The future of nuclear energy is in cogeneration, according to a policy briefing released on October 7 by the United Kingdom’s Royal Society. (The equivalent of the United States’ National Academy of Sciences, the Royal Society, founded in 1660, is the oldest scientific institution in continuous existence.)

Cogeneration, the briefing explains, occurs when the heat produced by a nuclear power plant is used not only to generate electricity, but also to meet such energy demands as domestic heating and hydrogen production. It also allows a plant to be used more flexibly, switching between electricity generation and cogeneration applications.
