Electric cars are touted as a solution for reducing emissions and improving the environmental impacts of transportation, but are electric cars actually any better for the environment than gasoline cars? This video looks to answer three main questions:
1) Doesn't EV battery production cause a lot of emissions?
2) Don't electric cars get their power from fossil fuels?
3) Isn't lithium mining terrible for the environment?

Hope everyone's having a great day! I put a ton of time into researching this video, and was surprised numerous times to learn about the differences in lifecycle emissions between gasoline cars and electric cars. It's a fascinating subject and I'm sure we can keep the discussion below civil! (That was a joke 😜). If you were curious about the battery video referenced towards the end, here's the link: a-head.net/id/video-1mXSMwZUiCU.html

This was phenomenal! You should consider writing a report or better yet a paper and publishing it in a peer-reviewed journal. DEwomen is great for most people. However, as an academic myself, I can see how having this review data in an academic format could be very helpful for a lot of people in academia.

+Luke W We have 5% in the grid because the grid is built and managed to support current demand. If we had more than 5% capacity in the grid then someone should answer why it is being run inefficiently. The grid has always grown in keeping with demand (I am not saying this was easy) - staying *just* ahead of it (anything else would be silly). And resources should be freed up as the oil network scales back. Grid growth might come from traditional sources (eg: growing supplier sizes in renewables) and some whacky ideas (of which V2G is just one of many). If all 31 million UK cars were replaced with EVs tomorrow the grid would probably have a big problem. But the very action of moving 31 million vehicles off the road will in itself take time.

+Awakened2Truth - Disciple of Jesus the Christ given a degraded battery can still have a value of over £1000, why on earth would anyone dump the battery. After a battery is beyond use for an EV, it can still be used for many years in a different environment e.g. home storage battery. I'd love to read any credible sources you have showing the "dumping of used batteries".

Are you sure you're an engineer? I thought you were going to talk about emissions that matter - you know actual poisonous ones. You only referenced CO2 which, as an engineer, you should know is not poisonous, is beneficial to the environment. Real scientists have proven that AGW is a myth. So why not do a video on real emissions?

That's all good said and done but you have to factor In the emissions for the battery in the gas car

He didn't factor in the emissions caused during the process of taking crude oil from its source and turning it into petrol/gasoline which ends up in oil refineries. Also the energy used during transportation of oil by thousands of supertankers across the globe or long pipelines. Plus its transportation to filling stations by truck. Or consider how electricity travels through cables from a power grid straight to an outlet to recharge vehicles.

Energy needed for mining iron ore, producing steel, welding steel and production of oil platform (1200 piece), energy for producing oil tankers, transport oil with tankers, energy needed for oil processing in refinery, producing tank truck, transport oil derivates, energy need for producing gas station...? Electric energy need 10 times less energy (with solar panels maybe 100 times) for producing and 10 les for enery transportatin. Battery is 100% recycling, oil burned in car is 0% recycling.

So question, and i'm sure its because i don't understand something. If a vehicle like in his example gets 17 miles per gallon, and a gallon weights about 8lbs. there 453 grams per pound. that would mean you burn 213 grams of fuel per mile. If thats the case how could you have 528 grams of CO2 per mile, when the weight of fuel being burned is only half of that, and thats assuming that 100% of the byproduct is CO2?

I just thought I'd point out that you don't mention the amount power used to refine the gas used by the fossil car, I haven't looked in to this but have heard the odd report that it creates more Co2 just to produce the gas than the EV vehicle causes in the production of electricity to travel the same mileage as you get from a gallon of gas ?.

As you said, no car is "green". 2 tons to transport 200lbs makes no sense, people don't care about being green, they want to virtue signal. E bikes on the other hand would make more sense for the average person. But sense having a nice car is more a status symbol than mere transportation, things wont change any time soon.

Don't forget to include the recycling of an electric car's battery when an electric car is old too. I'm sure there is a huge saving when recovering the lithium and other useful elements saving having to mine them from scratch. We are in the infancy of this battery recycling, but it will only get better with time.

Electric cars let affluent people who consume more energy than average people feel good about themselves for "saving the environment", whilst simultaneously providing yet another reason to arrogantly disparage working class people from the stage at the Academy Awards. Watch the masses of wealthy people turn in their perfectly good vehicles for new Teslas: cost of production be damned. I mean, South Park wrote the perfect episode about this very subject.

+Engineering ExplainedThanks for the response. Even if everyone bought a new super car, they wouldn't have to build entirely new infrastructure to support it (fuel stations, service stations, increased grid demand). I'm not saying EVs aren't the way of the future, I'm only saying you won't convince me that everyone immediately turning in their beaters for EVs is better for the environment. Strategically, it will probably help for future needs. In the short term, I'm not convinced that it's anything other than a fairly presumptuous and a classist talking point.

