Wind and solar are not "available now."
They are trivial and useless forms of energy, soaking up trillions of dollars for no tangible result.
The United States remains the world's largest provider of nuclear energy, relying on reactors built in the 20th century by engineers lacking access to modern computational power. The willful destruction of US nuclear manufacturing by people who, as I often describe them, "arsonists complaining about forest fires" was a crime against all future generations.
The nuclear industry produced in a climate of mindless criticism and attacks, 30 EJ of primary energy in 2023, whereas the useless solar and wind affectation combined, produced just 16 EJ of primary energy, all of it dependent largely on access to dangerous fossil fuels. They can't even keep up with the growth of dangerous fossil fuels.
I have never met an antinuke who can tell the difference between 16 and 30:

Advocates of so called "renewable energy," have never given a flying fuck about fossil fuels. Their entire goal has been to attack nuclear energy relying on specious and ignorant criteria.
Their indifference, moral and intellectual, to sustainability killed people, in vast numbers, since nuclear energy saves lives:

Nuclear energy need not be risk free to be vastly superior to all other forms of energy. It only needs to be vastly superior, which it is.
