New testing conducted at France's oldest PV system have shown that its solar modules can still provide performance values in line with what the manufacturers promised.
No, because until we solve the storage issues with electricity. You need a reliable baseline power source in the grid. Solar has 0% cost effectiveness at night.
Nuclear is 100 times more environmentally friendly than coal. Even with the long term waste storage issues.
This has already been solved with the use of diversified power sources, on and off-grid storage, distributed power grids and dispatching. We could shift to a 100% renewable energy source for all of our energy needs with current technology. It just needs investment. This isn’t my opinion by the way, it’s scientific consensus supported by the IEA.
This has not being solved. There’s not a single country in this world that has managed to not rely on hydro, nuclear, fossils or importations for electricity generation.
Please provide those “studies and researches” that backup your claim, because a simple calculation shows that the world’s largest WWTP, Hongrin-Leman (100GWh in capacity and 480MW in power, over a 90km² basin) contains just 10% of the capacity needed and only 0.7% of the power required for a country like France to last a winter night (~70GW during ~14h of night).
So we’d need “only” 10 Hongrin-Léman stations in terms of capacity, but 142 Hongrin-Léman stations in terms of power. In other words, we’d need to flood at best 8.5x the surface area of Paris, and at worst the entire surface area of the Île de France department, home to 12 million inhabitants. And that’s just for one night without wind (which happens very regularly), assuming we rely on solar and wind power.
Then we need to find enough water and enough energy to pump it to fill the STEP completely in 10 hours of daylight, otherwise we’ll have a blackout the following night.
Wind and solar power cannot form the basis of a country’s energy production, because they are intermittent energies, and the storage needed to smooth out production is titanic. These energies rely on hydroelectricity, nuclear power and fossil fuels to be viable on a national scale.
That’s some nice fanfic you wrote but I don’t think we should base our real world decisions on your little ideas.
It’s very easy to find this information so I can only assume you’re arguing in bad faith, but regardless, here are a few starting points for your research. You could also maybe just search it yourself instead of wasting my time and yours with your ridiculous example of a single hydroelectric dam.
Hi babe thanks for asking, I read some news articles about the studies and I skimmed the studies themselves but I haven’t actually read them. Have you read them? Is there something fun that you’d like to share? Excited to hear more xx
That’s some nice fanfic you wrote but I don’t think we should base our real world decisions on your little ideas.
Point the flaws in my logic, debate my ideas, or just leave. Don’t waste your time making another reply if you can’t keep respectful, I won’t bother reading it.

Asking for sources and data to support a disputed claim is the basis of scientific debate. Becoming aggressive and disrespectful after such a mundane request is much more revealing of who is debating in good faith here.
TLDR : The study does not support the claim made in the title. It just says that it will be economically feasible. When asked about if its physically possible, they just throw some vague techno-solutionism, and even admit that 100% renewable will may never be actually possible
This report does not even relate to our debate at all, it theorizes multiple scenarios for 2050, does not tell if it’s feasible and how, and none of these scenarios are 100% renewables anyway. This is out of subject.
I’m not going to bother to keep going, it becomes obvious that you just took random studies whose title seemed to support vaguely your points , hoping that I’m as bad-faith as you and I that I won’t open them.
Your statements are based on void and you become aggressive when asked for explanations. I take back what I have above: don’t bother to answer at all, I’m just going to ignore you from now on.
We’ve basically solved the storage issues through about eighty different methods that have various applicability in different situations. They just need to be scaled up at this point.
It’s actually better. No traditional power plant can match demand exactly, and large amounts of power are wasted as a result. A wind+solar+storage solution can match demand very close. This means we don’t need to replace every GWh of coal and gas with a GWh of renewable. The lack of wasted power takes off a pretty big chunk.
No traditional power plant can match demand exactly, and large amounts of power are wasted as a result
Absolutely false. Power consumption is very stable and previsible, plants can react in minutes, and the surproduction is small enough to be stored or exported.
The French electricity system operator, RTE, provides all the information on this subject:
I brush it off because nuclear has exactly the same problem. Worse, actually. We know what happens when you build solar, wind, and storage: on average, things get built on time and in budget. We also know what happens when we build nuclear: it doubles its schedule and budget and makes companies go bankrupt. One is way easier to scale up than the other.
If all the paperwork was done and signed off today, there wouldn’t be a single GW of new nuclear produced in the US before 2030. Even optimistic schedules are running up against that limit.
React to demand in minutes? Cute. Because most energy storage works by being pulled by demand directly rather than reacting to it, things change almost instantly.
This is critical because it means we don’t have to replace a GW of fossil fuel generation with a GW of renewables. The difference between demand and supply all but disappears. You don’t have that for nuclear, though, because it doesn’t react that way. In fact, it’s preferred if they only provide baseload that never changes.

