water flows back downhill through a hydro power turbine bridging the shortfall. this one of a kind combination of energy from wind and water is aimed at reaching an elusive goal providing a steady unbroken strain of power even when nature doesn't play along but things haven't worked out quite as planned because the region is earthquake prone the basins had to be built smaller than originally designed providing the entire island with green energy was always an ambitious goal and it still hasn't been reached last year the new facility only generate at forty percent of the power consumed on . the original calculations were higher but structural problems meant those plans couldn't be realized. what really threw them out of kilter with the low water basin which we couldn't build to the size that we wanted. that's now proving a hindrance to producing them not sustainable energy we want. that's disappointed
