Google image search on "energy source carbon footprint" and see that even the charts with very low carbon impact estimates for nuclear still place it at roughly twice wind, and more than solar.
Look at what power companies, investors, grid operators, and most countries are putting money into. Not nuclear. If you think it's just because the public finds it unpalatable, well, the public finds a lot of things unpalatable and that doesn't stop industry and investors from doing whatever they want.
Solar and wind deployment in the US is growing massively as the price of solar panels and wind turbines plunge, especially solar. Battery storage is also plunging in price and rapidly maturing into grid-scale solutions like flow batteries.
Nuclear hasn't gotten cheaper over many, many decades and it provides a kind of power we don't need - base load. In many countries there's an excess of renewable power on many days.
Solar is highly distributed which helps decentralize the grid and localize power generation, lowering losses. It's a lot more efficient for your EV to get power from your neighbor's rooftop panels than from a power plant hundreds of miles away.
