Musk said some environmentalists were anti-human for advocating the shutting down of nuclear power plants.

Nuclear energy was discussed by the CEO of the two companies.

Nuclear power should be increased in countries. It is bad for the environment to shut them down.

Scott Morefield said that nuclear is clean, efficient and could replace fossil fuels completely. It's not because environmentalists are anti-human.

Musk said that some are sadly anti- human.

Concerns about the safety of nuclear energy have made it unpopular.

According to a report to US Congress last year, the country has permanently closed 12 nuclear plants. According to data from the IAEA, there are 203 reactor shut downs.

In addition to warning against population collapse, which he said this week is a bigger threat to humanity than global warming, Musk has been a vocal advocate of nuclear energy as a renewable energy source.

In an interview with Insider, Musk said he wanted to be clear. Nuclear power plants should not be shut down, but they should be reopened. Those are the ones with the most energy produced. If you are in a place where there are no natural disasters, it's crazy to shut down a nuclear power plant.

It's more of a question mark if you're in a place where earthquakes happen. There is no danger with the nuclear power plants if there is no huge natural disaster risk.

Nuclear energy was vital until other sources like solar became more reliable, and that shutting down plants was madness according to Musk.
