Green Energy

It's less about building new and more about not shutting down old. But building new nuclear would also be a great deal better for the environment than building more coal- and natural gas-burning power plants, even if deployment is over a longer timespan. Solar panels only last a few decades, by the time the nuclear plants are done being commissioned the first waves of solar panels being installed today will already be too old. We don't need enough built to singlehandedly cover our energy needs, we just need enough to price out fossil fuels for good. Nuclear is supplemental to renewable.

And about putting up the funding, the whole point is to sway public opinion so public funds get used how the public wants them to be used. Nobody is relying on private investors to make the change carbon-free electricity while coal is still the cheapest option for reliable power.
