Just switching transportation away from fossil fuels would not be enough to stop climate change. Electric vehicles powered by fossil fuel power plants are still more efficient than ICE engines burning fossil fuels, mostly because larger engines are more efficient and the centralization allows for better maintenance. A better law would be to mandate that a certain percent of power must be replaced by renewables each year.

Why can't they be powered by nuclear plants or hydro? Also, the image is stupid because the generators at even coal plants are cleaner and more efficient than any mass produced ICE vehicle.

i remember just a few years ago when trump said something about clean coal tech and all of the glowing greenies and their stooges were screeching madly about how "theres no such thing as clean coal"
now that the narrative has changed the same folks are screeching about how clean coal plants are.

>>14723756
Coal is only a "clean" power source when you compare it to worse power sources like car engines. Your reading comprehension is shit.

>>14723756
Liberals are still against cleal coal.

>>14723756
>theres no such thing as clean coal
That's still true. There just is coal. And while it's shit, it's less shit than that 10% efficiently combustion engine in your car. In the long run, EVs should be powered by renewables, no question. The Facebook boomer who wrote OP's picture probably doesn't know about hydropower and geothermal energy.

>>14723776
the carbon footprint of mining lithium to make a tesla is on par with the carbon footprint of a standard light truck with 100,000 miles on it, add the coal to power the tesla on top of that.

>>14723638
>Why can't they be powered by nuclear plants or hydro?
Because green shills should be limited to the energy sources they shill for the hardest.

>>14723620
>Would this stop climate change or should we continue to use fossil fuels to power electric cars?

Climate change = hoax by the rich elite. They want YOU to give up transportation since transportation is what elevated the lower class and created the large middle class.

The rich want the 95%(those who aren't part of the elite or their "elected" minions) poor. Yes that means you.

>>14723620
You could put all of the west in electric cars. So long as China, India, Bangladesh etc are pumping out co2 and no effort is made to force environmental laws on them (but us for some reason despite having them quite low) global warming, as claimed by the ipcc, is innevitible. Nevermind when Africa begins to fully industrialise

Guys. I just found out that water is a greenhouse gas. And there is a freakin' LOT OF IT

>>14723914
>Climate change = hoax by the rich elite.
The fact they're scam artists doesn't mean that the underlying science is bullshit. Quacks selling miracle cancer cures don't discredit the existence of cancer.

>>14723987
yeah duude, all this warming is just because the seas appeared suddenly in the '70s

I hope climate change is real.

>More arable land when the ice caps melt
>Coastal cities destroyed, liberals forced to migrate and integrate into other areas, likely will all be impoverished since giant loss of equity
>no more 'don't use petrol garbage' because ice is all gone anyway
>shitskins near tropics btfo
>shitskins try and immigrate, but not enough land or resources to support them so their boats get sunk

Also lots more room in Russia and Canada, and now we can visit Antarctica to check for Nazi UFOs

>>14723914
This is why /ourguy/ Musk is so based. With electric cars we can drive forever without running out of oil.

>>14723620
Why stop there? Why not make it so electric cars cannot be made using fossil fuels. Starting from extracting the raw materials. This means no plastic since plastic is petroleum, no oil to lubricate the electric motor bearings, no steel since steel requires coke, and no synthetic rubber for tires. Since we can't use ships and planes, all resources must be sourced locally, refined locally, with the products manufactured locally in factories that aren't made from steel or concrete. We can't use trucks or diesel-electric trains either so all goods must be transported by horse and carriage. Actually horses emit carbon dioxide so we would just use humans pushing carts. And humans emit carbon dioxide too so actually none of this would work and we should all just kill ourselves.

>>14723838
And it yet it's still less than the average ICE vehicle.

While this would be nice for local jobs this isn't needed; we can already transport people and goods without the need for fossil fuels.

Seethe more

>>14724254
True but the technology already exists, now it only needs investments.

Also this guy >>14724269 isn't me, just some attention whore jumping into the conversation.

>>14724272
You can also seethe more

>>14723620
Here's the elephant.
Lets assume you could replace every car in existence with an electric car.
But there's one problem. There aren't enough rare metals in the world to make batteries for all of them.
Even if you only replace 20% of all cars with electric, the rare metal resources would be exhausted within a few decades. Recycling the metals will extend it for another few years, but at that point it becomes exorbitantly expensive.

Here is what no is is telling you. Fossil cars will be phased out, but we will not see everyone driving electric cars instead. Electric cars will only be for the very wealthy and for the Government services ( police, fire, medical ). The rest of you will be walking, cycling or taking buses.

>>14724269
>>14724277
Scientists are working round the clock to see if it's even possible to seethe more than you

>>14724332

Transition to clean electricity generation and electrification of transport are two different technologies that are both required for clean transport. They do not need to be completed at the same time or in a specific order, it's good that they are developing in parallel.

There's an alternate universe where clean electricity happened first but OP is no more or less intelligent, and in that reality their retarded post is pointing out the "hypocrisy" of closing all the coal, oil, and gas power stations before everyone has stopped using gasoline powered vehicles.

China is a EV tempest. Right now Tesla is the big one but many big EV companies are going to come put of China. Another problem is Africa cause there will be so many people it sounds terrifying

>>14725964
Wind power causes the greenhouse effect, greenhouses function by restricting convective motion in the local atmosphere, same as windmills do. CO2 does not restrict convective activity at all.

>>14725964
That's significantly less oil than New York uses now.

>>14725980
The greenhouse effect has nothing to do with convection.

>>14726007
you're ignorant of thermodynamics if you think that convection is a non factor in atmospheric dynamics

>>14726736
Atmospheric dynamics have nothing to do with the greenhouse effect. It's literally just the energy budget of the earth. Greenhouse gases cause the earth to retain more energy.

>>14725964
That image was shown to be false in the last renewable energy thread. And it is still false now.
