Why Nuclear

The Power of Nuclear

Nuclear is a natural component of the strategy to combat climate change.

Westinghouse believes that nuclear energy deserves more recognition for the contribution it makes in today’s and tomorrow’s low-carbon energy system. A decisive move toward the necessary reductions in greenhouse gas emissions can no longer ignore an energy source that:
  • Generates 11 percent of global electricity with 440 reactors;
  • Contributes 30 percent of all low-carbon electricity in the world;   
  • Has prevented the release of more than 60 gigatones (Gt) of equivalent carbon dioxide (CO2eq) between 1970 and 2015 (according to the International Energy Agency’s Nuclear Power and the Paris Agreement, 2016);
  • Has a total lifecycle carbon emissions estimated at 12 g CO2eq/kWh of energy produced;
  • Emits almost 70 times less CO2eq than coal (820 g CO2eq), 40 times less than gas (490 g CO2eq), three times less than photovoltaic (41 g CO2eq), and the same amount as wind power (12 g CO2eq); and
  • Is essentially available 24 hours per day, 7 days per week, 365 days per year.

Westinghouse is committed to fighting climate change. We believe this can be done through development and maintenance of secure and low-carbon energy production that includes nuclear generation.
