We try to reconcile the tension between the local 2.4\% determination of Hubble constant and its global determination by $\textit{ Planck}$ 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 $-1$.
