you're getting hung up thinking EV automatically means renewable energy. investing in EV's in no ways shifts the method of powering them. Investing in renewable energy does that.

You're technically correct on the surface. But people who get an EV are also probably more likely to get solar in their roof to charge that EV. I think your point though is that some states (I think Idaho?) power homes with fossil fuels, and buying an EV there will give the illusion of making a difference when it's really about the same.

I don't think most states are as bad as that though.

what? The US in general gets most of its electricity from fossil fuels by a huge margin.

The US is about 60/40 fossil vs non-fossil, with much better ratios in the places that the most EVs are being sold right now. This is also likely to greatly improve over the useful life of any new vehicle sold today.

On top of that, EVs are much more efficient at turning electricity into motion than fossil cars are in turning gasoline into motion, so you end up with a reduction in emissions even in fossil-fuel-heavy parts of the US.

As an EV owner, I don't have solar panels but I do have a 100% renewable electricity provider. I have a feeling a good portion of EV owners do something similar, either with solar, 100% renewable electricity, or both

So you’ve confirmed our worst suspicions about you. Good job.

lol. Weird hill to die on for you but whatever. Anyone with half a brain knows we have to transition to EVs so that renewables can power transportation. But I guess that concept is impossible for you to comprehend.

[-] blazera@kbin.social 1 points 1 year ago

We dont have the renewables to power transportation. Theyre fossil fuel powered.

[-] rusticus@lemm.ee 1 points 1 year ago

lol my EVs are 100% powered by renewables. You know that renewables are now cheaper than traditional fossil fuels, right? It’s not 1995 anymore honey.

[-] blazera@kbin.social 1 points 1 year ago

Great, so why are we still getting most of our power from fossil fuels?

[-] rusticus@lemm.ee 1 points 1 year ago

Are you asking why we haven’t switched to 100% renewables overnight unironically? It’s hilarious that you think your clueless points don’t make you look absolutely idiotic. Keep shoveling.

Congratulations, you just answered your own question.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
