The notion that we need nuclear power to address climate change does not reflect the realities of the marketplace or rapid new developments in energy technology.
It is now generally understood that carbon dioxide emissions from fossil fuel burning are at the centre of the climate crisis. In the electricity sector, that primarily means the burning of coal. China and the United States are the leading users, and Russia, Germany and India also use coal as a mainstay of power generation. Long-term assured carbon sequestration is not yet a proven technology, and it is unclear when it might become available on the required scale. In environmental terms, the world cannot afford new coal-fired power plants; indeed, even existing coal-fired power plants may have to be phased out before 2050. The nuclear-power industry, proclaiming a 'nuclear renaissance', has suggested itself as a saviour with a simple formula: if you don't like coal, build nuclear plants.
