We need fusion energy. However, for the short term, Fission is fine.
That couldn't be further from the truth. Read up on the Thorium-cycle power system, which is incredibly efficient (by-products of various stages can be used in other stages, and the final waste can then be reused).
It's very common in the earth's crust, it's 3 times more common than Uranium, and it's also a lot easier to handle.

"The 2005 IAEA-NEA "Red Book" gives a figure of 4.5 million tonnes of reserves and additional resources, but points out that this excludes data from much of the world."
Over the last 30 years there has been interest in utilising thorium as a nuclear fuel since it is more abundant in the Earth's crust than uranium. Also,
all of the mined thorium is potentially useable in a reactor, compared with the 0.7% of natural uranium, so some 40 times the amount of energy per unit mass might theoretically be available
Hint : 1 ton of pure Thorium is enough to power an ADS reactor for decades. And there are millions of tons of the stuff abundantly extractable.
So yes, we need Nuclear energy, and the Thorium-cycle is the best long-term solution at this point, unless someone breaks open Fusion.
