The accelerating expansion of universe can be described by the non-zerocosmological constant or the dark energy. However, the origin of the darkenergy remains a mystery of modern physics. The local Lorentz invariance is themost exact symmetry of the Nature on the one hand, but all quantum gravitytheories predict Lorentz violation on the other hand. The local Lorentzviolation induced by the quantum gravity at the very early universe may betransformed into large scale by inflation. Combining the low-$l$ anomalies ofthe CMB spectrum, we propose that the local Lorentz invariance may be broken atthe large scale. We construct the effective gravity at the cosmic scale with alocal $SO(3)$ symmetry. The theory exhibits non-trivial contortion distributioneven with scalar matter source. The FRW like solution of the theory is analyzedand the contortion distribution contributes a dark energy like effect which isresponsible for the accelerating expansion of the universe. It reveals that thedark energy may be the remnants of quantum gravity in this sense.
