Stewart Brand 4 : Debate: Does the world need nuclear energy?

Stewart Brand + Mark Z. Jacobson at TED 2010
Debate: Does the world need nuclear energy?  (transcript)
Summary
I was surprised that many people were in favor of using nuclear energy. However. this subject was debated in 2010. I think that people would change their minds after the nuclear accident in Fukushima, Japan, in 2011.

Does the world need nuclear energy?

Stewart Brand is in favor of this and engaging this. He is an environmentalist.
Thus he tells us that from an environmental standpoint, the waste from nuclear is far lesser than from coal. 1)
Now, energy sources of coal, gas and hydro are maxed out but solar, wind and the other renewables are still not enough, 2) and the better small reactors must be developed soon. 3)
Now, even decommissioned warheads become our electric energy. 4)
Then nuclear energy is clean energy and many countries distinguish nuclear weapons from nuclear energy. 5)
The audiences who are in favor said that the risks of overheating the planet outweigh the risk of nuclear incident 6) and people should recycle nuclear weapons. 7)

Mark Jacobson is against nuclear.
He has the detailed calculations of the relative impacts of different energy sources. It shows that wind and concentrated solar have lowest CO2. 1)
The construction time of nuclear power plants is much time. While we're waiting around for your nuclear, we have to run the regular electric power grid. It becomes the opportunity cost. 2)
Those time must be used to develop wind and concentrated solar energy. 3)
Nuclear weapons proliferation is definitely associated with nuclear energy proliferation. 4)
And then an audience said that the propaganda shouldn't show that only nuclear is safe 5) and renewable energies are still not enough. 6) Before the better small reactors must be developed, the world must not have disastrous nuclear power but new alternative energies soon. 7)

I understand that the meaning of both wins. We have to use only both advantages, thus the study of renewable energy and its use have to be progressed more. It includes recycling nuclear. In Japan, we can't hear the discussion about renewable energy, even now in 2018.
