To　understand　the　nexus　between　economic　growth　and　energy　sources,　in　this　study,　we　have　selected　Pakistan　and　collected　data　over　the　period　1980-2016.　The　neoclassical　production　function　of　Pakistan　is　augmented　with　conventional　and　renewable　energy,　capital,　and　labor.　Conversely,　the　conventional　and　renewable　models　are　being　constructed　by　using　GDP　as　an　independent　variable.　This　paper　applied　linear　and　nonlinear　ARDL　models　to　see　whether　the　influence　of　conventional　and　renewable　energy　consumption　on　GDP　per　capita　of　Pakistan　is　symmetric　or　asymmetric　and　vice　versa.　Furthermore,　the　asymmetric　causal　effects　between　the　energy　variables　and　economic　growth　are　also　discussed.　From　the　findings　of　the　study,　we　deduce　the　long-run　asymmetric　effects　of　renewable　energy　on　the　economic　growth　of　Pakistan.　Similarly,　the　asymmetric　effects　of　GDP,　in　the　long　run,　are　confirmed　in　both　energy　models.　The　symmetric　and　asymmetric　causality　results　have　recommended　growth　and　conservation　hypothesis.　The　findings　propose　that　renewable　energy　is　a　significant　factor　in　boosting　the　economic　growth　of　Pakistan　and　a　decline　in　the　use　of　renewable　energy　could　actually　stem　the　economic　growth　of　Pakistan.
