What Can I Do About It?

Contact your state representatives! Explain to them why safe, emissions-free nuclear energy is critical to helping California do its part in addressing global warming.

Facts:

San Onofre Nuclear Generating Station (SONGS), located on California’s coast near the city of San Clemente, began generating electricity on January 1, 1968 and was shut down June 7, 2013.1
During its lifetime, the plant generated 486 trillion watthours of energy2 without emitting any CO2, a global warming gas. For comparison, how much CO2 would have been emitted using other fuels to generate the same amount of energy?3
  • Natural gas: 97 million tons, equivalent to 313,000 additional cars on the road for 45.5 years4
  • Gasoline: 130 million tons - 421,000 additional cars
  • Coal: 189 million tons - 613,000 additional cars
The geographical footprint (land area) of SONGS is .4 square miles5. How much geographical area is required to generate the same average electrical power using other technologies?
  • Gas, combined cycle gas turbine (Astoria, Queens NYC) - .39 square miles (slightly less area)6
  • Solar, utility photovoltaic in California (Topaz) - 98.1 square miles (245 times more area)7
  • Wind, offshore (London Array) 259.5 square miles (649 times more area)8
Through 2019, the U.S. Department of Energy estimates the cost for new nuclear energy at $96 per megawatthour9. What are the estimated costs for other carbon-free technologies?
  • Wind, onshore - $80/MWh
  • Wind, offshore - $204/MWh
  • Solar PV - $130/MWh
  • Solar Thermal - $243/MWh
Though electricity provides incalculable benefits to society, generating it involves risk. Nuclear energy is the safest way to generate electricity, resulting in .04 fatalities per trillion watthours of generation. What is the safety record of other electricity generation technologies?10
  • Wind - .15 fatalities/TWh
  • Solar, rooftop PV - .44 fatalities/TWh
  • Hydro - 1.4 fatalities/TWh
  • Natural Gas - 4 fatalities/TWh
  • Biofuel/Biomass - 12 fatalities/TWh
  • Coal - 60 fatalities/TWh
The estimated cost to repair to San Onofre, excluding warranty compensation from the manufacturer of the defective steam generators, is $800 million. The cost to decommission the plant and replace the energy it generated is estimated to be $13.6 billion, borne by ratepayers11.
Due to improved operating efficiencies over its lifetime, closing SONGS will result in 8 million tons of additional carbon (or equivalent greenhouse gas) emissions every year - about the same as 1.6 million extra cars on the road12.
