You opened this thread with "I agree with the left that climate change is a major problem". Yet you are blind that in your canonical example of the effectiveness of nuclear, France, their energy is still mostly powered with fossi

I think you missed the point: without storage nuclear only gets to 70% of the grid, and 31% of the total energy demand. With enough storage to displace oil and gas demand, nuclear has no advantage. It's a pity that France never spent

Do they have nuclear cars in France? It looks like nuclear is actually only 31% of France's energy: https://ourworldindata.org/grapher/energy-consumption-by-sou...

I doubt your numbers then, as when I googled I found “There have been no deaths caused by carrying panels or laying panels on a roof. Electricians are required to connect the panels and inverters as it is.” -- https://reneweconom

The nuclear deaths, unlike all the other sources, also ignores rest of system deaths (e.g. mining, enrichment, transport, construction and decommissioning accidents). Once you include those it looks far more like gas and oil than wind and

I've seen others point out that it's the average that matters for emissions and that was what the other commenter was posting. That makes sense to me, the peak usage only matters for cost reasons, and apparently gas turbines are

Your link shows that AU-SA only used 12% gas in october, and no coal at all.

Solution: in summer we pump the tides higher with PV, and in winter we draw them down.

I think that website is wrong or using obsolete data. I compared with another https://www.pickhvac.com/hvac/furnace-vs-heat-pump-cost/ and it said that with exactly the same numbers the heatpump was 50% cheaper t

$22B / 4.456B = $4.9/W, about 20x more expensive than your number for PV.
