Radioactive waste is an unavoidable by-product of nuclear power that requires safe storage.
A facility processing uranium ore into nuclear power plant fuel can process the ore into fuel for a nuclear weapon instead.
Nuclear power results from radiation, which was discovered around 1900. It took several decades after that for scientists to understand how to harness its energy Ã¢Â€Â“ for power and for weapons.
Over 400 nuclear reactors are operating today in the world in 30 different countries.
Nuclear power emits much lower greenhouse gas emissions than electricity from coal but there is risk of a reactor accident, unresolved issues with radioactive waste disposal, and weapons.
The energy released from the nucleus of an atom Ã¢Â€Â“ nuclear energy Ã¢Â€Â“ is harnessed today by heating water to make steam. The steam turns a turbine that drives a generator to make electricity.
Carbon capture and sequestration or CCS is a technology that can remove carbon dioxide emitted by a power plant and store it underground. Climate Central visits the site of a proposed coal plant in Linden, NJ to find out how it is done.
No scientist disputes that carbon dioxide is a greenhouse gas and that it is increasing in the atmosphere. And careful detective work shows that the increase has chemical fingerprints Ã¢Â€Â” from us.
