▁predict or ▁of ▁production . ▁The ▁biggest ▁cost ▁occurred ▁in ▁wind ▁far ms ▁are ▁for ▁the ▁tur b ines ▁themselves . ▁With ▁tur b ines ▁varying ▁in ▁size , ▁the ▁smaller ▁tur b ines ▁are ▁used ▁at ▁a ▁more ▁local ▁and ▁person ▁level ▁are ▁more ▁expensive ▁on ▁a ▁per ▁kil ow att ▁of ▁energy ▁capacity ▁rate , ▁while ▁larger ▁ones ▁are ▁less ▁expensive ▁on ▁these ▁dynamics . ▁Wind ▁far ms ▁look ▁at ▁the ▁total ▁area ▁of ▁power ▁it ▁can ▁produce , ▁for ▁a ▁ 5 0 0 ▁M W ▁wind ▁farm , ▁nearly ▁ 2 0 0 , 0 0 0 ▁wind ▁far ms ▁can ▁be ▁generated . ▁Many ▁question ▁whether ▁having ▁a ▁small ▁number ▁of ▁tur b ines ▁would ▁still ▁be ▁benef icial ▁or ▁not , ▁and ▁worth ▁the ▁cost . ▁The ▁inter mit ten cy ▁costs ▁of ▁tur b ines ▁show ▁that ▁the ▁are ▁less ▁than ▁one ▁percent ▁of ▁the ▁price ▁of ▁the ▁wind ▁energy ▁price . ▁This ▁is ▁shown ▁by ▁detail ing ▁that ▁the ▁addition ▁of ▁more ▁tur b ines ▁throughout ▁an ▁area ▁increase ▁the ▁inter mit ten cy ▁of ▁individual ▁tur b ines , ▁allowing ▁the ▁far ms ▁with ▁a ▁lower ▁supply ▁to ▁gain ▁by ▁another ▁farm ▁with ▁larger ▁supply ▁of ▁tur b ines . ▁Small ▁resident ial ▁and ▁small ▁commercial ▁have ▁the ▁most ▁profit ability ▁due ▁to ▁their ▁low ▁energy ▁cost ▁and ▁short ▁pay back ▁period . ▁Specifically , ▁this ▁becomes ▁more ▁prof itable ▁with ▁a ▁ 1 0 ▁kW ▁system . ▁ ▁Social ▁As pect s ▁
