I like the visual representation, but I would have preferred some statistics, as that was his original claim to research. The only statistic mentioned is a green threshold at 100000km. This is an incredibly important topic if this is accurate information, and I wanted more depth than 1:30

Primary source of electricity generation should be clean..

Several Wall Street VC’s have told me the same……

The latest study on global comparison of lifecycle GHG emission of electric vehicles and combustion engines debunks most of the arguments asserting that electric vehicles pollute more than diesel vehicles. The study was published by International Council on Clean Transportation in 2021 and considers electricity mix in different countries such as USA, China, India and Europe. Specifically for India, Battery Electric cars are 19%-34% lower in lifetime emissions compared to combustion vehicles. I encourage anyone interested in this topic to read it.

How about using less cars and more public transport for increasing efficiency?

ahh but there was no mention of the environmental impact of extracting, transporting and refining diesel........it is often omitted from representations like this. One study approximated it to roughly an additional 30% on top of the emissions you produce directly from the vehicle. Having worked in the oil industry on the shipping side - I would be surprised if it's any less than that. The differences in environmental impact around the world for running electric cars are enormous depending on the primary source of energy for the generation of energy. With a shift to more renewables or nuclear power - the cross-over point of EV's being lower emissions than their ICE counterparts reduces drastically. For example it's now estimated that the initial 'debt' of producing a new EV is 'paid off' in Norway after roughly a year........but then with over 95% of all energy coming from hydro electric, Norway is pretty unique. It's not always about 'overall environmental impact' either. In some cases, the biggest benefit is to the local environment and that can have a lot of positive effects (as he mentioned the smog problems). However, going full EV is just not viable unless there is a substantial investment in the entire infrastructure to support it - and that doesn't happen unless there is full agreement at the highest levels.....half measures just won't cut it.

What about production of diesel and transportation of diesel to fuel stations.

It’s is true that from a CO2 emissions perspective, if an economy is based on thermal coal EVs take a lot longer to get to net zero against ICEVs. In Europe the only example is Poland, and that is over a 50,000km lifetime. India should stop relying on thermal, oil and gas power generation and these “statistics” (or lack of) make sense. Also you are ignoring particulate matter emissions. India should be particularly concerned with this. No particulate emissions from EVs and if you insist on generating thermal power at least these have better filters than your cars.

Very convenient and partly self serving argument. In case of manufacture of EVs he is tracing back to the mining of minerals and production of batteries. Why not add the polluting factor of every litre of diesel the ICE car will consume, not just in terms of the cars emissions but also in the process of drilling the crude oil, its refinement and transportation? This will bring out an apples-to-apples comparison. By the way, is it a coincidence that an oil company is sponsoring this talk?

You didn't give any numbers and I suspect that your numbers are wrong or dated, but also they vary greatly based on your electricity mix. India may have one set of electric production, US, EU (and each country there), China, etc.. different. Even if I take your numbers as fact (which I don't without a lot of background info that was not given), the cars last longer than 100K miles (much less 100K kilometers). In the EU and US the batteries are warrantied that long and the modern ones are lasting over 300K miles (500K kilometers) on average. And yes we do know this because we have commercial batteries that have lasted that long. Second point even if with your current grid the benefits are not going to be realized for 100K kilometers (which again, they will last much longer than that, even the battery), decoupling the transportation from the grid is a good idea. If people keep driving diesel they are tied to burning fossil fuels for the life of those vehicles. If they drive an EV as the grid gets cleaner the EV gets greener. Third, coal (which is what you are using for a comparison), is the fastest fossil fuel to be removed from the worlds electricity mix. It is rapidly being replaced by either renewables or natural gas (not diesel in most places) simple because of cost. Natural gas being the worst option there, is much cleaner burning than diesel, and more efficient in conversion to electricity. My point is that even if what you say is true people should not be holding off on buying an EV and buy diesel cars for the reasons you give. Even with the current battery technology it is better for the environment to buy an EV than it is to buy diesel. Cost too for the US and EU at least. I don't know what EV pricing is where you did this study. In the US the TCO for an EV has been lower than an ICE car since 2018, they tend to break even between 2-4 years now. Given that the loans are 5 years on most cars you will simply pay less for an EV than an equivalent ICE car. People that choose not to buy an EV for cost are not doing the math. There are plenty of reasons not to buy and EV for lifestyle fit, but the cost is not a realistic reason to do it. I should clarify, that is new EV vs. a choice of buying a new ICE car. If you are on the used market it is infinitely more complex.

You lost me as soon as you blamed 'climate change' for tsunamis!

If it is so, why aren't EVs banned yet??

I don't know how he got his number but 100,000 km is that much. He is making it seem like some far off thing

I feel bad about the presenter because of his lack of knowledge in modern EVs. He didn't consider few facts knowingly or unknowingly, 1. Modern Car batteries do not always depend on rare earth metals. They use Na, Li, Fe, which are easy to get through less polluted ways. 2. Modern car batteries have long life. They come with 8 years warranty & last more than 10 years. Thereafter they do not go to dumps & used in battery storages to power houses or supplement national grids. They are used for min. 15 years. 3. Many countries where EV sales are high, do not use diesel or coal to generate electricity. They have nuclear power or large portion of alternative green energy such as solar or wind power. 4. Countries like India can easily encourage EV buyers to fix solar panels on top of their roofs to make their cars really green. India gets plenty of sun year around. 5. A small car dispose min. 100+ liters of burnt engine oil for every 100,000 kilometer. In countries such as India, those oils are not recycled. Either they leaked in to rivers or burnt as substitute in industrial furnaces. This presenter avoid this fact entirely. 6. EVs are much simpler machines than ICE. They have the motor & the battery which are seal type. There are many other parts of diesel/petrol cars (in engine, power transmission & cooling system) such as rubber valves, bushes, grease, etc. which pollute the environment in its production & disposal. 7. This presenter does not consider that efficiency of energy conversation in power plat is much higher than automobiles. This highlights a problem in Educated Indians & their business community. They mostly consider India as the world & failed to look beyond boundaries of India. They are reluctant to adopt foreign knowledge/experience & most of the time try to develop their own. This make them lagging generations behind other courtiers in technology. If they look & get inspired by China, Europe & Amerika, this presentation would be much more helpful for better India & world.

Very credible😂

Get your facts right you are so wrong

The most uneducated tedx talk so far.