New tech is generally more expensive. You can pick up a used EV for under $10k with 4-5 years remaining on the battery warranty. The prices will continue to come down. Sure, a Model S is a rich person's vehicle, but there are more and more affordable EVs these days. Doesn't have to be this big economic divide (just like most of us don't own supercars).

It's purely a matter of how the electric energy is produced. Burning tons of coal or even usage of nuclear power plants (the latter barely leads to any CO2 emissions so is that even the best metric here?) can not be considered the more environmental solution
Martin Martin
Martin Martin Vor Stunde
Maybe this is your opinion but without having no respect for your work, there are some points which can be criticized or seen from another perspective. Although you pointed out some true facts the main statement that electricity is the cleaner solution (or the opposite) is still debatable. You even pointed out in the video that the main statement depends on the location where you charge your vehicle which is directly coupled to the question: "How is the electricity produced?". This and nothing else was my point and this is why in my opinion the whole question is a bit silly in the first place. Maybe I should have pointed this out more clearly in my comment. Electricity should be really seen as some form of energy transportation method. In contrast, fossil energy sources are not only a form of transporting energy but also the source of the energy, too. One can even take fuel/diesel and burn it to produce electricity. Please do no think that I have problems with electric cars. I think they are the future. But when it comes to the environmental aspects, I would say: "It depends...". However, even if you use the statistical approach here in form of the mean values (which is by no means the only approach here by the way) the metric is a bit problematic here, too. CO2 emissions are not the only relevant environmental factor. As I pointed out, nuclear power plants lead to nuclear waste which will be problematic for hundreds of years so we basically damage our environment for generations. One thing that I find problematic about all those "CO2 arguments" (in fact argumenting with CO2 emission is almost always silly; although most people do so) is that by reducing CO2 emission we basically do not gain anything in the long run as we are not tackling the root of the problem which is the setting free of all the CO2 which is bound in fossil energy sources (incredible amounts of CO2 by the way). Once the CO2 of those fossil energy sources is set free it is very hard to get it out of the atmosphere. The right thing to do would be to stop setting free all the CO2 in the fossil energy sources which can be achieved by increasing taxes on those energy sources over time until it is not profitable in comparison to "green energy" any more.

As this video demonstrates, it can, and obviously we should push for cleaner electricity production, but even in current form it's better than individual power plants in every vehicle. It's easy to make one, very big, very efficient power plant. Hard to do so in tiny form (cars) on a massive scale.

You also need to consider cost and production of engine oil/filters/belts/gearbox oil/exhaust systems/radiators and a ton of other stuff a gas car needs replaced during this period..one thing that electric cars will struggle with is winter driving and providing enough heat to keep passengers warm and screen clear without draining the battery in 10mins. For sure though we will all be driving electric cars very soon, battery technology is improving at a fast rate..the age of oil is numbered.

However, they need to address two issues on electric cars: First, the manufacturers need to improve the range per charge to something reasonable. I'd like around 500 km (310 miles) in normal driving per charge. This may finally happen when dry-electrode lithium-ion batteries reach mass production around 2020. Secondly, every electric car manufacturer needs to agree on a single, unified standard for electric car charging. This means standardized charging connectors worldwide and a uniform voltage standard worldwide for both AC and DC battery charging. The former is especially necessary since with a universal charging plug design, the fear of "range anxiety" drops quite a bit.

+Milan Swoboda I still think all the electric car manufacturers should convene a conference and agree on a single worldwide charging standard in terms of AC and DC voltages and charging connectors. That way, everyone will have an equal chance of finding a compatible charging station.

Your first point already has been complied with (Tesla M3 extended range) For your second point, Level 1 & 2 AC charging not much of a problem as they are easily adaptable in-between. Level 3 DC fast charging standards will likely still go through revisions since Voltages will go up as battery capacities increase but at this point there are not that many different Level 3 plug standards out there with CHAdeMO, SAE Combo CCS, Tesla HPWC and Tesla Supercharger. Tesla Level 3 charging being proprietary is a bit of a PITA but then again you also don't pull up to a Diesel pump with your gasoline vehicle and vice versa :)

There is another thing you should note: power plants don't shut down normally. They just don't connect to the grip or transfer the energy elsewhere. My point is that even though the coal power production is bad, you might as well use it to charge your car. You are actually storing the energy rather than let it go to waste.

The enviornmental impact of Li-Ion batteries for cars is a one-time event. Nearly all of them will be fully recycled so apart from initial effect, the consequence of making batteries is zero. Your first EV may have to run for a few months/years to break even but from then on its all gain and the next ones start out immediately bieng ahead.
