Working for an energy company, Scottish and Southern Energy I am always interested in energy information. My Chief Exec runs a blog on our company website and the the article below was posted.
Chris has sent me an interesting calculation. Apparently seismologists have estimated (I don't know how) that the total energy released by the Japanese earthquake was 4 x 10 ^22 joules. That doesn't mean much to me. The interesting bit is to compare that to the energy produced by the 4GW Fukushima nuclear power plant that has been making headline news. It would take that station almost 317,000 years to produce the same energy. Even if every power station in the UK were to run flat out, all the time, it would still take 16,000 years to produce the same power.
As Chris says: another example of how puny human effort is when compared to the power of nature.
