  The energy-energy correlator (EEC) is an observable of wide interest for
collider physics and Standard Model measurements, due to both its simple
theoretical description in terms of the energy-momentum tensor and its novel
features for experimental studies. Significant progress has been made in both
applications and higher-order perturbative predictions for the EEC. Here, we
analyze the nature of the asymptotic perturbative series for the EEC by
determining its analytic form in Borel space under the bubble-sum
approximation. This result provides information on the leading and subleading
nonperturbative power corrections through renormalon poles. We improve the
perturbative convergence of the $\overline{\mathrm{MS}}$ series for the EEC by
removing its leading renormalon using an R scheme, which is independent of the
bubble-sum approximation. Using the leading R-scheme power correction
determined by fits to thrust, we find good agreement with EEC OPAL data already
at ${\mathcal O}(\alpha_s^2)$.
