Where this collides

• Rests on

  Every doubling of the solar built worldwide has cut its price by 30 to 40 per cent, and that learning rate is why the price keeps falling.

  The forecast that almost all of humanity’s energy is downstream of solar panels by 2042 is an extrapolation, and what it extrapolates is the learning rate. If the 30-40% decline per doubling stops, the date goes with it.
