Bill Gates states it clearly.
Nuclear will be needed for full decarbonisation. Intermittent sources will not be able to provide all our power. The vast amount of storage for that would be too expensive (more expensive than including new nuclear).
This apprently still needs to be said. We are regularly treated to arguments that nuclear is a waste of money, because renewables are simply cheaper, period, based on simple LCOE comparisons that only apply at low penetration levels (i.e., to not include the cost of significant storage and or grid upgrades).
The reason for the rapidly growing worldwide interest in nuclear is that everyone is figuring out what Gates has. Renewables alone will not be enough, and we need to expand nuclear. Just ask the IPCC and other formal scientific organisations.
