We try to reconcile the tension between the local 2.4 % determination of Hubble constant and its global determination by Planck CMB data and BAO data through modeling the dark energy variously .
We find that the chi-square is significantly reduced by \Delta \chi ^ { 2 } _ { \text { all } } = -6.76 in the redshift-binned dark energy model where the 68 \% limits of the equation of state of dark energy read w ( 0 \leq z \leq 0.1 ) = -1.958 _ { -0.508 } ^ { +0.509 } , w ( 0.1 < z \leq 1.5 ) = -1.006 _ { -0.082 } ^ { +0.092 } , and here w ( z > 1.5 ) is fixed to -1 .
