Facts and figures about Jiminy Peak wind turbine

The giant wind turbine on Jiminy Peak in the northern Berkshires has been on line for 2 months and has already broken down. At this rate, they won't even save their (our) investment, let alone the planet.

Type: General Electric 1.5-megawatt model SLE

Heights and weights
Base tower section: 72', 64.5 tons
Midsection: 85’, 47.5 tons
Top tower section: 97', 33.5 tons
Total tower: 253' (77 m), 144.5 tones
Nacelle: 12'2" high, 61.7 tons
Blade (x3): 122' long, 9'2" wide, 11.2 tons
Hub: 11' radius
Total blade assembly: 249' diam. (81 m), 134.6 tons, swept area 1.27 acres
Total: 386' (117.5 m), 236 tons

Foundation: 412 cubic yards of cement; 40' diameter; 8' deep in rock; 25 tons of reinforcing rod; 140 8’ anchor bolts

Likely output of this behemoth (when not broken down): about 325 kilowatts annually, reaching that rate or above only a third of the time, essentially idle another third of the time
