Solar Power Is Becoming a LOT Cheaper

cheap solar

 

Current estimates suggest that solar might be as cheap as coal by the end of the decade, and half the cost of coal by the end of the next decade. When applied to electricity prices this predicts that solar generated electricity in the US will descend to a level of 12 cents (7 pence) per kilowatt hour by 2020, possibly even 2015 for the sunniest parts of America. (hat-tip, SilverIsTheNew blog)

The 90s were a funny time for solar. I assume that’s the effect of higher silicon prices caused by an increase in the demand for computers?

Can we really call this “exponential”?

Yes. Plotted in log space it makes a fairly straight line for economic data.
