ADVANTAJES Its a renewable energy Wind turbines have low cost High perfomance is achieved Reduce energy dependency on fossil
fuels.

ADVANTAGES AND DISADVANTAGES
ADVANTAGES: HAVE MINIMUM MAINTENANCE, CLEAN DOES NOT GENERATE WASTE AND HELP CONTROL FLOODS AND PROVIDE WATER FOR AGRICULTURE.
DISADVANTAGES: THEY ARE FAR FROM LARGE TOWS AND WATER QUANTITY DEPENDS ON TIME, THE CONSTRUCTION OF RESERVOIS INVOLVES THE
FLOODING OF THE DAM.
