Nuclear is fine, and being used, but you have to find a way to get rid of the waste or spent fuel rods used by the plants. Right now they bury it underground. Which can contaminate water, rivers, livestock, food, etc. The only other alternative is to build nuclear plants that use nuclear waste (Molten Salt Reactors). Otherwise the waste has to get boarded on rocket. With a one way trip to the sun or to outer space and crash it into another mass or planet. <– Easier said than done because there is so much of it. What happens if the rocket doesn't make it to space and falls back the earth? Clean energy (solar / wind) is the only viable option if you view climate change as a serious problem that needs to get addressed. Trump is just a idiot on climate change.
