As an island nation surrounded by water, we will also aggressively explore renewable opportunities afforded by our geography and geology, including tidal and geothermal. And we are actively exploring the potential for international projects to provide clean, affordable and secure power, for example by expanding the Contracts for Difference scheme. Low-carbon nuclear supplies 15 per cent of our electric lifeblood as a steady source of generation to complement intermittent renewables. Nuclear is the only form of reliable, low carbon electricity generation which has been proven at scale and returns more than a hundred times as much power as a solar site of the same size. We can only secure a big enough baseload of reliable power for our island by drawing on nuclear. Our aim is to lead the world once again in a technology we pioneered so that by 2050, up to a quarter of our power consumed in Great Britain is from nuclear. When Her Majesty The Queen opened the world's first nuclear power station at Calder Hall in Cumbria in 1956, she described being present at the making of history. The UK had indeed led the world as the first country to split the atom, and the first to pioneer this new form of power.
