Solar Grid Parity: The Great $1 Myth

Very good points about the variability by geography/cost, but you neglected (possibly intentionally) another significant point: if solar (and/or other alternative energy sources) were to provide as much as 20% of our electricity needs ( anumber bantered about as a possibility in the U. S.) demand for fossil fuels would be significantly lower. If the demand for coal/oil/natural gas drops by such a large amount the price for those inputs will also drop significantly because the world would then be awash in excess supply again. In that case, the cost to reach parity would be lowered due to the reduced cost of the fossil fuel inputs. Again, the cost would vary, as you pointed out in your article, by geographyic area, proximity to sources of supply, etc. My point is: the price of grid parity is not only varied buy it is also a moving target.
