) our existing power supply would be sufficient. I find it laughable that you're bragging about "research" when you're clearly only regurgitating already bogus claims.

[TheEdwardFrye]

@Bromopar Part of the assignment was to use other people's research, not to perform experiments. The data that others have provided suggest that CO2 produced from using electricity from the grid in the US vs. burning gasoline is better by less than 2% per mile.

The question wasn't if we had enough power, the question is does it produce less greenhouse gas, the answer is lower than 2% less per mile when using power from the grid.

Most of the "research" I'm siting are EPA actual numbers

Also, electricity can be generated 100% green by means of solar, wind, tidal and hydroelectric generating. It is not currently but it will be increasingly in the future. Seems like you opened a can of worms with this presentation. I have to respectfully disagree with you.

I think you are missing the data on how much energy is consumed, both electrical and chemical (gas/diesel), in the drilling, pumping, refining and transportation of gasoline itself. Just think, to get the gas you have to find the oil (oil exploration). Then you have to extract the oil, then you have to transport the crude oil to the refinery, turn it into gas and ship it to the gas station. By the time all this is done it is definitely cheaper, more efficient and greener to run electric.

@TheEdwardFrye When the glaciers are gone there is

a question whether the three biggest rivers in Asia will be

dry much of the year, and rage out of control in monsoon.

When the temperature in Phoenix hits 165 one fine summer

day and the power fails, 50,000+ people will die. It already

makes it to 138 a day or two now. These heat storms won't

be constant, they'll be rare, but if they kill whole populations

the cool days won't matter. This is what we're looking at.

@TheEdwardFrye I've managed to pry it out of Fundies on

two occasions that they oppose renewables to hasten Armageddon.

Sounds stupid, I know, but they seemed quite serious. They don't SAY

it often because they are sensitive about being laughed at, but

global warming isn't a laughing matter. We can lose our food supply

when temperature zones for growing migrate too fast for plant

reseeding to keep up. Half the world will starve.
