Nuclear energy provides about 2-3% of the total end energy worldwide.
But reserves are nearly exhausted by 40-50% in the last about 70 years. So nuclear energy has far less potential than per example one tenth (10%) of all fossil fuels.
Compared with dangers and costs, this is a disaster, far away from being hope.
Tho only reason for developing nuclear energy was military reasons for all times. There was no further reason, as alternative nuclear concepts were dismissed decades before, not producing militarily usable material.

I am convinced, that we have to reduce fossile dependency. But why does nobody speak about energy efficiency? What about passive houses. What about smaller cars? What about long during products, we needn't to replace every year?

Perhaps it would be better not to panic and to think for environmentally solutions, not only regarding CO2!

#1 That's cute. Much of what you're talking about is nipping at the fringe and it's not being serious. I do agree with less usage of raw materials, though no one values well made items. Toss the one you got and buy another. Trading with 3rd world countries makes it easy.

4:03 using a nuclear barge to power extraction of fossil fuels. That is hilarious.
