EV Emissions Debate

The cluster focuses on debates comparing lifecycle emissions and carbon footprints of electric vehicles (EVs) versus internal combustion engine (ICE) vehicles, including whether EVs reduce pollution even when charged from coal-heavy grids.

Not sure about that. Use emissions is the majorityhttps://www.visualcapitalist.com/life-cycle-emissions-evs-vs...

Keep in mind that the ~1.5B cars + trucks in the entire world combine for only ~10% of worldwide greenhouse gas emissions. Also, if your electricity is made by coal power plants there's no point using EV.

Am I right in believing an EV has a lower carbon output per unit distance than an ICE vehicle even if charged by thermal coal power?

This post highlights some persistent myths surrounding electric vehicles:1) Even if you're using electricity derived 100% from burning coal, you're still causing less pollution than most gas-powered cars. This is because power plants are hugely, massively more efficient than internal combustion engines, and because it's much easier to filter pollution out of one big smokestack than thousands of small ones. Furthermore, even just refining oil into gasoline takes almost as

This article addresses your questions:https://www.carbonbrief.org/factcheck-how-electric-vehicles-...Check out the "lifecycle greenhouse gas emissions" figures. It's really interesting in how it shows how different the total emissions are depending on which country you charge your electric car in. Also, depending on which electr

Multiple studies have shown that, even if an EV is charged from a power grid powered 100% by coal, it still produces about the same CO2 as a 50mpg ICE vehicle. Very few grids are that dirty and contain a mix of cleaner sources like natural gas, nuclear, wind, solar, and hydro. Each cleaner source you add reduce the CO2 output due to that EV. On a typical grid, it only takes about 12K miles to offset the additional energy needed to manufacture that EV.

It seems there's an assumption in the article and in the comments here that "more EVs == net positive impact on pollution / greenhouse gases". This is not obvious at all. It depends on the way you produce electricity, and when 75% of it comes from coal, you may end up worsening the problem. This could be a smart move if the automobile market had a bigger inertia than the energy one, but I doubt it's the case...

That is not correct. EVs are so much more efficient than ICE vehicles they are still a net win even when powered with "dirty" electricity.https://www.forbes.com/sites/mikescott/2020/03/30/yes-electr...

I'm planning on purchasing an electric car when I replace the car I drive now. After looking into it, I was disappointed to find out that all of us switching to a battery electric cars won't make that big a dent in global greenhouse gas emissions. Cars are responsible for only around 15% of these global GHG emissions (see [1], [2]).Furthermore, a battery electric vehicle produces approximately 180 of grams of CO2 per km (counting life cycle emissions). This is sometimes better than

Are you sure it will reduce the pollution (genuine question)? The cars will stop polluting directly but the electricity producers will start producing much more electricity (which is much more pollution) to feed the cars. So, which of these two pollutions is better - nuclear waste/pollution or co2?
