A bold and groundbreaking call to harness the untapped potential of nuclear power to tackle our global climate and energy crises, from a leading chemist at the National Nuclear Laboratory What if climate change isn't an environmental challenge, but an energy challenge? In this visionary book, Dr Tim Gregory urges us to rethink the path to net zero. He argues that the solution to climate change lies not simply in replacing fossil fuels with renewables, but in fully embracing another energy source that emits zero carbon dioxide- nuclear power. Gregory dismantles the conventional wisdom that renewables such as wind and solar are completely 'green', and debunks myths surrounding nuclear waste and radiation, demonstrating that nuclear power is not only reliable, safe and potent, but the most environmentally responsible way to harvest energy. Going Nuclear calls for decarbonisation to be the twenty-first century's Apollo programme. By interweaving scientific optimism, myth-busting data, and ambitious policy ideas, Gregory illustrates the boundless potential of the atom beyond just clean energy- from advanced medicine and forensics to atomic gardening and space exploration. This is a bold case for an alternative, sustainable and prosperous future- a world in which abundant energy is available to all.
