wind power -- effeciency? Wind Power Puffery

This is relating to the article Wind Power Puffery by h sterling Burnett

do wind turbines really use less coal, in regard to output electricity ??

how much less coal do they use than a power plant?

in comparison to the same amount of energy output, not per plant per minute.

for example

to output the same amount of electricity
over 2 days, how much less coal will a advanced wind farm use,

and is that amount worth switching over (enough to make a significant difference?)


How true is the article?? Ultimately id like a scientific figure if someone can tell me exactly how much less coal a wind turbine uses comparatively to the same energy output, in a percent or fraction

feel free to ad any critque of the article or the information in it as well

thank you
