Study Says Nuclear Power Might Be the Cheapest Way to Zero Emissions
New research shows that nuclear power may play a vital role in our quest to lower emissions. To prevent catastrophic damage from climate change, we must keep global average temperatures below 1.5 C relative to pre-industrial levels. Scientists have found that energy production must reach zero emissions globally by 2050 to achieve this goal. Solar…
