Do we need nuclear energy to stop climate change? More and more voices from science, environmental activists and the press have been saying so in recent years - but this comes as a shock to those who are fighting against nuclear energy and the problems that come with it. So who is right? Well - it is complicated.

Its green, its renewable- and if regulations make it too expensive than stfu and change it if you care about the earth or energy.

  • 3:42 Yeah, that sounds all well and good but since Ringhals 1 and 2 was shut down in December 2020 and 2019 respectively we had to import electricity generated by fossil fuel and fire up the auxiliary generators that run on diesel to you know, meet demand due to it being winter. So that power plant runs at most at half the capacity now.

  • Solar and wind are really bad for the environment in the sense that wind kills tons of bats and birds just by doing what they do. If you didnt know, bats are incredibly important for fruiting plants to pollinate (and other plants). Solar (depending where you get them but most use the cheap solar bc cheap) have very toxic chemicals that can seriously damage things like the water table and general soil health if they are damaged and leak those chemicals. I dont even need to explain why that is bad. Nuclear is becoming and has been the best and we should be using it. Its just better. But yeah its very hard to transition and it needs to be slow.

  • Yup electricity is like magic :D it is the type of energy that humanity has the most capability to manipulate it . Everything should be electrified but profit making is a great hindrance for it ; many petroleum or coal companies would not like to transition into nuclear or renewable energy due to profit margins. By current trend either the fossil fuels run out or global warming becomes too dangerous ; then humanity will shift towards it. We humans are really the most intelligent+foolish species on earth.

  • Only opinion I have is this. JUST DO IT! Renewable energy and nuclear energy cannot do the jobs alone. And while it's true nuclear energy is responsible for nightmares from the past, that's only because the nuclear energy was weaponized. If it was instead used to push fossil fuels out of the picture we'd already see a vast change in our climates. The truth is this, we best take action, and we best do it soon. Because climate change is not a good thing, and can lead to global extinction. Our governments and our society need to be persuaded that nuclear and renewable energy sources are the future, and it does not matter if they like it or not. Fossil fuels are doing nothing but harming the planet. And we risk the wrath of mother nature the longer we use it.

To have proof of this, we can say that he emptied himself of all his glory and stepped on the earth! Isn't that wonderful? And there's more! He assured us of salvation! He fulfilled the mission that God gave him! Which is to have a death on the cross for all people in the world! * How do I get to heaven? * It's very simple! -Accept Jesus as your Lord and only Savior! - Repent of your sins daily even those you don't know because you sinned out of ignorance! -Recognize that you do not deserve God's salvation but even with your faults He wanted to save you with his great love and grace! Now about keeping your faith -Read the Bible daily -Pray and fast -Go to a church that follows the word of God May God bless you greatly! 👋

  • Nuclear has two advantages. One it could cut back on fossil fuel production by providing an alternate energy. Two if it catastrophically fails it can cut back on fossil fuel use by killing everyone nearby. Win-win. 🤦‍♂️ See here is my problem with nuclear energy. It COULD be amazing if we didn’t make mistakes. But the problem is that we are human, and I just can’t see a world in which I can trust that corners won’t be cut in the name of profit. Or any other number of human errors.

  • Nuclear is the way we could get there fastest and most efficiently at PRESENT understanding. Renewables may improve over the decades but if we want to make radical change fast we need to employ nuclear more. I definitely think the future of nuclear science is to tap into the spent energy until we've found a way to completely utilize every last "drop" of energy left in traditionally considered "spent" fuel.
