Someone should have bought the Japan Times a calculator for Christmas

In this story on solar power, we see the following facts in a single paragraph:

Oita-ken will have a new 81.5 megawatt solar plant, which is 30,000 homes-worth.

Oita-ken already has a 70 megawatt solar plant, which is 70,000 homes-worth.

Osaka will soon have a 19.6 megawatt solar plant, which is 5,700 homes-worth.

One doesn’t even need a calculator to notice that 10 megawatts less can supply over twice as many homes, or that the Osaka one is a quarter of the size of the first, but can only supply a fifth of the houses. There really ought to be a standard way of expressing solar power (peak or averaged or potential) and a standard house power consumption.

 Oh, and Happy New Year to all (bar one) of my readers!

  1. Osaka homes draw more power for those takoyaki grill sets, didn’t you know?? :razz:

  2. Most such errors in news articles can be traced back to someone, perhaps a person with a journalism degree, not knowing the difference between “electric demand” and “energy demand” in the original material.

    Home energy demand includes everything; heat, hot water, cooking, lights, aircon, appliances, etc.. Some of that can be done with gas, the rest electric. Roughly 50/50 ratio on average.

    So a given solar energy plant could supply both 10,000 homes’ energy demand, and 20,000 homes’ electric demand.

  3. I was wondering if you ever considered changing the layout of your website?
    Its very well written; I love what youve got to say. But maybe you could a little more in the way of
    content so people could connect with it better.
    Youve got an awful lot of text for only having one or 2 pictures.

    Maybe you could space it out better?

  4. aaaaaaand if you click that link you get taken to a gay African American short film review Indonesian dating site about Star Trek. Seriously.
