  • When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

    If you’ve been told “it’s not possible to have all power from renewable sources”, you have been a victim of disinformation from the fossil fuel industry. The majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable.

    This is all with current, modern day technology, not with some far-off dream or potential future tech such as nuclear fusion, thorium reactors or breeder reactors.

    Compared to nuclear, renewables are:

    • Cheaper
    • As clean or cleaner, in terms of emissions
    • Faster to provision
    • Less environmentally damaging
    • Not reliant on continuous consumption of fuel
    • Decentralised
    • Much, much safer
    • Much easier to maintain
    • More reliable
    • Much more capable of being scaled down on demand to meet changes in energy demands

    Nuclear power has promise as a future technology. But at present, while I’m all in favour of keeping the ones we have until the end of their useful life, building new nuclear power stations is a massive waste of money, resources, effort and political capital.

    Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on building nuclear power plants should be spent on renewables instead.

    Frequently asked questions:

    • But it’s not always sunny or windy, how can we deal with that?

    While a given spot in your country is going to have periods where it’s not sunny or rainy, with a mixture of energy distribution (modern interconnectors can transmit 800kV or more over 800km or more with less than 3% loss) non-electrical storage such as pumped storage, and diversified renewable sources, this problem is completely mitigated - we can generate wind, solar or hydro power over 2,000km away from where it is consumed for cheaper than we could generate nuclear electricity 20km away.

    • Don’t renewables take up too much space?

    The United States has enough land paved over for parking spaces to have 8 spaces per car - 5% of the land. If just 10% of that space was used to generate solar electricity - a mere 0.5% - that would generate enough solar power to provide electricity to the entire country. By comparison, around 50% of the land is agricultural. The amount of land used by renewable sources is not a real problem, it’s an argument used by the very wealthy pro-nuclear lobby to justify the huge amounts of funding that they currently receive.

    • Isn’t Nuclear power cleaner than renewables?

    No, they’re pretty comparable in terms of emissions, and renewables are cleaner in terms of other environmental impacts. You can look up total lifetime emissions for nuclear vs. renewables - this is the aggregated and equalised emissions caused per kWh for each energy source. It takes into account the energy used to extract raw materials, build the power plant, operate the plant, maintenance, the fuels needed to sustain it, the transport needed to service it, and so on. These numbers generally show that renewables tend to be as clean or cleaner in terms of total lifetime emissions, and in addition, since nuclear relies on fuel extraction (mining) and has lots of issues regarding waste, renewables is overall cleaner than nuclear.

    • We need a baseline load, though, and that can only be nuclear or fossil fuels.

    Not according to industry experts - the majority of studies show that a 100% renewable source of energy across all industries for all needs - electricity, heating, transport, and industry - is completely possible with current technology and is economically viable. If you disagree, don’t argue with me, take it up with the IEC. Here’s a Wikipedia article that you can use as a baseline for more information: https://en.m.wikipedia.org/wiki/100%25_renewable_energy



  • So it’s a monetary thing, mainly? If it was cheap would you still want to quit?

    I’m very curious on the topic - having had many friends and relatives who have started vaping, I wanted to get an understanding of the topic, both in terms of health data, but also the perspectives of people who vape.

    It’s incredibly difficult to get good, clear information about this - lots of responses are from smokers talking about how much better vaping is than smoking - but we know that kids/teens have been picking up vaping at a high rate without ever having smoked and have been doing so now for a number of years, so those responses aren’t helpful.

    On the other hand, when it comes to finding the negatives of vaping, it’s very difficult - so much has been written about one or two overblown stories (e.g. vitamin E acetate in THC vapes, or issues involving black-market or gray-market vapes/nicotine solutions) which absolutely drowns out the ability to find information about the negative health effects of a typical vape user buying name-brand products from reputable suppliers.

    Long story short, I’m just trying to gather opinions and personal experience with vaping products. I have no real opinion either way, I’m just looking for the truth.

    If you do want to help people avoid nicotine, all of the research has shown that the best anti-smoking campaigns used storytelling and strong emotional messaging - so I would encourage you to share your story if you’ve had a negative experience with vaping.

    Edit: I just saw your edit saying my questions were a bit specific, it’s possibly my autism or something that makes me inclined to the way I asked, if that helps. It’s genuinely just curiosity, I’m just weird, haha






  • you can’t win against me, who studied at Oxford, Nato boy

    This is the most unbelievably embarrassing thing I have ever read on Lemmy. Honestly, if you regret writing this, please let me know. I will amend my comment to erase the fact you ever wrote it.

    you protect the ROC’s claims

    Please cite evidence of my support of Taiwan’s territorial claims. If you believe that opposing CCP imperialism means that one must also support Taiwanese territorial claims then you have made an incorrect assumption - and a converse error on your part does not constitute a failure on mine.

    I’m very sorry that I refuse to defend the strawman you so thoughtfully prepared for me. By all means, whack away at him. I would suggest that you take your own advice, by the way, and read my actual comment and respond to the text of what I wrote, not some imagined subtext your Oxford-educated brain conjured to allay your cognitive dissonance. Oh, and one last thing - whatever your parents paid for that education, unfortunately it would appear to have turned out a poor investment.




  • Don’t import Reddit’s extremely ignorant takes on nuclear power here, please. Nuclear power is a huge waste of money.

    If you’re about to angrily downvote me (or you already did), or write an angry reply, please read the rest of my comment before you do. This is not my individual opinion, this is the scientific consensus on the issue.

    When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

    If you’re about to lecture about “it’s not possible to have all power from renewable sources”, save your keystrokes - the majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Again, this isn’t my opinion, you can look it up and find a dozen sources to back up what I am writing here.

    This is all with current, modern day technology, not with some far-off dream of thorium fusion breeding or whatever other potential future tech someone will probably comment about without reading this paragraph.

    Again, compared to nuclear, renewables are:

    • Cheaper
    • Lower emissions
    • Faster to provision
    • Less environmentally damaging
    • Not reliant on continuous consumption of fuel
    • Decentralised
    • Much, much safer
    • Much easier to maintain
    • More reliable
    • Much more responsive to changes in energy demands

    Nuclear power has promise as a future technology. It is 100% worth researching for future breakthroughs. But at present it is a massive waste of money, resources, effort and political capital.

    Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on nuclear power should be spent on renewables instead.
