We included solar panels and a battery when we built our new house in Tokyo, and even though it’s in a quite shadowy area, I’m surprised how much power we get out of them (even on cloudy days). Switching to an EV now too. It’s an absolute no-brainer.

Serious questions for people not looking to play political whack-a-mole and slapping people around online.

I haven't taken the time to research - but is the "solar overtaking nuclear" because of the dramatic increase in solar farms? Or primarily from the increase of tech? I imagine an mix of both, but the quantity increase seems to be significant.

Are nuclear plants as efficient as they can be? Or are most of plants decades old with problems from aging?

Can the rise of solar be more person to person investment? Or is it's increase mostly from huge cap ex from people wanting to own and charge for the energy? Nuke is obviously a huge expense begining to end.

And if Republicans weren't such greedy assholes we'd have been here decades ago

You mean we can make FREE ENERGY in our BACKYARD for almost NO Money? This is TERRIBLE!

-LITERALLY Conservatives!

Don't y'all know everything is made from oil and this is why we should keep burning the stuff to never see it again?

-Also LITERALLY Conservatives

I heard Hunter's laptop ran on solar energy!!

Turns out we already have fusion power, it's just been placed safely 149.6 million km away. The solution to energy independence comes up every morning.

[–] Doomsider@lemmy.world 1 points 1 hour ago

I know you are joking, but we have several commercial fusion plants that are in the construction phase.

Now you know why Big Oil is pushing so hard for massive profits. Between renewables and fusion the energy landscape is going to change dramatically.

149.6 million km

how many American hotdogs is that?

Well you know what they say about the length of your sausage. If it can't reach Venus, then what's the point, really?

[–] LodeMike@lemmy.today 12 points 8 hours ago (8 children)

All energy comes from the sun except for geothermal which comes from the Earth's rotational momentum which might as well be the sun because it wouldn't rotate without something to orbit around.

[–] cecilkorik@piefed.ca 23 points 7 hours ago

Technically nuclear came from a different star. The sun won't create those kinds of heavier elements until it burns through its hydrogen and helium fuel to start fusing its way up to lead, and I don't think it's massive enough to actually reach the kind of supernova collapse required to smash lesser elements together into heavier elements than that in any significant amount. So technically, fission is the only the form of energy that isn't based on solar. It's just the still-cooling-embers leftover from someone else's dying star, a whole bunch of billions of years ago. I guess you could say the sun's gravity at least attracted it all into this general vicinity though, at least until the Earth's own gravity started pulling its own weight.

[–] Felis_Catus_Domesticus@lemmy.world 5 points 7 hours ago (1 children)

except for geothermal which comes from the Earth’s rotational momentum

emm that is not the source of geothermal energy..

[–] TehWorld@lemmy.world 3 points 6 hours ago

TIL - according to one source 80% of the geothermal energy comes from radiation and the remaining 20% is from the sun.

While I consider myself pro nuclear, there is something that gets forgotten everytime this conversation comes up.

Nuclear produces waste, which is mentioned often but it is usually responded by pointing out that it could be recycled and the worse to be buried.

Here is what people miss:

Are all our nuclear waste handled correctly today? If not then why should we imply that they will be in the future.

The problem with nuclear isn’t that the waste is impossible to handle, it’s that humans are too short sighted to follow through with it.

And imo that’s a very valid argument on why we should use solar as much as we can.

[–] IndustryStandard@lemmy.world 17 points 8 hours ago (3 children)

Being pro-nuclear was a very valid position up until a few years ago. Now solar has gotten so cheap that there is practically no reason to do it except to protect yourself against US imperialism.

[–] jacksilver@lemmy.world 5 points 4 hours ago (2 children)

Solar still has some huge problems when it comes to seasonality and day/night cycle. You either need massive battery build out or some other form of energy to handle base loads and/or offset when solar isn't producing enough.

Not saying solar isn't part of the future, but we literally can't just rely on solar.

[–] Joelk111@lemmy.world 3 points 3 hours ago

Battery tech is getting super good though, and the materials are recyclable. If solar becomes cheap enough we could even store it in creative (but less efficient) batteries like lake batteries or weight batteries and the like.

[–] Nouvellalia@lemmy.world 1 points 3 hours ago

This isn't a problem at City scales and beyond. You just can't buy a bunch of nazi batteries so there isn't a corp greasing politicians to build it.

[–] HugeNerd@lemmy.ca 5 points 6 hours ago (1 children)

Nuclear, both fission and fusion (which will never happen anyway) are relics of an era of cheap fossil fuels and relative world order.

Solar electricity is viable at scale but also indicates a change in our species' living arrangements on this planet.

[–] Doomsider@lemmy.world 2 points 1 hour ago

We are started to build the first commercial fusion plants now. You may want to update your rhetoric.

[–] nforminvasion@lemmy.world 6 points 7 hours ago (1 children)

You do realize that you can support multiple things? You don't have to be antinuclear to be pro-solar.

[–] IndustryStandard@lemmy.world 1 points 4 hours ago

You need to choose a thing to build there is not unlimited budget.

The problem with nuclear isn’t that the waste is impossible to handle, it’s that humans are too short sighted to follow through with it.

Thats not even the biggest problem with nuclear power as the waste angle, at scale, will hit us decades in the future. The more urgent problem hitting us now on even on existing deployed nuclear plants is cooling water.

The byproduct of nuclear power generation is lots AND LOTS of waste heat. You have to get rid of this every second to continue to produce electricity. This is why nuclear power plants are typically built next to a large body of water. However, with reduced water supplies in reseviors theres less water to use for cooling nuclear plants. A double whammy is with climate change increasing temperatures, the water that remains is already hotter than it was, meaning it can carry away even less heat.

If a plant can't get rid of its heat it needs to curtail (reduce) electricity production. This isn't just theoretical. Its happening now in 2026 to existing power plants:

At the time when Europe was experiencing its worst heatwave is recorded history, many European reactors had to be turned down or off. 2026 isn't the first time this has happened either, you can go back in the last 5 years or so and see many reports of nuclear plant curtailment because of lack of cooling capacity (cool water).

When we know global temperature are rising, it looks like this will just get worse. How can we say nuclear is the future when the conditions for it working well are already declining?
