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

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
