> Why bother? This is like paying off a debt with low interest early.
Quite the contrary. Once a solar panel is built, you never need to invest into fuel for it, only a tiny bit for maintenance during its lifetime. The energy is provided virtually for free by the sun, gravity or by the aftereffects of Earth's creation many billions of years ago.
A fossil plant, even a nuclear plant, in contrast will require continuous purchases of fuel, of which quite a lot comes from countries that ... aren't really aligned with our Western values.
Reducing CO2 emissions is just a nice side effect.
- skrbjc 3y agoPretty sure most solar panels are also sourced from countries that are not aligned with western values, while Australia is one of the largest producers of Uranium ore and nuclear powerplants are built locally.
- jbarham 3y agoIronically despite Australia being a major producer of uranium, its current Minister for Climate Change and Energy, Chris Bowen, constantly denigrates nuclear power [1]. But that's par for the course in Australian politics ("Australia is a lucky country run mainly by second rate people who share its luck"). 1: https://www.google.com.au/search?q=site%3Ahttps%3A%2F%2Ftwitter.com%2FBowenchris+nuclear https://www.google.com.au/search?q=site%3Ahttps%3A%2F%2Ftwit...
- mschuster91 3y ago> Pretty sure most solar panels are also sourced from countries that are not aligned with western values That's purely a pricing reason, and a bit of a "let's outsource the environmental pollution to China" as well (anything involving silicon tends to use quite nasty chemicals, there's a reason like half the Silicon Valley is a Superfund site). Germany for example used to be the worldwide leader in manufacturing solar panels thanks to a massive subsidy program that kickstarted the industry. Should China decide to cut us off, it's trivial to establish domestic production again - essentially, a solar panel is a bunch of decently purified sand. That stuff is available everywhere on the planet, unlike gas, oil or uranium. > while Australia is one of the largest producers of Uranium ore and nuclear powerplants are built locally. It took the US almost two years to ban the import of Russian uranium [1] despite the Russian invasion of Ukraine. Besides, Australia and Canada are the only two stable, clearly Western-allied democracies out of the 10 top uranium producers and only account for ~18% of worldwide production. The rest is either too neutral for my taste (Namibia, India), failed states (Niger), an active warzone (Ukraine) or some sort of autocracy (the rest). With these circumstances alone, it's beyond foolish to rely on nuclear.

- FredPret 3y agoI'm sure uranium mining releases some CO2 - unless someone invents electric mining trucks (those things are just mammoth and drive slowly, maybe it can be made to work). But a little bit of spicy rocks give off such a ridiculous bounty of 24/7 energy that it's just a no-brainer. We should do solar, wind, and nuclear; in the meantime we can replace a lot of coal and oil with the much cleaner natural gas.
- ben_w 3y ago> unless someone invents electric mining trucks That part's fine; some even charge just from regenerative braking because the ore is at the top of a hill. As for "nuclear?", energy density only matters in a few specific ways like making it easier to tidy away the waste, what most people care about is cost. Good luck to all the teams trying to make nuclear cheaper, but for now that means PV and wind.
- FredPret 3y agoUntil you price in storage / making up the numbers with coal and oil at night
- ben_w 3y agoWind operates at night. Wind and PV are usually good hedges against each other. A 1Ω global power grid is a political rather than technical or economic problem. Batteries are cheaper than you think, and their production is being scaled up rapidly (cars need more than all fixed electricity users). Nuclear isn't too terrible compared to batteries a few years ago, but the current price and forecasts for future prices of each are currently biased towards renewables being cheaper.
- mschuster91 3y ago> We should do solar, wind, and nuclear; in the meantime we can replace a lot of coal and oil with the much cleaner natural gas. Agree on using nat-gas as a bridge to take down coal (especially as peaker plants to cover for low-wind+low-solar conditions) - oil plants are rare anyway and mostly are used as emergency units or to provide district heating. Hard disagree on nuclear though. All major projects for central power plants have massively ran over time and financial budgets - a NPP needs >>20 years of planning and construction, and an additional 20-30 years of decomission/teardown (more if it ends up fucked over like Fukushima or Chernobyl). So, even if we start new projects now, they're politically untenable outside of the US and Australia who have enough place to just dump NPPs hours away from civilization, and by the time they're done we will either have working nuclear fusion or geothermal+chemical storage of renewable power generated during daytime. Decentralized/small modular NPPs are a complete dream at the moment, there hasn't been even a technology demonstrator yet that shows that it is possible to contain high temperature molten salts. > But a little bit of spicy rocks give off such a ridiculous bounty of 24/7 energy that it's just a no-brainer. The discard from mining said spicy rocks is another very problematic issue. While Canada and Australia at least pay lip service to regulations, that cannot be said at all about countries like Kazakhstan [1], Uzbekistan [2], Russia [3] or even Eastern Germany [4]. Reprocessing fuel has also been fraught with contamination issues like in Sellafield [5] or La Hague [6]. The sooner we get rid of nuclear power, the better.

- Gibbon1 3y agoWhen I think of the implications of solar panels I think possession is 9 tenths of the law. Defaulting on loans used to buy solar panels means you still have the panels and the energy they produce. If you can't afford to import oil and gas you're at the IMF's mercy. One other thing if you can use electricity to produce hydrogen for fertilizer you're also more firewalled when the world banking industry mucks up again and the vultures come out.
- fakedang 3y ago> Quite the contrary. Once a solar panel is built, you never need to invest into fuel for it, only a tiny bit for maintenance during its lifetime. The energy is provided virtually for free by the sun, gravity or by the aftereffects of Earth's creation many billions of years ago You still need to maintain a relationship with the largest solar panel producer, which most certainly doesn't align with your Western values.:) On the other hand, going nuclear will only have you deal with Tokayev and Trudeau.
