“This new power…is harnessed for the first time for the common good of our community,” the Queen declared at Calder Hall in Cumberland shortly before pulling the lever that directed electricity from the world’s first full-scale nuclear power station into the national power grid. 24 kilometres north, the town of Workington became the first to receive light, heat and power from nuclear energy. The first nuclear-powered electricity spread to London within four hours. 70 years later, nuclear power continues to be a reliable and low carbon energy source that many countries are considering or have added to their energy mixes.
