For that purpose, we employ six state-of-the-art nonlinear panel unit root tests with nonlinear dynamics that range from state-dependent nonlinearities such as ESTAR, AESTAR and TAR dynamics to timedependent nonlinearities of structural break form. We find consistent evidence supporting stochastic convergence among high-income and upper-middle-income countries according to two of the six panel tests. Concerning the stronger notion of deterministic convergence, three tests point to deterministic convergence among high-income countries, and only one supports this hypothesis among upper-middle-income countries. Lack of convergence across all country groups carries important policy implications concerning the achievement of SDG7 of the global 2030 Agenda for Sustainable Development that affects every single country in the planet.eninfo:eu-repo/semantics/openAccessPanel unit root testsEnergy consumption convergenceNonlinearitiesTime-dependenceState-dependenceLSTR processESTAR processAESTAR processSign nonlinearitySize nonlinearityStructural breaks2030 Agenda for Sustainable DevelopmentArticleQ1111WOS:000806807100015
