Renewables are unreliable. That's a fact. Yes you have moments, days even weeks where they can deliver what is currently required. In total output. Not yet in delivers when you actually need it output.

Sure you can have 100% renewable generation for a 24hr period, but if your generation is during the day and your usage is spread into the night, you're not really covering your needs, no matter how good it looks on paper.

It is also your current usage. Now do the math and replace all fossil fuel usage with electric alternatives. Cars, buses, trucks, heating, cooking, etc. Now calculate just how much more renewables you need to cover all that in ideal circumstances.

Now do the same for windless winter days.

If we're going to step away from fossil fuels entirely, you're going to have to accept nuclear as an option. Thinking we'll manage only with renewables is a dream. While you dream, we're burning fossil fuels non-stop. Cuz that's reality.

You can have renewables with nuclear, or renewables with fossil fuels. You're actively choosing renewables with fossil fuels.

by insulating the roof of my house better i cut my useage of oil by more than 50%, next time i'll insulate the outer walls, and after that i'll switch to electric heating that would need just 20% of the original energy.

you forget that the energy consumption not neccesarily always rises. All appliances get better and better in efficiency, for example.

Yes, your total energy consumption drops, but your electricity consumption rises as a result. Electrification of stuff that relied on burning fossil fuels means that electricity consumption goes up even while total energy consumption stays the same or drops. I'm not necessarily saying that nuclear is the solution, but it's a solution that can at least buy us a few decades for renewables and energy storage to catch up to demand.

An EV will double your electricity usage. Look into the requirements for EV cargo transport. Swapping out all the diesel trucks, just the heavy transport will come close to doubling the national electricity needs. Add to that small vans and buses.

I urge you to actually do the math. You'll get a much much better understanding of the issue. Just pasting links to articles that look like they support your arguments adds to the dream.

The aim is to drop fossil fuels. Your goal should've been to embrace nuclear while increasing renewables. Atm you seem fine with just burning fossil fuels, killing the planet, cuz the alternative isn't renewable. GG.

Take a look at Germany, Belgium, etc. ditching nuclear because the green parties fought so hard for it. What are they doing now? Back to healthy healthy coal and gas. Thanks for helping kill the planet even faster in your zeal for exclusively renewable energy.

What most people dont' understand, i live in a part of germany, where eating of self collected mushrooms will radiate you, where boars in the forest are radioactive because of chernobyl 30 years ago...

And the massive amount of nuclear tests have had no impact at all? It's all because of Chernobyl. Uhu.

Why are people downvoting this....

There may be a point when we don't need nuclear, maybe once we dramatically level up our battery technology, but that point is not now, and probably not for the next 50 years
