If I'm reading the figure in the article correctly, 1GWh/month of electricity works out to something like 1.34 MW average load. That much electricity could be supplied by a total of three (1.5MW nameplate) utility-scale wind turbines, at least if you assume the capacity factor (0.3-0.35) seen in the upper midwest.
Put differently, that is about 1/10 of the average electricity consumption of the (midwestern, state) university where I studied.
