To combat climate change, the world needs to transition to low-emission energy sources like nuclear, despite challenges in cost and innovation. The debate lies in whether to invest in nuclear technology alongside renewables or solely focus on renewables for a sustainable energy future.

The debate on the necessity of nuclear energy to combat climate change is complex, with varying opinions on its role in reducing greenhouse gas emissions. Despite concerns about cost, safety, and waste, nuclear power remains a low-emission energy source that can play a significant role in the global transition to cleaner energy.

The chapter discusses the challenges of transitioning from fossil fuels to electricity, emphasizing the need for massive storage capacities and controllable load sources to ensure reliability. While renewables are seen as the future of electricity, they still face significant hurdles before completely replacing fossil fuels.

The chapter discusses the dilemma of whether to prolong the lifespan of existing nuclear reactors and eventually decommission them, address the limitations of renewables, or opt for new, more cost-effective and safer nuclear reactor designs. It explores the debate on whether to prioritize immediate nuclear phase-out to curb emissions or pursue a dual approach to tackle rapid climate change.
