So what price should we be aiming for?
Consider an average U.S. coal or natural gas plant that has been in service for decades; its cost of electricity generation is about 4 to 6 U.S. cents per kilowatt-hour. What’s needed are zero-carbon energy sources so cheap that the operators of power plants and industrial facilities alike have an economic rationale for switching over within the next 40 years.

Ok .. so that's the target $/kwh .. the conclusion seems to suggest that target can't be achieved in the next 40 years.
Really ???
Let's look at that ( we won't take 4 years ).

According to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilowatt-hour on the low end and coal at 6.6 cents. Without subsidies, the firm’s analysis shows, solar costs about 7.2 cents a kilowatt-hour at the low end, with wind at 3.7 cents.

Hmmm ... somehow with 40 years of progress .. and 40 years of Fossil Fuel price increasing .. somehow we won't reach the point we are at already today ??
