Electricity supply has achieved the most significant decarbonisation success in the UK and some European countries - particularly those with nuclear in the mix. But predicted global emissions have still not peaked, making it even more important that countries seeking to identify a route to Net-Zero consider the significant benefits of deploying nuclear, particularly lower cost, small modular nuclear solutions.
Globally, the sources of energy we consume have hardly changed since the 1960s – oil, coal and gas. What has changed has been the amount we use. In 1965 we used 40,000 terawatt-hours of fossil fuels, but by 2019 that had climbed to 136,000 terawatt-hours. in 2019, just 16% of global primary energy came from low-carbon sources including nuclear and renewables. This further emphasises the huge shift that will be required if we are to tackle the decarbonisation challenge in a united way.
