No scientific consensus on climate change

I don't really see why ...

No big deal, we're used to it ...

I don't really see why ... in addition, the more we wait, the more techniques improve, for example wind turbines or solar panels are much more efficient now than 20 years ago (obviously that does not solve the problems of intermittent).

and we must also see in what proportion. When we go from an efficiency of 10% to 20% for solar panels, it seems enormous, but it is 20% of not much: 100%, it is 1 KW / m² in full sun one afternoon. 'summer, so not even 100W on average over a year, being very very generous, or 20W given the yield, it's still poor. Even if you count on 100%, it is still lousy, except to cover huge areas with panels, in deserts for example ...

on what criteria?

And I can predict his response from disinformation and liberal denial.

Insults and lawsuits. And on the merits: nothing. Nothingness.

To produce 400 TWh in France, 2300 km2 of solar panels are needed, i.e. in the 5000 km2 needed for shading issues.
There is 9,3% of artificial surface area in France, or roughly 50 km000.
It is therefore necessary to cover 10% of artificialized surfaces.

One m² of solar panels produces € 31 per year at the residential rate and the panel alone costs € 50-60 per m². It remains true that its annual average power is 20W / m².

In northern Europe, solar produces very little in winter and we have the impression that this is a major handicap.
But if we look at the global population distribution, we see that the strong winter / summer effect actually concerns a small percentage of the world's population.

lack of luck, it is the one that consumes the most energy.

In addition, where summer and winter are not very marked (the intertropical zone), there is always around 12 hours of night per day.

The kind of project that does not take into account realities, such as the need to keep all conventional power stations since it is also necessary to provide power at night or during periods of cloud cover ... it would therefore be a mess.

20W, I had done the math with a ladle, not too messy, finally.
I would be ready to take the plunge if I acquired autonomy with solar energy (termination of the EDF subscription). I have already studied the trick. Huge batteries to install, the roof would not be enough for the panels, my home would look more like an industrial site ...

It's completely silly what you're saying. There are still many consumers in a rather solar-favored band, whether in terms of annual global sunshine and a certain "regularity" of the hours of sunshine during the year.
The "ideal" sunscreen is not the same dose for everyone, it depends on each country.

not knowing very well what you call "a lot of inhabitants" and "a certain regularity", I cannot answer you too much. I'm just saying that the inhabitants living in temperate zones with a strong winter / summer effect are globally those who consume the most energy per capita: United States, Europe, Japan, a good part of China.

Namely that in the intertropical zone, there is rather a dry season and a rainy season, and that it is not terrible either for solar, the rainy season.

Anyway, no country has an electricity base with solar, and none will probably ever have one.

I was referring to the data from the number of inhabitants / degree of latitude map published by Enerc a little above. "A lot" because there is no scale so it was a purely visual appreciation, "certain regularity" because in the intertropical zone, and even slightly outside, the summer / winter effect is largely attenuated.

do you think of which country in the intertropical zone consuming a lot of energy per capita?
