134 Million Horses

BSW Solar reports (in German) that around these days the installed capacity of solar in the World will surpass 100 GW. Thanks to this tweet by Cornelia Daniel for the link.

I think it is easier to actually picture this vast amount of power by using the old unit of “horsepower”. For 100 GW one would need 134 million horses. That’s more than double the current worldwide horse population estimated at 58 million in 2007.

But this is of course only a modest beginning of the story. With prices down massively, in a decade or two we will be talking about TWs of solar capacity.

  1. Which load factor value did you use for the calculation ? It very much depends on the location of the panel, 2011 load factor is around 15% in France and only 10% in Germany, that’s already a big difference.

  2. None. The post above is about peak capacity, not about generation.

    One could do such a calculation for generation as well. I suppose horses have a much smaller capacity factor than nuclear, but a larger one than solar.
