>I will ask again did anyone performed LCA on solar, wind turbine vs natural gas, coal, nuclear?

https://www.nrel.gov/docs/fy13osti/56487.pdf

I will state again, you didn't take 30 seconds to google.

This is just solar, but I'm sure you can type LCA wind, tidal, geothermal, nuclear, ect.

Quick note, the summation of the report (which is itself a summation of HUNDREDS of LCAs) is that coal produces 25 times the CO2 emissions per kWh.

Quick maths for ya, if a solar plant ends up producing 100g of CO2, coal will produce 2500g of CO2 to produce the same amount of energy.

Welcome to the present, we've been facing this problem for decades and have spend billions of dollars on R&D. The questions involved in LCA are essential and we've been attempting to address them at every turn.

I'm confused why you decided to posit the same question again of "did they look at LCA," when I already answered in the affirmative, especially considering verification of my affirmation would take you less time then you spend writing a response.

Stop asking "if people are asking the hard questions" and start trying to see if people have found the answers yet. If during your research you find an unasked question of merit, that is a fantastic time to bring it to others attention. We live in the information age and there are 7 billion of us, if you're asking questions but haven't checked to see if there are answers you either don't want to know the answers, want someone else to hit the search bar, or just want to disagree without actually taking a stand

> The problem with renewables are that they only last 20 years

I'm sorry, what? Do you think replacing solar panels / wind turbines is worse that mining / fracking / drilling? Ignoring the CO2 going into moving massive amounts of earth / setting up offshore oil rigs for a second, a solar farm has never leaked and poisoned the gulf of mexico. An unpainted wind turbine might kill some birds, but it's never leaked into multiple township's drinking water. Your assertion that if we look the true life cycle of renewables it might have more greenhouse gas emissions than mining and burning greenhouse gasses is confusing at best.

>Just keep in mind solar is only good for a couple of hours

Even if solar was the only thing being used you're still drastically reducing the on-demand need for fossil fuels. Also changing the grid's infra to support more energy storage is already happening. That being said there is also wind, tidal, and geothermal sources to aid the grid.

Side note, a couple is 2, sometimes a bit more. Where I live there are 9ish hours during the winter and 14 hours a day during the summer. Places like Arizona get sun well over 50% of the time.

To say "I'm not sure anyone is looking" means you didn't take 30 seconds to google. Climate science isn't new, the solutions are tested, we know what we need to do. Oil companies pump millions into lobbying groups to reduce environmental regulations and steer public funding away from renewable sources. We don't need people second guessing renewables because "the sun goes down" and "well maybe setting all this stuff up might be a lot of work." That line of thinking was old in the 2000s and renewable tech has improved 20 years since then.

For now. People are buying the cars, the next step is to improve the grid, focusing on renewables.

I wouldn't say everything, machines are terrible at doing multiple unrelated tasks. Sure a chess machine will beat a GM every time, but it wouldn't be able to make a single move in tic tac toe.

Plus there are plenty of domains where machines play second fiddle. Comedy, sports, acting, distinguishing black people, directing, counciling, coding. We're not at the robot take over yet homie

Cool, I'll drive that when everyone around me decided to also drive much smaller cars with legal bumper heights. Until then I'm not going to risk Chad killing me with his rented full SUV or Tucker with his modded truck that puts his "bumper" at the level of my windshield.

There are safer EVs out there, it's time to upgrade the grid and infrastructure to accommodate these vehicles. Vote, and start writing to your officials that you want green infrastructure.

No, it hasn't.
