Relative Danger of Energy Sources


Comparing Energy Sources

1. Put these energy sources for electricity in order of safety, least safe (most deaths/energy produced) first. Coal, hydroelectric, liquefied petroleum gas (LPG), natural gas, nuclear, and oil.

* One TWa is 1 million million watts of electric power provided for one year. A large power plant might be 1,000 MW. One TWa is the amount of electricity produced by 1,000 of these plants operating at full capacity for one year.

Where does this incredible monetary damage for nuclear power (Chernobyl) come from? The report cited (Comprehensive Assessment of Energy Systems: Severe Accidents in the Energy Sector, Paul Scherrer Insitut, 1998):

The estimated costs of the Chernobyl accident cited in [Nucleonics Week, 1994] range between 20 to 320 billion US$ (the range depends on the assumed exchange rate for roubles). It is not clear which cost elements are covered by these estimates.