No, just no.
We know what happens when we build nuclear:
We invest 140 billion.
We build more than two reactors a year for 25 years.
By building up skills and an industry with projects, you can even put 1 plant and 4 reactors in the same place in less than 7 years from a vacant lot (Blayais power plant) .
We decarbonize almost all of its electricity in two decades.
It runs smoothly for more than 50 years.
You don’t rely on fossils and the dictatorships that sit on it anymore.
We become the biggest electricity exporter of Europe for decades, and the biggest of the world most of those years too
It’s called France.
We also know what happens when we want to do without nuclear when we don’t have hydro-electricity:
We invest two trillion of euros.
25 years later we have 60% renewables, but we’re still burning coal and gas.
so we are still one of the most polluting electricity in Europe
We’re always at least six years away to get out of coal.
We don’t have a date to get out of the gas because we have no idea how we’re going to build enough electricity storage to make renewable to work
Can you tell me how much green countries do you see which does not rely on hydro and/or nuclear?
The answer is: >!not. A. Single. One. Even after trillions of euros invested in it worldwide, not one country managed to reduce their electricity carbon print without nuclear or hydro.!<
If all the paperwork was done and signed off today, there wouldn’t be a single GW of new nuclear produced in the US before 2030. Even optimistic schedules are running up against that limit.
Why this arbitrary date? In five and a half years, there would be no power plant, but if you launch 15 1GW projects in parallel, maybe it will take 15 years to build because of legal recourse as well as a shortage of engineers/technicians because people have been told for 30 years that nuclear is Satan and we want to stop. But after 15 years you have 15GW of nuclear.
But how long before we find a solution for storage? How much will it cost? Is it even possible to store so much energy with our space constraints and physical resources?
The debates and even this thread are filled with “we could totally go 100% renewables with political will and investments”. No you could not, that’s called wishful thinking. In reality you can’t force your way through technological innovation by throwing money and gathering political will, or else we would skip renewables and go straight to nuclear fusion.
On thing that money and political will can help with, on the other hand, is to speed up and reducing costs to build nuclear. But somehow, you act like nuclear is inherently too slow to build, before an arbitrary date that you forget conveniently when we’re talking about renewable storage. It’s called hypocrisy and double standards.
React to demand in minutes? Cute. Because most energy storage works by being pulled by demand directly rather than reacting to it, things change almost instantly.
I just proved that your theory is wrong by bringing up empirical data gathered over a whole country, why do you keep insisting?
No, because until we solve the storage issues with electricity. You need a reliable baseline power source in the grid. Solar has 0% cost effectiveness at night. Nuclear is 100 times more environmentally friendly than coal. Even with the long term waste storage issues.

Hydroelectric plants, batteries, generation on site, wave power, geothermal, … There are lots of ways to reduce the need of non renewable energy.
We’ve basically solved the storage issues through about eighty different methods that have various applicability in different situations. They just need to be scaled up at this point.

“We totally can go to Mars, we have engines, they just need to be scaled up at this point”
Scaling up is almost the entirety of the problem that needs to be solved, you can’t just brush it aside like this.
Check my comment that shows the scale of the problem
Absolutely false. Power consumption is very stable and previsible, plants can react in minutes, and the surproduction is small enough to be stored or exported.
The French electricity system operator, RTE, provides all the information on this subject:
Real-time consumption and production by region
Real-time forecasting and consumption
